Patent number: 6231949Abstract: An improved surface repair assembly for repairing a damaged portion of an exposed surface of is provided. The surface repair assembly includes a surface repair patch and a curable surface repair compound. The surface repair patch comprises a sheet which is formed from a plastically deformable inelastic polymeric material. The sheet has a plurality of openings which extend from the first side to the second side of the sheet. The openings are arranged about the sheet so that a network of strips of polymeric material is formed. Each of the strips is capable of being plastically deformed in any direction so that the sheet may be shaped to correspond to the contour of the surface being repaired. The sheet supports, positions, and reinforces the curable repair compound on the surface before the repair compound is cured. In one version of the invention, the second side of the repair patch includes an adhesive for affixing the patch to the surface to be repaired.Type: GrantFiled: February 12, 1998Date of Patent: May 15, 2001Assignee: Pro Patch Systems, Inc.Inventor: Dennis Hoffmann, Sr.
