What is the difference between anti-crack mortar and plastering mortar?

Anti-crack mortar and plastering mortar are important components of the anti-crack protective layer in the exterior wall insulation system. They all play a role in protecting the insulation layer, preventing cracking, waterproofing and impact resistance.
1. Standard
1. Anti-crack mortar. This material is an ideal anti-cracking material for covering and plastering materials such as polystyrene particles and vitrified microspheres. The quality of the anti-cracking mortar directly affects the use effect and service life of the entire insulation system. Use this mortar The covered thermal insulation system effectively solves the problems of thermal insulation, heat insulation, wind pressure resistance, fire prevention, freeze-thaw resistance, hydrophobicity, weather resistance, flame retardant, breathability, cracking and other problems of exterior wall insulation. It also has good flexibility and product stickiness. It has the advantages of high knot strength, good waterproof and crack resistance, easy operation and easy control, which can ensure long-term performance, environmental protection and safety.
2. Plaster the surface with mortar. This material is mainly constructed on various wall insulation surface layers to form an excellent crack-resistant and anti-seepage surface layer, which is conducive to protecting the comprehensive performance of the insulation base layer, improving the affinity of the insulation surface layer interface, and providing excellent performance for the construction of subsequent facing materials. Interface base layer, this product is a special plaster anti-crack mortar for vitrified microsphere thermal insulation fireproof mortar surface layer. It is also suitable for EPS\XPS thermal insulation surface layer and various thermal insulation mortar surface layers for surface anti-crack treatment.
2. Testing data
1. The anti-crack mortar is made thicker, while the plastering mortar is thin, and the plastering mortar also has board breaking rate requirements.
2. The cost of plastering mortar is much higher than that of anti-crack mortar. The deformation of the insulation board is relatively large, so the flexibility of plastering mortar is much greater than that of anti-crack mortar, otherwise it will easily crack. </p
