Silicone sealant for the bathroom. What sealant is better to use in the bathroom? The best silicone sealants

The bathroom is a premises with a special climate. It constantly occurs in temperature and humidity drops, and the ventilation is not always sufficient. These factors lead to the appearance of fungi, mold and other harmful microflora. It is for this reason that it is important to figure out which sealant is better to use in the premises of this type.

There is an extensive selection of sealants with various composition and properties. For bathrooms builders apply such types of sealants:

Acrylic;
Polyurethane;
Silicone acrylic.

The choice of the right material will give confidence that the joints are reliably protected from the penetration of moisture and microflora development

Acrylic

The cheapest sealant is acrylic. The composition does not contain harmful substances, which allows you to work without protective agents. Its feature is that the acrylic sealant is perfectly in contact with the wood and minerals (plaster and putty, concrete, brick). Good adhesion allows you to qualitatively handle the joints of the surfaces. But it is noted that such seams are not elastic enough for use in places that are subject to deformations.

Acrylic sealant is applied without effort uniform and thin seam, which acquires operational properties after 24 hours. Acrylic withstands the effect of UV radiation and retains its qualities even when the temperature reaches eighty degrees Celsius.

Acrylic retains the initial color for a long time, it is amenable to coloring and plaster. But the melting point does not allow to use this type of sauna and bathrooms.

Polyurethane

Polyurethane sealant is more often used when re-seeding seams over old materials. It is well connected with any bases and finishing materials, while creating a smooth and reliable seam. Work with polyurethane compositions using gloves and respiratory masks.

Makroflex is one of the popular silicone compositions on the market.

Silicone

Silicone sealant is the most popular type of sealants with a long service life. Silicone is well in contact with concrete, brick, plaster, glass, wood, metal and other building materials. Manufacturers indicate that silicone sealants are able to maintain properties and after forty years after applying. Many silicone compounds withstand a large temperature and have a melting threshold above two hundred degrees Celsius.

Combined

Silicone acrylic sealant combines positive properties of both types. It is elastic, resistantly withstands the impact of moisture and has an increased melting point. This composition is used in the processing of seams, to stick mirrors or hangers on the walls.

When working with a gun, it is easier to apply a uniform layer.

Properties of silicone sealants for the bathroom

There are quite a few varieties of bathroom sealants. Many manufacturers produce a silicone version that is marked as "for a bath" or "sanitary". Such formulations are suitable for the processing of seams in places of contact with the walls with walls, sealing of sewer joints and water pipes.

In these sealants add components that help resist moisture, increase the melting point, add anti-grab properties. An important factor is the level of shrinkage of the substance. In high-quality compositions, it is practically absent and does not exceed the norm in 2-3%.

Manufacturers produce various color gamas that will help you choose silicone under the color of the tile and plumbing

The volume of additional components in the bottle should not exceed 10%. Some producers sin with abundant mixing in the composition of various additives, which only reduce the durability and strength of the silicone substance. Useful additive is a fungicide. Such a component opposes the spread of mold and fungi in conditions of high humidity.

Many manufacturers are added to the dyes. They help to choose a color that does not stand out on the background of a wall or plumbing.

Silicone sealants are produced in two different versions: acid and neutral. The second form is applied on any surfaces, but it is more expensive. If we are talking about acid silicone, then it is also called acetic. The composition includes acetic acid, which helps to harden. The cylinder is capable of oxidizing the surface of the metals. Therefore, its use is allowed only with stainless steel and aluminum alloys.

Which manufacturers are worthy of attention?

Silicone compounds for the processing of seams differ in purpose, the conditions of use and characteristics that depend on the manufacturer.

Tubik from the company "Moment", which is enough for processing a small area

Famous and popular manufacturers: Penosil, moment, Ceresit, Tytan, Soudal, Makroflex. These companies have developed an extensive line of silicone sealants for various needs. Many firms are ready to provide and choose from the volume of the tub. After all, it is not always appropriate to acquire a capacity with a volume of 310 milliliters. In addition to these firms, there are less well-known companies in the construction market, among which there are deserved attention.

Tips for choosing from an expert:

Choosing from little-known companies, pay attention to the composition of the substance, the stated properties and the reviews of those who have already worked with the products. Then you will be sure about the processing of the joints. After all, sometimes it is better to buy a reliable and proven product, even if its cost is higher than that of cheap alternatives with dubious quality.

