A method for making a decorative pattern on a surface, said method comprising the steps of:

• etching said surface with a solution containing approximately five to ten parts water to one part muriatic acid;
• brushing said surface with a stiff bristle broom to promote dispersion and interaction between said solution and said surface;
• before said solution dries, pressure cleaning said surface with water at a pressure of about 3,000 psi (about 200 kg/cm.sup.2) to remove said solution;
• placing a template made of a flexible plastic and having a pattern formed of a plurality of openings therein onto said surface, said template having a thickness;
• applying a layer of a composition to said surface, said composition including water, an acrylic latex polymer, cement, sand, and an oxide powder color additive, said composition applied to said openings of said template to a thickness of no more than said thickness of said template;
• removing said template from said surface before said composition cures, said template leaving lines in said layer;
• as said layer begins to cure, lightly wiping said layer with a damp sponge;
• cleaning composition from said lines;
• scoring said layer to simulate old brick using a textured roller;
