Liquid Rubber Waterproof Sealant - 3X Stronger- Black 1L - Professional Grade Roof & Concrete Coating, Indoor/Outdoor Leak Repair, Crack Filler, Weather-Resistant Protection

This stuff works great. I guess I was not paying attention when I ordered it. I was thinking it was gallon size, but was quart size. I needed to fix a leak on the top of my cargo van and it did a great job. It spread out and covered all the seams and dented areas on the top of my van.

This sealant saved my leaking roof! The 35oz black formula is 3X thicker than others—applied easily with a brush, forming a rubbery waterproof layer. Sealed cracks in concrete and stopped gutter leaks. After 6 months of rain/sun, no peeling or cracking. Professional-grade but DIY-friendly—even covered 120 sq ft with one jar!

but it does a pretty good job on the old yellow rain slicker. Just be careful not to sit on anything until it’s dry. I was unsuccessful at getting it off my car seat.

Si son buenos materiales solo no lo hagan en el sol si esta en la sombra o no hace calor es genial

This stuff is not elastomeric at all. In fact it is thinner than cheap white latex paint. I was expecting a thicker elastomeric coating. I'm using this on large hummingbird feeders. Over time, the plastic feeders crack because of UV exposure. I then repair with epoxy, then normally coat with a flex seal or gorilla liquid rubber sealant. Have also used both on lining gutter connections when they leak. My problem is when I seal the cans of flex seal / gorilla, the cans eventually bend, and the lid won't seal. So half the product becomes hard. Quite frankly I bought this because it looked liked it had a screw on top vs. a metal can with a lid. I've put on 8 coats, wasted 8 brushes and it is still not as thick as 1 coat of flex seal / gorilla. Don't waste your money. You are better off buying a gallon of cheap latex paint - and it has better coverage. This stuff is worthless.

It can't go on over caulking. I was going to put new caulking down and then put the glue over it but instructions say no.

Goes on smoothly and sealed up the cracks on the basement walls without trouble. It’s been holding strong after rain.

This is an excellent product.The tubs are very welled sealed. No risk of spills.waterproof sealant claims to be a versatile and effective waterproofing solution both indoors and outdoors.I highly recommend this product as it’s easy to use and seems to hold up well so far.
