When in use, it is firmly combined with the base surface to achieve waterproof effect. The product has outstanding flexibility and can resist slight vibration and displacement to a certain extent. It is a new type of green environmental protection product promoted by the Ministry of Construction. Its products have been manufactured with high quality, and can be directly constructed on wet base surface, which is suitable for water seepage parts around corners and pipelines. Moreover, the adhesive force is strong, and the active components in the coating can penetrate into the capillary holes and micro-cracks on the cement base surface and produce chemical reactions, which are integrated with the matrix to form a crystalline dense waterproof layer.
