How to choose a sealant for the bathroom that does not blacken

Sealant is a polymer designed to process joints between different types of surfaces. You can not do without it when arranging a bathroom. If the joints between the plumbing and the tiles are not sealed, water droplets and condensate will accumulate in them, becoming a favorable environment for the growth of mold. Due to high humidity and temperature differences, all materials used in the bathroom have special requirements. We will consider what is the best sealant for the bath to choose, and also find out how to apply it.

Silicone

The most popular and expensive is silicone sealant for the bath. Its properties:

• provides adhesion to almost all materials
• shows resistance to moisture, temperature extremes, ultraviolet,
• after drying, it shrinks by a maximum of 2%,
• due to elasticity it can be used for sealing joints in movable structures,
• retains its characteristics for a long time,
• available in a wide range of colors,
• it is applied to internal and external works,
• after application it hardens for 30 minutes, hardens after 6-48 hours (the exact time depends on the types of sealant, layer thickness, temperature and humidity in the room).

Silicone sealants are acidic and neutral. The former are characterized by a “vinegar” odor and are not suitable for processing metal products, such as bathtubs, as they can damage (oxidize) their coating. Acidic preparations are used to seal joints of wooden, plastic, ceramic and glass surfaces. Neutral sealant is more expensive than acidic, but can be used when working with any materials.

A type of neutral agent based on silicone is a sanitary sealant for the bathroom, its peculiarity is the presence in the composition of the fungicide - a substance that inhibits the reproduction of fungi. Such a preparation is indispensable for sealing joints that are constantly in contact with water - at the joints of plumbing and walls / floor, in between the tiles of the tiled apron of the bathroom. It is about sanitary silicone that experts say, answering the question of which sealant is best for the bathroom.

Acrylic

Acrylic sealant for a bathroom is cheaper than silicone, but it serves less time. Its properties:

• withstands temperature extremes,
• does not fade
• characterized by high adhesion to various materials,
• on top it can be coated with paint, varnish, putty (unlike silicone),
• does not have elasticity, it cannot be used for joints with a risk of deformation,
• hardens within 24 hours.

Acrylic sealant is convenient to use for:

• filling the space between stone, brick and concrete surfaces,
• stickers of the ceiling plinth in the bathroom, while it will smooth out the roughness of the walls,
• "Grouting" wide joints.

Acrylic-based products do not always have a water-repellent effect. When buying, you must definitely check whether the product is suitable for the bathroom.

Types of bathroom sealants

Sealants are gel-hardening airborne composites that retain elasticity. Initially, they were used as liquid pads, then as glue with waterproof properties. In everyday life, only one-component (ready-to-use) products are used, packaged in foil bags (“sausage”), polymer tubes, cartridges or aluminum tubes.

Using sealants in the bathroom solve several problems:

• waterproofing of walling - sealing cracks, crevices,
• rough finish - sealing of cracks between the door block and the wall,
• facing walls, floors - grouting tile joints (usually only in the corners and around the perimeter of the inspection hatches),
• installation of plumbing - sealing threads and sealing gaps between the side of the bathtub, sink and wall,
• interior decoration - gluing mirrors, hooks, decoration elements.

On the cladding, visible areas, a sealant is used that does not blacken under the influence of solar ultraviolet radiation and aggressive environments. The following classification of sealants by composition:

Polyurethane

The operational characteristics of the polyurethane sealant are as follows:

• elasticity 250%, that is, the frozen composition stretches 2.5 times without breaking,
• biostability - it is impossible to develop fungus, pathogenic bacteria, mold,
• chemical resistance - polyurethane adhesive can be used in slightly aggressive environments,
• high moisture resistance
• mechanical strength - polyurethane is not destroyed by vibration, it is difficult to scratch, the elasticity of the composition prevents cracking

Polyurethane glue is more expensive than acrylic, acid and neutral silicone.

Polyurethane would be a good choice for sealing the junction of the bathroom and the wall, if not for the only minus - it is difficult to form a seam and then remove the excess. It is used mainly as glue or for expansion joints.

