I applied Bora-Care to a 4x10 doug fir timber and now a few weeks later there are tiny white dots all over the face of the wood. It looks like it could be a mold or fungus of some sort but also wondering if it could be dried product that didn't absorb into the wood. Please let me know.
If you are seeing white residue after applying Boracare, then there are a few possible causes. What usually happens is that either the Boracare was not mixed properly before it was applied, or too much product was applied to wood. Another possibility is that the Boracare did not have enough time to dry completely before the coating was applied. Typically Boracare dries in 24-48 hours. You can remove excess Boracare using soap and water, but we would try to avoid doing this unless there is clearly too much product applied. Another condition that could cause strange drying is if you are trying to apply Boracare to wood that has already been treating with paint, stain, sealant, oil, or another finish.
