Mold stopped with Radiant Control Coating.


I have had two houses, that I know of, where mold on the interior wall was stopped dead by the application of our RCC to the exterior of the walls.

Some people with several degrees behind their name say the explanation I am about to give you, just cannot be.  But, here goes.

 These were two houses that were somewhat similar. They are within the city limits but in a farming / rural sort of setting. 

Both were very old houses with ZERO insulation in the walls.   One had foundation block walls, the other had stucco.   The foundation blocks were painted on the interior.  And the stucco house had painted wood paneling for interior walls.   The West  exterior walls of both houses were coated with the RCC..

In both cases, the West walls of the house were the outer walls of the bedrooms and bathroom.  In both cases, they were the coldest rooms in the winter and hottest rooms in the summer as I would expect of a West facing wall.

In both cases the application of our RCC to those exterior walls changed that.  They were now the coolest rooms in the houses in the hot months and the warmest in the winter months.  This I expected and told them it would happen. 

They were very happy customers. 

About a year later they contacted me and told me something else happ ened that I did NOT expect.  Both people reported they had always had a very, very bad mold problem on the West walls in the winter time.  They had to clean the mold off every week or two.   One described it as looking like long black hair growing from the walls that he swore the mold moved with any slight breeze.

In both cases, it came up the wall an estimated 3 feet on the lower part of the interior wall and that lower part always stayed damp in the cold months.

After applying the RCC to the exterior of those walls, stucco in both cases, the walls no longer stayed damp, the mold went away and had not returned.

About a year after that, I checked back with both of them.  Still the most comfortable rooms and the mold never came back.

I called the man that invented our product and asked him if he had ever ran into a similar situation.  I already knew the coatring would not allow spores to attach themselves to the cured coating because of its sealant qualities.  However, applying the radiant barrier on the outside walls and stopping the wet walls and mold on the inside, that was a new one on him.  

Maybe someone more intelligent than I can come up with a better explanation.  But, here goes.


Heat travels toward cold, cold does not travel.  I guess I should say Heat energy travels toward cold.  There is always some level of humidity in the air inside every lived in home, no matter how well the home is sealed from the outside.

The heat energy produced in a home travels to the colder wall  surfaces.  In the process of that happening, that heat energy carries some of that humidity with it.  The heat energy and humidity come in contact with the wall;  The heat energy goes on through, the humidiy stops there and keeps the wall wet.

The mold spores attach themselves to the paint and grow.

I cannot come up with any other explanation. 

Does heat energy carry humidity with it when it travels to colder surfaces?  Yes.  If not, how come the inside of our car windows were so steamed up at the drive in???

I have no idea if anyone else on this forum deals with interior mold or not.   This IS an energy forum.  Maybe you should ask your prospective customers if they have any mold problem.  You might be able to use that as an added benefit to adding a Radiant Control Coating to their energy package.  After those two cases I sure did.