MS polymer

When mixing silicone and polyurethane composition, you can save all their useful qualities, while eliminating the disadvantages. As was done by Japanese researchers, back in the 70s of the last century. MS-polymer sealant has the following characteristics:

• bonding of plastics - high adhesion with PVC, acrylic,
• UV resistance - the material will not turn yellow in the sun,
• shelf life - 2 years, operation - 10 years,
• staining the seam after drying or using a color composition.

The only drawback is the high cost of the product.

MS-Polymer Sealant is the best choice for sealing plumbing and wall joints. Such a sealant will not blacken, one minus is the price.

Application selection

In view of the foregoing, moisture-resistant quick-drying glue is used to solve the following problems:

The choice of a universal hybrid sealant (based on MS polymers) will allow performing any work in the bathroom at all stages of decoration and repair of the room.

Manufacturer selection

In the ranking of manufacturers of sanitary sealants, the positions are distributed as follows:

the leading brand is Penosil, owned by Estonian company Krimelte, adhesives based on polyurethane, silicone, acrylic,

Penosil the second place is occupied by the Belgian company Soudal, which produces a domestic line of products (acrylic, silicone) and professional mixtures based on polyurethane,

Soudal the third step belongs to the Ceresit brand of the German concern Henkel, which produces only acrylic and silicone sealant,

Ceresit in the assortment of the company Bostik (USA), in addition to acrylic and silicone products, there are MS and polyurethane sealants,

Bostic MS-sealant in Russia The Henkel Moment brand is a well-deserved success; the manufacturer's line includes bituminous, silicone, polyurethane, acrylic sealants.

Moment for bathrooms

Products of foreign brands are usually classified by type of basis. Adhesive compounds Moment are divided into areas of application - frost-resistant, high-temperature, for aquariums, mirrors, glass / windows, silicone joint restoration. All products are packaged in tubes for the gun, a large package of "sausage" is usually used only by European companies.

Thus, MS or acrylic sealant can be used to seal the joints between the side of the acrylic bath / sink / toilet and the wall. Transparent neutral silicone is ideal for gluing mirrors. Conventional silicone sealant (even sanitary) quickly blackens on contact with water.

Feature Comparison Chart

In order to compare the presented options, we propose to consider a brief table with the main characteristics.

Lists of the best

In addition to the previously indicated sealants, the following compositions are of special attention:

• Budget - CIKI FIX UNIVERSAL.
• Silicone - KRASS SILICONE UNIVERSAL.
• Acrylic - VGP ACRYLIC WHITE.
• Polyurethane - RABBERFLEX PRO PU 25.

Let us consider why they deserve high marks from experts.

Budget - CIKI FIX UNIVERSAL

One of the most budget options is considered to be CIKI FIX UNIVERSAL from a Turkish manufacturer. Even in the process of frequent use of the shower or bath, the composition remains elastic, does not crack or wash. The strength of the substance is its resistance to temperature changes, and the weak side is the absence of antifungal elements in the composition, so the bathroom will need to be regularly ventilated.

Price: from 95 to 120 p.

What to look for when choosing

To make the choice of sealant as successful as possible, pay attention to the following when purchasing:

1. High wet in the bathroom and shower creates excellent conditions for the development of mold, fungi and other biological formations. Composition, chosen by you, should become a reliable barrier for these microorganisms.
2. Most popular silicone composition - seams are perfectly closed by it, and also joints between a wall and bathroom equipment are condensed. In addition, such compounds are perfect in the process of updating old seams.
3. Pay attention to the bathroom: if you have it from metal, then in this case you need to choose a silicone sealant neutral. Acrylic sealant is suitable for acrylic baths, as it is closer to it in composition.
4. In addition to the main polymer, the composition also includes different additives - they are added either to improve technical characteristics, or to reduce the cost of goods. Therefore, if there are more than 10% of such additives, we advise you to refuse to buy - this sealant can be of dubious quality with a short service life.
5. If you are doing repairs in the country, where there is no heating in winter, then be sure to finish the bathroom frost resistant materials (including sealant).

