Rules for working with sealant. How to properly apply sealant in the bathroom?

Sealants play a special role in the bathroom - they are used to seal joints between tiles, as well as joints between tiles and a bathtub or shower. With their help, it is possible to achieve a more aesthetic appearance and give the renovation completeness. An additional function is protection against condensation, splashes and high humidity, which contribute to the development of pathogenic fungi and bacteria.

We present to your attention a rating of the best sealants. When choosing, the following characteristics and indicators were taken into account:

• setting speed of the composition;
• ease of removal after drying;
• brand value and prevalence;
• mildew resistance;
• consistency;
• degree of adhesion - the quality of adhesion with other materials.

Tips for use

When sealing a bathroom, you need to place a backing between the plumbing fixtures and the wall so that the polymer composition does not flow down

The optimal consistency of compounds for plumbing work is gel-like, viscous, filling all voids. For small jobs, experts advise stocking up on several small packages rather than one large one.

Depending on the initial conditions and sealing purposes when applying a polymer product, it is recommended:

1. For wide joints use acrylic compounds, and for narrow joints use silicone mixtures
2. Do not use silicone acid sealants on glass, marble, metal, granite or cement surfaces.
3. When filling deep seams between the wall and the plumbing, use a foam backing under the bathroom shelf to prevent the product from dripping
4. To fix the corner of the bathroom, also use sealant as glue

Prevention

It is important not only to know which sealant for the kitchen is better, but also to understand what to do after cleaning the surface so that the process does not repeat itself. Prevention is the key to protecting the health of people living in the house. Taking preventative measures is always easier than dealing with emerging mold.

Provide good ventilation to the room; be sure to ventilate the room periodically. Otherwise, you won’t be able to get rid of high humidity in the bathroom and kitchen. Problems with plumbing, such as water leaks, need to be resolved in a timely manner.

If the ceiling and walls freeze, then insulation is required; this is an ideal environment for the formation of moldy areas. To prevent mold from spreading from neighbors, cracks that have cracks are also sealed using an anti-fungal sealant. These simple methods will help prevent mold from forming again, keeping people safe.

Provide good ventilation to the room; be sure to ventilate the room periodically.

It is necessary to choose the best sealant taking into account the working conditions and the degree of the problem. There are many options for removing mold; everyone decides for themselves which one is best for them. It is important to find all areas with mold, otherwise the spread of fungus will not stop. And in the future they resort to preventive measures that will help avoid recurrence.

Preparatory work

The more thoroughly the seam is prepared, the longer the sealant will last without darkening or leaking water. First of all, the gap must be thoroughly cleaned of dirt, debris and dust. Then the surface is allowed to dry (deep cracks are dried with a construction hairdryer).

If there are pieces of old sealing compound left in the crack, they must be completely removed. The old sealant is probably affected by mold. The fungus will quickly spread to the new composition. Acrylic and silicone are washed off with solvents (Penta-840, Silicone Remover and others), polyurethane is removed mechanically.

Remove the greasy film from the surface of the bathtub and the wall with alcohol or another solvent (acetone, nail polish remover, etc.). Then, if necessary, lay a cord into the gap, and cover the edges of the seam with masking tape.
