Gritty Slate Paste
Gritty Slate Paste is a water-based acrylic that creates a sandpaper finish on all primed and porous surfaces. Apply with a brush or palette knife. After drying the surface creates a smooth grey glossy textured finish which is waterproof and can be painted over. Drying and curing can take 30mins to 12 hours depending on the thickness of the layer. Natural drying at room temperature is recommended. Rinse all tools in application with warm water. Keep out of direct sunlight. Non-Toxic. Not suitable for children under 14 years.
