Silver paint formold in attic.
I recommend tinting the mildicide paint a tan color because any future black or white mold growth will visibly show up on tan paint.
There are two likely reasons for attic roof sheathing that is painted silver.
In order for paint to come close to the tested emissivity rating the wood surface must be primed with a primer base coat of paint first.
Silver ions inactivate metabolic enzymes in the bacteria s cellular structure.
If there was no fire there is one other good reason to use this sealant.
These enzymes are needed for the cell to eat and live without them the bacteria dies.
Your attic is made up of porous wood that loves to soak up paint instead of keeping it on the surface to create a smooth shiny film which would be required to be fully effective.
After a roof fire replacement of damaged components is the standard repair.
Home house mold what causes attic mold how to remove it.
If one encapsulates attic mold with a clear sealant like many mold remediation companies do future home inspectors and homeowners won t have any idea if the visible black white mold staining in the attic is.
Attics tend to have the perfect conditions for mold growth hot humid and an abundant food source with the wood sheathing.
Simply put it stops new bacteria from being made.
If the paint is a dull silver color there was a fire in the attic or in the house below and the paint is used to seal the smoke particles to the wood.
If the attic suffered mold as can happen for instance if the bathroom vent fan was not vented to the outdoors but instead just vented into the attic the cure would be to spray the mold with bleach let it dry then spray paint to break any contact with the cleaned surface and oxygen.
Silver paint is also sometimes used as a radiant barrier to reflect solar heat that penetrates the roofing back out of the attic and that type of silver paint would be somewhat reflective.
A few people will paint their attic white just because they think it looks better or think that it makes the attic look brighter when the attic lights are on while putting holiday storage boxes in the attic.
Rust oleum 5001 mold and mildew proof interior paint a bit of a different option from rust oleum this is an oil based mold resistant paint with an ultra low odor much more so than standard latex paints it too contains a mildewcide formula that guarantees that there won t be any development or spread of mold and mildew on the painted surface for the next 5 years it is also guaranteed to.
Attic fire and or smoke evidence.
Lo mit is a silver colored non thickness dependent low emissivity radiant barrier paint interior radiation control coating system irccs which may be used in almost any application where infrared heat reflectivity or diffuse light reflectivity is required.
Attics may be painted white to cover over evidence of a fire in the attic or home.
