Promac Rubber Duck Damp Guard is a single-component acrylic primer and moisture barrier developed to protect walls and surfaces affected by damp conditions. It forms a dense, water-resistant film that bonds effectively to both damp and dry surfaces, making it suitable for use on plaster, cementitious, and fibre cement substrates. By sealing the surface and preventing moisture penetration, it helps reduce paint failure such as peeling and bubbling. Available in 5L and 20L pack sizes, this product is suitable for both residential and commercial damp-proofing applications.
