This product is simple, easy to use. Erase-A-Hole™ is superior to any product like it on the market today because its patented blend of stable ingredients makes it guaranteed shelf stable for two years. Erase-A-Hole has been featured on HGTV, Living In Style, and more. In two easy steps, you can fill holes and cracks in drywall, wood, and plaster. All you do is rub the special applicator in a circular motion until the hole is filled, then wipe with excess off. Once it is dry you can paint. It does not shrink like other products on the market and doesn’t dry out!
