Flex Paste, 6 lb Tub, White, Waterproof Paintable Putty, Spackle Sealant, Fill Gaps Cracks Holes - Block Out Water and Air - UV Resistant - Walls, Drywall, EPDM, Concrete, Roof, RV Repairs

My neighbor over waters and the extra water flooded under a wooden tool shed and the termites took advantage. He didn't want to stop the overwatering and didn't want to put plastic up against his block wall. We dug down two feet and painted our side of the wall. No water getting through at all. The new toolshed should hold up better.

Ordered two 6 # tubs. 65 + % of the tubs were hardened when they arrived and would not spread. Use a small can about a month ago and it worked very well. I suggest not ordering the larger size until the company can fix the problem. My second comment after contacting the seller. Within 48 hours I had an answer which corrected the problem , a very welcome solution. They are great to do business with.

I bought the 6 lb paste but 2 lb of it dried up in the bucket and couldn't be used when I opened the tub. Overall, 1/3 of it is wasted. Obviously, the container design is faulty and unable to keep the paste from drying. When I told Flex Seal of the issue, here is what they said. "Thank you for reaching out. I am so sorry for that experience. Since you purchased through Amazon the best thing to do is to use the Amazon messaging system to contact the seller. We hope you have a great day!" Thank you for reaching out. I am so sorry for that experience. Since you purchased through Amazon the best thing to do is to use the Amazon messaging system to contact the seller. We hope you have a great day! I replied ti Flex Seal that I didn't have a great day after reading your response. This is sarcastic! It is easy to pass on the blame to the reseller/distributor when the real issue is your product.

Very good product will get again.

The tub is smaller than you think, but contains enough for most jobs. The inner core was still soft and could be used, but the majority had hardened to a clay before arrival. 70% + useless on arrival. It's bright white. Paint-able after drying, but will stick to EVERYTHING. Use a disposable spreader or you'll never use it again.

My husband was very pleased with this product for filling in the cracks in our blacktop driveway. So far it is holding up great.

The product is difficult to spread, came with a solidified ring in the tub that was unusable (about 15% of the overall container). It did work for the job but there are MUCH cheaper alternatives that will do a better job.

Used it to patch concrete foundation that broke out. It stuck on very well. Will have to see if it works and for how long. Concrete patch only lasted about a year then started cracking. Awful expensive for what you get it better last longer.