When repairing in the bathroom, there is a need to use sealing compositions. It is necessary to prevent water from entering the gap between the bathroom (shower cabin) and the wall, between the sink and the wall. It may also be necessary to fill cracks in the material of the wall, interputric seams, sealing of pipe connections, furniture edges, etc. For these purposes use sealant for the bathroom. You can choose, but you need to know which compositions are and what they differ from each other.

To begin with, it is worth talking about the form of release. The bathroom sealant in stores can be found in several types:

The most convenient option is in tubes under the construction gun. For independent work, this is the optimal choice.

Acrylic

These are the cheapest sealing compositions that simultaneously have good specifications:

In general, good quality, especially if you consider low cost, as well as harmlessness. It is possible to work with acrylic sealants without protective products, and a small time required not to cure, accelerates work. Their disadvantage - shrinkage during drying. Because of this, in contact with the water, the seam begins to leak, so that such a bathroom sealant is better to use in those places where water does not count. Also before applying for better adhesion requires primer surfaces (under acrylic). In this case, there is more chances to get a non-pending seam.

Application area

The main disadvantage of acrylic sealants is the rigidity of the seam obtained. Even with small extensions, it bursts. That is, apply it to protect the joint of a steel or acrylic bath (showerful pallet) with a wall is not worth it. Under the load, they change their dimensions and that the seam does not collapse, it must be elastic.

Excellent are suitable for filling emptiness and cracks in various building materials (brick, concrete, etc.), compounds of stationary or sedentary compounds (slots between the jammer and the brick or concrete wall, seelings in the pipes, etc.). These compositions are treated with unprotected edges of furniture, which is installed in the bathroom, suitable for filling the joint of the sink with a wall.

Another unpleasant moment: in a humid environment, fungi and bacteria are well multiplied on the surface of the usual acrylic sealant. This disadvantage is eliminated by the presence of antiseptic additives, but for zones that constantly in contact with water acrylic sealants are better not to use.

And one more thing: in the bathroom acrylic quickly changes the color - it starts shroud. Therefore, it is not worth using white. Better color (there are such) or transparent. On them, color changes are not so visible.

When choosing it is necessary to remember that acrylic sealants can be waterproof and not. Acrylic sealant for the bathroom should be waterproof. Even in those zones where water cannot contact him directly, but due to high humidity, moisture can be absorbed from the air.

Stamps of acrylic sealants

There are a lot of good brands. Only for the bathroom you need to watch the composition be moisture-resistant.

Bison acrylic. There are several different compositions: super fast with drying in 15-30 minutes, universal - can be used to seal wood.
Bosny Acrylic Sealant;
Boxer;
DAP Alex Plus. This is an acrylo-latex composition with greater elasticity and additives from fungi.
KIM TEC SILACRYL 121. Polyacrylate moisture resistant and elastic sealant. Can be used in the zones of long-term contact with water.
Penosil. To fill the seams and cracks that are not in direct contact with water.

There are still a lot of other brands and manufacturers. Many acrylic sealants have special additives that change their properties. If you are satisfied with the harmlessness, you can find the composition even for direct contact with water.

Silicone

A rather popular type of sealing compositions. In composition can be acidic and neutral. Acid is easier in production, it is cheaper, but it is difficult to work with them in closed rooms - a strong smell before the rejection. The second negative moment is acidic - when applied to the metal, it is quickly oxidized. Therefore, it is not worth using steel and cast-iron baths to use it. Neutral silicone sealants do not react with materials, because their scope is wider. But the production technology is more complicated and they are more expensive.

Silicone bathroom sealant - good solution

Like acidic sooths and neutral silicone sealants can be waterproof and not. Only waterproofs are suitable for the baths. They are also one-component and two-component. For private use, single-component are mainly used, since they do not need to mix before applying.

Properties and scope of silicone sealants:

The main advantage of silicone sealants - after the polymerization of the seam remains rather elastic. It does not crack and can be used to seal the joint acrylic or steel bath with a wall. The disadvantage is the susceptibility to the appearance and reproduction of the fungus. It is solved by adding antiseptic additives. To prevent the development of mold and fungus, it is better to use silicone sealant for aquarium or special plumbing. Both of these species have antibacterial properties.

Stamps and prices

Silicone bath sealant today is popular and in any store there is a completely decent range.

