    Q:Can flex seal be used on sun room vinyl flooring?
    by|Jun 14, 2024
    1 Answer
    Answer This Question

    A:  Hey there! Although Flex Seal Liquid will likely adhere to the surface, we do not recommend using our products for any underfoot repairs. Being such an effective sealant, water beads on the surface and poses a hazard. If you have any other questions, feel free to send us an email at humans@flexsealproducts.com. We're always here to help!

          Do not buy
          I bought 4 cans of this expensive stuff and it didn’t work on my roof. It actually peeled right off after drying.

            poor adhesive
            The product is a nice rubber and seem to spread nicely with a roller. I was not happy with how easy it came off just by hand. I applied it to a concrete wall inside i had roughed up then washed off with a wet reg.

                Fixed my balcony leak for under $300 vs a repair of $30,000.
                I would have given this product a five rating, but I have not seen how long it lasts and it is a little harder to work with than applying paint or varnish. I used about three gallons to heavily seal a stone floor on a balcony that was not properly installed. The subcontractor did not put a moisture barrier beneath the stone and mortar. The result was water finding its way into the wall and staining the wall board in our entryway. I poured and brushed to achieve about an eight of an inch thickness. This completely solved the problem of the leaking. Before doing this I received a quote to fix the problem that was over $30,000, so this solution made much more sense to me.

                Worked great on balcony tiles
                I made the mistake of installing Mexican pavers on my balcony which are very porous and absorb water. I tried different sealers but because water pooled up on the pavers it caused water to leak through the tiles and drip underneath the balcony. So I tried Flex Seal clear liquid and am quite impressed with the results. First the pavers have a nice new glossy look. Second, water can no longer penetrate them, it beads on the surface.

                  False Advertising; Does not work.
                  Absolutely does not work. As I write this my roof leaks Fifteen Gallons of water per room through the flex seal this rain storm alone based on Home Depot 5 gallon containers that I have through out my house. Water simply leaks through the Flex Seal as though it were not even their. Looks good; but it leaks terribly. Spent thousands of dollars. Needs a class action law suit. Be Warned!

                    Log house
                    Used the clear liquid glue to seal my log house inside & out. I best thing I could've done. Regular stain sealants weren't working & costing me thousands of dollars. This stuff has done the job.

                    Over-Rated products
                    My grandparents bought over 30 gallons for their basement that continously floods. We applied the paint to both the walls and floors following every direction on the can. We spent 900+ dollars repairing every room in the basement. One year later all the repairs we made were damaged and the basement was flooded as if we hadn't just fixed the leaks in the foundation. I recommend you don't waste your money or time with this product.

                      Flex seal on the back of a rug?
                      I put it on the back of a rug that had lost its backing but I wanted to save it as I loved the rug it worked beautifully.
