MURRAMI SAND BASE is a specialist reinforcing primer with added quartz that provides excellent adhesion for structural, mineral, and decorative plasters. Its fine quartz sand particles create a rough, non-slip surface that facilitates the bonding of subsequent layers and reduces the risk of detachment. The product is designed for use on a variety of substrates, including concrete, cement-lime, gypsum, and drywall. It works perfectly as a bonding primer for mineral, acrylic, and silicone plasters, as well as other coatings requiring a stable, well-prepared surface. MURRAMI SAND BASE can be applied with a roller or brush, creating an evenly rough surface that improves adhesion and reduces material consumption. Its hydrophobic properties make it suitable for both indoor and exterior use, protecting surfaces from moisture and weather conditions. This product is indispensable for those seeking an effective solution to improve the durability and quality of the final decorative effect.
