Brushing pre cat lacquer?

Brushing pre cat lacquer?

AZ in Colorado Springs

I've got a project to put up some paneling and trim. The paneling will be oak veneered plywood, and the trim is milled from white oak.

I spray pre catalyzed lacquer (from Sherwin Williams) for many of my projects, but this one includes five 4'x8' sheets of plywood. A big spray project for me.

I'm wondering about brushing the lacquer on the panels. It dries quickly so I'll have to work fast. Is this feasible? What about using a roller?

Anyone have experience with this?

Thanks

A retarder would slow down the drying time, not sure how it would work with the pre-cat lacquer

Sprayed a lot of that in the past, can’t imagine brushing would work at all. Too much area to keep a wet edge. Also don’t see brushing being faster than spraying either.

Why?

Bill Tindall, E.Tn.

What advantage would there be in brushing the panels? I could spray one in less time than it took to put it in position to spray.

I have something that looks like an easel with multiple pegs to hold panels and strips of various heights. This arrangement makes panels near vertical and quick to spray.

The "why": I spray small items in my side yard. On a board set on top of saw horses. (There used to be an old buffet there, but after three years of exposure it has collapsed. The top is all that's left. That's what goes on the saw horses.) So a 4'x8' panel seems really huge in that space.

Dave, the dry edges during brushing is the major problem I envisioned. You seem to have confirmed that.

So I'll man-up and rig up a support for the panels.

Thanks for the advice.

Hi Andy,

Think of one of those folding stands that people use to display plates and platters. A larger version of that works great for holding pieces like this. My son did a whole series of paintings that were almost 7' tall and 9' wide, and we rigged up a rack for them that worked great. One piece of junk ply and a couple butt hinges and you're in business.

Doesn't need to be much

Bill Tindall, E.Tn.

Prop the panel up on two blocks and a saw horse. But if you make an easel I predict you will use it for spraying and find it convenient for any sort of panel or board. I have sprayed miles of house trim on mine, up to 16' long.

I got to the point of spraying this week and it worked fine. Thanks for the advice and encouragement.

Part of my hesitation was having only an 8 gallon tank on my air compressor. I borrowed one with a 33 gallon tank. That was sufficient.

Get yourself a HVLP all in one unit. I've been using one for Years. Only way to go!

not the only way

Bill Tindall, E.Tn.

Conventional spray guns are more forgiving on technique and material viscosity. Any small compressor will do. I have sprayed with a small compressor used for nail guns. And the compressor will serve other purposes.

I had no problems with my set up, been using it for 15 + years. Also use it for latex paint. I do have a small compress for nail guns etc..

By the way I'm in California, and A lot of County's you can't use your stander Spry Gun. Have to use

a GVLP Gun.

You might find it easier to get an external tank for your small compressor. I have an 11 gal. "bomb" from Horror Freight that was very inexpensive. It is useful for intermittent use, as long as you don't run your compressor for too long at a stretch while you are filling it. You have to be careful not to overheat the compressor, and may have to shut it off to let it rest part way through the fill. The tank is also convenient for filling tires that are parked too far from the shop to reach with my air hoses or extension cords.
