Don’t let the decoration leave hidden dangers. Suggestions for the selection of waterproof coatings in bathrooms (pictures from the Internet)
Introduction of toilet waterproof coating
Liquid waterproof coatings mainly refer to polyurethane waterproof coatings, which are divided into tar type and non-tar type. Non-tar-based coatings are the most commonly used waterproofing materials on the market today. It uses non-tar substances as curing agents, such as curing agents composed of asphalt, additives and fillers. 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. At the same time, during construction, it is necessary to properly grasp the thickness of each brushing. 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.
Bathroom waterproof coating selection skills
(1) According to the local maximum temperature and minimum temperature, flexibly select waterproof coatings suitable for heat resistance or low temperature flexibility. In high temperature areas, waterproof coatings with high heat resistance should be selected to prevent flow; in severe cold areas, waterproof coatings with good low temperature flexibility should be selected to avoid cold and brittle.
(2) According to the degree of foundation deformation, structural form, local annual temperature difference, daily temperature difference and vibration factors, waterproof coatings with suitable tensile properties should be selected. For building roofs with large structural deformation, waterproof coatings with high elongation should be selected to adapt to deformation, such as Leibangshi’s flexible JS waterproof coating.
(3) According to the exposure degree of the roof waterproof coating film, the waterproof coating should be suitable for ultraviolet resistance and heat aging retention rate. For exposed roofs, UV-resistant waterproof coatings should be used to increase the service life.
(4) When the drainage slope of the roof is greater than 25%, it is not suitable to use a waterproof coating that takes too long to dry and form a film.
Must be used in combination of two materials of Group A and B:
When consumers purchase non-tar-type waterproof coatings, they must purchase two groups together and use them in combination. At present, non-tar-type waterproof coatings occupy most of the market share, and well-known domestic brands have exclusive stores, which are easy for consumers to buy.
Professionals remind: when consumers buy non-tar waterproof coatings, don’t forget to buy a certain amount. Due to different manufacturers, the internal ingredients are not necessarily the same, the amount of diluent to buy depends on each brand. Most diluents are in bulk, and the quality is difficult to control. Regular manufacturers of non-tar waterproof coatings are sold in a set of three barrels. The thinner manufacturer has already prepared it, and there are many different grades of products to choose from. Consumers can choose according to their own economic strength and decoration grade. .
