I had a new cedar fence built that I shared cost with a neighbor. The neighbor coated his side of fence immediately after build was complete. I want to clean and brighten before I stain. Will the cleaning and brightening damage the coating my neighbor applied? I assume when I spray on cleaner / brightener and powerwash some will go thru joints and get on the other side that is coated. Will it cause streaks etc on coated side?
Possibly but depends on the coating brand he used.
