Not just for holes and cracks!
Would RecommendI used this product to fill many cracks and holes and works great. Now, I found another use which turned out perfect. I installed a flat screen on brick wall above the fireplace. Also installed an outlet close to the brick wall. The problem was the wire going behind the flat screen. Fast setting, made small batches to hold cord to the power strip in the mortar joint then filled in. Also painted the end of the cord same color as wall to blend in. Problem solved.
Works FAST!
Would RecommendSeals and stops water leaks in basements. Work QUICK - this stuff sets up fast!
It sets REALLY fast. Only mix a little at a time.
Would RecommendEasy way to fill in concrete where we added a new conduit. We were able to mix a small amount at a time. It sets fast which was perfect for our circumstance.
It ain't cheap
Would RecommendMy installer was impressed with the product quality.
Works on sewer pipes
Would RecommendI've have used this on rusted cast iron sewer pipes and fittings which stops the leaks. Just mix small batches as other reviewers have mentioned that it dries extremely fast.
