Two-component agent for priming the edges of expansion joints before filling with Fugenspachtel joint compound. The product increases the adhesion of the expansion joint to the substrate. It is used as a preparation improving the adhesion of joint masses to the substrate.

Properties

• binary
• quick drying
• colorless
• solvent based
• for priming the edge in expansion joints
• used before filling expansion joints with Koester Fugenspachtel FS-H or FS-V in order to improve adhesion to the substrate
• The material binds fine dust particles and is resistant to saponification
• thanks to its low viscosity, the product penetrates the substrate, strengthening and stabilizing it
