Before I start, let me say that obviously Steven_B has "been there, done that" enough to qualify for giving sage advice. My following comments are not criticism or nit picking, just observations and replies.

Depending on the Spray rig used, how it's set up, and the 'wetness' of the paint mix, you might get zero noticeable overspray, or leave your surroundings looking like a Snow Globe went nuclear. I find it to be easy to limit the overspray enough that I do not have to cover anything more that 10' away, and then only a light dusting occurs when no ventilation is present to carry it all away. Purging via a fan pointing out the Garage door is going to be sufficent. If you can get a cross current going from a window to door, that's great.
Me myself? I'd not worry about a "Garage" at all, (well, you can cover the 'Beemer' if you want I guess....) because you only spend about 2-3 minutes behind the Gun for each coat. Keeping the garage heated and as Dry as possible is the thing to be concerned with the most. Purging after a spray session, then closing up asap would be the ticket if you just feel you must. I'd heat up, spray, keep the heat up, let dry, then repeat.
I would highly suggest you stand your board up and not try spraying it laying down.
He's got that one nailed.
Here is the short list of what I learned:
1) Flotrol is your friend (only use about 1/8th of what the directions say)
I find the stuff worthless myself, but I never used it in as small a quantity as suggested, so......?
2) Mix too thick = ugly spatters and bad words
3) I got better results using Wagner's 'Paint Easy' latex conditioner for thinning than water
First major difference in opinion. Water thins the best for "water based" paints, and hastens drying times due to effective evaporation tendencies. Conditioners lengthen the drying time. Not good.
4) When you think you are done mixing... mix some more
5) Always use a good strainer when you pour from the mix bucket to the sprayer
Very, VERY important tip. Also, if the Gun has a Filter, lose it. 1 Gallon Sock-type Strainers are the best. Have a can of water close by and place the used Filter into it after straining. You can come back later, rinse it out, and use it 4-5 times that way.
6) Use a work light shining on the screen while spraying
But directed inward from the side to avoid your shadow.
7) Always mix more than you think you'll need and stop spraying and refill well before the spraycup gets empty (to avoid ugly spatters and bad words).
Unless your doing a 140" diagonal screen, 22 ounces loaded will always leave you with a little to pour back into the can. But Steven_B makes a point without knowing the best'est reasons to load as much into your Cup as reasonable.
Gravity + Mass = both a greater and more consistant flow rate into the Mixing chamber of the Gun. It is after all, "Gravity Fed" and the more paint in the Cup, the more the weight of the paint bears down under the effect of Mass+Gravity.
That's my two cents worth... real world experience from the nubie.
Nubie (noob) no more!
