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. For optimal choice, you need to know which compositions 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:
- In the usual tube to which the cap with a cone-shaped nose is attached. Mass composition - 60-100 grams. It is clear that a small amount of composition is sometimes required. But to squeeze out of such a tube, a smooth strip of sealant will not work. You have to raise, align, rub.
Forms of release of hermetic
- Tuba under the construction gun. Have a larger volume - 280-320 ml, can be large - 500-600 ml. It is easier to work with them as it is easier to control the effort. It is also necessary to correct, but much less.
- Packaging in an aluminum tube (sausage), buckets of various tanks and barrels. In private house-building is not used, these are professional volumes.
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:
- Does not contain dangerous and toxic components.
- Chemically neutral.
- Good adhesion to most surfaces (concrete, brick, plastic, glass, metal, wood and its MDF derivatives, chipboard, plywood).
- Temperature range from -20 ° C to + 80 ° C (there is with a wider and narrow range).
- Withstands long-term vibration with a small amplitude (used in mechanics and mechanical engineering during installation of devices).
- After the polymerization of the seams inelastic, the destruction begins when stretching 10-12%.
- Fast drying.
- The dried surface can be painted or varnished.
The use of acrylic sealants in the bathroom is limited by zones where there is no direct contact with water
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.
Acrylic sealants are good for filling cracks
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
Properties and scope of silicone sealants:
- Possess good adhesive ability. It can be used to seal the joints of stone and plastic windows, when installing washing and other devices in the worktop.
- It is used to seal the joints of the glass, non-porous building materials (metal, plastic, glass, wood, ceramics), plasterboard adjoining to the ceiling, drainage pipes.
Silicone bathroom sealant - good choice
- Different with increased tolerability of high temperatures, can be used to seal the seams around chimneys.
- Racks to water can be used to seal the insoles of bathrooms and shower cabins, shells and other plumbing devices.
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.

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.
Polyurethane compositions are good for everyone, but have a weak adhesion with plastics
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:
- Elasticity after drying.
- Water resistance.
- No shrinkage when drying (no deformation and cracks in the seam, it remains hermetic).
- Well adhesive with brick, concrete, stone, glass, metals, wood, etc.).
- Many compounds after drying can be painted.
There are colorless compositions. Seam turns out more accurate
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 to install an acrylic bath or shower cabin, you should not use them - the seams can occur.
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 | Formation of surface film | 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 |
| PolyureThane 50 FC. | white | Quick-drying, suitable for gluing plastic, corrosionly resistant steel | 10 min | Pistol tube 310 ml | 240 rubles |
| Makroflex PA124. | white | water resistant, weak acid solutions | 25 min | Tube pistol 300 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 adhesion with all construction materials without the need to use primers.
- Do not contain solvents, safe and practically without odors.
- Quickly dry and harden even at minus temperatures (only slower).
- When drying, do not harden, remain elastic (the range of elasticity is 25%).
- After drying, you can paint.
- Under the influence of the Sun, they do not crack and do not change the color.
- Waterproof, can be used in fresh and salted water.
- When applying does not spread, on vertical and horizontal, inclined surfaces are easily formed by a neat seam.
Can be applied to horizontal and vertical surfaces
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 |
|---|---|---|---|---|---|

| 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 placing a bathroom in a wooden house, the walls usually be squeezed by moisture-resistant hyposkard. 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.
