Customers are mixed about the seal. Some mention it does a good job at sealing, and works well to seal out moisture. However, others say that it doesn't seal as advertised, won't always seal holes over a 1/16 of an inch, and is not a fix-all sealer. It is easy to use, but it does take several coats to accomplish seal.

71 customers mention37 positive34 negative

Customers are mixed about the value of the paint. Some mention it's good for the price, and cheaper than the nationally advertised spray sealer. They say it can save you time and money in the proper conditions. However, others say that it'll waste your money and leave a whole can full of waste.

"...The price is cheaper and the performance was better and the only reason that I did not give it 5 Stars was due to a really strong odor..." Read more

"...Yes. does not disappear and can leave a little sheen. Very expensive especially with the spray...." Read more

"This was a great value. Got this on sale for less than half the price of flex seal. Does the job but does have a strong odor until it cures...." Read more

43 customers mention16 positive27 negative

Customers are mixed about the appearance of the paint. Some mention it looks good after application, making the chair look like new. They also appreciate the clear finish and smooth/satin finish. However, others say that it comes out runny and drips all over everything. They say it's too watery and does not give a good coat. Additionally, customers also mention that the product clogs after using about only about a 1/4 can.

"This clogged after using about only about a 1/4 can. Was spraying all at once on seams on a pontoon boat, so using the whole can...." Read more

"...It's not the prettiest, but it beats a duct tape X." Read more

82 customers mention15 positive67 negative

Customers have issues with the ease of spraying the paint. They mention that it sprayed in globs, did not go on smoothly, and unevenly. Some say that the product would not spray at all and that the nozzle was missing. They also mention that the spray can doesn't go far and that it has a low viscosity when first sparked, so it will run and drip.

"...There was NO NOZZLE; I had no way to spray the sealant...." Read more

"...Yes. does not disappear and can leave a little sheen. Very expensive especially with the spray...." Read more

"...Worked very well. Has low viscosity when first sprayed, so it will run and drip if you are not careful in applying it to an overhead surface...." Read more

"...Having holes in the sealant and paint will allow moisture to enter the holes, defeating the purpose." Read more

Excellent for water protection but must recognize the limitations
4 Stars
Excellent for water protection but must recognize the limitations
Have been using this product for complete water proofing of concrete and masonry for at last 3 years. Must use enough .. really does the water proofing and sealing. Yes. does not disappear and can leave a little sheen. Very expensive especially with the spray. Not cheaper with the larger cans and spreading with brush or roller. For my purpose, I want complete water proofing of some concrete and masonry. Good also as added insurance when used over concrete patch.Photo of concrete walkway with and without flexible rubber coating spray

I used this product to temporarily plug a few leaks in my old gutters.
This product didn't work! It did not seal any leaks. I continued to get leaks when it rained.
I decided to tra a second application - and upon opening the cap, the NOZZLE FLIPPED OFF!
Very DISAPPOINTED with this product.

1.0 out of 5 stars The can arrived without a seal and there was no nozzle to spray out the sealant. Cheap broken stuff.
Reviewed in the United States on March 6, 2023
I ordered this item and it came at under $10. Got it the next day. When I opened the box, there was no seal or anything other than the bottle; I don't know if the lids should have a sealed lid, but this did not. I shook the bottle, which you can hear is full and opened the lid. There was NO NOZZLE; I had no way to spray the sealant.
I tried to return and it took 3 tries to get to a person; the computer kept telling me that I could not return it.

Now I know why this was so cheap; it is defective, used, or both. What a ripoff. I wanted a different brand, but I guess I'll have to find that somewhere else.
