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.

The product was unusable when container was first opened. It was already cured and hard.

I like this product and have used it before. However, this very expensive tub was half dried out already upon arrival.

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.

So far, it's working as expected. Roof leak has stopped.

The label showed it was 22 years old,the top of the paste was hard. The center was covered by a paper patch,after I removed there was a 1” opening for me to pull out most of the paste.

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.

The product does the job as advertised.
