staining window sill problem
Here is the summary of what happened. Our handyman sanded our windows
(Oak) then stained them with Chabot pecan stain( product no 8127).
After about 4 hours, he applied polyurethane ( Chabot Number 18010 )
The windows turned white in several areas, there was also change in
wood grain pattern. It looked like " blush" but not quite.This also
happened in window trim ( oak) however he did not apply any stain to
this area or sand just applied polyurethane on existing finish it also
changed color to streaks of white which later coalesced to form large
patches of light beige. Can anyone please help. We are not sure what to do.
