HELP! Polyeurethane over waterbase clear?????????
 

I have built a couple of small sized 10-drawer chests. 18"W X 18"H X 10"D
I decided to use the Minwax Polyacrylic finish on it. I have tried my best
to coat the tops without leaving brushmarks.

I bought the best water-base brush I could find, and I have tried at least 6
coats and still have not been able to coat it without leaving these marks.
I have even gone against the advice on the can, and thinned it out, for a
couple of trials. Nothing seems to work. I now have them sanded smooth
again with 400 grit. I don't seem to have this problem with Polyeurethane,
but I am afraid to coat over the water base clear with the polyurethane now.

Does anyone know if the polyurethane can safely be used over the water based
clear coat. Thanks, Ray

Put on a coat of Shellac and then the varnish of your choice.

Suggest dewaxed shellac to be safe. Zinsser Seal Coat is one or spray
cans.

Ray,

You might want to try one of those disposable .59¢ foam brushes when
you're applying Minwax Polyacrylic. I have had very good success with
them. Try it on a scrap piece to see if it meets your standards.

One other little trick that I picked up is to add one ore two of those
little "half & half" coffee creamers to a quart of Polyacrylic as a
de-foaming agent. It helps to remove the air bubbles.

....and don't shake the can - stir.

Doesn't the creamer make the Polyacrylic milky then, even less than it is to
begin with?

Thanks...

Hello Kate,

Actually, the one ounce to one quart of finish ratio doesn't seem to
have any visible effect. At least to my eye. The finish also seem to
dry its normal clear and hard; either glossy or satin depending on the
variety.

What works best for me is to buy the finish by the gallon and pour
about 16 oz. into a lidded plastic container. I then add the 1/2 ounce
container of half & half and stir it in. I drop in a 2" foam brush and
put the lid on. Now it sits on the shelf ready for use any time I need
it. Pop of the lid, retrieve the brush, and apply finish.
