Paint Mixing for Idiots

[Chaparralman1974]

Ok, I am going to apologize in advance for a dumb question....but math was never a strong point with me, so please be gentle. :-)

I am getting ready to apply a seal coat of epoxy primer to my project. I am using the eastwood epoxy primer which is a 1:1 mix ratio of primer to activator.....easy enough. Now, according Eastwood, I need to reduce this by 20% with a urethane reducer in order to use it as a seal coat. How do I do this on a mixing cup? I have a boat load of these.

Math sucks....plain and simple. In high school I dropped out of geometry because it was dumb and I would never ever need to know squat about angles. Well, I ended up joining the Marines and they made me a mortarman.....I guess Mr. Tuttle (geometry dick in HS) was right after all.

I'd go by the oz. marking on the cup... multiply however many oz you mix by .20...that'll be how much reducer you need

I total understand this.

The math thing.

I almost failed Algebra in the 80's .
My grandpa helped me through this issue.

Stay with me on this story.

I was a Knucklehead back then. (and still can be)

I would ask the math teacher,
Why do I need to know A+B=C ?

She said it is a Formula you apply to figure things out.
Years later I Totally Understand.

Grandpa sat me down on the back stoop of My Grandparent's home.
Then He proceeded to show me WHY.

At 17 years old I didn't need that.

Now years later I am a Machinist.

I not only use Trigonometry.
I know how to spell it.

Now let's get serious.

When you are getting ready to mix the paint you can give me a Call.

You have to use the KISS philosophy.

Just use the single digit stuff.

Think of this as Money.

If you have 50 cents of Primer./ 5 ounces of primer
Then you add 50 cents of activator. / 5 ounces of activator

This mix is = to 100%

You have a 1:1 ratio.

Then add 20 cents / 2 ounces of Reducer.
