I have sprayed Deft exclusively once I experienced it. It is SO easy to work, easy to handle, quick, durable and ultimately the smoothest feeling finish I have ever worked with. It’s just fun.
Depending on the temp, 10 – 20% thin with lacquer thinner. It’s really not that fussy if your gun is good, but it does flow out better if thinned some. I use two coats on a 220 grit sanded surface, denibbing with 320 stearate paper between coats. With that simple and quick prep, the last coat flows out and dries as smooth as glass. I use a semi-gloss patina.
Since it doesn’t scum over in the can or gun, I just leave it in the gun between uses. I wipe the nozzle with thinner and hang the gun. A brief stirring by swirling the gun and it’s ready to go again as much as a month later. When refilling the gun, I pour thinner in first and fill the gun (gravity HVLP) to within 1/2” of top. Swirl it a bit and go.

Dan,

What kind of lacquer thinner are you using? The last time I tried to spray Deft (2011?) it congealed when I added the thinner. Unfortunately I do not remember the thinner ingredients. I had to clean out the gun with acetone to get rid of the mess.

In the past I never had problems thinning and spraying deft, so maybe they changed the formula to meet some VOC regulations???

I have not used any yet. Out of a gun. In the past I brushed it or rubbed it on.

I was just getting information as to what to do before I start my project.

Deft what? Don’t they make all kinds of finishes? I’ve never used any of their products. Im stuck on General Finishes, finishes.

Deft lacquer is a floor finish over here.
I’m using off the shelf lacquer thinner from the local hardware, nothing special. Did you perchance use mineral spirits? That’s almost what it sounds like and that’s what would happen if you did. You could use acetone as a thinner for Deft and it does accelerate the drying. Deft has been loaded with retarders because it is a brushing lacquer by design.

Dan,

I did use “lacquer thinner” but I do know there are many different blends under that name. Acetone came to the rescue to clean things up but I do not like using that as a solvent. Too nasty for my preference.

I’ve sprayed Deft out of my HVLP system. It works well, but I found that it needed quite a bit of thinning, on the order of fifty percent, in order to get it to flow out smoothly. Granted, I was still at the bottom of the learning curve where spraying is concerned at that point. If you are comfortable with your equipment, you can probably use less thinner. As for the deft congealing when the reducer was added, part of the problem may have to do with the fact that Deft doesn’t make a specific reducer for its brushing lacquer, at least, not as far as I know. I think that your best bet would be to start with a high grade medium lacquer thinner. Prior to thinning your whole batch of lacquer, add a small amount of your thinner to a slightly larger amount of deft in another container and allow it to sit overnight. Provided that there’s no sign of a problem with the mixture in the morning, you’re probably good to go.

Man, I guess I’ve been really lucky, because I’ve never seen it congeal or go bad like that. I just grab a can off the shelf and use it!

I use lacquer exclusively. I love the way it looks. I love how easy it is to use. I LOVE THE SMELL. I sometimes cut it a bit no more than 20% depends on the weather. I NEVER spray when it rains. I spray with a cheap little gun called a Critter. It holds a pint in a mason jar. Many light coats are the key. Here in warm California I can get six coats in a day. I hit the project with some 300-400 wet dry just before the last coat. The last coat gets some 600-1000 grit love after a full day curing. Then some Johnson paste wax. I used to use Deft satin but have switched to gloss as it seems to lay out better. I can bring it back to gloss or any thing below that with sanding.

I have sprayed Deft brand poly with a gravity feed HVLP and a 1.5mm tip. I spray it out of the can on vertical surfaces (to avoid runs). I thin it 10% for spraying horizontal surfaces.

Works great.

Get a decent viscosity cup … look up what your gun “likes” ... thin accordingly with whatever solvent the manufacturer recommends. I know, they tend to push their own products, and it may cost a few $$$ more … but, it is cheaper than all that stripper and labor which just may be the other option.
