Well it took me most of a week to completely re-coat my RV roof. Tuesday morning started in by hand scrubbing the roof with a mixture of bleach, TSP and water. I did use a pressure washer to get the dirt out from under the roof air conditioner units. Took me a good part of the day to just clean the roof. Then I started in trying to peeling off the old very thin rubber coating. Well, three and a half days later, wearing our a pair of leather gloves, I through I give it my best shot at getting off the lose old thin plastic coating.
Saturday afternoon I started getting ready to start applying the Henry 887 Tropi-CoolŪ 100% Silicone White Roof Coating. First off cleaned out all of the old clacking above the roof gutter and replaced it with new Henry's clacking. Then mixed the coating with a drill and poured it out a quart amount in a paint tray. The Henry 877 coating pours out like the thickness of pancake syrup. Used a leaf blower to blow off any material laying on the roof. Started in using a four inch paint brush to do the corners, sides, roof pipe outlet, vents and air conditioners. Only did a 5 to 7 foot section at a time. Then used a 9 inch long by 1/2 inch nap paint roller to sped out the Henry's roof coating. Took about two to three hours to fully cover the 8 foot wide by 34 foot long 5th wheel roof with one coat. Next day applied a second coat.
1. Try to apply the coating a a fairly calm day. The wind can carry the coating in the air when applying it.
2. I applied the coating when the temperature was in the range of approximately mid 60's to upper 68 degrees. Sun helps, but I can not imagine trying to apply Henry's coating of any other roof coating on a day when it is approaching upper 70's degrees or higher. Too hot for me to do a roof!.
3. Weather: Have to apply the roof coating on when the roof is completely dry. Fall time and moisture in the morning is hard to dry off the roof and or have to wait for the sun to come out. Dampness or morning do can take several hours to dry off the roof.
4. Give yourself plenty of time to do a good job. The faster you try to apply the roof clacking or roof coating you are most likely of do a sloppy job and have mess.
5. Most Important: Slow down on the roof. If you fall off you will probably spend a lot of time in the hospital recovering if you are lucky!
Conclusion: I worked like a dog for nearly a week trying to bet the Fall weather.
Wished I could of done the roof repair/coating in better weather conditions. Sweating bullets all week worrying about the possibility of rainy weather. Got lucky this time around! Henry's 877 when on fine, thick enough to be impressive and I believe I made and hope I choose the right product.
