- What version of silver fire should I use.
Is 1.3 gain ok for this project
In a Light Controlled Theater with non reflective Ceilings & Walls, the N/C (No Colorant) version that does reach 1.3 gain would be ideally suited, and would assure you of excellent HDR performance
- is black flame better ?
is the patented Commercial version that uses 7 proprietary ingredients not available for general purchase, and that are selected for their more precise adherence to the performance qualities needed for the application. This is especially true should the addition of Colorant be desired or required. However, Silver Fire
has been formulated to come in a very close second, so for many, if ready local or Web availability of the needed components is possible, a fully DIY option is available.
-should I do this on drywall, if so how do I prep the wall.
Drywall is an excellent surface when properly prepared, not so very much so if it is not. For a Full Wall approach, a determination should be made as to the maximum sized area of the Wall that will show imagery, and within that area, a specific effort should be made to obtain a extremely smooth and blemish free surface.
Typically, the use of maximum sized Drywall sheets (54" x 144") are best so as to minimize the number of Tape Joints. Joints are then floated fully 8'-10" from center so as to create a very wide band of compound that can be effectively "feather sanded" out at the edges to the point of disappearance. If Drywall adhesive is used, a minimal number of Screws can be used to secure the Drywall to the Studs. When the final sanding of all areas that receive Compound is done, it should be done using a Large (3"x 9"x 1") Fine Grit Sanding sponge and with very light, sweeping strokes so as to avoid imparting scratches that might transfer through the Primer & Finish Coats.
A "sprayed on" Bright White Primer should then be applied (2 coats minimally) and then also very lightly sanded with the aforementioned Large Fine Grit Sanding Sponge.
-is Carl flex wire screen a better place to start.
Not for anything except for a specific sized / Format screen (CIH or CIW) and/or if the Wall itself is wholly unsuitable. I myself use a Wall whenever possible
