Polymer Waterproof and Crack-Resistant Mortar
The product is available in two types (waterproofing and anti-cracking), offering high flexibility, high bonding strength, superior weather resistance, excellent waterproof and anti-crack performance, environmental friendliness, and ease of use.
Information
-
Net Weight: 25KG, 40KG
-
Model: Thin-layer, Thick-layer
Features
-
Low shrinkage: Effectively reduces cracks and fissures.
