Paint Mix Cup

So I'm painting my 87 ram cab and the paint calls for 8:1:1 ratio. My gun has the 20 oz cup. The only mixing cups the store had at time was 32 oz.
With no 8:1:1 ratio section on it. So he said I can mix it by using the section were it list 20 oz
So 8:1:1 would I go 18 oz paint 1 oz activator 1 oz reducer to = 20 oz total?
It's my first time doing this lol

I would use 8 oz paint 1 oz activator and 1 oz reducer. 8:1:1



To double the amount it would be 16 oz paint 2 oz activator and 2 oz reducer. Always mix the smaller quanity and spray a layout to see that the material and gun adjustment are working for you.. Even the pros do this when dealing with a new or unfamiliar material..

Use a can, with straight sides, and make ten equal marks on a stir stick the right size to have the amount you want to mix at the top of your marks. Pour first ingredient to the eighth mark, the next to the ninth, and the last to the tenth.

Let's just make this clear, NO! That would be 18:1:1!

I have a number of mixing sticks like this. They should have one at your paint store. Here is one on ebay. https://www.ebay.com/itm/PPG-DOX-384...-/282391036123



As mentioned by idrivejunk the sides of the container have to be straight!

If you wanted about 20 oz you could simply go to 16, then add 2 and add 2. That's the same as 8:1:1.

Mixing cups will also have ounces too, and you can do the same thing.



Just remember 8:1:1 or 16:2:2 or 32:4:4 are the same.

Brian

And If you want less, then its 4:1/2:1/2. You can use the 4:1 scale but only use 1/2 of the 1 then the other 1/2 of it.
That ratio sounds strange, Be sure its 8:1:1 and not 8:2:1

Everyone should have a mixing stick with the ratios on it.
In my case I find that my mixing cup usually has dried paint in and on it and needs cleaning so I get the stick out which is also covered in dried paint and in need of cleaning just so you can see the numbers. if that will take to long I'll just get a regular old wood, paint stick and make a ruler, using a sharpie and a ruler I transfer the inches onto the paint stick. If I want 4:1 its 4" and 1" totaling 5". If its 4:1:1 that would be 6".
If 8:1:1 is to much material for the cup that way then you use the 1/2" instead of the 1" marks so it ends up with a mark at 4" another at 4 1/2" and one at 5"
Most of the time I use the empty vegie and soup cans from home with a mixing stick since clean up isn't my speciality and I cant seem to ever throw out my dirty disposable mixing cups.
A lot of the time you can use an air blower and blow out the dried paint in a cup ,that's pretty quick way to clean one but it don't always work.
