What would cause 1 shot paint to not dry. It has been over 12 hrs and it is still tacky. Used mineral spirits to thin a little. Any ideas of how to fix it now. It was painted on plywood panel that was primer with kilz primer. Could that be the problem. As you can tell I have only used 1 shot a couple of times. Thanks in advance. Clint
Mineral spirits is the problem. I used it with rustoleum and 3 days later in the summer it still was not dry.
Don't know where you are but temperature is very important for drying. Usually you can spray down to around 50 or so but I wouldn't do it any colder especially if you thinned it
It will dry eventualy. If you can get it somewhere warm it will speed it up. Air moving will help too. It sounds like you sprayed it on so this wouldn't be an issue, but if you don't get all the brush oil out it will hamper drying as it is a non drying oil. I use mineral spirits with one shot all the time. No drying problems.
That's funny, because I only use mineral spirits and one shot and have no drying problems...in about 15 minutes I can 'stripe over the previous lines with no problems...maybe it's a reaction between the Kilz and one shot, or the Kilz allows the wood to seperate the one shot...
I did not spray it. It was done by brush. I cleaned the brush before using it like always(but that could have been it). I just didn't know if the kilz primer that I used could have screwed it up. It is inside so it is not the temp. What is the best way to clean out the brush before using it to make sure that all of the oil is out? If that is the problem how ling till it dries?
I use OneShot, OneShot hardner, turpentine, and a drop of smoothie. I had OneShot freeze one time and rendered it useless then an old timer turned me on to the turps, been using it eversince.
Is it laying down flat ? The solvents the are using now are heavier than air. If the panel is laying flat,the fumes sit on top of the panel,and slow drying. Using Mineral Spirits won't help either. And if the Primer wasn't completely cured,that is another strike against you. Stand the panel up on edge,someplace warm,where the air can circulate.
There's no problem with mineral spirits or brush cleaning. It's with the tempatuer. I've had it happen to me a few times. The paint was on the floor or somewhere cold. striped it in a room that wasn't real warm and it takes a long time to dry. Get some heat on it and give it a day or two. It should be fine. Remember in the winter months to keep the cans warm if you are going to use them One shot is a slow drying enamel so you can work with it. It really don't like the cold. I did do a helmet one time for a friend and put it away so she wouldn't see it. It was in a box, I put it in the van overnight at about 15-20 degrees. It didn't dry. Even with heat. I had to wipe it off and do it again. Hope this helps, Don
I also wonder if at some point I have let my paint get too cold. From what it sounds like once it get too cold it is junk? I will try standing it on end because I do have it lying flat. Thanks for all of the help. Clint
I've had paint freeze,didn't make it any better,but it still worked OK. The only thing i noticed was it got small lumps in it. When 1-Shot switched to their "Lead Free" formulas in '04, drying times increased. I did an under painting a couple months ago,with Lead Free Ivory. Using the proper Reducer,and standing on edge,at 70 F,it was still tacky after 24 hours. Luckily,the latest formula from 1-Shot seem a LOT better. If you are paint over new Vinyl,like Naugahyde,it can increase the drying time significantly. The newer the Vinyl,the worse the problem.
My one shot was in my van in the middle of winter for a month, it never froze and it works just fine...I've never used any fancy hardeners or thinners or any of that stuff, is it really needed?
The problem is really twofold:I would bet that you didn't allow enough dry time for the Kilz and it is still outgassing.Second;if you have painted a plywood sign board or something similar with the 1-Shot(or Rust-O-Leum or any enamel)and it is laying flat,the thinners are rising up from the panel and falling back onto the surface causing the paint to remain tacky. I used to have this happen when I was painting sign board.I'd set it up horizontally on saw horses.An old sign painter friend told me if I did this to have a fan circulating air around the signs and they woyuld dry just fine.Trust me on this;it works. There should be no compatibility problems with Kilz and 1-Shot AS LONG AS THE KILZ IS OIL BASED.Latex based Kilz might cause a problem.
Did you leave oil in your brush, any oil contaminants and 1 shot will never dry. Maybe the surface you were painting on?
I was a 1-Shot dealer for over 30 years,,,I would guess that the kilz wasn't dry or the temp is not warm enough to promote fast drying. MEK can be used to help in thinning also a flood product called penetrol ( helps the paint flow without diluting the viscosity)as long as you are working with the oil base 1-Shot. If you are in a push for a faster drying time during the winter months try japan dryer,,,looks kinda blue in the can but does not discolor the paint,,,use sparingly And I know all the old timers know,,but might be some help tp the younger guys,,,never use wax cups for mixing 1-Shot,,,really causes adheasion problems. HRP
Thanks for all of the help. I set it up and it was dry within a half an hour. So I think that that was the majority of the problem. The kilz was oil based but I do not know if it was completely cured. I am glad that you mentioned the penetrol and japan dryer. I have used it for house paint but did not know that it would work for this as well. Thanks Clint
I'm bringing this one back from the dead... I read through each reply and ruled out a lot of the reasons given above but I am still looking for some answers. I did some striping on a vinyl garage stool using 3 different one-shot colors with the same brush. I thinned with mineral spirits and cleaned the brush with mineral spirits between each color. My orange and fire red dried but the lemon yellow is still tacky 2 days later. I also did some quick lettering on a plastic toolbox with the lemon yellow that same night and it is still tacky. I punch a hole in the top of my cans and plug with a screw to keep the paints from skinning over. I read somewhere on the internet that as the paint skins over each time the "drying agent" in the paint eventually gets used up and the last of the paint in your can will never fully dry. And I know everything you read on the internet is true so there's no reason to question that theory. Looking for help, anyone have anything that's not already been discussed in this thread?
Agreed! I wish I'd of gotten into striping 10 yrs ago. Probably woulda had this stuff halfway figured out by now. In the last few yrs of my experiences I've had this happen with a sign or 2 but standing em upright has always solved the problems. This one's got me stumped.
I sold One Shot for 30 plus years and without getting technical, Lemon yellow is one of the colors that uses a higher volume of V.O.C.s thus the density is over 11 percent which would contribute to drying slower. The weather plays a role on drying time also,Most of the sign painters I dealt with always kept some Japan Dryer in their paint box to accelerate the drying time. HRP
In cold weather we used to sit the tin of paint in a bucket of hot water for a while to get the paint warmed up before spraying.
