Method for making a decorative cementitous pattern on a surface
First Claim
1. 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/cm2) 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;
removing accumulated dust and grit from said layer; and
applying a sealer to said layer.

Abstract
A surface coating composition comprising generally cement, sand, a polymer binder, and water, and a method for applying the composition to a surface. The composition is used to apply an ornamental surface coating onto a pre-existing cementitious surface, or a surface to which a cementitious base layer has been applied. The surface is cleaned with a muriatic acid solution. A flexible plastic template is laid on the surface to define the desired pattern and a thin layer of the composition is applied. The template is removed after the composition is applied. After the composition starts to cure, the surface is wiped with a damp sponge to round off corners and open up surface pores. The surface is sealed after curing. Texturizing rollers may be used to provide a more realistic finish. The coating is tough and durable, and can withstand up to approximately 6,000 psi (about 400 kg/cm2) pressure.
