Coo-Var Acrylic Primer Sealer Undercoat
This water-based primer and sealer is specifically formulated to prepare surfaces for topcoating. It works effectively on both plaster and wood, making it an essential product for professionals looking for a reliable base layer. It provides excellent adhesion, ensuring that the topcoat adheres properly, and offers a smooth, matt finish. With its low odour and non-flammable nature, it is perfect for use in areas with restricted ventilation.
Surface Preparation
Before applying this primer and sealer, ensure that all surfaces are clean, dry, and free from contaminants. For best results on new wood, it is recommended to sand the surface to create an adequate key. Existing painted surfaces should be degreased and sanded, with all loose material removed, to ensure proper adhesion. Do not use the product on surfaces that are not prepared as advised, as it may affect the performance of the final coating.
Application and Drying
This product can be applied using a brush, and it dries quickly, typically touch-dry within two hours at 20°C. However, it is essential to follow the recommended drying times between coats to ensure optimal performance. The full hardness of the coating is achieved in 5-7 days, but you can recoat after 6 hours.
Do not apply the product if the temperature falls below 7°C as it may hinder the drying process and affect the final outcome. Additionally, always provide adequate ventilation during application and drying, particularly in enclosed spaces.
Limitations and Recommendations
This product should not be applied when temperatures are below 7°C. It is designed for plaster and wood surfaces and should not be used on metal or unprepared surfaces. Always ensure surfaces are clean and properly prepared before application. For optimal performance, use suitable topcoats after applying this primer and sealer. If other products are needed for specific projects, consider consulting our range of specialised coatings for additional protection and enhanced results.
