Sealing the bath with the wall: a description of the technology, features and reviews

Sealing the bath with the wall is to treat the joint between them to prevent water from entering the floor and improving the appearance of the bathroom. The concept of "sealing" implies a complete impermeability of the object for gas or liquid. To achieve this result, special materials with the appropriate properties will be required.

Methods of sealing joints in the bathroom

Ways of sealing the bath with a wall:

• Treatment with silicone sealant (silicone) ;
• Blowing with mounting foam;
• Sealing with cement mortar;
• Mounting angle;
• Sealing with curb tape;
• Combination of several methods (for example, a joint treated with silicone, you can top off with a curb tape).

Material selection

The main requirement for the materials used in the bathroom is thermal and water resistance. For sealants and other insulating materials, the additional requirement is complete watertightness. Sealing the joints of the bath with the wall is intended not only to technically decorate the room, but also to prevent the appearance of fungal and mold damage on the surface of the walls and floor, to prevent the development of other harmful bacteria.

Therefore, when choosing materials, it is necessary to give preference to those that have antibacterial and antifungal components in their composition.

Silicone sealant

How to seal the bath with a wall With silicone sealant? Tools that you need to work:

• Alcohol or solvent;
• Scissors or sharp knife;
• Tube with silicone sealant (transparent or for the color of the walls in the bathroom);
• Mounting (construction) gun;
• Plastic or ceramic plinth.

Sealing the bath with a silicone wall involves the following procedure:

• Thoroughly clean the joint and the surrounding surfaces from dirt, debris, etc.
• Degrease joint with solvent or alcohol. Dry it.
• Cut the tip on the tube with the sealant. In this case it should be taken into account that the sharper the angle of the cut, the thinner the line will be.
• Apply sealant with a mounting gun in the form of a continuous line as neat as possible.
• Dampen the applied silicone with soapy water and straighten the line with your finger.
• If desired, a plastic or ceramic curb can be glued over the sealant.

Mounting foam

Sealing a bath with a wall using a foam is one of the easiest ways to solve a problem. Tools that you need to work:

• Alcohol or solvent;
• Construction knife ;
• Gloves;
• Balloon with mounting foam;
• Material for finishing.

Procedure:

• Thoroughly clean the joint and the surrounding surfaces from dirt, debris, etc.
• Degrease joint with solvent or alcohol. Dry it.
• Wear gloves.
• Shake the can with mounting foam and apply it evenly to the joint, avoiding hitting the walls and the surface of the bath. When applying, it is necessary to take into account the fact that after drying the volume of foam increases significantly.
• Dry for an hour.
• Remove the excess dried foam with a construction knife.
• Depending on the type of decoration of the bathroom walls, it is possible to seal the seam and then cover with a suitable color or glue a border of tile, plastic, etc.

Solution

How is the bath with the wall sealed with cement mortar? Materials and tools for the performance of work:

• Rags;
• Plaster blade;
• Solution tank;
• Sand quarry;
• If you only have river sand at hand, you will need a plasticizer (professional or its replacement: lime, clay or laundry detergent);
• Cement M400 or M500;
• spray;
• water;
• Material for finishing.

Procedure:

• Thoroughly clean the joint and the surrounding surfaces from dirt, debris, etc.
• Prepare a medium-density solution.
• Lay the joint with a rag soaked in a liquid solution. This will help to prevent the composition from getting on the floor.
• Moisten the surface of the walls and bath at the junction.
• Carefully apply the solution, taking care that the seam is not too wide.
• After drying, depending on the type of finishing the walls of the bathroom, you can fill the seam and then cover with a suitable color or paste a border of tile, plastic, etc.

Preparation of the solution:

• If there is a river, and not a quarry sand, first you need to add a plasticizer, otherwise the solution will turn out to be not sufficiently dense, which means that the seam will be unstable as a result. Instead of a professional plasticizer, lime, clay or laundry detergent can be used. The mixing ratio should be: 4: 0.8 sand / lime; 4: 0.5 sand / clay; 4: 0.2 sand / washing powder.
• Add one part of the cement to the sand or its mixture with the plasticizer in the proportion: 4: 1 for M400 and 5: 1 for M500.
• Stir the mixture thoroughly with a spatula.
• Gradually add water until a medium density solution is obtained.

