L R Waterproof Sealant (Original Black,1 Gallon)

Very good, but overpriced with shipping etc!

It kept out the rain

Perfect for my Needs!

It is a relatively convenient waterproofing system, which stops water penetration dead. Painting it on can be messy. We found you really need turps [mineral turpentine] to clean up brushes and spills even though it claims to be water-based. Don't use your best paintbrush for this material - once used for this you wouldn't be able to use the paintbrush for regular painting jobs after. It dried within a day (strong sunshine, 30-35 degrees C/85+ Fahrenheit). I reckon at a more civilised temperature, it would take 2 days. It works well when you've got good access, provided you clean the surface, but there were a couple of situations where access was very tight and we couldn't clean/prepare the surface properly. This sealant has high viscosity, meaning it doesn't stick onto the surface if it's dusty or when we're poking the paintbrush in at a funny angle. It's not proper procedure, but we thinned it down about 50% with turps to overcome these problems, to get the first coat on. Second coat was then easier.

Really good stuff for cheap roof repair. I’d probably only use it as a temporary solution however as it does seem to degrade after a few years

I have an older 12 x 18 foot gambrel roof storage shed used for lawn mowers, tools, etc. There is no telling how old the shed is since it was here when we bought our place 15 years ago. A friend of mine said he'd never even seen roof tiles like were on my shed. Over the years I've lost a couple of tiles, the tiles were getting very worn and you could close the doors and see light coming through the roof. Needless to say, rain water was not my shed's friend. Thought about replacing the roof but the cost was way out of reason for a shed. Found this product and after reading the many reviews I though I'd give it a try. I replaced 2 roofing tiles and started coating the roof. I put 3 coats on the rood, a little less than 3 gallons. This stuff is amazing. I would have never believed it, but my roof is completely sealed. I can't even lift or separate the tiles now. There is no light penetration and we've just had 4 days of constant rain and there is no leaking. It does go on brown in color but soon changes to black. The first coat took a little longer but after that the second and third coats just went right on. I managed to get a lot on my hands but it washed off with soap and water. I had about 1/3 gallon left and since there is no way you can reseal the container I decided to coat the wood on my trailer. Can't say if that was a good idea or not but figured it couldn't hurt. For less than $200 I got a completely sealed roof that I expect will last many years. If not, I'll just get another gallon in a few years and re-coat it. I highly recommend this product. Read all the reviews to insure it will serve your purpose, but I am very thankful I found it.
