I want to speed up my drying time on this sign job I'm doing this week.....need to get the vinyl lettering on by Friday....if I coat the boards with color this afternoon...
Will I NEED to add a hardener to the paint to be able to do that by Friday?
it will have two full days drying time...
It's raining all week (yeah, I'm inside) the place where I'm working isn't really cold, maybe in the 60's.
Second ?....IF I have to add a hardener, can i add the same One Shot hardener to both One Shot paint as well as other oil based enamels? (I'm using Platt & lambert)
You should try to keep the shop a little warmer if you can. (70 degrees is a good temp) A little air movement helps, too.
Under those conditions, your signs should be dry enough to put vinyl on after 2 days, but do a "nail test". Dig a fingernail into a quiet little corner of the sign and see how soft it is before you apply the lettering.
A little bit of mineral spirits will help the drying time, but don't over do it.
Hope this helps... Rapid

Hi Adrienne, This might reach you too late in the day to help, but... If you have the hardener, yes, use it. And give it a full dose + a little for good measure. That 1-Shot hardener is fairly tame. Some of the more aggressive ($$$) automotive varieties will kick a sprayed finish in minutes when you dose it up. I use a Martin Seniour 8850 urethane catalyst that runs $80 pint. Ouch, you're inclined to use it sparingly, but lay it on, and it will set that paint within a couple hours. It has the same effect on all the alkyd enamels we've tried. Spray when possible, or brush as consistent and thin of a color coat as you can. And don't inhale it.

Well....I popped into Napa auto parts on my way downtown and picked up a can of hardener ($32 with tax) got to the place I'm working at, and couldn't get the can open!!!
I pryed off the 'childproof' plastic cap (I HATE those) that covers the real one but still no luck....asked several guys that were nearby to try it...no go.....
So, I rolled on the cream paint without the hardener,and took the can of hardener back home where I'll try to get the &^%$ lid off before trying tomorrow morning.
My hands STILL hurt from trying to open it.
Must be good stuff....it's sure hardened itself closed!

The old sticky cap eh? Reminds me of a couple things to keep in mind when using hardener - Number one, always wipe the rim off before putting the cap back on or you'll have that problem every time. Two, put the cap back on immediately after using or it'll get real thick from the air contact. And the last one is very important...don't thin your paint out with mineral spirits. A couple drops may be ok for quick brushing, but if more than a couple drops is needed, or for spraying, thin with acrylic enamel reducer. Another costly additive, but will save your cookies. Too much mineral spirits in a catalized mix will cause the catalist to crystalize, leaving sand-grain texture in your finish. A weird problem that we never get as long as we avoid the spirits. (Not sure if turpintine is as bad, but reducer is the way to go to be safe).

I agree wioth Joe and the mineral spirits thingie. I use #6000 reducer when working with #4007 Hardener, I believe it contains resins which also add to the gloss etc...
