Re: WOW! NASA Technologie meets School Bus Roofs - Bus Kote

We used the hytech on our roof and I was impressed. Halfway through the painting I checked the difference. The temp reduction was amazing IMHO.

Hi! How is your ceramic paint today? Still happy of it?
I think I will buy it, just need to be sure.

Thanks

That's exactly the reason I want to use this on the roof of mine once I get it. Just have to find an outlet for it around here.

Hi Guys
This sounds amazing!
Please can I get some more details
Where and what do you order?
How much do you mix with what paint?

If you were to apply this to the floor, walls and ceiling inside, would this act like the spray foam?

Very interesting!!
Thank you
Howard.

Bus Kote

It's intended for use on the outside of the roof, and it also needs a clear coat applied after it dries.

I just ordered 3 gallons of each because I'll need that much to cover the roof of a 40 footer... 320 square feet if it was flat, more because it's curved, plus I'm taking the white all the way down to the bottom of the windows. 1 gallon covers between 120 and 150 square feet.

I used it when I repainted my roof before I built my walkway and solar panel frames - I bought the ceramic pixie dust and mixed it into Rustoleum gloss white enamel. Exactly how much difference it made is not easily quantifiable, but for a few dollars more on my roof repainting project I thought that any benefit, however slight, would be worthwhile. One thing I did notice is that Rustoleum with pixie dust dries to a rough surface texture, so after two coats of it I then applied two further coats of plain Rustoleum to smooth the surface somewhat. After six coats in total (Mar-Hyde etching pre-treatment primer, Rustoleum primer, then four coats total of enamel, all rolled on with a short-nap 4" roller), who knows how much difference it makes? It won't make things worse, and if it helps even slightly then that's OK. However, carpeting almost my entire roof in solar panels and the walkway means that little direct sunlight even touches the roof at all, and that helps more than anything else to reduce the interior ceiling temperature.

So, does it work? Maybe. How well - who knows. Is it worth doing? Yes, why not, but don't expect miracles. A smooth shiny gloss white paint is the single best way to reduce heatsoak, with or without the pixie dust.

The actual reduction in heat transfer that I have witnessed was quite impressive. As a result I am using the additive beads in quite a few areas. I have applied it to the inner sides of all my wall panels and will also be using it on my floor and firewall.

Here's an experiment I conducted with the insulating beads from Hytech:
Insulating paint beads: Feedback from REAL people please



TLDR: Bus Kote does next to nothing for heat transfer, but it does reflect sunlight which will reduce interior temperatures when in direct sun.

What may be more telling would be to do a comparison between paint with and without the ceramic magic powder, but to use a color of paint that is known to absorb heat (i.e. has a low solar reflectivity) such as matte black. If the powder then provides any benefit, it will be easier to separate the effects of reflectivity from conductance.

Anyone here want to do some test samples this way?
