Today I tried something I hadn't tried before: thinning oil-based poly with
paint thinner to make a wipe-on poly. Somewhere I read that the first
application should be a 50/50 mix. I actually tried 60/40 poly/thinner.
When I wiped it on, a noticed a significant amount of the stain was coming
off as well. Not enough to be real noticeable, but the project has 2 types
of wood: cherry-stained pecan, and also some birds-eye maple that I wanted
unstained. Luckily, I found the problem before I ran the poly (now
cherry-colored poly) over the maple. Is it supposed to remove the stain as
well? BTW, it is oil-based stain.
solvent for oil-based stain too. The same thing would have happened, although
to a lesser extent, had you not thinned the poly first.
Any time I apply varnish over stain, I always pour off a little varnish into a
smaller container and apply it from that container to avoid contaminating the
main supply of varnish. This actually isn't a bad practice to adopt even for
woods that are not stained -- sometimes the natural colors of the wood will
leach out in the solvent too (padauk in lacquer is a good example).
