Abstract:

A method of placing color indicia or tints on a porous surface includes the steps of forming a base layer on a surface, such as a floor, by applying a liquid layer of an unpigmented metal interlock acrylic finish to the surface, and allowing the base layer to dry. A pigmented layer of liquid metal interlock acrylic finish containing an acrylic polymer emulsion and pigment substance is then applied over the base layer in the form of an indicia, such as a decoration, advertisement, or pattern. After the pigmented layer has dried, a protective layer of liquid metal interlock acrylic finish is then applied over the pigmented layer and allowed to dry to protect the design, and the protective layer can be buffed to a shine. The method can be used to quickly and easily apply directional aids, advertisements, tints, or other colored indicia to a floor. Both the pigmented and unpigmented layers are readily removable with common detergents such as ammonia.
