(1) Acrylic, 3 kg/m2 per square meter

(2) Polyurethane: the dosage is about 2 kg / m2

(3) Polymer polymer: the dosage is about 3 kg / m2

(4) Flexible cement mortar: the dosage is about 3 kg / m2

It is convenient to construct, environmentally friendly and non-toxic. It is also a good choice. Waterproof mortar coating has high film strength and good bonding with the base layer. It can be directly pasted with tiles, which is economical and practical. However, because it is a rigid waterproof material, it is not suitable for the renovation of new houses that may have settlement.
