I needed my small barn roof painted. I shopped around and found Lanco white sealantbboaint. When I told the painter how much I paid for it he was very skeptical about how good a job he could do with it. He is converted. He was amazed at how good it was. My barn looks amazing. This is with only one coat on so far.

Used it to seal up the wood floor and side panels of my utility trailer. Definitely protects the wood from road grim, weathering and rot. Very thick stuff, the coverage numbers are probably best case scenario, 50 sq ft per gallon is a stretch, not sure you can spread it that thin on wood (only reason for 4 instead of 5 stars), but that's why I got the 5 Gallon bucket. Cool to the touch even after hours of direct sunlight. I know its not exactly the intended use for this product, but it appears it will do better than anything else would. It keeps things sealed even where there is movement, flexing and vibration, I doubt that dipping/coating the wood in actual rubber would work as well. Will definitely buy more if I have other things to weather proof, I don't think I will ever need to weather proof this trailer again.

This coating is much thicker than paint. I used 3 coats of Lanco Elastomer Roof Coating on an almost flat room. The roof still has some small water ponding areas. No not leaks have been noted even after heavy thunderstorms dumped rain and hail. The dried coating is very bright white.

I gave this a 5 instead of a 4 because of the cheap price. There are better products out there, but not for 14$ a gallon. I used this on my old and worn out asphalt shingle roof to give it another 10 years without the labor and cost of replacing (yes I'm cheap). 2 coats and I'm happy- it's doing what I wanted it to do- 'hold' the shingles down, reflect the heat, and provide water proofing. After a light chlorine rinse, I rolled the first on at 65 square feet a gallon- don't think it can be rolled on any heavier. After dipping and rolling and getting nowhere, I started pouring it and then rolling it out- much faster and easier. Used an inch and a quarter roller which was shot after the first coat. 2nd coat at 115 sq. ft per and no dry rolling. I thinned down the 2nd coat by adding a half gallon of a tinted paint to each 5- I thought a bright white shingle roof would be too 'redneck' for my neighborhood. It's the only way to tint this product, and kind of difficult to get the buckets to match. A little tint goes a long way with elastomerics, and with a half in. drill and a paddle it went quick. So for about 1000 bucks and and some elbow grease I've got my new roof.

This product reduced the inside temperature 12-17 degrees on the inside of my home. It was applied over 17 year old shingles. I'm very pleased and quite impressed. It helped cut my electric bill in half and my ac doesn't run 24/7. In Florida, this product is a must. Highly recommend it.!!!!

    I Love it...
    Excellent product, no primer need, dry quickly and seal strong. I used in my mobile home metal roof that was leaking bad from few cracks and worked perfect.
