Q:Can o use this product on my rv trailer
by|Nov 22, 2023
1 Answer
Answer This Question

A:  Hi David, for your type of application is better to use the Ultra Siliconizer or Coolguard even though both Lanco roof sealers have a great adhesion properties, nonetheless we suggest for optimal results to have the surface prepared properly by cleaning it thoroughly and applying a roof primer like the Lanco Aqua-Proof and then applying the roof sealer. You may also decide not to apply the roof primer, but if so we strongly recommend and adhesion test prior to coating the entire surface.

        Q:Hi good afternoon do I need to apply primer before for this to workout?
        by|Nov 6, 2023
        2 Answers
        Answer This Question

        A:  It all depends on what you're coating over. If applying Lanco White-Seal over black roofing cement, the roofing cement will bleed through and will not be white like the rest of your roof.

        by|Nov 10, 2023

          A:  Hi Laura, you don't need to apply primer before applying the Lanco White-Seal .

            Re-coat camper roof
            Covered a camper top with 2 coats. Goes on with a long nap paint roller. Coats well, even, dries pretty quick. Coat in morning, low humidity. Re-coat in 24hrs. Use a thermal temperature gun, do not apply over 120f roof temp. And dont apply late in day as humidity picks back up. Good product.

            Used on South Florida Mobile home.
            Apply 3 pails on a mobile home in South Florida... went on with no problems and adhere to the existing shingles well. Heavy rains fell recently, no leaks.

            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.
