anti-condensation paint

[happycamperbrat]

has anyone used this stuff? does it work? is it the same kind of insulating paint Ruthi uses? if it is coated on both the outside and inside of the roof and inside of the sides before insulating will it work?

I have never heard of that.   
But boy if it worked, it would be like the miracle drug   I wouldn't think that something like that would keep condensation out of your walls and roof. Because the moisture would still enter your walls and condensate inside someware. Do you know what the idea of this product is for? Is it just to keep water droplets from forming on the surface of the metal? It would be neat to get some literature on it just to see what the maker says.

I do know that this paint has been successful at limiting condensation on the outside of metal urinal troughs. One can extrapolate from there, I suppose.

What stuff?? do you have a link for us, sounds like snake oil though

I was just thinkin and googlin http://www.google.com/search?q=anti-condensation+paint&sourceid=ie7&rls=com.microsoft:en-us:IE-SearchBox&ie=&oe= from what I have read there are several places selling it. Mainly what I have read about is people using it on metal buildings. Most of the posts I have read are people like me wondering if it actually works lol If it does work, it seems a great option for a bus conversion. I wish Ruthie or someone using the insulative paint would respond and talk about condensation with their paint.......

According to these people http://www.johnstonestrade.com/product-range/product.aspx?product=Anti-Condensation_Paint the way it works is by absorbing the water droplets and then slowly releasing them back into the atmosphere over time. Hmm, it sounds like stuff I use in my garden soil in order to absorb more water and then as the soil around it dries the water is slowly released. The stuff I use in my soil is pretty expensive though and I have often substituted disposable diaper filling by tearing up a new diaper and using the gells inside.......... I wonder how this would work for insulative qualities too.....

I am pretty sure that when the temperature of a metal (or other non porous surface) reaches the dew point, moisture in the air condenses on the surface. The only way to prevent this is to keep the surface temperature above the dewpoint or cover it with a porous layer that can absorb the moisture as it condenses and later release it as a vapor when the temperature rises above the dew point.  Jack

This is a company that some bus nuts have referred to http://www.eaglecoatings.net/content/supertherm.htm for insulating type paint After snooping around on the site I also found this product which has pics taken inside a greenhouse to prevent condensation http://www.eaglecoatings.net/content/sunshield2000/projectpictures/Condensation.htm Thoughts?

Once we reach the dew point, stuff gets wet.

Whether that is waiting for the temp to drop in the evening, or the warm moist air inside the coach touching the cool skins or windows when it is cold outside, the wet is going to settle.

I'm no engineer, but I read too much...

At this point, I'd be choosing a paint for its rust prevention properties and then spray foam so the moist inside air never reaches those cold internal side of the skins. Or, when using the foam board of your choice, sealing the edges with foam-in-a-can to seal the spaces to prevent air exchange into the walls.

When someone does invent a paint that will prevent condensation, I expect that we'll have all manner of mainstream media telling us all about it, as it will be quite an achievement, and useful for many things.

happy coaching!

Jack & BW have nailed this in my opinion. You can change the laws of physics and nature.

Maybe you can, but only with Sales & Marketing deception.

I can not begin to think that absorption in to a thin layer of paint would make a significant difference, small if any.

[Ed Hackenbruch]

I think Gary meant  you CAN'T change the laws of physics.  Or do i hear Einstein rolling over in his grave? 

[happycamperbrat]

Okay, okay! I get it..... no one thinks this will work. You guys save me ooodles  Thanks!
