## Description

Product description Stops leaks fast. Starts out as a thick liquid and dries to a super strong, flexible, watertight, rubberized coating. Seeps into cracks and holes. Blocks out air, water, and moisture for a superior seal, virtually anywhere. Prevents rust and corrosion. Extends the life of patio furniture, pool pumps, RV and shed roofs, and more. Stands up to extreme weather changes. Expands, contracts, flexes and stretches. Resists rain, snow, sun, and hail. Exceptional adhesion. Works on all types of surfaces, even challenging ones, like metal and glass. UV and chemical resistant. Use indoors and outdoors for basement waterproofing, foundation fixes, roof repairs, and more. DIRECTIONS Fully clean and dry the surface for best results. Etch the surface to help with adhesion if needed. For the best application, use a standard disposable paint roller or paint brush. Apply several even, thin coats and wait 24 - 48 hours for each layer to fully dry before adding the next. Always place the lid back on the container after each use. If drying occurs, remove any skin before using product.

Review: Amazing Product Seals Like Crazy - I had a problem with water seeping from my deck into the bedroom below. Every time a storm approached, I had to lay down plastic sheeting and hope for the best. Once I discovered Flex Seal, however, I stopped worrying. I reapply a coat every couple of years, and the sealant holds up perfectly. I even used it to fill in some wooden planks experiencing dry rot, and it seems to have halted the decay of the planks. This is just in my experience; I can't attest to this being an approved use of the prouct.
Review: Stopped foundation wall leak—amazing product that really works well. - December 2021 update: Our state had one of the wettest year’s on record, and Flex Seal continues to do its job to an extent that we did not have so much as one drop of water leaking through the coating. It remains solid but flexible, and there are no signs of cracking or peeling. We have a 7’ long foundation crack. 38 year’s ago we sealed the crack with Drylock FastPlug. Water leaked through. Then we used Drylock cement paint. It worked for a few years, then water seeped through. A few weeks ago, we put three coats of gray colored Flex Seal (cones in a quart paint can) across the surface of the crack. Big rain came a few days later, and there was not even a drop of moisture to be found. Thus is amazing stuff. If this didn’t work, the only way to fix this leak would be to excavate the foundation wall from the outside. Word of mouth says that this product is great to stop foundation wall leaks. Note: this stuff is like thickness of honey. It spreads best with a paint roller. The gray color blends very well with the surrounding foundation wall. But it also comes in other colors. Always fill large cracks with Drylock Hydraulic cement and let dry before using Flex Seal Make sure you clean the wall to ensure good adhesion

### ⭐⭐⭐⭐⭐ LOVE THIS STUFF
*by P***F on October 27, 2025*

I love flexseal!! Some people don't, and they are wrong. I held a concrete pool edge together for years with this stuff. Concrete was coming off in chunks, I flexsealed those babies back in place, coated the area, and it was fine for years. This can was used to seal a messed-up ditch dug across my asphalt driveway. "How do you mess up a ditch??" you ask. Well, my guy managed. I had to have another guy jackhammer part of it back out, then I coated the whole thing with flexseal. I expect it to last years, and if it starts to come apart, I'll put more on.
