Black Liquid Rubber Waterproof Coating - 3X Stronger Sealant for Foundation, Pond & Roof Repair - Heavy Duty Elastomeric Membrane for Concrete, Metal & Wood - UV Resistant & Body Safe - 1 Quart

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.

It seems every bit as good as Red Guard, but much cheaper. It is easy to apply, but doesn't change colors to signal it is dry, which is a gimmick. It dries quickly.

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!

I don't often leave 1 star reviews, but this stuff is seriously awful... I paint for a living, and I also appreciate a cheap product that performs up to and exceeding expectations (which are usually pretty low because of the price...). This stuff obviously has a very low solids ratio and is incredibly transparent. I put two coats on a camper shower I'm building in a custom van and you can see right through it. I let it dry 24 hours with very low humidity and fans circulating air. When applying the second coat, it appeared to dissolve the first coat and I was getting all kinds of dried bits coming off the surface and spreading through the paint. No paint of any kind should ever do this... Painted this on a fresh, clean, dry surface of redguard waterproofing membrane which is a very good substrate for adhesion. Not I wasted 2 days with this junk and now I'm skeptical that any topcoat I use will fail because of the poor adhesion of this product... In summary, poor coverage, thin, weak, low adhesion... Any standard latex house paint would literally be better than this stuff with better coverage, and more flexibility AND at a cheaper price! Will use Flex seal next time around like I was planning to originally...

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.

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.

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.

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

Stopped the leaks on my van roof , good stuff

Dieses Dichtmittel hat meine Erwartungen übertroffen. Es lässt sich leicht auftragen – egal ob mit Pinsel oder Rolle – und verteilt sich gleichmäßig. Nach dem Trocknen bildet es eine starke, wasserdichte Schicht, die wirklich dicht hält. Ich habe es für kleine Lecks und zur Abdichtung von Oberflächen verwendet, und bisher ist alles absolut dicht. Auch die klare Farbe ist ein großer Pluspunkt, da es unauffällig bleibt. Klare Kaufempfehlung für jeden, der eine zuverlässige Lösung gegen Wasser sucht!

Facilissimo da usare, non vedo l'ora che si asciughi tutto e possa testarlo

👍

No se adhiere al material plástico
