ABSTRACT:
A method is provided for masking a crack in a drywall or plaster surface of a dwelling, comprising the steps of die cutting a repair patch from a heat-shrinkable plastic film of a defined size presenting a surface area adapted to be placed in covering relation over the crack and bounded about its periphery by surrounding edges. The patch is prepared with an adhesive confined to the surrounding edges only and is placed over the crack making an initial attachment to the drywall and heat is applied to the patch, to cause a contraction in size of the patch while exerting a pressure normal in size in the patch.
