Whare do i get Sintra?

post #1 of 23
Thread Starter 
So i have a few questions, I have a Vewsonic pro8200 projecting on just normal white paint wall. I want to upgrade my screen i was looking at the professional ones that had what i was looking for and they were $1500+ that is just way out of my budget. So i looked at DIY stuff and i want to make the best DIY screen i can and it looks like painted Sintra is the best option but I'm looking at 120"x60" screen. I have read several post about getting their Sintra shipped at about 100$ everywhere I have looked at its about $120ish for the board than about $150 just to ship it.

So my questions is:
Ware can i get a good price on a 120"x60" Sintra board?

The pant i was looking at is http://www.goosystemsglobal.com/index2237a.html would this be the best option for a protector in completely controlled lighting?
(its in a basement with no outside light and I'm panting the walls and ceiling black)

Then fainlay is thier something im missing is their a way to make a better screen for <$400?


Thank you for any help.

Oh and one more thing, my projector doesn't have the best blacks so anything I can do with the screen to get better blacks would be nice.

Thank again.

Nowhere has it ever been stated that 120" x 60" x6mm Sintra could be bought and shipped for $100.00. Would that it be true. frown.gif

Just let me know where it is you live and I can locate the nearest Sintra Supplier.

And GOO? You can do better for less money, and keep within the limits of true DIY that does not involve using expensive "Made for Projection Screen" paints.

I live in Minneapolis MN. I just got a goo recommendation when i entered my projector information. What paint would you recommend for a projector to boost blacks in a completely controlled lighting environment at that screen size. My budget for the whole project is about $400.

Thanks!

you can also source Sintra/Komatex just a few miles north, in Blaine, MN.

i'm 95% sure that if they have it in stock... that it'll be cheaper from them.

you may have to 'pretend' you're a business customer who intends to order more in the future though.

I was about to start mixing and I wanted to check a few more painting threads and now I'm confused. With Sintra do i need a base coat or can i just start spraying? And if I'm doing 5-7 coats do need to wait 45min+ and sand between every coat? If that's true i probably wont be able to do it in one day, any tips on keeping the paint fresh? Sorry if I'm a complete noob but i have read over 20 pages of forum discussion and i think i have too many suggestions now.

Sintra is made to be painted on. No need for primer unless the surface has been damaged and deeds repair. Dust away!

Make that "needs" repair.

In about every paint thread posted it's stated that if the surface of the Sintra is pristine, and without any dark mar marks, it does not need any priming.

And nowhere is it stated that you must sand between every coat. At most, a light sweep sanding between the 3rd & 4th Dusters, and again after the 6th can assure one of the smoothest possible finish.

As far as the timing between coats, much depends upon the conditions you paint in. If the air is dry, and especially if it's heated, 30 minutes between Dusters is fine. I personally apply a "clean" raised fan to the surface (from 6' - 7') after 15 minutes to speed up the process. Dusters by their very sparse nature dry fast. Only after you reach the 5th coat should you consider waiting 45 minutes, and then ...as stated above...much depends upon the drying conditions. If the air is humid, and the Temp under 70 degrees, the it can be wise to wait 45 minutes, and absolutely beneficial to employ a Fan after 15 minutes.

I can usually paint a 122" Screen in 3 hours. Or in 4 hours under less than idea conditions. But I ALWAYS have a clean 20" Box Fan in my Tool box, and when I'm really rushed, I use a small, forced air Bullet Propane heater. But i must often do the buggers in one trip for it to be cost effective.

So i started painting and the paint is not coming out the way i thought it would are the drops too big?
post #16 of 23
That is a normal looking 1st coat.....the coat that always looks the worst because of the sparse coating.

To be safe, let that coat dry completely (2 hours) and then repeat only move a bit faster. (...what size needle are you using? 2.0 - 1.5 mm)

Have patience, and if you err, err on the conservative side, paint-wise. You can always add more very thin coats...but subtraction isn't an option for these thin paints when it's running down the surface in a rivulet..

This is what the same thing looks like dry i just need to go get sandpaper I'm thinking 600 grit:

Speedy, that's a pretty small degree of texture. It would be great if you could put up an actual image and make a determination based on how much of of that texture is actually visible.

Still, if you can evenly sand the surface with a ultra fine grit sandpaper (...with great emphasis on "evenly"...) and then apply 1 final light duster, you'd be at the most optimal point possible.

Most all who paint these Screens never require that degree of effort....but just the same, anyone who knows ultra fine finishes will tell you that such a final sand is usually a requirement for perfection. And lest we / anyone forget, these are Latex Acrylics...Water based paints. that's why we "wet" them.

Take it slow, Speedy, and you'll win the race I'm sure.

Took a bit to get the screen up I think it looks good. I'll leave it like this for a bit and if i don't notice any flaws all add the border (yes i know i need to adjust my projector).

Wondering if there is a good board supply place in Grande Prairie, Alberta?
