Paint Mix Ratios

Recommended Posts

I'm using a polyurethane paint with a 6:1:1 mix ratio (paint + 2 additives). Since my mixing cups do not have this ratio printed on them, I must convert it to ounces. Would this ratio be multiples of 6oz:1oz:1oz?

Thanks. It was interesting to see them mix the paint. They did it by weight, giving me 3/4 gallon of paint plus 2 pints of additives (= 1 gallon). At around $150, this is considered "low price" auto paint.

Not trying to confuse you but you may have a reducer as one of the "additives".

The reducer is used as needed not just automatically poured in.

1-Paint

2-Activator also called hardener

3-Reducer add as needed to spray/ varies with temp and humidity

Just trying to save you a costly mistake.

If your cups or mixing stick goes to 8 in any ratio scale, simply use that one column to mix the paint.

Example.. pour the paint to the 6 in a column. STAY IN THE SAME column and pour part B to the 7, then pour part C to the number 8 in the same column. This will insure 6:1:1

I've heard good things about it. Was just at a body shop trade show this week. Talked to the PPG rep and he tells me that product is very similar to Valspar single stage which I have used. We like it a whole lot. If the PPG preforms as well you should be very happy.

Best of luck on your project.

Phil, The mixing of the color using weight is right. Its a method that provides consistency for the final color. When I tint and custom mix my base colors, I too use weight, using a digital postal cale set to grams and keep track of the amount and eventually arrive at cumulative numbers for each color. When it comes to mixing the paint and reducers & hardners, then its by volume. I too want to look into the PPG line. I was only aware of the Concept line. Maybe someone can expalin the differance between this DelFleet and Concept. Think both are single stage urethanes.

I went to the grocery store and bought three nice glass measuring cups; one for each "ingreedient". I like the glass better than plastic because it seems to be a better and easier cleanup.

PPG's less expensive paint system is called "Shop Line". Previously they called it "Omni" and it costs about 1/3 what their "top of the line" system costs.

The first thing I noticed when I walked into the paint store was the wall-O-tints; dozens of colors used to mix the various paints. The standard paint lines must have over a hundred tints to mix. The less-expensive PPG Delfleet has much fewer tints, and is intended for fleet vehicles. Perhaps these hues more closely approach our old car colors which didn't have these exotic tints either.

But you often need those tints to match an obsolete antique color. Do you know that the final color of a paint compounded from several tints can vary depending on something as simple as the order in which the tints were added to the base color?
