Taco77 Posted June 7, 2020 Report Share Posted June 7, 2020 I accidentally put one coat of interior polyurethane on an exterior Cedar table I just made. Can I put exterior poly over it or do I need to sand off all of the Interior poly? Quote Link to comment Share on other sites More sharing options...
RichardA Posted June 7, 2020 Report Share Posted June 7, 2020 Go ahead and add the exterior. Just do it a couple of coats, to be sure you have it all covered. Quote Link to comment Share on other sites More sharing options...
