Rustbuster discuss how to perform a cross hatch adhesion test

[@benwilliams1396]

I have been using custom epoxy 4-2-1 red and using the LVLP gun from your site aswell. Ive been thinning to 20% however when im spraying the paint the texture is very rough and requires a lot of thinning. Im by no means a painter so im at a lose end as to why this is happening. The paint is stored inside but is used in a cold garage, i use a gas heater to slightly warm the garage and panel before painting yet it still seems very rough.

Hello Ben, I would suggest adding more air into the mix as it sounds like the paint isn’t atomising correctly. You’ll need to be around 3-4 bar and 44-58psi but it’s no fine art, what works one day won’t necessarily the next.
I would almost start again with some cardboard and set up at 15% thinner and work from there adjusting the air flow needle.

@@benwilliams1396 I think we can do this as a video, some tips for setting up spray guns.

@@uklam102 maybe so would be very helpful for people like me. I know the gun comes with instructions but it would be helpful to see what they affect in terms of to thick, too thin, pressures, temperatures etc
