PPG Concept storage

[Brianfrench65]

I have about a quart of one color and about 2 1/2 quarts of another color, in 1 gallon cans. It is PPG Concept, acrylic urethane paint. I would like to filter and pour into pint cans, hoping that it will last better. What can I use for a thinner, to slightly thin the paint, and not compromise the paint?

I've heard that thinned paint should not be saved. I would just fill cans with least amount of air space and store in a cool place. Save the filtering for when you use the paint.

Awesome, thank you.

I always store paint cans up-side-down. Making sure I apped the lids down of course.

The reason.....50 years ago, a guy that trained me in body work told me to!

I suppose it makes a better seal. Also, as little of air left in the can the better as already stated.

Brian, thinned paint really won't hurt anything and I suspect what Harleytoprock was pointing out deals more with trying to save catalyzed paint (paint that has hardener mixed in). Fill the pint cans where there is minimal air inside, and you will be fine.

I have stored less than full quarts cans of PPG concept paint for over 13 years. I have used the paint periodically over the last 13 years for touch up jobs. I have had no issues with using the stored paint.

Even mixed catalyzed paint can be saved quite a few days in the refrigerator. A friend showed me this.

Thank you all, very much. I really appreciate the wisdom of the members.

Thank you.

I was given a few dozen gallons of Dupont urethane(Imron)years ago.It was from a truck fleet that used it on their frames and axles.The insurance company told them,no more paint on the premises.They had been letting the paint work out for a few years anyway,so it was given to me.It is all dated 1977-78.I never planned to use it on anything critical,but I used some on one Model A in 1988,another in about 98,and on my roadster pickup about 8 years ago.It seems fine.I used the rest of an opened gallon on my Dodge pickup frame last week,not sure if it was one opened 25 years ago or 8 years ago.It acts like fresh paint.The activator is all from the same era,it pours out of the can kind of golden looking,that may be what it is supposed to be.I don't know if the solids separate out while sitting,I never think to put a stick in it before I shake it,but two minutes of shaking is plenty.

Glass marbles! I was given a 12 year old quart of color in a can with plenty of wiped drips on the outside. The guy that gave it to me said to be careful pouring it. The can contained only about 1/2 paint plus marbles to take up the air space inside! When I opened it the can was full to the very top and the paint was like new. Of course, marbles were cheaper 12 years ago.

it will not harm concept to thin it. use any one of the PPG DT thinners to thin it. first thing first make sure you stir it up good so you end up with the same color later on.

Don't know if it's considered ok, but I save left over paint in glass quart jars. It stays fresh, and there is no worry about cans sealing. I don't trust the seal on a paint can when its been opened and closed several times.

All great tips! I will add one of my own, as far as I am concerned not letting it freeze is the most important thing other than making sure the lid is fully secure. I have many thousands of dollars worth of paint in my mixing room & I have my building set to 50 degrees at all times I am not in there.

[J Franklin]

At what temp, do you thinks the solvent will freeze? - 300 degrees?

I think that the paint will store ok in full cans, but hardener should be refrigerated.
