Additives to aid in paint drying

Is there anything that can be added to SW set fast acrylic to help it dry faster in colder temps? One hour spraying and 6 hrs to dry isn't cutting it.

There is nothing you can add to make the paint dry faster. You need to switch to oil base, for colder weather. Although I have used water base down to 40 degrees, and sunny. You should also keep a record on all the jobs, for the weather. It is something to go back on when you have problems with a job. You have to know your limitations. Those records will tell you that, and the problems that you encounter. Joe

I have been using alkyd paint for years, with no problems, in temperatures as low as 15 degrees. The paint is safe for traffic in 30 minutes or less, even with the thicker applications due to the increased viscosity.

You can try FRANKLIN PAINT COMPANY in MASS., they have excellent paint, it dries fast even WITHOUT their FAST DRY brand, And you should be able to get it for $5.85 a gallon minus a cash discount that's available, 1-800-486-0304. IF YOU ADD ALCOHOL TO IT ABOUT 2 TO 3 OZ. PER GALLON, IT'LL DRY REALLY FAST, THIS DOESN'T WORK WITH ALL WATERBORNES, AND THE GUYS WILL TELL YOU NOT TO, BUT IT WORKS!!
Adding ALCOHOL to paint...

In my recent adventures in striping (I HAVE JUST BEGUN), I have heard one person tell me I can use ISOPROPYL ALCOHOL (rubbing alcohol) to make the paint dry faster, now this seemed to work well for my first LATEX PAINT I got from FRANKLIN PAINT COMPANY, but now I am using a thicker paint from SAFETY COATINGS,WITHOUT THE STRONG SMELL, the FRANKLIN paint had, but it does not look to increase drying time at all with the ALCOHOL added. Now I know it depends on all the conditions, HUMIDITY, ETC., but is it possible not all latex paints dry faster with ALCOHOL?

Please excuse me but what the heck are you doing? If alcohol was supposed to be in latex paint they would sell it to you at Sherwin-Williams with instructions. Just because somebody tells you something doesn't make it sensible. I've even seen some people add diesel fuel to pavement sealers which is adding something that dissolves asphalt to something that's supposed to protect it! If you want fast dry times by a fast dry paint such as Sherwin-Williams SetFast or switch to chlorinated rubber or alkyd.

Thank you Don, Why would you add anything to your paint. As Don said, if you are that worried about the drying time. CHANGE to a fast drying paint or try the Hotline Paint from Sherwin Williams. Also, If it is not selected asphalt, use oil based which dry fast no matter what the temp is outside. And do not add Jap dryer to striping paint it damages the pigment.

I only used the alcohol because a striper suggested it in the first place, he said the alcohol absorbs the water in the paint and that is how he gets it to dry faster. Now another company suggested to use it because they use alcohol in their fast dry paint.
ADDING ALCOHOL TO PAINT

You can add alcohol to latex paint to make it dry faster. In standard latex striping paint it should not adversely affect the paint. I always add one pint per 5 gallons when striping at night. By the way I found out about adding alcohol from the manufacturer of the paint. It is what they add to the fast drying paint they sell. Good luck,

Ah Ha! I'm beginning to see the problem. If a person thinks, in error, that alcohol is just alcohol, that may be the problem. There are 2 types. If isopropyl alcohol, commonly sold in the health & beauty departments as rubbing alcohol, is used it would be counter-productive to drying the paint because it is considered a "wet" type of alcohol. However, if you buy a can of alcohol at a paint store or in the paint department of a Wal-Mart for example, you should be buying anhydrous alcohol, which is considered a "dry" alcohol. The anhydrous type is the primary component in gas line antifreeze additives. I suspect that's where the problem occurred with the alcohol post earlier. Warning: Do not get clever and think about trying gas line antifreeze as an alternative. Gas line antifreeze generally contains about 33% acetone, which is used as an extender because it is cheaper than dry alcohol, and also provides cleaning of the fuel line, carb, and/or injectors. The acetone will play hell with your paint.
Types of paint

I have had the opportunity to re-stripe some parking lots part time. We have used a fast dry Alkyd Traffic paint(not latex)and we were told to mix it with Toluene. One gallon of paint to one quart of Toluene. Is this a common practice or are there other types of paint that do not require mixing? Will this type paint work on most common jobs and run well through most striping machines? I believe ours is called a Lunay Liner and seems to be a few years old. Thank you.

One gallon of paint to one quart of toluene????.............That's a "Gypsy mix"...........good for one job and the money.....then drive 50 miles to the next job........cause you'll never get a second job in the same town.

The toluene will cause the paint to flash faster but be careful. If you mix that much toluene with alkyd, be sure not to leave it in your machine for a long period. It will shock the paint and make it solidify even if it isn't exposed to air. Then, you have problems with cleaning out the machine.

Could too much Toluene cause the spray tip to clog up after only painting a few lines? I was thinking that the paint was not thin enough. Perhaps it was too much Toluene mixed with the Alkyd paint. What is the best way to mix it or should it be mixed at all?
