Bathroom renovation involves sealing cracks in the walls and joints between tiles.

It is a special waterproof compound that prevents moisture from entering cracks and joints. In order for the sealant to perform its functions successfully, you need to choose the best option. The highest quality products are described in the rating.

Types of sealants

By its composition, any sealant is a mixture of filler and hardener. All products are divided into types depending on the type of polymer in the composition:

1. Silicone. Sealants of this group are considered the most demanded. They combine well with any finishing materials and sanitary ware, are highly resistant to moisture and do not deteriorate under the influence of high temperatures and steam. The material itself is elastic and practically does not shrink after application.
2. Acrylic. Acrylic resin bath sealants adhere well to concrete, brick and plaster and are therefore commonly used to seal cracks in walls. They are also resistant to ultraviolet light and high temperatures, but at the same time they have an affordable cost.
3. Polyurethane. The compositions of this group are used for capital repairs of a bathroom and for plumbing. These sealants are highly resistant to chemicals and mechanical damage.

In a separate group, it is customary to allocate a sanitary sealant with antifungal impregnation or an antiseptic in the composition. They perform not only a waterproof function, but also prevent the spread of mold in the bathroom.
