Good advice and cool tips. I have fooled around with sailboats for a number of years and copper has been used in painting hulls (for a long time) to stop algae growth.

Thanks,

If you spray a very dilute copper compound on the walls, mold won't grow.  It doesn't take much copper to do the trick.  Copper has been used for hundreds of years to inhibit mold and algae growth.  A few pennies in a fountain will keep it looking clean.  I can put a short piece of shiny copper wire in a jar of sugar water and it can sit for months without molding or fermenting.  Otherwise it only takes just a few days to get moldy.  You can get copper based treatments made to spray on plants at almost any nursery, or you can mix up your own using copper sulfate crystals (this would be my choice) used to kill roots in sewer pipes.  Copper Sulfate can be found in hardware stores in the plumbing section.  It's a deep blue in color.  You shouldn't be able to see  any color change on the wall after it's sprayed on, especially if the wall is already blue.  Copper in small amounts is absolutely safe for people and animals (except fish).  Copper water pipes are still used in homes today, not to mention jewelry.  Please note, copper will also kill water plants and fish at low concentrations.  It will kill regular plants in high concentrations, hence the use for getting roots out of sewer pipes.  Also note, copper will inhibit and kill mold and algae, BUT it won't remove it or take away the stains.  You may need to use some bleach and water to make the foam board look good.  Bleach might negate the effects of the copper, so try to get as much of it off the foam as you can before using any copper compounds on. 

 

Hope this helps.
