An ornamental coating and process for applying the coating to a substrate includes mixing a first batch of liquid mortar composed of sand, cement and an aqueous solution of acrylic resin, and trowelling or spraying a first layer of the liquid mortar onto the substrate and allowing the liquid mortar to cure. A second batch of liquid mortar is mixed which is the same as the first except that it contains a color pigment contrasting with the color of the first batch. A template defining a pattern of grout lines is placed over the cured first batch and the second batch of liquid mortar is trowelled or sprayed over the first batch and the template as a second layer and allowed to cure only to the extent that the second layer is firm, but not hard. The template is then removed, removing any part of the second layer immediately above the template thus exposing lines of the cured first batch which then appear as grout lines between areas of colored mortar which appear as bricks, flagstone or tiles etc. When the second batch has completely cured, two layers of concrete sealer are applied. The same coating may be applied over a properly supported wood substrate with proper preparation. An expanded galvanized metal lath is secured to the wood. This is then covered with a cementitious base coat which is allowed to substantially cure. The described ornamental coating then is applied over the base coat.
A process of covering a substrate with a decorative surface comprising:
A process for coating a substrate with a decorative surface comprising priming said surface with a dilute aqueous solution of adhesive resin, mixing a first batch of liquid mortar consisting of a mixture of cement, sand and an aqueous solution of adhesive resin and applying a first layer of said liquid mortar to said surface while said priming solution is wet;
A cementitious ornamental surface placed over a substrate comprising a primer coat of a dilute aqueous solution of adhesive resin, a first mortar layer formed of a mixture of cement, sand, and an aqueous solution of adhesive resin applied over said primer coat while said coat is still wet and allowed to cure;
