You guys drinking this stuff?

4 cabs, barely a gallon of duratex. 2 t48's, two DR250's, two of the biggest coverage hogs we build. The pics are of the first coat. Thin, thin, thin. Just make it black. Kinda like the Stones. You can see the grain through the finish it's so thin. I used barely a pint. Yes, I measured. Dries in about 10 minutes. The roller you see is a 4" foam cheapie. Don't roll too fast or you'll leave air bubbles.

I then rolled on another moderate coat, then a heavy one which I textured. It really doesn't need to be 1/4" thick to give you a good strong finish.

I get lots of questions about coverage.

Here is a Link to DaveK's spraying adventure with four DR200.

He fabricated a hangz-all from a tetherball pole to shoot four DR200 at a sitting.
This is a content picture that conveniently protects his new persona in the Witness Protection program.

I invited myself up for a Duratex spraying lesson.
The product is Duratex HB in black. The compressor was barely holding 35 PSI during the actual spraying.

The DR200s were brush painted flat black as a primer coat before shooting the Duratex.
The four DR200 took about 1/2 gallon.

Leland, is the standard grade better for shooting than the HB?

I have four T48, four OT212, and O15LB to shoot, and probably a couple other mini cabs.
Gallonage?

Spray Grade and Hibuild both spray well. The difference is the build Hibuild can be sprayed much thicker without fear of running, due to higher solids content. Personally I'm old school, mulitiple thin coats are better than 1 thick coat. Cure times are faster, and it's easier to see flaws when you're hitting it two or three times. These cabs got three coats. Even when I spray I will put the first coat on thin with a roller. Hibuild also is a little harder on cure and has a slightly different sheen.

Primer is the ticket though. Pisses SWMBO that I just won't paint period unless the surface has been primed. I didn't take a pic of these primered. 4 or 5 cans of Krylon flat primer. Every joint, filled spot and all hard to reach surfaces. Especially when spraying it's important. You'll waste a lot of dtx trying to spray the tough places. If they're already black, all you need is some texture inside the horn mouths.

I just wasn't in the mood to clean an airless, so I rolled these. I prefer an airless to a hopper gun, but it also takes a $2k airless to spray this stuff well. Not everybody has one of those.

3 if you're careful, 4 to be sure.

Is there a cost benefit to the 5 gallon can vs. five 1 gallon cans?
Shelf life?

I stored half of a 5 gallon bucket in my basement all winter, about 6 mos, and it's fine. Follow the rules:

1. Clean the top and rim off after every pour. Once it dries it can fall into the liquid and end up clogging a spray gun, or making lumps in a rolled finish.

2. Before storing, sprinkle water on what's left in the bucket. Very important when it's half empty or more! When you open the can again, you can either mix the water in, or if there's a lot pour it off the top, then mix.

Yes, but not a lot. I'm not stocking 5's any more. I used up the originals, never sold a 5.

Exactly.

Hell, I stored in the shop where it froze multiple times. Not a problem. Even the old stuff that wasn't supposed to freeze you could just add water and mix with a mortar paddle and it was fine.

I've got an unopened 1gal on tap.
Will order 3 more when I place the speaker order.

Is there a recommended flat black primer?
I know some paints (Krylon) have a reputation for not liking to bond with others.

DaveK bought a gallon of flat base, then had the guy fill the rest of the can with black pigment.
It was an extreme charcoal gray, almost dead black. It looks good as an undercoat.

[LelandCrooks]

I use Krylon black primer spray. No problems. AFAIK it's rustoleum that has adhesion problems when mixed with other paint. The fish oil base doesn't play well with others.

Just about any primer will do.

[Tim A]

Latex, no oils.

I've used flat black latex paint instead of primer. It's cheap, about $15 a gallon.

LeLand: Did you roll that with the standard Roller grade or HighBuild?

[LelandCrooks]

Hibuild.

[myn]

Thanks. HiBuild the ideal for rolling?

[LelandCrooks]

All of it rolls pretty well. The roller grade does roll the best, easiest to control the coverage and not leave lap lines.

[myn]

Whats the advantage of HiBuild over Roller grade in relation to rolling? Does the HiBuild offer a smoother or better finish or ?