As you can see, there is a very large scatter in prices. Dear sealants (Ravak, Ottoseal. Lugato) - production of Germany, Denmark, Czech Republic. According to reviews, they have excellent quality - used for several years unchanged, the fungus does not multiply on them. They are presented in the widest range of colors.

Not bad serve inexpensive Ceresit, Tytan, Soudal. These manufacturers have a wide range of both acidic and neutral silicone sealants. There are other types (acrylic, polyurethane). On them, too, good reviews for use as a bathroom sealant - a joint with a wall.

Polyurethane

Polyurethane sealants are good with outdoor use. They are not afraid of temperature drops and humidity, well tolerate ultraviolet. They can be operated on open or closed, but not heated balconies and loggias. Also their properties are in demand in wet premises - bathroom, toilet and kitchen. The main advantage - they have a very good adhesive ability, for which they are called more adhesive gel.

Properties and scope

Polyurethane-based sealants can be used on the street, they can be applied at minus temperatures (up to -10 ° C). And this is the main difference from others. They also possess the following qualities:

Disadvantages are also there. The first is low adhesion with plastics, which leads to the low strength of the seam. Secondly, it is impossible to use in zones of elevated temperatures (heating above + 120 ° C is prohibited). The third one should be applied on dry surfaces (no higher than 10% humidity). When applied to wet materials, pre-primer is necessary.

Low adhesion with plastics imposes restrictions on the use of polyurethane sealants in the bathroom. They are good for sealing a joint or cast iron bath with a wall, porcelain or glass sink. But for or the shower cabin should not be used - the seams can flow.

Manufacturers, brands, prices

Polyurethane sealant for the bathroom compared to acrylic is the best choice. It remains elastic, does not crack. When compared with silicones, it is definitely difficult to say that it is better. The advantage of silicones is that they are good "liput" even to plastics, and polyurethane compositions in the fact that they do not have odors.

Name	Colors	Special properties		Release form and volume	Price
Bostik PU 2638.	white, Gray, Black, Brown	high adhesive ability	45 min.	Tube pistol 300 ml	230 rubles
Polyflex-LM low module	white gray	resistant to ultraviolet and water, not applied to glass	15 minutes	Pistol tube 310 ml	280 rubles

SOUDAFLEX 40 FC.	white, Gray, Black	takes out and quenching vibration	15 minutes	Tube pistol 300 ml	290 rubles

This type of sealing compositions relates more to general construction. Many compositions are ideal for sealing interpanel seams in high-rise buildings and for other similar works. The bathroom sealant is one of the uses.

Sealants with MS polymers

Recently emerged type of sealants, which, thanks to excellent properties, is quickly gaining popularity. They combine the qualities of silicones and polyurethanes, reliably protecting against the flow, forming elastic and reliable connections.

VS polymers - excellent quality bathroom and other wet rooms

Properties and scope

The main advantage of sealants based on MS polymers is plus to the properties of the sealant they still have a high adhesive ability, therefore their polymers are called more adhesive sealant. They have the following properties:

Excellent properties. There are disadvantages. The first is a high price, but it is justified, since the seam does not crack and does not proceed for a long time. The second - after a while the surface of the white sealant can yellow. On the quality of the seam, this does not affect, but it looks ugly. Remove the yellowness can be rubbed with peeled gasoline. The third minus - after the hole, the composition is removed only mechanically. No solvents do not work on it.

Manufacturers and prices

MS sealants are practically every major manufacturer, and they also have with various additives that give special characteristics, so you can choose exactly in terms of the situation and for a specific type of work.

Name	Color	Special properties	Formation of surface film	Form release	Price
BISIN MS POLYMER (Glue Sealant)	white / transparent	Glass, Mirrors, Plastics, Brick, Natural Stone, Concrete, Tree, Iron and Many other metals.	15 min at + 20 ° C	Tube under gun (280 ml)	490-600 rubles

SOUDASEAL FIX ALL HIGH TACK	white black	For sanitary premises, super strong initial fixation	10 min at + 20 ° C	Tube under gun (280 ml)	460 rubles

Despite the fact that this type of sealants appeared recently, the range is solid, since the combination of high adhesive ability and sealant properties is very convenient and the product is in demand.

The main advantage of MS sealants is elasticity after drying, tolerability of long-term direct contact with water, countering the reproduction of fungi and bacteria. Because this type of sealant is used to seal the junction of a bath or shower with a wall. In the case of the shower cabin, it is good and the fact that it does not slip with vertical application.

