More information
A water-based paint used as a primer coat after applying a skim coat (such as Walltex), for renewing previously painted surfaces without the need to remove the existing coating, and as an undercoat for decorative paints.
It offers excellent resistance to cracking and peeling, even under harsh weather conditions. Its high hiding power reduces the number of coats required, while its water-based formulation allows for easy cleaning with water during application.
