Keeping Elastomeric roof coating clean?

I notice the same thing with Henry's Elastometric coating. Some yellowish stuff leaches out over a few week after painting as well. Never considered putting a glossier top coat. I'm going to research that. I keep a cover on my pup so it doesn't get too dirty.

 

Let us know how the oil based product works. I hope it expands and contracts well with the heat.

 

I'm just looking into painting my roof to seal possible non-visible pin holes. I was looking at Henry's Dura Brite 587 Elastomeric roof coating 100% Acrylic. Is this what you used? https://www.homedepot.com/p/Henry-0...e-Elastomeric-Roof-Coating-HE587146/202091035

PIA to need to re-coat to give the roof a decent cleanable surface. Anyone use the Silicone based roof paints (Henry Tropi-Cool or Black Jack Elasto-Kool 1000)? Did they have a better cleanable surface that the OP's experience?

Anyone use the Kool-Seal Elastomeric KST063-600 Acrylic? How is that surface for 'attracting and holding dirt'?

 

Would an Acrylic paint over the elastomeric expand and contract plenty (or better than oil based paint)?

 

Yes, oil tends to dry really hard and cracks more easily. Latex would flex and expand and contract more with the roof. The oil based might work if you prime well. Good luck!

 

The elastomeric house paint I used years ago did seem to have more of a flat finish than the regular paint I used on the north and east (less sun baked) sides of the house. But it has a green/gray hue. It'd not white and getting washed. ;o)
I'd hope to find a coating that does not have the 'get dirty and not wash clean effect'. But if that is the nature of the beast and a coat of white acrylic latex gives it a cleanable semi gloss finish, that's OK. As long as it is sealed and protected.