Another positive point - most of the compositions have a pasty consistency, which falls at exactly, does not bubble. After applying to primary rejection (film formation), the applied sealant can be easily loosen, giving it the desired form.

What bathing sealant is better

You need to choose the type of sealant under specific tasks. Then you can choose the optimal properties. For example, for sealing a joint of a bath or shower with a wall with a wall is the best choice - a sealant based on MS polymer. Not bad - silicone and polyurethane. But they must have antibacterial supplements.

For gluing mirrors, the neutral silicone sealant is perfectly suitable. Any silicone (one can and acid) is deprived of cutlets, edges and sections of furniture, which is installed in the bathroom or in the kitchen.

If you need to glue the falling tile in the bathroom, a polyurethane composition is suitable or with MS polymers. Due to the high adhesive ability, they immediately fix the product on the spot. Since the compositions during drying do not give a shrinkage, the risk of damaging the tile is also not.

The main problem is blackening from fungus. Resolves the presence of antibactericidal additives

If you need a sealant for the bathroom for sealing pipe connections, you need to look at the material from which they are made. For pipes made of steel and cast iron, neutral silicone, polyurethane and with MS polymers fit. For plastic and metal-plastic polyurethane, it is better not to use, and silicone compositions are suitable for any.

When designing the walls, it is usually coated with moisture-resistant hyposphate. But since the house constantly "plays" in height, there is a gap between the ceiling and GLC - compensate for these changes. So that there is no moisture there, it must be filled with something, but in this case, the seam remains elastic. For these purposes, silicone and MS polymer compositions can also be used.

To solve the problem with reprimanding seams, it is necessary to choose compounds with antibacterial additives. There are also special sanitary sealants. They are so named precisely because of the presence of additives against fungi and mold. For these purposes, sealants for aquariums are also suitable. They have excellent adhesion with most materials and never black.

As you can see, for each type of work, the best sealant for your bathroom, but the most universal - on MS polymers.

The bathroom refers to rooms with high humidity. That is why when carrying out repair and finishing works, it is necessary to select the appropriate materials that are resistant to moisture. An important stage in the process of decoration is the sealing of seams through which moisture can be leaked, as a result, fungus and mold is formed. Earlier for these purposes, special grouts of different shades were used, but now in a construction store you can find a more attractive offer - sealant. A fairly large range leads the consumer into confusion, because it is not known which bath is better? The answer to this question can be found in this article.

Main species

Sealants are chemical compositions, the appointment of which is to protect seams and joints from moisture. The composition includes all sorts of compositions made of polymers with a variety of modifying additives. To determine what is better, it is worth examining the entire classification.

This is the most common group of sealants, which is greater popularity. It is caused by increased water repellent properties, long-term operational deadlines and good adhesion.

Acid (acetic). The affordable price makes it more attractive to consumers, but it is worth considering that there are some restrictions on the use. So, due to the entry, it is not recommended to use it for metal surfaces - it contributes to oxidation. It can only be used for elements made of stainless steel.
Neutral. During production, acid is not used, which allows it to be used for all types of surfaces. It affects the cost - it is higher than the cost of the previous analogue. Neutral is particularly recommended for acrylic elements, in particular, baths. It can be used at almost any temperature, because it perfectly transfers even sharp temperature differences.

In addition, it is worth allocating another classification of silicone sealants:

aquarium;
sanitary;
colored;
adhesives;
construction.

Each of them has its own purpose and scope. So, if you need to decide on the choice of aquarium or sanitary sealant, it is necessary to take into account that the first species is used when gluing and sealing glass surfaces (for example, aquariums), and the second - for plumbing, water supply and sewer systems.

Silicone compositions have a high water resistance rate. It is easy enough to use it, which allows you to cope with the work even a newcomer.

Acrylic

Advantages and features of this category also a lot:

practicality;
affordable price;
high adhesion rate of almost all types of materials, even porous;
no unpleasant odors.

The latter was possible, due to the absence of organic solvents, and therefore, it is possible to work with a mixture without special means of protection (respirators). After a day after applying, the layer will dry completely. In stores you can find two types of sealants: moisture-proof and unstable. The second group is not recommended to use in the bathroom, so it builds its attention to the first group.

To decide which to buy, acrylic or silicone, it is necessary to determine all the types of surfaces that will need to be treated with the protective composition.

