Polyurethane on a vertical surface

[aaro...@gmail.com]

Hi,

Is it problematic to finish vertical surfaces? I only have experience
with horizontal surfaces. I'm worried about streaks, unevenness at the
top vs at the bottom etc.

Thanks!

Try thinning the poly. This allows you to apply a much thinner coat so
there will be less chance of runs. IMHO projects look better with thinner
coats applied more times, LIGHT sanding & tack-ragging in between each coat.

With oil-based poly I usually thin with paint thinner - 2/3 poly to 1/3
thinner or there abouts, we aint makin watches here.

I've never used water-based poly, too new fangled for me. I just don't get
how water and wood can go together and produce good result. Anyway, maybe
someone else has some advise if yer using water-based poly.

good luck
Daniel
