3M™ High Strength Large Hole Repair is designed to tackle holes between three and five inches in both interior and exterior spaces. This strong spackle is fiber reinforced and dries five times faster than other 3M™ spackle compounds. This product works best with the 3M™High Strength Large Hole Repair Plate, by flexing and adhering behind the wall for a professional-looking finish (without having to hire a pro!)
