Quick question: I just got a gallon of Rosco green chromakey from BD photo .. I have a wall, 7' x 15' in the basement that's nicely finished wallboard w/white paint on it now.

Any tips on how to best paint this wall w/Rosco paint, re whether or not I need to lay down a coat of primer first? or anything else I should know?

I was just going to put down a dropcloth and use a roller brush as usual for painting walls, and give it 1-2 coats.

I'm going to use it to do clips in Ultra as usual, then import into Vegas for NLE work.

Appreciate any tips on "painting walls w/Rosco Green Chromakey" paint anyone could share.. Also, any tips re making a curve from the wall to the floor? A great tip from one guy on another board was to paint the back of a lineleum tile sheet and curve it to the floor .. any other ideas?

Also, I got a large green felt 'key cloth from eefx.com via ebay and it's terrific, much better keying off it than the green thin cloths I'd been using.

Hey Ken
I would think if the wall is a finished wall that has already been painted then as long as it's clean it would be fine to roll the paint directly(especially with 2-3 coats). A linolem tile sheet does sound like a great idea, especially if you were able to tape it with that green screen tape. I've been using a portable green screen (retractable hoop with 8 X 10 fabric) in my small studio (which has all paneling unfortunately) but would like to make something like you're doing, I'm hoping you get a lot of response to this thread : )

Ken;
According to the manufacturer, surface prep is as follows:
Surfaces should be clean, dry and free from dirt and grease. Prime porous surfaces, except fabrics, using Rosco Tough Prime. If painting a new plaster surface, prime wall with a commercial primer/sealer designed for raw plaster. Then use Rosco Tough prime as a final preparation.

Ken, just to give you a heads up, a 7x15 wall may not have enought hieght to avoid a lot keying requirements. remember you need at least +6ft from wall, +you need to backlight the subject to avoid spill issues....etc.... Limited hieght will force you limited your moment and your camera angles to avoid excessive keying. Try drawing out a layout with subject and camera position and lights and test to see if it gives you a useable workspace.
