DampFix Pure Acrylic Damp Barrier is a coating designed for interior and exterior walls to prevent rising and penetrating damp. It adheres well to damp or dry substrates, covers damp stains, and prevents them from reappearing. Suitable for various surfaces, it offers a micro-porous formula to control water migration and prevent efflorescence, has excellent alkali resistance, and provides a smooth matt finish for easy topcoating. It's low-VOC, quick-drying, and available in white for optimal coverage. It requires 2 coats for general application, with a coverage rate of 7 – 7.5 m²/litre per coat, and a third coat may be needed for very porous or extremely damp surfaces.