Corner

Corner for sealing the bath with the wall is another fairly simple and reliable way to solve the problem of sealing the joint. Other of its names - plinth plastic, border of PVC for the bath. For tile is more suitable border of ceramics. Materials and tools for corner mounting:

• Glue transparent quick-drying (for tile glue for tiles);
• Alcohol or solvent;
• Plastic or ceramic plinth (border) for the bath;
• Construction knife;
• Painting Scotch tape;
• Mounting gun;
• Transparent silicone sealant.

On sale there are skirting boards with already applied adhesive layer. It is better not to use them, since this glue does not have moisture resistance. If you mistakenly purchased this corner, then the layer of glue from it must be carefully cleaned. To do this, you will need a knife and a solvent. Stronger compounds are not recommended because they can seriously damage the surface of the baseboard.

Procedure:

• Thoroughly clean the joint and the surrounding surfaces from dirt, debris, etc.
• Degrease joint with solvent or alcohol. Dry it.
• Cut the curb with a construction knife on the strips of the desired length at an angle of 45 degrees.
• Attach the curb pieces to the joint.
• Glue along each part along the edges of the paint tape to prevent the glue from getting on the surface of the walls and bath.
• Remove the border.
• Apply glue to the joint.
• Again, attach and tightly glue the pieces of the curb.
• Allow the glue to dry, then remove the paint tape.
• Place the edge of the curb to the wall with a thin layer of transparent silicone sealant.

Curb Ribbon

For those who do not have experience in performing construction work, the problem will be even such a simple task as sealing the bath with a wall. Fixing the joint with self-adhesive border ribbon is the simplest and least time consuming way to solve this problem. On the back of this material there is a glue layer based on butanol. Kinds of a border ribbon: angular and figured. It is sold in the form of rolls. Figured tape differs from the corner by the presence of an additional sector (centered) without glue. The kit usually includes an applicator, corners, sometimes a construction knife. When choosing a bath tape, it is recommended to give preference to products with antifungal components.

When buying self-adhesive edge curbs, you need to pay attention to the fact that this product has a limited shelf life. It refers to the glue layer. On sale basically there is a tape of white color, but it is possible if necessary to pick up a border of the necessary shade in the companies which work under the order. The length of the standard roll is 3.5 m. It is tied to the perimeter of a bath of the usual size, but just in case it is better to measure the actual length of the joint. The width of the tape can also be different: the narrower it is, the better. It is recommended to use a wide tape only in the case when the width of the joint itself demands this.

Materials and tools for work:

• Alcohol or solvent;
• Curbstones;
• Building scotch;
• applicator;
• Construction knife;
• Sanitary sealant for the bath.

Procedure:

• Thoroughly clean the joint and the surrounding surfaces from dirt, debris, etc.
• Degrease joint with solvent or alcohol. Dry it.
• Cut the ribbon with a construction knife into pieces of the desired length with a margin of 2-3 cm on each side.
• At the junction of the cutting of the tape and the corner, leave the upper part straight, and cut the bottom at an angle of 45 degrees.
• Attach the curb pieces to the joint.
• Glue along each piece along the edges of the paint tape to mark the place of adherence of the tape to the wall and bath and ensure its even location.
• Remove the border.
• Bend the tape along the fold line and heat with hot air, this will improve the adhesion of the adhesive layer to the walls and bath surfaces.
• Starting from the corner, glue each piece on the notch made with an adhesive tape. Carefully remove the protective layer on the back of the tape 15 cm and, smoothing, glue it, tightly pressing the applicator.
• Secure the corners with a sanitary sealant.

Features of working with acrylic coatings

Sealing an acrylic bath with a wall Requires consideration of some features of working with similar coatings.

• Do not use any glue, as there is a great risk to spoil the surface of the bath.
• You need to choose glue compounds for plastic and vinyl.
• Do not use concentrated solvents.

The cost of sealing the bath and reviews

If there is no desire or time to seal the joint by itself, you can invite a specialist plumbing. The list of services it provides includes sealing the bath with the wall. The price of work, depending on the method chosen by the customer, will be from 350 to 3000 rubles. This does not usually include the cost of materials.

Feedback on some methods of sealing:

• Some people did not like the result of independent work. It turned out that without skill it is difficult to level the sealant in one motion, and if it is interrupted, then flaws are visible.
• Very neatly obtained joint of the bath with a tile with a plastic corner. Apply the silicone sealant so that it completely fills the space under the corner, and then the plinth is attached to it. We get a silicone seam, completely enclosed by a corner.