An essential disadvantage of acrylic-based sealants is the low elasticity of the coating. It is possible to use it only for surfaces that will not be subject to deformation.

Silicone Acrylic

Sealants are considered a combined option, which includes both acrylic and silicone. Thanks to this combination of materials, it is practically deprived of all the shortcomings that are in the analogues described above, but at the same time he retained all their advantages.

As a result of applying the solution, an insulating coating is formed, which has such positive characteristics as:

strength;
durability;
moisture resistance;
elasticity.

If you want to protect the surfaces from mold, then this category is best suited. The upper layer is most resistant to the formation and spread of the fungus.

In some cases, this group of sealants can be used as glue. The two elements are securely connected to each other and simultaneously seal.

Polyurethane

In production, innovative polyurethane mixtures are used. The process of polymerization is activated at the first contact with air, as it contains moisture. The positive parties of this group of sealants should include:

ease of use;
efficiency;
durability;
small shrinkage percentage;
high adhesion (to all types of surface);
strength;
maintainability.

When working with this type of sealants, the manufacturer recommends taking care of the protection of the skin of the hands - enough to arm rubber gloves.

Even after exposure to moisture, the layer will only become stronger, this type of insulator is absolutely not afraid of mechanical damage and deformation. When working with a polyurethane sealant, it is necessary to take into account that it is quickly grasped and hardens, so all actions should be clear and neat. If you opened the packaging, then it is necessary to fully use it, otherwise the remnants harden.

It is worth noting that this species can be applied as glue if necessary to glue small fragments or repair cracks. After complete drying, the seams are painted or lacked.

In addition to the above sealing types, there are other, for example, bituminous and thiocoles, but for our purposes they are not suitable, so we will not stop on them.

Select the composition for the bath

To finally disassemble how to make a bathroom, you need to pay attention to the following:

High-quality sealant should, first of all, have an increased water resistance.
If there is a marker "Sanitary" on the product you can use it not only for finishing materials, but also for sealing plumbing. In the manufacture of manufacturers complement the composition of antibacterial and antifungal additives, which are aimed at confronting the formation and development of fungi.
Take into account when choosing that the composition can be color, white or transparent.
In addition to the above varieties, it is worth considering that such materials can be professional and intended for household purposes. Newbies in repair and finishing works prefer the second group, as it will be much easier to work with them.

To date, there are several most common stamps in stores. This is the "moment of sanitary" and "Titan Sanitarian". If you need to pick up the composition for working with plumbing and plastics, then learn the brands on which there is a mark "for acrylic and PVC."

When choosing a sealant for a bathroom, you must consider only three main criteria:

resistance to mold and fungal formations;
not cracking pasty (gel) consistency;
adhesion to all types of materials and surfaces.

In order not to make a mistake in the choice, it will be enough to stop your choice on popular brands that have proven themselves from the positive side.

The bathroom is a room in which a wet environment. Therefore, when repairing this room, you need to choose materials that are resistant to water action and thoroughly seal all the joints, correctly using the bathroom sealant. Otherwise, soon the walls and other surfaces will cover the fungus, and the presence of mold in housing is harmful to health. What variant sealant will help in the fight against mold?

Damp in the bathroom is not only the risk of premature destruction of decoration and building structures. The fact is that the wet atmosphere favors the growth of mold, and this fungus distributes disputes that can provoke serious health problems.

To avoid the appearance of mold and withdraw an existing fungus, you need to get rid of dampness. And in the conditions of the bathroom, it is difficult to do it. The need for seams between plumbing is well known, but what sealant is better for the bathroom?

Why is the mold grow?

The fungus is a frequent problem of bathrooms. How many troubles occur due to the appearance of mold fungi! The growth of mold contributes to the increased dampness in this room, since the fungus "loves" moisture and warmth. To get rid of mold, good ventilation is needed. However, the room has places where the fungus "feels" perfectly. This is a space under the bath.

If there is a gap between the bathroom and the wall, then water will fall into it, which in this place will not dry for a long time, contributing to the growth of mold. To defeat the fungus and get rid of mold, sealing seams in the bathroom you need to pay special attention.

Types of bathroom sealants

Sealant It is customary to call compositions from polymeric materials with various modifying additives. Depending on the base material, the silicone, silicate, acrylic, bituminous, rubber, thiocol or polyurethane sealants for the bathroom differ.

