ABSTRACT:
An improved multi-layer repair patch is provided. The patch has general repair applications including uses on drywall and automobile bodies. The preferred embodiment includes a three layer patch including an inner mesh, a middle reinforcing sheet and an outer mesh. No glue or adhesive needs to be applied to the middle sheet. The inner surface of the inner mesh carries an adhesive coating and the inner surface of the outer mesh carries an adhesive coating. The inner mesh is attached to the surface under repair and the outer mesh secures the middle sheet between the two mesh structures. In the preferred embodiment, the middle sheet is perforated and the perforated middle sheet, in combination with the inner and outer mesh structures enables liquified bonding material to migrate through the patch during the repair process.
