Product Overview

Properties

Water-based liquid concentrate for construction and DIY use. It serves as a bonding agent between new and old surfaces, a primer before plastering, screeding, or tiling, a keying agent on smooth surfaces, and a barrier between incompatible surfaces. When added to cement, screeds, or grouts, it improves flexibility, adhesion, and water repellency.
