Works pretty good
Working as expected. Couple things I noticed. 1. Be sure to stir the paint if it’s been sitting prior to adding solution. 2. Effectiveness does seem to vary between brands of paint. 3. Be prepared for overflow on 1/2 full cans.

Easy to apply, initial dry was fairly quick, held up in humid heat
I used this to waterproof a Halloween yard decoration I built. It is standing up to elements thus far, including heat from storing, some rainy days, and morning dew. It initially dried very quickly with a thin coat and took a little longer on the second coat, but I live in a very humid climate area. It cured well and has a semi-gloss look but is clear when it dries. It coated well, not to thin and no too thick. It definitely did it’s job and overall I am very pleased!

Weird marketing
First off I want to say the product was packaged very well from the manufacturer very nice. The part I found strange was there are misspelled words on the manufacturers packaging. Another thing is most product you buy have the brand name plastered all over it or in big bold letters this product you have to really search to find the brand name which I found very unusual. Other than that it comes with nice examination gloves latex type, plus a couple of stir sticks. The product applies very well drive quickly. Now I will have to wait a while to see how well it protects against the elements outdoors and how long that affect last may do a another review here in a few months to let you know how it went.

Exactly what I needed
I was skeptical when I bought it, more skeptical when it arrived because the tubs seemed too small to cover the wood backsplash I just put in. Then the product was like jelly. I applied the first coat and used the whole first tub. The gel worked great to get between the uneven edges and spread nicely. The second coat took about 1/4 less of the 2nd tub plus I covered above the cabinets. It’s transparent but did leave a sheen that ties the multicolored wood together. I’m very happy with this and will be ordering more for other projects.

Doesn’t work for Behr paint
Works ok except for Behr paint from Home Depot. I’m not sure if their paint has extra water content that doesn’t bind. But it didn’t perform the same as other brand paints I tried it on.

Great Water stopper
This works great! And it's basically invisible after applied. It's easy to install, and quickly. The water was coming in through the bottom of a brick wall every time it rained. I put this on the inside and no water has seeped in. Love it

Better than flex seal
Was looking for an alternative to flexseal, to hold in the sand between pavers in an area getting a lot of run off. I found this to apply a lot easier and was less expensive. Hopefully it holds up, although since it came with two canisters I still have another one as backup
