[ITEM 2] QUESTION: Bathroom renovation: how to choose moisture-resistant materials and sealants?

The choice of moisture-resistant materials and sealants for a bathroom renovation determines the durability of the entire renovation and the protection of the premises from mold and mildew. Practice shows that for the successful completion of this stage, it is best to create a detailed checklist that will include a list of necessary purchases, accurate area measurements, and a list of approvals from the management company if a redevelopment is planned. Maintaining such a document and recording all expenses helps avoid construction defects, alterations due to inappropriate products, and unnecessary overspending of the family budget.

When choosing materials for walls and floors in the bathroom, the key criterion is their absolute resistance to constant moisture exposure and temperature changes. For wall decoration, it is best to use ceramic tiles, large-format porcelain stoneware, or moisture-resistant panels, avoiding ordinary paper wallpaper or drywall without special impregnation. For the flooring, choose tiles with a high slip resistance coefficient to minimize the risk of injury on a wet floor after taking a shower.

Special attention should be paid to the choice of sealants and mounting foams, as they protect joints and seams from water penetration. Budget universal silicone compounds, which quickly turn yellow and become covered with black fungus, are completely unsuitable for the bathroom. It is necessary to buy specialized sanitary sealants with powerful fungicidal and antiseptic additives that prevent the development of microorganisms in conditions of constant dampness. Different types of sealants are required for different surfaces: acrylics are suitable for low-mobility joints, and silicones are for movable joints between the bathtub and the wall.

To properly apply these materials and avoid leaks in the future, follow this sequence of actions. First, thoroughly clean and degrease all joints before applying the sealant. Then use masking tape to form a neat and even seam. After applying the composition, smooth it with a special spatula or a finger moistened with soapy water and let it dry completely according to the manufacturer's instructions. Such an attentive approach to details guarantees the tightness and aesthetic appearance of your bathroom for many years.
