works as directed

By 

from Nevada

Comments about this product:

I;ve used Flex Seal and Flex shot for as long as they've been on the market. I fix dripper hoses, cracks in my siding, plug holes and it works just fine. It actually saves me money not having to replace hoses, boards or whatever needed to be fixed. It also lasts a very long time, actually after 5 yrs. on a hose, it's still holding just fine.

Cracked toilet water tank.

By 

from Fairfax, VA

Verified Buyer

Comments about this product:

My toilet's water tank had a 5 inch crack. I used Flex Seal on the inside and a little on the outside. It did the job. No more leaks! Saved over $150 for a new replacement toilet.

Wouldl not buy again for the size that we received.

By 

from minneapolis Ms

Pros

  • It did seal what I wanted to seal

Cons

  • misleading AD on the amount a pint not gallon

Best Uses

    Comments about this product:

    Would not buy again for the price I paid for the amount I received. The can size on TV is not the same size as I received. Other people have had the same complaint. I cannot find a price for a gallon of the product. That would be helpful, although it would probably be overpriced anyway

    Size is a scam

    By 

    from NY

    Verified Buyer

    Pros

      Cons

      • Advertising Is Misleading
      • Covers Maybe 4 Sf Not 18
      • Not Enough To Do Much
      • Pricing Is Bad
      • You Only Get 16 Oz

      Best Uses

      • Cracks Not Patching

      Comments about this product:

      Ad shows a jug and/or gallon. What you're buying is a PINT for almost $30! And it only covers maybe 4 sf, not the 18 sf shown on the can. Probably good for a crack, but not as an overall sealant.

          The ad on TV made the can look bigger. Had I known it was ONLY a pint can I wouldn't have bought it.

            It worked wonders on a leaky Roof that has lasted for a couple years. And it saved me alot of money. The only complaint that I have is that they need bigger containers to sell.
