Dicor or kool seal for aluminium roof?

[Shore2Shore]

Hi
Our '87 bounder has a one piece aluminum roof that is still in good condition. Since the over the top summer last year in TX been thinking about one of the roof coatings.

Is there much difference between the main versions as in
kool seals coating for metal roof tops or the dicor rubber coating for metal roof panels? Also one I think called Hengs?

Love the sound of the heat reducing properties and possible sound reducing too.

When doing roof & vent seams is it better to coat the roof first then use eternabond tape & lap sealant? Or before putting the coating on?

Thanks for any info or advice/tips

Paul.

I've had 3 TT in the past with metal roofs and used the Kool Seal ---- that is until I found that Lowe's and Home Depot sell about the same stuff (Henry's) for a lot less money. The claim to fame of any of these concoctions is reflectivity as the actual applied thickness and chemical make up doesn't have enough insulative R-factor to be of much use. As far as longevity - all about the same

Do any seams, vents and hole repair BEFORE coating the roof. Clean off as much old coating, caulk, crud as possible - your repairs and coating will go much better if you spend the time to get the substrate really clean.

I think both Kool Seal and Snow Kote have a 10 year or better guarantee. I won't comment on what is best, but I will say that on a previous MH, we bought one of the "as good as" house brand elastomeric roof coatings from one of the big box hardware stores and it was thin runny junk. Dragged it back to the store and had to argue to get my money back on the unopened 5-gal bucket; was told too-bad-so-sad on the opened one.

Not surprisingly, we bought Kool Seal at our local Ace Hardware for the roof of our present coach.

Thank-you for the info :-) if anything looking at covering the ally roof as its a pita to keep clean & causes alot of the black streaks of doom...

I used the Kool-Seal on my Ford's roof.
My roof is 8 X 24 I put on 2 coats this year and used almost half the pail.
(they are not a full 5 gallons anymore)
THis stuff does really work.
It was much cooler than bare aluminum I had before.

Thanks for that, with the ally roof do you need to prime it all before applying the kool seal?

Had read the kool-seal site & noted all the prep & clean info just not 100% sure about any priming as they have the KS primer. Plus mention priming regular metal panels after cleaning etc.

Which KS did you use? The elastomeric one or the one that is specifically "ally roof coating"

Thanks again for the info & advice.

I used the elastomeric one in white of course.

Had a feeling it would be the "white" elastomeric one but just wanted to make double sure!! Thanks again!!

i had good luck using dyco 890, it is a petroleum based product.
