*Temporary on non-porous surfaces.
Montana Chalk Sprays feature the look and feel of a rough chalk effect. These chalk-based pigment sprays are ideal for temporary outdoor markings as well as for indoor studio artwork. This is a great medium for events, advertisements, marketing campaigns and outdoor activities. Studio artists will find new possibilities with these colourful deep-matte high-covering chalk pigments. They can be applied on various surfaces such as sidewalks, walls, cardboard and canvas. The chalk markings will last from several weeks to several months, depending on climate and weather conditions. The more porous the surface, the longer pigments will remain. The chalk colour pigments will wash away faster on non-porous surfaces like glass or metal, but some pigments may remain on porous surfaces. Contents are non-hazardous to plants, and therefore ideally suited for use in the garden and landscaping. Artwork can be finished and sealed with spray varnish to create long lasting permanent effects.