Other species

In addition to the listed main sealants, the following are also available:

• silicone-acrylic - contain both polymers and combine their properties,
• aquarium - acidic silicone sealants without additional components, which are used for gluing glass parts, sealing showers, sealing aquariums.

As additives, sealants may contain:

• extenders (expanders) and fillers (quartz chips, chalk) - to fill wide joints,
• organic solvents
• dyes
• rubber - for plasticization instead of silicone,
• mineral oils.

Note: In a quality product should be no more than 10% of additional components. Otherwise, its insulating and adhesive properties are reduced.

Surface preparation

First of all, it is necessary to clean the surfaces from contaminants and residues of the old sealant. Then they should be degreased with acetone or alcohol and wiped dry. Deep seams should be flushed with hot air with a hairdryer. The surface should be perfectly clean and dry.

Masking tape ensures evenness of the seam and protects surfaces from contamination

Next, evenly stick masking tape on both sides along the seam. This will help protect the coatings from contamination and make a neat strip of sealant. This step is optional, but it will greatly facilitate subsequent processing.

Preparation tool

Sealants are available in tubes with a capacity of 80 to 400 ml. It is more convenient to use small bottles. The tube may be equipped with an applicator for application. If not, then you will need a battery or mechanical gun.

Cut off the tip of the bottle at an angle of 45 °. The cut location should be selected depending on how wide the seam is to be made. Then you need to put the tube in the gun.

Application

It is necessary to put the tip of the tube at the start point of the seam and gently squeeze the product, moving evenly along the line. It is important to “hammer” the sealant as deep as possible and pull the trigger of the gun all the time the same. Breaks should not be allowed along the seam, as water and dirt will get into them.

Using a special spatula to smooth sealant

For smoothness of the seam and removal of excess silicone or acrylic, you should draw along it with a finger soaked in soapy water or with an elastic spatula. In addition, you can install a special nozzle on the tube to align the sealant. It will allow you to simultaneously apply and smooth the product.

Final processing

In the end, it is necessary to remove the masking tape until the sealant has frozen. If at the same time the seam is damaged, it should be slightly moistened and leveled. If the product gets on the plumbing or tile, it can be removed with a wet rag. To combat persistent contamination, a solvent or refined gasoline is suitable.

After finishing work, the room needs to be ventilated. You can use the bathroom when the sealant is completely dry.

Features of some types of work

Recommendations regarding the implementation of certain types of work:

1. Filling the joint between the bath and the wall. Usually this seam is different in depth. Glue a narrow strip of foam under the bathtub shelf, and then process the joint. This will prevent the sealant from draining.
2. Fixing the corner (border) between the bathroom and the wall. It is necessary to prevent water from dripping onto the floor. The sealant can be used to further secure the corner. The product should not be applied to the curb, but to the bathroom shelf and wall. Then you need to put a corner and press it.
3. Tile sticking. Silicone should be applied only to the tiles with stripes around the perimeter and diagonally. Then the tile should be pressed to the prepared surface.
4. Tile grouting. During operation, use masking tape to protect the surface of the tile and quickly remove excess sealant with a spatula. It is important to fill the joints to the full depth.
5. The installation of the toilet. The sealant should be inserted as deep as possible into the gap between the floor and the plumbing fixture after installation.

Tip: To prevent the formation of mold in the bathroom, it is necessary to provide forced ventilation and heating of the room, since even on sanitary sealant it can still appear.

How to remove sealant?

Sealants have high adhesive properties, so it is difficult to remove them. Fresh silicone can be removed by cutting it with a thin knife. If the seam is wide enough to make an incision in one place, pry off the strip and pull it. It is more difficult to work with narrow seams. It is necessary to cut the sealant along the entire length, being careful not to damage the surface.

With durable materials, the remaining silicone can be removed with a metal washcloth. If the coating is subject to mechanical stress, it is better to use a damp, rough cloth.

You can get rid of the sealant, including the old one, using special solvents. Popular remedies are Silicone Remover, Sili-kill, Permaloid® 7010, Penta-840, CRC Gasket Remover. You need to use them according to the instructions, which say how to clean the sealant with this tool. As a rule, you need to apply a thick layer of cleaner on top of acrylic or silicone, wait a while and remove everything with a cloth.

