There are still many things to pay attention to during the construction process of polymer modified asphalt waterproof coating. Only by mastering the details can there be no problems in later use. Below, the polymer modified asphalt waterproof coating manufacturer will take you to understand the construction matters of polymer modified asphalt waterproof coating.

Before using high polymer modified asphalt waterproof coating for construction, we need to prepare tools such as mixing buckets, sprayers, or brushes. Then, we need to perform base treatment on the ground to ensure that there is no loose slurry, peeling, hollowing, or serious cracks on the surface. The surface flatness should meet the requirements of bridge specifications, and the bridge deck should be free of dust, floating ash, impurities, oil stains, etc. Before laying the waterproof layer, we can use air compressors, water purifiers, degreasers, etc. to clean the surface. If there are hard impurities such as concrete and mortar, they should be polished clean.

Waterproof layer construction steps: Before painting, the bucket of paint should be stirred evenly. When painting on a large area, use a small brush to brush the leakage area twice, and the internal corners three times with waterproof paint. Then, brush the large area once and dry it before applying the third layer. The coating dosage is generally 0.5mm-0.7mm thick, with a dosage of about 0.7-1.0kg. It should be noted that the construction temperature is 0-35 ℃, and it is not suitable for rainy and winter construction.
