Topic tags/keywords: primer finishing spraying

I need help!

I spray (HVLP) a lot of water based paint. Through trial and error I have finally come up with the right match of viscosity and nozzel to achieve a good final result. My problem is primer. To get it to flow out, I spray it liberally. According to the manufacturer, if put on heavy, it can take a week or more to dry sufficiently for sanding. I am using a high grade sandpaper that loads up almost immediately. I have waited 24 hours and it still loads the sandpaper.

Can anyone recomend a good water based fast drying primer.

I just finished shooting a water based primer (Zissner 1-2-3) on some raised panel doors and drawer fronts. I shoot just enough to get full coverage, then stop. By the time I finished cleaning the gun, everything was dry to the touch. Tomorrow, I’ll hit it with a fine grit sanding sponge and call it good. Only a few spots will even need that.

Primer always loads the sandpaper if you put it on too thick. You only need enough to cover the wood and give a good base for the paint.

Thanks. If I use your method I will save money both on sandpaper and primer.

Which gun are you using?

I use a Husky Pro conversion gun. I got it a few months ago and am still working on the best settings to get things just right. I’m pretty happy with it, so far.

You didn’t say what primer you used.

I am using “Zinsser Bulls Eye Water-Base Primer & Sealer”. I tried (“Sawkerf’s suggestion) spraying a very light coat and that worked much better. I was able to sand satisfactorily in 2 hours.

Another question – anybody know where can I buy “trim screws”? I can only find 1 5/8” and 2 1/4” When I build cabinets with double sides, I fasten the sides thru the shelf pin holes while the glue dries. I am looking for trim screws from 1 1/2” thru 3” (1 1/2”, 2”, 2 1/2” & 3”). The only place I found with all the sizes only sells in bulk lots of 1000 or more.

Have you looked at McFeely’s? I have several sources here in Missoula, Mt, but it is a little ways to drive.

I use the waterborne primer from Becker Acroma. It dries fast (as long as you haven’t flooded it) and won’t clog the abrasive. If you want it to flow better without thinning, put the pot in bucket of hot water for 30mins before spraying.

Have your say...
