Surface Preparation & Concrete Bonding Agents
Bonding agents, concrete key coats, and sealers engineered to create optimal bonding surfaces for plastering and adhesives.
Engineering Overview & Performance Capabilities
The durability of any coating, plaster, or tile adhesive is strictly governed by the quality of substrate preparation. CRO CHEM bonding agents and concrete mechanical key coats bond fresh cementitious overlays to smooth precast panels, cast-in-place columns, and old concrete with unbreakable chemical tenacity.
Technical System Methodology
Smooth fair-faced concrete, vibrating formworks, and oily release agents create hostile surfaces that reject standard mortars. Our synthetic polymers and SBR latex bond bridges convert low-suction concrete into rough, high-friction receptive anchor keys.
