1. Product characteristics:
1. Good crack resistance, good elasticity, can independently bear the role of resisting base cracks, and can significantly improve the decorative effect after elastic coating application.
2. It has strong adhesion to the base surface and elastic coating, and can effectively solve the peeling phenomenon of elastic coating.
3. Can be used with various coatings.
4. Easy to construct and polish, resistant to water and alkali.
2. Scope of application:
It is suitable for scraping and leveling the cement mortar, concrete, lime mortar, cement fiber and other base layers of building exterior walls before coating. The exterior walls of buildings, when matched with elastic coatings, can resist micro-cracks caused by various reasons, and jointly solve common minor cracks and other non-structural cracks.
