=Smooth=

6:1 (Paint:Catalyst)
25-33% reducer (consistency of 2% to whole milk)

Example:
60 grams paint
10 grams catalyst
115-125 grams total with reducer added

Spray at higher pressure with smaller drps of paint.  40 PSI



=Textured=

6:1 (Paint:Catalyst)
0-20% reducer  (consistency of half n half or even thicker depending on conditions (temperature) and desired texture.

Example:
60 grams paint
10 grams catalyst
0 - 40 grams reducer
110 grams total

Spray at lower pressure for larger drops of paint.  Hold further away to get desired texture.  20-30 PSI
Spray higher pressure to get smaller drops (finer texture) holding further away then you did for smooth coat. 40 - 60 PSI


Here's the deal you really have to play the texture by ear, especially when you spray in hotter conditions
the hotter you go, the less reducer... sometimes no reducer is appropriate.
I've sprayed on like 85 degree and hotter days and if you use more than a capful of reducer you're fucked for texture and will cause the paint to just flow out smooth.
