3M High Strength Crack Repair's precision tip applies the fiber reinforced compound directly into surface cracks in both interior and exterior fills. Ideal for drywall, ceilings, stucco and concrete fractures (and more!). TIPS FOR SUCCESS: Puncture the seal on inside to ensure a large hole for the product to flow. When near end of crack, hit the release (or turn the plunger rod) to release pressure. When done, put a nail or screw in the caulk tip and wrap with masking or duct tape
