Polyurethane over stain.

Ross asked 10 years ago

Will polyurethane work over stained polyurethane? I have a board that is polyurethaned and I want to stain it (without sanding) and then put a coat of polyurethane over the stain.

You cannot stain over a wood finish that has any urethane coating on it… stain needs to be absorbed into the wood and this is not possible with natural (or even pre-stained) surfaces that have been treated with any coatings or even with wax…

Sanding might remove any coating but most likely it will give poor results… try a paint and varnish remover (follow label instructions) or better, try a furniture refinisher product… Good Luck!
