Confused again, reducer this time

[DanMcG]

I have Automotive Art Motocryl single stage that calls for a 2 :1 + 10% mix ratio.
I think the 10% is 10% of the paint and not the Paint and hardener. or is it 10% of the combination of the two?
Thanks

 

[Chris_Hamilton]

10% ( or any percent at the end of a mix ratio) is always based on the sum of the previous parts.
Easiest way to explain is to give an example.
2:1:10% is equal to 2 parts +1 part +10% of the total of the two.
example: 20 oz +10oz +10% = 20oz (2) + 10oz (1) +3oz (10%)

Hope that wasn't too confusing.

Not at all Chris, Thanks.
Why can't they just do it all as a ratio instead of tossing in a percentage.

I do it by ounces. Not the ratios on the cup. I'm always firing off numbers and my son is looking at my crazy

 

[MikeK]

Is the 10% not Reducer amount in a catalyzed mix ratio?
Just to clarify for those wondering what IS 10% of "what".
My Dupont cups have the 10% line on them. But Reducer amount is a "personal " choice also. Lol..

Your mixing cup will have a 2:1:10% graduations on it.

I got happy when Chris and Don liked my post....

My friend drew that up for me one morning when we were sprayed and the neighbors roosters were going nuts. Lol

I also mix by ounces. I can't remember the last time I went by ratios.

 

[Lizer]

Y’all should come do some lab math if you think this is fun.

I've never seen one with a 10% graduation, Do you have an example?
I mix by ml or oz's but it wouldn't hurt to have a proper cup.

One more question about this same paint: when using a normal/medium temp hardener (which is what I have) I can still use any of the reducer speeds available, right? I don't need to match the reducer to the hardener speed. Thanks

What's your temperature?

 

[MikeK]

Yes.
It's a personal choice often times,if you're experienced,as to the 'product/process of the particular work and desired results.

What's your temperature?

It should be in the high 70°'s so the Normal hardener (70°-85°) I have should be good, and just verifying that a slow reducer Is not an issue.

Personal preference here but i would use slow hardener too at that temp.

 

[crashtech]

Size of the job plays as big a part in these selections as temperature.

 

[DanMcG]

Thanks everyone, I used the slow reducer and I came out pretty good. A little more peel than I hoped to get. but I'm happy for now. This Motocryl has a hell of a shine. Thanks Chad for setting me up.
