PRIMER FOR CONCRETE & STONE

Description

Primer for Concrete & Stone is a colourless, solvent-based, liquid primer composed of polyurethane resins, which has been specially designed for use as primer in order to ensure and enhance a perfect adhesion between the substrate and the polyurethane sealants such as Floor Joint Sealant (Art. No. 892351200), as well as with the self-levelling sealants, Flexible Expansion Joint Sealant (Art. No. 1892350209).

Application Fields

•    Priming for polyurethane-based joint sealants subjected to both important stresses and movements or cyclical conditions.
•    Treatment for porous surfaces of joints to reduce surface porosity and avoid pinholing and bubbling in polyurethane based joint sealants.

Advantages

•    Excellent adhesion to concrete and metal surfaces.
•    Good coverage and high performance: works to tensile or shear straight, or both.
