All surfaces must be cured, clean, sound, dry and free of all dirt, dust, efflorescence, wax, oil, grease, chalk and any other contamination that would interfere with new coating adhesion. New plaster must cure for a minimum of 30 days at 72°F (22°C) prior to coating application. Sand smooth and dust. Fill cracks with spackling compound, allow to dry and sand smooth. Remove sanding dust. Performance will be directly related to the degree of surface preparation.
The products above are commonly recommended for plaster. Other Diamond Vogel products, including our Pinnacle Protective Coatings, may be better suited for your project. Please contact your Diamond Vogel representative for personalized service.
