Topic tags/keywords: spalted sycamore finishing problem

I have two test pieces of spalted sycamore. I’m using to test for my table , I was told they are hard to finish. this is what I’ve done so far, On one I used Minwax wood finish as a sealer coat and the other I used cut Polyurethane cut with 50% mineral spirits for the other sealer coat on the other peice, then I proceeded to rub the 50-50 poly hand rubbed on 1/2 of each piece, the other half I used straight brushed poly. I have 5 coats on each piece , hand applied and brushed and I still have dry spots on the wood. What should I do , my thoughts are switching to lacquer , if that would do any better on finishing or I guess just keep on apply more brushed poly, hoping that it will finally cover. Any Ideas are welcome

Light wash coat of shellac to fill in the pores and lightly sand then finish over the top, you’ll want to get as clear a shellac as you can.

Strip it and refinish with waterborne poly.

Waterborne poly REALLY raises the grain on sycamore (and not just on the first coat). Just a warning.
