The bathroom is the place that deals with the most water. How to stay away from the trouble of water seepage is to choose suitable waterproof materials. How to pay attention to the selection of waterproof coatings when decorating? The editor will tell you how to choose waterproof materials for bathroom decoration.
At present, there are two main types of home improvement waterproof materials on the market: one is liquid waterproof coatings, polyurethane waterproof coatings and polymer composite waterproof coatings; the other is powdery waterproof plugging materials, such as waterproof rubber powder and plugging materials. Leaking and so on.
Liquid waterproof coatings mainly refer to polyurethane waterproof coatings, which are divided into tar type and non-tar type. Among them, non-tar type coatings are the most commonly used waterproof materials in the market. This kind of waterproof coating is divided into two groups, group A is the curing agent, and group B is the main component of the material. This material has stable quality, less pollution, good aging resistance, good adhesion and water increase. Non-tar waterproof coatings are mainly used for waterproofing of toilet and kitchen floors.
Mix Group A and Group B evenly with a thinner before use in a certain proportion, and then paint on the treated base. Therefore, consumers must buy two groups together when purchasing non-tar-type waterproof coatings. During construction, they must properly grasp the thickness of each application. Generally, more than two millimeters can meet the waterproof requirements. After testing the water to ensure that there is no leakage, a protective layer of cement mortar must be made on the waterproof layer to prevent sharp objects from piercing the waterproof membrane and causing water leakage during subsequent construction.
Tips: When consumers buy non-tar-type waterproof coatings, they must buy enough, because different manufacturers have different internal components, and the amount of thinner is also different.
In addition, the walls should also be waterproofed. In order to achieve a better waterproof effect, the wall of the general bathroom should also be waterproofed with a height of about 30cm to prevent the accumulated water from seeping through the wall. On the wall adjacent to the bathtub, the height of the waterproof treatment should also be higher than the upper edge of the bathtub. Only in this way can we ensure that nothing will go wrong.
