Hello, I'm wondering if anyone would be willing to give me some advice
with a problem I'm having finishing a piece of furniture. The piece was
primed and then painted with two coats of latex paint. For finishing I
used Varathane water-based Crystal Clear Satin interior spray can. After
one coat it looks terrible--lots of globs of polyurethane. I realize this
probably wasn't the best product to use, but for now, is there anything I
can do to remedy these spots, or is stripping and starting over again the
only option? Thanks very much for any help.
Bad can perchance? I've sprayed waterbased lacquer and waterbased
polyurethane as top coatd over latex with no problems, but I used
gloss to avoid the flatteners that are in Satin. Make sure the latex
has cured before spraying/brushing. I've also used the pads touted
for trimming to apply WB polyurethane on latex.
Actually, I misstated something--the varathane spray was actually oil-
based, not water-based. But what I'm really trying to find out is what can
I do about the result--will sanding get rid of the globs, or do I need to
do something more drastic?
I have not used spray varathane but have used the stuff in a can that
is made to be brushed on. The brush on has to be thinned , otherwise
it does not flow well. I think you sprayed too heavy a coat,like any
finish multiple light coats are better than one or two heavy coats.
Fortunately this can be remedied.If you are familiar with a cabinet
scraper ( card type ) you can level off the high spots on flat work
with it. If you wish you can sand the high spots off, you will clog
the paper quickly though. When done clean up with a paper towel damped
in mineral spirits. You may need an additional coat of finish, any
brushable varnish thinned down slightly should be compatible with
varathane. Check compatability before using varnish.