Silicone

The most frequently used material is a silicone bath sealant. They differ in a long service life and excellent adhesion to materials of various types.

The basis of the material is silicone. It has excellent water repellent properties, perfectly tolerate temperature difference, so silicone sealants can be operated in the temperature range from -50 to +200 degrees. You can find a sealant silicone sealant for a bathroom of two types:

Acid or, as they say, acetic. It is distinguished by an affordable price, quickly dries, but in the process of vulcanization it contributes to the oxidation of metals.
Neutral. It is more expensive, but devoid of acidic deficiencies. Applicable for acrylic bath, as well as for any metal surfaces.

Acrylic

Acrylic sealant is cheaply and convenient to use, as it lies smoothly and dries quickly. But the coatings of it do not have high elasticity. Therefore, this material can only be used in those places that are not exposed to deformation during operation.

The sealant contains organic solvents, so it does not have a sharp smell. You can find moisture-proof and non-fat. Naturally, the performance of the bathroom repair should choose the first option.

Silicone Acrylic

This material includes the positive qualities of silicone and acrylic sealant. Coatings are durable and simultaneously elastic. Therefore, if the bathroom is repaired, the sealant of this type will perfectly cope with the tasks set before him.

Polyurethane

With this composition, you can create a durable and elastic coating. They are distinguished by good adhesion to various materials. Polyurethane formulations can be used to perform repairs of seams created by silicone counterparts.

Tip! As for other varieties of sealants (bituminous, thiocol, etc.), they are usually not used for repairing a bathroom.

How to choose a sealant?

Which sealant is better to choose to protect against mold? Here are the qualities that the appropriate material must possess:

Good sealant for the bathroom, first of all, waterproof.
Well, if the bathroom acquires a sanitary composition. Sanitary contains antibacterial and antifungal supplements that help to deal with the development of mold.
Sealants can be transparent, white or colored. This should be considered when choosing.

It will not hurt to find out when buying how much the composition is dry. The answer to this question depends on the composition of the sealant.
As for the grade of sealant, it should be known that the compositions are professional and intended for domestic use. Among the most popular brands "Moment Sanitary", "Titan Sanitarian". For sealing plumbing made of plastic, you need to choose the compositions with the mark "for acrylic and PVC".

How to apply sealant?

After the material is selected and purchased, you can proceed to performing seams.

Necessary materials and tools

To perform work, you will need:

Pistol mounting.
Little rubber spatula.
Alcohol or acetone for degreasing.
Rag.
Scotch larger.

Tip! The acquisition of an assembly pistol is extremely desirable, since, using a screwdriver (for example, a hammer handle), it will be difficult to put the sealant smoothly.

Preparatory work

If the sealing of the joints is made after the repair, the preparation is to clean and degrease the surfaces. If the seal is reused, then you will need to remove the old coating.

If there is a black flare on the surfaces, then the fungus already "settled" in the bathroom. In this case, it is not enough to unleash the flare, you need to apply a means destroying the fungus. Otherwise, the black raid will soon appear again. The next stage of preparation is degreasing the surface and its drying. After that, you can proceed to seams.

Application sealant

You can apply sealant to clean and dry surface. It is put smoothly, continuous line, without skipping and thickening. And how much does the sealant dry in the bathroom, because until a complete drying of the composition you need to exclude the water from entering it?

The answer depends on the composition of the drug. Silicone and acrylic dried out per day, polyurethane compositions - for 8-10 hours. So, the answer to the question, how much the bathroom cannot be used, depends on the type of sealant.

After seam sealing is completed, a plastic or ceramic corner can be glued over the sealant layer. Plastic corner can be glued with liquid nails glue, ceramics products are fixed on tile glue, which is used to masonry the tile.

The easiest way to glue the plastic corner is the easiest. We will figure it out how to do it right. First prepare the surface, then measured the corner. Now you need to apply glue on the corner and attach it to the installation site, tightly pressed to the surface. How much do you need to hold the corner? It will have to keep until the glue dry, so you should choose a glue composition that dries quickly.

Several more difficult to glue a ceramic corner. The fastening of this part is carried out on the tile glue, as well as the usual tile. After drying the tile adhesive, the wiggle for seams is used.

So, the best sealant to seal seams in the bathroom is distinguished by moisture resistance, durability and the presence of fungicidal additives. When choosing a tool, it is worth a preference to which there is a "Sanitary, intended for use in wet rooms".
