Judging whether the waterproof quality of the paint room (painting room decoration effect diagram) is passed, the quality of the waterproof paint between the paints will be checked first. Currently, there are two types of home waterproof materials on the market, one is liquid waterproof paint, polyurethane Waterproof coatings and polymer composite waterproof coatings; the other is powdery waterproof plugging materials, such as waterproof rubber powder and plugging spirits. How do consumers choose the right waterproof material for the paint to ensure that the waterproof layer in the house is safe?
Introduction of waterproof coating between coatings
Liquid waterproof coating mainly refers to polyurethane waterproof coating, tar type and non-tar type. Non-tar type coatings are the most commonly used waterproofing materials on the market. It uses a non-tar type material as a curing agent, such as a curing agent composed of asphalt, additives and fillers. Such waterproof coatings are divided into two groups: Group A is a curing agent, and Group B is the main component of the material. The material has stable quality, low pollution, good aging resistance, good adhesion and water absorption.
Non-tar type waterproof coating is mainly used for waterproofing the floor between the paint room and the kitchen (kitchen decoration renderings). The group A and the group B can be uniformly mixed with the diluent before use, and then the coating can be applied on the treated substrate. At the same time, it is necessary to moderately grasp the thickness of each painting during construction, generally more than two millimeters can meet the requirements of waterproofing. After the test water is ensured that it does not leak, the cement mortar protective layer must be made on the waterproof layer to prevent the sharp object from piercing the waterproof film to form water leakage in the subsequent construction.
Waterproof coating selection skills between coatings
(1) According to the local maximum temperature and minimum temperature, flexible choice of waterproof coating suitable for heat resistance or low temperature flexibility. In high temperature areas, waterproof coatings with high heat resistance should be selected to prevent runny; in cold regions, low temperature flexible waterproof coatings should be selected to avoid cold and brittle.
(2) According to the degree of deformation of the foundation, structural form, local annual temperature difference, daily temperature difference and vibration factor, waterproof coatings with appropriate tensile properties should be selected. For building roofs with large structural deformation, waterproof coatings with large 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 with the resistance to UV and heat aging should be selected. For exposed roofing, UV-resistant waterproof coatings should be used to increase the service life.
(4) When the roof drainage slope is greater than 25%, it is not advisable to use a waterproof coating with a long drying time.
It is necessary to use two materials in combination of A and B: When consumers purchase non-tar type waterproof coating, they must be purchased together and mixed. At present, non-tar-type waterproof coatings occupy a large share of the market, and domestic famous brands have specialty stores, which are easy for consumers to buy.
When consumers buy non-tar type 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 thinner should be determined according to each brand. Most of the thinner is in bulk and the quality is difficult to control. The non-tar type waterproof coatings of regular manufacturers are sold in a set of three barrels. The thinner manufacturers have already been equipped, and there are many different grades of products to choose from. Consumers can choose according to their own economic strength and decoration grade. .
