Works as advertised, at a fraction of the cost of its competitors. The smell is pungent but gone in 6-8 hours.

This waterproof paint is thick but spreads easily to form a waterproof membrane. I used it to line the interior of a clay pot I had broken into multiple pieces and glues back together and it made the pot reusable. The kit comes with a brush and some cloth to help form membranes although I did not need it. One thing to note is that the material is activated by exposure to air so if you dump out the entire enclosed pouch of paint you will need to use it in one go or it will harden. I cut a small corner off of the pouch and poured a small amount into a cup to test it on the clay pot. I am hoping it will not be a solid hunk of hardened material when I go to use it next time. I was impressed with its high viscosity which allowed me to paint the vertical surfaces of the pot interior without it all running down before it dried.

This is liquefied rubber. It doesn't cover nearly as well or as much as the container states, but it is liquefied rubber. I'm pretty sure it will prevent leaks; however, I used it on the roof of my RV which had already been sealed.

Very thick and rubbery. Applies well with a chip brush or plastic putty knife. I ordered this to seal up rusty pinholes in an old chicken coop corrugated roof. It is thick enough to fill cracks and small holes, and doesn't run quickly. If you need to seal up an old roofer anything you need waterproof that isn't under pressure, this is a great product. It should work well on RV roofs swell, since it's very similar the RV roof sealant I've been using on metal roofs, although this is thicker and may work better. The gray color looks fine on galvanized or aluminized roofs.

This is a nice all-in-one kit. It comes with the actual sealant in a pre-mixed pouch, a small brush, a plastic scraper, 5 sq. feet of polyester fabric and an instruction manual. Application is pretty simple. Clean the surface of the area it will be applied to, pour out the sealant into the bucket and apply with the included brush or use a small roller. If there are any cracks or openings greater than about 2mm, they suggest filling those before use. If you want to strengthen a small crack or area, you can cut a piece of the included polyester fabric to give it extra strength. It starts filming up in about 2 hours and cures in about 12 hours. I used this to seal the outer perimeter of the inside of a 2-car garage. I pretty much used up all the sealant on it. You really can't save any leftover material if it's been exposed to the air. Overall, a good product and does what it says. Definitely recommended. My rating method: ★ - terrible. I wouldn't consider buying it. ★★ - marginal at best. Doesn't meet the minimum requirements or quality to be useful. Buy it at your own risk. ★★★ - average. Meets the quality and requirements for a product of this type but is nothing out of the ordinary. If the price is good, I'd probably buy it. ★★★★ - better than average. Exceeds the typical quality of a product of this type and has a few extra features not usually found on other products of this type. I'd buy it. ★★★★★ - exceptional - far exceeds the quality of products of this type. Hard to beat the quality and features included. Best value for the money. I wouldn't hesitate to buy it.

This is excellent, waterproof sealant that's perfect for a variety of projects. It can easily be applied with a roller or a standard paint brush. It takes a couple hours to dry, but full curing takes about 12 hours. It cures without cracks and is very durable. It's highly effective and you can see water form into beads on the surface. This item is a good value for the money because it allows you to get more use out of your outdoor projects.

This is between a quart and half gallon size. Says on horizontal surfaces, it has a 10.7 cubic foot coverage which isn't a lot but in theory your using this for spot sealing. I have an old house and have had some water leakage on the roof flashing. Going to use this to paint the flashing to help seal it from rain. All water proofing paints are pretty expensive so this cost is on par with the others. I am pleased with the order.

This waterproof sealant goes on smooth and dries into a flexible rubber layer that really locks out water. I used it on a small roof patch and along a basement seam, and both areas stayed dry through a heavy rain. The neutral gray blends in without looking messy, and the quick drying time means you can get the job done in an afternoon. Helpful tip: Stir it well before applying and use a disposable brush or roller so cleanup is quick and easy.
