Muro Quartz Render Primer

Product Description
Plaster/quartz primer is a quartz-containing adhesion promoter, primarily used on uneven substrates for leveling and thick-layer pre-treatment in interior and exterior applications. It is also suitable as a preparation layer for subsequent coatings such as rubbed plasters, mineral finishing plasters, and similar materials. Plaster primer is vapor-permeable and weather-resistant in accordance with VOB, Part C, DIN 18363 (painting and coating works).

Application
Used to improve adhesion for finishing coats made of mineral dispersion, silicate, and silicone plasters. Plaster/quartz primer reduces and equalizes the absorbency of the substrate and enhances bonding with corresponding finishing plasters.

Substrate
The substrate must be clean, dry, grease-free, and load-bearing. Old coatings that do not adhere properly must be removed. The surface must be fully cured and dried. Sandy or dusty substrates should be pre-treated with suitable primers. Suitable substrates include gypsum, lime, and cement-based plasters without coatings, provided they are clean and dry.

Application Instructions
Stir plaster/quartz primer thoroughly before application (undiluted). For plasterboard, wood fiber boards, and chipboard, apply only after prior priming. Application is done using a brush or lambskin roller. Allow a drying time of at least 12 hours. Clean tools immediately with water after use.

Storage
Store plaster/quartz primer in tightly closed containers in a cool, frost-free place. Keep opened containers tightly sealed and use promptly. Do not exceed a storage period of 12 months.
