EMC Q&A
« on: August 08, 2015, 07:58:45 PM »
The instructions for the primer and the paint itself are apparently for pro's and not for us amateurs - they leave a lot of info out and assume that the users are pros.
What I want to start here is a Q&A topic and then everyone that has a question will have a place to go:
Attached are the spec sheet for the paint.
Common questions:
1) What tip size should be used for the primer and the paint (not explained in the spec sheets) and what pressure at the gun for us amateurs (it does give us product/min but .....)?
2) Do you need thinner or not? This seems like a dumb question but the product is thin already.
3) How long do you need to wait to "abrade" it" if there are runs or other things?
4) What grit paper should you use to "abrade" the hull if you wait longer than the prescribed time between recoat?
5) Cleanup - what should you use?
6) The product says it is "Buffable" - do you use any special product and do you use a specific grit compound at that time?

they do not give this because its only part of the equation, the same tip size in two different guns with two different pressures will result in different results.  They give the amount of flow you need.  You can put this paint on a little thicker than other topcoat

primer will need a slightly larger tip if you do not thin it.

Not much reducer needed for topcoat, I would say 10% minimum and you can go up to 25% if for some reason you need to (should never need to :))

If spraying the primer, then I would use reducer, just to reduce orange peel

thats on the tech sheet. 

primer can be sanded as soon as its hard enough to not gum up your paper.  220 or 320 for the primer.  If you let it get really hard (after a couple days) it takes a lot more effort to sand

paint needs to be sanded if its cured more than 12 hours (spec sheet says 16 hours), paint can be sanded with 320, anything lower will make scratches that will be visible through the next layers of paint

Cleanup - what should you use?

EMC has a wipe down and clean up solution.  We know its a clean solvent with no contaminates, which is what you need.  So many "problems" with paint can be tracked back to products used that are outside our control.  The reason to supply a clean up solvent is not to make people buy another products from you :wink2:, but so that we can reduce unknowns

The product says it is "Buffable" - do you use any special product and do you use a specific grit compound at that time?

You can wet sand with anything from 600 to 2000, just depends how much you're trying to fix.  After the runs or bugs are out, you buff with compound (3M is standard), then after that a buffing polish (again I have used the 3M)

As for tips:
I used a 1.8 on the high build primer but probably should have used a 2.5 tip - it's thick.


I used a 1.8 for the finish primer


I used a 1.4 tip for the paint


It seems I have some orange peel in the paint now and I'd like to take that out of the paint.  I have 800 and 1200. I'll see if I can find some 600 this week, it might make the process a little quicker.

I decided to abandon a sand down of the boat - I touched up some areas, finishing with 2000 AquaBuff and the gloss ended up being different when I finished so I'll leave the rest alone - still looks good.
