- From a piece of scrap material, cut a matching repair piece that will cover the damaged area. Use a straightedge or square. To hide the seam, make a cut in a grout line or where two different colors meet.
- Place repair piece over damaged area and fasten with double-faced tape. Be sure the pattern is aligned correctly.
- With the point of a knife, score around the repair piece deep enough to identify the outline of the damaged area to be removed.
- Remove the repair piece from the double-faced tape.
- Holding the knife perpendicular, cut along the score lines on the damaged piece.
- Cut through the middle of the damaged material and peel away from the substrate, being careful not to damage the edges.
- Clean residue of adhesive and backing from the substrate, apply adhesive to the back of the repair piece and put in place. Roll with a hand roller and clean off any adhesive that might be on the surface.
- Apply seam treatment as recommended for the product being repaired.
- Protect repaired area until seam treatments have dried.