Popular manufacturers

There are many sealants on the market today. To choose among them a high-quality waterproof drug, you should pay attention to the reputation of the producer. The following tools are popular:

• Ceresit CS 25 - acid silicone grout sealant with an increased proportion of antifungal components,
• “Moment Germent” - a series of sealants, which presents products based on acrylic and silicone, as well as options with fungicides,
• S 400 - acetate silicone sealant, characterized by high resistance to mold,
• Ciki-Fix is ​​a silicone sealant with excellent adhesive properties and good elasticity, but it does not contain fungicides,
• “Rubber Titanium” from the Professional series - a rubber-based polyurethane sealant that creates strong and flexible stripes, it is often used to correct silicone joints.

The right choice of sealant is an important aspect in the process of arranging a bathroom. Without reliable isolation of the joints between plumbing and surfaces in the room, it will be practically impossible to maintain cleanliness, and it will quickly become the habitat of molds harmful to health. Buying a sealant, you can not save, since the quality of the product is most often directly proportional to its price.

Selection Criteria for Bath Sealant

In the bathroom or shower, excellent conditions are created for the emergence and reproduction of microorganisms. High humidity and warm air contribute to the development of fungi, mold and other biological formations. Therefore, the composition should be a reliable barrier to microorganisms.

For many craftsmen, the most important property of a sealant is its simplicity and ease of application. Viscous gel-like materials that completely fill any voids deserve special praise.

A very unpleasant moment for owners of houses and apartments will be a violation of the integrity of the insulation (cracking, peeling). To restore the attractiveness of the cladding, it is necessary to clean the tile joints and apply a new composition. Therefore, the seam after drying should be elastic, durable and firmly hold on to the surface.

In country houses where there is no heating in the winter, the bathroom should be finished with frost-resistant materials. The sealant should have the same property.

Our review got the best sealants for the bath. When making the rating, the following criteria were taken into account:

Application area

The main disadvantage of acrylic sealants is the stiffness of the resulting seam. Even with small extensions, it bursts. That is, it is not worth using it to protect the junction of a steel or acrylic bathtub (shower tray) with a wall. Under load, they change their size and so that the seam does not collapse, it must be elastic.

They are great for filling voids and cracks in various building materials (brick, concrete, etc.), joining fixed or inactive joints (gaps between the door frame and a brick or concrete wall, sealing knocks in pipes, etc.). These compositions process the unprotected edges of the furniture, which is installed in the bathroom, suitable for filling the junction of the sink with the wall.

Acrylic sealants are good for filling cracks.

Another unpleasant moment: in a humid environment on the surface of a conventional acrylic sealant, fungi and bacteria multiply well. This disadvantage is eliminated by the presence of antiseptic additives, but for areas that are constantly in contact with water, acrylic sealants should not be used.

And one more thing: in the bathroom, acrylic quickly changes color - it begins to turn yellow. Therefore, you should not use white. Better color (there are such) or transparent. On them, color changes are not so visible.

When choosing, it is worth remembering that acrylic sealants can be waterproof and not. The acrylic sealant for the bathroom should be waterproof. Even in areas where water cannot directly contact it, but because of the increased humidity, it can absorb moisture from the air.

Acrylic Sealant Brands

There are quite a few good brands. Only for the bathroom, it is imperative to watch that the composition is moisture resistant.

• Bison Acrylic. There are several different compositions: Superfast with drying in 15-30 minutes, Universal - can be used to seal wood.
• Bosny ACRYLIC SEALANT,
• Boxer
• Dap Alex Plus. This is an acrylic-latex composition with greater elasticity and additives from fungi.
• KIM TEC Silacryl 121. Polyacrylate, moisture-resistant and elastic sealant. It can be used in areas of prolonged contact with water.
• Penosil. For filling joints and cracks that are not in direct contact with water.

