Four principles of household waterproof coatings to buy home waterproof materials do not bother, family waterproof experts suggest that home waterproof coatings can follow four principles:
(1) The owner flexibly selects the waterproof coating suitable for heat resistance or low temperature flexibility according to the highest temperature and the lowest temperature in the past years. 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, the structural form, the local annual temperature difference, the daily temperature difference and the vibration factor, the owner should select the waterproof coating that is suitable for the tensile properties. 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 owner should choose a waterproof coating that is compatible with UV and heat aging retention. 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.
