A elastic membrane includes a pair of parallel strips of a lamination consisting of a non-stretchable plastic film coated on both sides with a pressure sensitive adhesive, resulting in a pair of pressure sensitive adhesive bands bonded to a rear side of the membrane along each lengthwise edge of the elastic membrane, leaving an uncoated midsection of elastic membrane. The adhesive bands are covered with a release liner, with longitudinal slits cut through it to allow selective removal from one adhesive band or the other or a portion of one adhesive band as desired during installation. One side of the elastic membrane is attached to the wall surface adjacent to a crack to be covered and repaired, and the midsection of the elastic membrane is stretched across the crack and the other elastic band is pressed against the wall. The elastic membrane can be treated with spackle or dry wall mud to blend into the surrounding wall and can be painted.
