Do NOT order more cans than you will need for a project- as these are not eligible for returns

Ordered two cans to complete a project (sealing the bottom and sides of a water feature in backyard). Product works very well, but I only needed to use one can to complete the project. Unfortunately the second can was not eligible for return. 😒

did the job, easy to use

Problem of electrical cord passing down through a backyard fountain. Someone had tried to seal it with RTV, which left it leaking and a surface difficult to seal to. I cleaned surfaces with white vinegar (4 percent acetic acid), then muriatic acid (15 percent HCl), and then rinsed and dried. Brushed acids on with old tooth brush. Secured the cord to prevent movement and applied two generous layers to this sealant two days apart, extending them out past the old seal attempt a couple of inches. Applied it with a popcicle stick and cleaned up my hands immediately with soap and water. No leak, no mess, no trouble. Doesn't matter whether it sealed to the old RTV or not as I can see it bonded well to the electrical cord and to the fountain surface. I bought 2 pounds and probably used about one or two ounces, but it was well worth the cost. I like things that work the first time with no hassle, especially when fixing someone else's screwup.

Works well, stores terrible

Used to coat Texas-Sun exposed top edge of an Intex pool. Application went well and, so far, so good. Be prepared to throw away your brush and, please know, the product in the can will not stay a liquid, even with a can top perfectly installed and...sealed with flex seal. Buy only what you need

Sealed my bird bath

I used this to seal my cement bird bath. Works great- no more leaks and it keeps it from getting rust/mildew stains. It was hard to clean out my brushes though, so maybe just buy a cheap paint brush you can throw away when you’re done.

It works well at first, but the rubber is rubbing off of our shower floor. We used it to seal a hole that was leaking from the shower floor to the basement. We followed all instructions precisely and even let it dry longer than the instructions designated, but after a month, it is starting to wear.

Beats expectations

This is first time with this particular Flex formula. The results are amazing as it leaves a flexible rubber coating. I have an older favorite cracked sprinkler..water sprayed everywhere except where it should. This product filled in all those plastic cracks and it now works like new. Did not have to toss and help fill up landfill. Dogs have 10 year old 6ft rigid plastic pool..also ready for dump. Was able to fill all cracks and they are out playing in it.Edit: I Realize I used this product for minor repairs just to practice and try out, but have no doubt all the experienced DIY users commenting on their great experiences using for bigger repairs are correct.

Coated my workbench for electronics repair work

I coated my whole workbench in my garage with the stuff and they turned out amazing. It was about 45 degrees, so I put a little space heater on it and it dried in a couple hours.
