Select K Rend preparation materials for approved render carrier boards, with attention to the board type, supporting structure and joint detailing. Rendering a board façade requires a compatible reinforced system that accounts for movement within the construction.
This range includes HP12 and HPX base coats alongside alkali-resistant mesh. Suitability depends on the particular board and the manufacturer-approved build-up, including fixings, reinforcement and decorative finish. Confirm these details with K Rend and the board manufacturer before installation, and use the specified treatment around joints, openings and changes in background.
