Rustoleum implement paint mix ratio?

davedj1 · May 9, 2018

I picked up a quart of Rustoleum implement paint today and some paint thinner. The can has no directions on it.
I saw a youtube video where the guy did five parts paint, two parts acetone and .33 part hardener.
I have never heard of using acetone for a thinner.
What say you all?
Thanks

Acetone is correct.

Hmmm, thanks for the quick reply. I guess I'll have to head to the hardware store in the am.
What is your thought on the hardener?

Never used hardener.

Rustoleum is formulated differently than most paints (acetone thinner, etc.). Hardener might or might not work. I would definitely do a small test first.

A web search might find something about Rustoleum hardener.

I checked - "Rustoleum hardeners" and there are several recommended. The hardener type depends upon the Rustoleum being used.

I thin Rustoleum with acetone all the time and have for 15 years. You need to thin more than you think. I spray a light coat outside on a warm day and then a few minutes later a slightly heavier coat. Works fine. I never use hardener because of the risks of lung damage. Lots of threads on that.

My experience is that Rustoleum works pretty well without a hardener, but be careful for the first month or so. It gets really hard and durable but cures very slowly.

Prefect timing on this thread. I have a 15 year old rotary cutter that is mechanically sound but could use a paint job. Thanks!

Can't say enough good about Rustoleum paints, I've used them for around 30 years. I thin with mineral spirits not quite half and half for great results.

The stuff takes a long time to dry but the longevity is excellent. You'll notice once cured the paint is impervious to gas and oil also.

Best of luck, Fred

Well I sprayed the top today. Overall it went OK. I thinned it according to their website to about 15% and then I added about a third of an ounce of hardener. I made 10 oz of paint at a time. It's not a real glossy finish, I couldn't seem to get a wet look. I don't know if it was today's weather or what.
I sprayed my winch with the Magic paint a month or so back and had no trouble getting that glossy.
Maybe the acetone? and the weather?
It almost looks like a matte finish.
