Viponds Self-Adhesive Prep Coat: The use of popular acrylic wall paints as the base coat to apply self-adhesive digital prints onto walls has created some issues. The main problem has been loss of adhesion of the print after a few days. Self-Adhesive Prep Coat has been especially formulated to enhance the adhesion of self-adhesive digital prints onto internal and external surfaces. It is a low VOC water-based paint that dries quickly with minimal odour. Self-Adhesive Prep Coat is an all-in- one primer and topcoat. It has been developed to have superior adhesion to a variety of substrates, whilst drying to a hard finish that is resistant to scratching and marring. Self-Adhesive Prep Coat provides an ideal surface for applying permanent and removable self-adhesive digital prints made from vinyl, polyester or canvas. Suitable for interior and exterior use. Self-Adhesive Prep Coat is classified as non-hazardous and is low in odour and is ideal to be used in "on site" applications.