There are many more other brands and manufacturers. Many acrylic sealants have special additives that change their properties. If you are comfortable with their harmlessness, you can find a composition even for direct contact with water.

Properties and scope

Properties and scope of silicone sealants:

• They have good adhesive ability. Can be used to seal the joints of stone and plastic window sills, when installing a sink and other appliances in the countertop.
• It is used for sealing joints of glass, non-porous building materials (metal, plastic, glass, wood, ceramics), plasterboard adjoining to the ceiling, drainpipes.

Silicone sealant for the bathroom is a good choice

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

Brands and prices

Silicone sealant for a bathtub is popular today and in any store there is a quite decent assortment.

As you can see, there is a very wide variation in prices. Expensive sealants (Ravak, Ottoseal. Lugato) - made in Germany, Denmark, Czech Republic. According to reviews, they have excellent quality - they have been used for several years without changes, the fungus does not breed on them. They are presented in the widest gamut of colors.

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

Polyurethane

Polyurethane sealants are good for outdoor use. They are not afraid of changes in temperature and humidity, they tolerate ultraviolet well. They can work on open or closed, but not heated balconies and loggias. Also, their properties are in demand in wet rooms - bathroom, toilet and kitchen. The main advantage is that they have a very good adhesive ability, for which they also call adhesive sealant.

Polyurethane compounds are good for everyone, but have poor adhesion to plastics

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 which is better. The advantage of silicones is that they “stick” well even to plastics, and polyurethane compounds that they have no odors.

This type of sealing compounds refers more to general construction. Many compositions are ideal for sealing interpanel seams in multi-storey buildings and for other similar work. Sealant for the bathroom - one of the options for use.

Sealants with MS polymers

A recently introduced type of sealant, which, thanks to its excellent properties, is rapidly gaining popularity. They combine the qualities of silicones and polyurethanes, reliably protecting against leakage, forming elastic and reliable joints.

VS polymers - excellent qualities for the bathroom and other wet areas

Manufacturers and prices

Almost every major manufacturer has MS sealants, and they also have various additives that add special characteristics, so you can choose exactly according to the situation and for a particular type of work.

Despite the fact that this type of sealant has appeared recently, the assortment 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, tolerance to prolonged direct contact with water, and resistance to the growth of fungi and bacteria. Therefore, this type of sealant is used to seal the junction of the bathroom or shower with the wall. In the case of a shower cabin, it is also good because it does not slip during vertical application.

Another positive point - most of the compositions have a pasty consistency that lies flat, does not bubble. After application, prior to initial hardening (film formation), the applied sealant can easily be leveled, giving it the desired shape.

Which bath sealant is better

It is necessary to choose the type of sealant for specific tasks. Then you can choose the optimal properties. For example, to seal the junction of a bathtub or shower with a wall, the best choice is a sealant based on MS polymer. Not bad - silicone and polyurethane. But they must have antibacterial additives.

Neutral silicone sealant is excellent for gluing mirrors. Slices of countertops, edges and sections of furniture that are installed in the bathroom or in the kitchen are coated with any silicone (acidic).

If you need to stick a fallen tile in the bathroom, a polyurethane compound or with MS polymers is suitable. Due to the high adhesive ability, they immediately fix the product in place. Since the compositions do not shrink when dried, there is also no risk of damaging the tiles.

The main problem is blackening from the fungus. Solved by the presence of antibacterial additives

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

When decorating a bathroom in a wooden house, the walls are usually sheathed with moisture-resistant hypo-cardboard. But since the house constantly “plays” in height, there remains a gap between the ceiling and the GCR - to compensate for these changes. To prevent moisture from entering it, it must be filled with something, but so that the seam remains elastic. Silicone and MS polymer compositions can also be used for these purposes.

To solve the problem of blackening of the seams, you need to choose compositions with antibacterial additives. There are also special sanitary sealants. They are so named precisely because of the presence of additives against fungi and mold. Sealants for aquariums are also suitable for these purposes. They have excellent adhesion to most materials and never blacken.

As you can see, for each type of work the best sealant for the bathroom is its own, but the most universal is based on MS polymers.
