Need screen advice for BenQ W1080ST

post #1 of 9
Thread Starter 
I am in the planning and design stage for my home theater and am wanting to do a DIY screen. The room will be light controlled in the basement. What I am looking for is a 100" screen with as much 3D pop as possible. I am leaning towards a RS-MaxxMudd LL mixture so far unless someone recommends something better. Was also looking at making the screen out of sintra. Has anyone put this paint on sintra and how did it look? I have access to a drywall finish guy that can make my wall very flat and could just put straight on wall if more advisable...

Please help me my head is exploding with all the information I have absorbed here in the last few days!!!

Thanks
Brian

Sintra & RS-MaxxMudd LL have been in bed together many, many times. Use it to your own satisfaction.

Spray all the way.

Do you know the Drill? Know the Gear?

What do you know? wink.gif

Yeah I got a Fuji airless sprayer... Only used it a couple times for some custom cabinets I made. Can you point me to a link for a method of the paint layers? Still put the layers of killz 2 down then the paint or more killz?? I mean I can spray the killz all day... Mixing the paint is no biggie. Spraying I can handle.. Its the different layers I'm cornfused about!!! Lol and I don't know much....

Most all Fuji Sprayers are pretty good rigs....and more expensive than most DIY'er would consider. So I'd venture to say you "all good'. I'd like to ask though what size Needle / Nozzle assembly you have?

After you make sure the surface to be sprayed is as smooth and even "texture-wise' as possible, you will use thinned primer applied using the "Duster method". Usually, anyone with experience using thinner Shellacs and Varnishes can intuitively judge how much material is going up, and the rate / distance / row overlap one has to maintain to avoid Runs, Sags, a build-up that creates Orange Peal, or Horizontal striping from not overlapping the rows enough.

One very important aspect to consider when using Drywall is the differences in texture between sanded smooth Drywall Compound and Drywall paper. It is very advisable to lightly skim the entire surface between the mudded Joints / Screw heads with Compound, let dry, lightly sand, then repeat over "everything"...once again...with a very light skim coat of compound. Then, after a light, even sanding, you'll have as perfect and as even a surface as can possibly be achieved on a Drywall surface. and that sir, will provide a very substantial advantage as spraying on the Primer / finish coats commences.

I apply at least 2 Coats of primer via Duster, lightly sand, then apply a 3rd coat.

Then with the Finish paint, I do exactly the same, except I will sand only if I feel it necessary...after the 3rd coat, then apply 1 or 2 more light Dusters after that. keep the coats very light by applying the spray from 14" and maintaining a rapid transit across the surface. And also, be very certain each prior coat is dry before applying another. Use raised / applied heat until the surface sheen is gone, then if possible, a light breeze from a clean "elevated" Fan set 6' - 8' away at center to hasten the paint into a truly dried state.

Thanks for holding on for a reply. I am looking forward to your ongoing effort. Painting a effective, over-achieving Screen onto Drywall is the epitome of DIY Screen making, and warrants doing what it takes to make the surface be as pristine and flawless as possible, owing to the fact that starting with Drywall eliminates so much expense and other concerns and considerations.

Will going straight on the drywall give me a better screen than using sintra?

As far as the sprayer goes I have 3 - 4 different needles and tips... I'll get the sizes when I get home. lol yeah I know its too good for a diy guy but I have an affliction that makes me buy the best tools...(snap-on, festool, Fuji just to name a few). Fortunately this hasn't been the case so much with my audio/video addiction..

Although much depends upon the state the Drywall is in, the primary advantage is cost, with the aspect of ease of installation coming roaring up behind. Also, it's always cool to be able to mount a PJ, splash an image onto the wall exactly where you want it to be...mark off the perimeter of said image (+2" all around), and then focus on / apply all your efforts therein / thereon. Afterwards, the Screen trim is cut / sized so that by simply overlaying the pieces onto the Drywall, the screen is perfectly formatted to the size / location of the image.

Hard to find much wrong with that method of doing things. wink.gif

Caveats involve having to do too much work to make Drywall be acceptable. Personally, I'll use Drywall every time I can due to cost,a nd system design / screen size requirements. Sintra is my "Fall back"
choice to avoid having to do too much work just to assure a virtually perfect surface.

Got ya!! Drywall it is.. I got a guy who does some EXCELLENT finishing.. I didn't get a chance to look at the sprayer nozzles yet.. Completely emptied the basement and demo'd it.. Now there's a big pile of drywall and 2 x 4s... Got 2 maybe 3 loads to take to the dump tomorrow if the snow holds off!! Then I got a clean slate to work with! Maybe a trip to home depot!!!
