Abatron KRACK Crack Repair Kit

Make invisible, permanent repairs to cracked walls and ceilings in under an hour. No sanding required. Once the second coat dries, it is ready to paint. No primer needed. The specially formulated acrylic emulsion is used with a polyester mesh to bridge over cracks. It retains its flexibility as it dries, without shrinking. This allows the repair to move as the wall moves, leaving a seamless repair that will not reopen like other fillers or putties.
