Flash? Time

Hi guys. I am going to do my very first paint job this weekend. It's the suspension of my truck, differential, 4 bars etc. I bought PPG Omni paint, hardener and reducer. The hardener is MH 167 fast topcoat [advice of the paint store guy, working in a dusty area] The paint is MTK 2K Urethane. I am going to mix 4-1-1?. Spray a light coat and wait how long? What if I wait too long or not long enough. What am I looking or feeling for? Thanks for any advice. Peter

 

On your particular brand.....I dont know....However, I've found due too a few of my screw ups that test panels to figure out the material would do you good...

I know on Atco-Siekens that my flash times (depending on the tempurature and humidity) were about 15 minutes.....Auto Air Colors (Waterbased) flash times are extremley humidity dependent and about 10 minutes due to the thin-ness (Is that even a word?) of the compound.

Do a test panel....you'll be glad you did.

 

If you can touch it and not get paint on your finger, it's ready for another coat.(touch a taped area) Wait too long, the next coat won't "melt" in as nice.......too soon and you will get runs. I always seem to jump the gun...

 

Good advice, thanks guys. I was going to do a test panel anyways, but to figure out how to spray, not so much flash times. Peter

 

Tip for beginners:
READ THE INSTRUCTIONS!!!!!!!!!!!!

OK, if you are a newby, or picking up painting after not doing it for a while, or even using a new brand, or product.....be sure to pick up the "tech sheets" for whatever products you will be using, whether it's primer, paint, clear, or all of the above. The tech sheets go into more detail on ALL aspects of paining with this product. This means mixing, different reducers/hardeners, surface prep, spray pressure, tack times, pot life, tape off time, and time between different products.
ALL important stuff, not enough room on the cans to print it.
And believe me, different products, and different brands are all:
(can you guess?)

DIFFERENT!


Good luck!
