POLYMiX Thin Render Premium is a high quality polymer modified water-resistant cement-based thin render specially formulated for direct application onto concrete surfaces for all patching and repairing and surface levelling works. It is suitable for both internal and external applications and specially formulated as a superior substitution to site mix cement sand plaster for medium build application by manual method. The product eliminates the need for key coats and addition of bonding agent normally required for traditional site mix and standard render. The grain size is also specially formulated to create a medium light sanded uniform texture when sponged.
