1.5 thick waterproof layer = = 1.5mm thick waterproof layer polymer waterproofing membrane thickness. Generally, the construction thickness of polymer cement-based waterproof coating film is not more than 1mm, and the total thickness is not more than 2mm.
Polymer cement-based waterproof coating (also known as polymer waterproof slurry and polymer waterproof glue) is a kind of high-performance acrylic polymer cement-based waterproof material. It is emulsified by adding other additives into acrylic polymer with acid and alkali resistance, aging resistance and high elasticity. Waterproof coatings suitable for different parts can be prepared by adding a certain proportion of cement.
How to use polymer cement-based waterproof coating
Clean the construction surface to ensure it is smooth, free of impurities and cracks, and smooth the sharp parts. According to the instructions of the coating, cement and liquid materials are added in proportion and fully stirred. Spray the construction surface wet, and then stick glass fiber cloth at the joint to strengthen it. Apply 2 layers of waterproof coating, and do mortar protection layer after it is completely dried.
Waterproof coating is made of polyurethane as the main raw material and a proper amount of coal tar. The price is not high, but it is difficult to remove coal tar because of its toxicity, and it could not be used as early as 2000.
