Abstract
A peelable thermoplastic coating (36) applied to one face of an architectural piece (14) such as brick, concrete paver and veneer, and tile. A spray applicator (10) automatically applies the coating substantially edge-to-edge of the face of the piece. A method for grouting the architectural pieces includes applying the grout over the coated faces of pieces arranged in spaced-apart patterns and spreading the grout into the spaces, and peeling the coating from the pieces. In another embodiment, the coated faces are adhered to a form liner, grout or cement is applied to the backs of the pieces and between them, and the form liner and coatings are stripped from the pieces.
Claims30
A thermoplastic coating composition suitable for coating the upper surface of an architectural piece, which comprises a cellulosic thermoplastic resin and a plasticizer and optionally minor portions of a stabilizer and a release agent in such proportions that the resulting mixture when mixed and melted and applied to the upper surface of an architectural piece and cooled provides a coating which has a softening point above about 170° F. (77° C.), has a low friction surface, is waterproof, has a low tack and is easily peelable from the architectural piece.
An architectural piece having a thermoplastic coating substantially completely covering an upper surface thereof, all other surfaces of the architectural piece being substantially free of the thermoplastic coating, the thermoplastic coating being peelable intact from the architectural piece.
A method for grouting coated architectural pieces, each piece comprising a thermoplastic coating substantially covering one face of the piece, the method comprising:
- a. fixing the architectural pieces in a predetermined pattern having spaces between the pieces,
- b. applying grout or an adhering material over the coated pieces without regard for the coated pieces,
- c. spreading the grout into the spaces between the pieces, and
- d. removing the thermoplastic coating intact from the architectural pieces.
A method for making a concrete wall having brick or stone veneer pieces which comprises:
- a. providing an embossed liner having a desired pattern to hold the veneer pieces in place in the base of a concrete wall form;
- b. spraying an adhesive onto the embossed liner;
- c. placing coated veneer pieces onto the liner with the coated side of the veneer pieces contacting the adhesive on the liner;
- d. pouring concrete into the concrete wall form;
- e. allowing the concrete to cure forming a concrete wall;
- f. removing the form from the concrete wall;
- and
- g. removing the liner along with the coating from the veneer pieces resulting in a concrete wall containing veneer pieces.
A coating composition suitable for coating the upper surface of an architectural piece, which comprises major portions of cellulose acetate butyrate and a plasticizer and minor portions of epoxidized soy bean oil in such proportions that the resulting mixture when mixed and melted and applied to the upper surface of an architectural piece and cooled provides a coating which has a softening point above about 170° F., a low friction surface, is waterproof, has a low tack and is peelable from the architectural piece.
