Henry's Roof Paint

I'm having serious second thoughts about the Henry's elastomeric roof coating. I did a section around the skylights and am not satisfied with how well it laid smooth. It also seems to collect dirt easier than a smooth paint would. Once it's down you're pretty much done, can it be painted over with regular paint? Experiences from those who have used it?

No personal experience but I read about a lot of the issues that you just mentioned. I personally know a bus that pressure washed all of the tropicool off of their bus after a month or so. I personally am sticking with oil based enamels for exterior paint

Are these issues with all elastomeric paints or just Henry's?

Rubberized paint only holds up so long on a vehicle... I like regular paint.

elastomeric paint works best on a rough surface, and best of all on a rough vertical surface

If your roof is well insulated, water-tight (fingers crossed) and already painted a reflective white, is there any additional advantage to using something like tropicool? I've heard it has a tendency to get dirty, but lack of durability seems like a much bigger problem.

We applied ames elastomeric paint to our roof about a six weeks ago. Our experience is that it forms a tough shell (we did apply 3 coats and included ceramic beads). We have tested painting over the Ames elastomeric paint and paint does bond well. We did ask the Ames folks and they said it was fine to paint over their paint with a laytex paint. We first applied Rustoleum primer, then Rustoleum Professional gloss black to both the primed and raw elastomeric paint. The places where there was ONLY the primer did show small cracks. When these cracks were painted, they filled in and were mostly not noticed. The parts where the gloss paint was applied directly to the elastomeric paint adhered well and looked good. We set the test piece out in the elements for a few weeks and there was no change from the initial findings.


Today, we shot some PP&G AUE-300 gloss black 2-part acrylic enamel implement paint on part of the roof that does have the elastomeric paint. It does look nice. Time will tell the total story, but I believe it will be nice for some time to come.

Here's an older thread on the matter. I did a test of elastomeric paint vs white oil paint vs school bus yellow somewhere in the pages:

Anecodotally, I should add that I painted several coats of Henry's Solarflex on my bus's roof about 4 or 5 years ago. It has held up really well. Sure, it could use a cleaning (as could the entire bus), but it doesn't look bad, just a bit dusty. No yellowing or anything.
The paint pale provides detailed application instructions that _must_ be followed! Make sure to rough-up the surface with sandpaper. The product takes a long time to properly dry, so if weather is a concern move the project indoors or build a magnificient tarp circus tent (that's what I did).
The only places where it is peeling off are due to me hitting branches and other low-hanging objects

I have it and my roof looks amazing. The rest of the bus, not so much. I also feel it's done wonders in terms of regulating the interior temperature of the bus.

I believe we did 2 coats, used a roller. It did go on pretty smooth. It's very matte but really looks good.
