I read and saw for myself that Kool Seal paint on the outside roof surface really helps to cut the amount of heat that is transferred through the buses skin. It also seals small leaks in the body. My question is..... Has anyone used the Kool Seal paint on the inside of the bus before you applied the foam board or spray foam insulation? I'm ready to skin my RTS and was wondering if painting the inside would help any?

First, it can't hurt. It will have more benefit on the outside. As you mention, it seals. Also it helps reduce heat transfer since it is white and adds some not conduction film where formerly there was none. On the inside, your installed insulation will do so much better that the effect of the kool seal will be rather small. On the other hand, if you want to seal the inner skin from any possibility of moisture contact, it would be a cheap and simple approach. |

I have been told to use something called ceramic paint on my roof. It is suposed to work like the space shuttle protection. I am going to try it in the next couple of weeks. I will now right away, being in FL near the gulf. It is warm all the time. I hope it works. Mike |

FWIW, I had purchased a 5 gal pail of it when doing our roof for the first time. It not only sealed up the outside, it kept the whole coach cooler in the summer. I had some left over from the 5 gal and did what I could on the inside before we did any walls or insualtion. Can't say for sure if it helped or not by doing any of the scientific test some of these guys on here do but it couldn't of hurt! I know my coach is water free NOW! It was far from it before! As a matter of fact, now that I think about it, we actually had LARGE mushrooms growing in it from the moisture. Those TOO are gone!

We used a product called 'TempCoat' on the inside of our coach...rear bath/bedroom only. The cost for us was very high ($200.00 CDN / 5 Gal.)
We noticed a significant difference (15 degrees) between the front and rear on a hot day.
I wish we had used it throughout the coach. |

Coolseal or the other trailer roof stuff from Home Depot suffers from being soft ( so it can stretch as the roof wiggles) and is great to seal a leaky teaky.
BUT the surface is not too robust and "chalking" , washing the sides of the coach with washed off roof paint does happen.
I used the creamic powder added to good paint & found the rough surface (like 200 sandpaper)held dirt , so the roof color was not too white after a while . A looser as its WHITE that reflects the suns heat.
Will not repaint till after Jacks gathering so all can see the diference between stock white paint & insuladd doped white paint.
White on white is the only way to stay cool , 1/64 of an inch of insulation doesn't do much as air (the best insulator short of a vacume) is R 7 per inch.
Save your money and yse the BEST whitest paint you can find.
Awlgripp or Imeron have about 5 whites listed , talk to the factory guys for best reflectivity.

Pete the roofer here,
Using it inside might cause a problem in the sence that all Elastomeric roof coatings are UV cured..you might have a big mess on your hands. I coated my old bus, in a heated lit garage and it took 3 weeks for it to dry, not cure but dry to the touch..it took another 2 weeks to cure.
Ceramic coatings are great also. Besides the Koolseal there is a company called Aztec roof coatings in Bighamtom NY I just started to talk to them about using their coatings for work and going thru the certification for a certified applicator. ( i do roof coatings for a living) all coatings chalk after a time just like all paints crack. Emron will crack too, just like the factory white on my Greyhound just like some of the 20,000 or 30,000 paint jobs on some of the nicer land yachts but as far as the roof is concrened it flexes more then anyplace..I'd coat it with an Elastomeric. Inside..I'd try something else, If your that concerned how about Rhino liner on the inside..its spray, waterproof and air dries.
Just a thought

My Kool Seal does get dirty, or it fades, or something. The manufacturer recommends retreating every two years. This takes and afternoon to clean the roof and roll on a new coat. I do it in the sun and it dries/cures rapidly. There are no cautions on the can about doing it in the sun as there are on regular paint. It has been there five years and is still going strong (with recoating). For the first coat, it is important to have the layer thick enough. This is accomplished by using as much as the label stipulates for the square feet on the roof. This took two coats on my roof. For the recoats, I just put it on until it is white. There is a considerable difference between the surface temperature of the dirty part and the recoated part. |
