Paint Thickness Makes a Difference
Today I just want to quickly go through something with you guys on paint viscosity, the proper temperatures to store it at, and also how temperature affects the paint. We send it out of our shop in Georgia ready to spray. Unfortunately, the warmer the paint gets, the thinner it gets. We actually can this for the thinnest possible case scenario, but in the winter time, and I know it’s starting to get winter where some of you guys are right now, the paint will start to thicken up slightly. This is just due to the structure of the paint. It just gradually tends to pull in on itself.
Mixing Paint For a Spray Gun
I want to show you guys what you need to look for when you’re opening your can of paint, and getting ready to spray. Also, bear in mind, throughout the course of a couple of months, while you guys are opening these cans up, and you’re painting, and then pouring it back in, the reducers actually evaporate off into the air, which actually thickens the paint up naturally anyway. It’s always a good idea to have some lacquer thinner, or urethane reducer on hand, so that you can just add a bit to the can, just to get it to the right spraying consistency.
What I’ve got here, this is a thick version of the red that we use. You can see when it comes off, it’s about the consistency of a cream. It’s kind of thick. It coats very, very heavy on the mix stick. This is one, which is the proper consistency. We like to say it needs to be somewhere around the consistency of skimmed milk. You can see how it runs off much, much finer. If I hold them together, you can see, the one on your right, the thin one, is actually dripping, where the one on the right, your left, is actually a much thicker drip, and in fact, a stream when I first bring it out. You can see the difference. You can see how it coats. You can see the thin one is already starting to dry on the stick. This thicker one is just still very, very glossy.
This will, of course, help when you’re painting. With it at the right consistency, the skimmed milk consistency, you will find that the solvents will evaporate much faster off the part, and the part will dry in basically 5 to 10 minutes in between coats. As it goes on really thick, if it’s cold, or if the can has been opened and closed a lot, that’s going to slow down your drying time. It’s going to also make you spray too much paint on, because it’s landing in a much heavier density.
That’s All There is To Mixing Paint For a Spray Gun
That’s it. Just something to remember, as we’re coming up to the winter now. Just make sure that when you pour it out, you get familiar with what it looks like coming out of the can, and into the gun. Once it’s in the gun, if you still think it’s a bit too thick, just add a splash of reducer at a time, until it gets down to the skimmed milk consistency. You’ll find that your painting is going to be a lot more successful. That’s it. Jason at ohwpaint.com, and we will see you next time.
