I am pressure washing a log home that has been previously treated with a oil based stain. Pressure washing with bleach doesn’t remove the oil based stain. The owner bought a cleaner from Perma Chink and it isn’t getting the job done. There is a lot of graying and black mold /mildew on the logs. Some of the old stain is off leaving sun damaged wood. What do you suggest I do in this case? The customer isn,t willing to use a buddy blaster.
Thanks,
Jerry Miracle
Sounds like it should be ground or sanded. It’s the only other option other than corn or glass blasting it. If you have power washed it pretty hard trying to get this off, it will need to dry a good long time before staining. 2-4 weeks depending on the weather. May not dry at all this time of year in the north.
