Cornerstone Promix Medium Topcoat is a dry ready mixed render and plaster designed for finish render coats within an appropriate render system. Available in the colour tan, which provides an attractive light tan finish with a medium texture when floated with a plastic or wooden float and a smoother yet moderately textured finish when sponged.
Engineered with precision utilising 100% pure natural hydraulic lime, natural sands, and conservation-appropriate additives to create a high-performance render and plaster that withstands high-traffic areas or outdoor elements. Enhanced plasticity supports a decreased likelihood of slump and improved adhesion. Further, a longer open time makes this render undemanding to apply, level, and finish. Available as standard with Saint-Astier® NHL2. Other binders and mix ratios are available upon request.
Well-suited as part for those looking for a natural and traditional aesthetic or a medium textured finish.
