Congratulations to our winner this month @mdwall! We will DM you shortly.
If you guessed that this white stain is either efflorescence or lime run, you were entered into the drawing. We know that salts are being mobilized by moisture from within the wall assembly and are slowly migrating through the painted surface as the moisture evaporates. On-site investigation would tell us whether the salt is water-soluble (efflorescence) or water-insoluble (lime run). The underlying moisture infiltration issue would need to be resolved, but then we’d recommend testing Klean N’ Release for removal of efflorescence from a painted surface. If it is lime run, we’d test Vana Trol, but the existing coating would need to be inspected to determine if repainting is required. If repainting is required, we’d recommend complete removal of the paint with SafStrip, cleaning of the surface to remove all salts and then a re-coating with our breathable masonry coating, BMC II.
