Essentially Yes...although it comes from a different Mfg. Some times it's actually priced a little lower as well.

thanks MM.

is there a reason to choose Sintra over the much cheaper white board?

The Sintra is specifically made to be painted upon. And it can never warp or deteriorate like a Hardboard. Still, TWH is less expensive.

ok so i'm not MM... although some have thought i was his alter ego

sintra vs 1/4 hardboard melamine from menards...
weight.

both materials can be used as free standing... well almost... as in neither requires a frame to be built. they both have the same surface texture on both sides and readily accepts being sprayed. but sintra is half the weight as the 1/4 hardboard melanmine. 6mm sintra is about 15-18lbs.

now with respects to TWH vs 1/4 melamine from menards...
surface texture and weight.
also, the 1/4 melamine hardboard from menards is not prone to warping.

by order of merit:
1) weight and size. lightest in weight and available up to 6'x10' for 130+" screen
2) 1/4 inch melamine from menards. heavier than TWH but also more free standing and not prone to warp. max size 49 x 97 for almost 100" diagonal. surface more similiar to sintra.
3) TWH. baby but smooth spraying surface. max 48 x 96 for 97" diagonal.

and for the Made in the USA folks...
Sintra - is the USA brand. Komatex is the import.

while it is not on menard's website...

the dakoramine product that menards carries come as large as 61" x 109"

it is my guess that this size would only come in 3/4" thickness... rather than 1/2" or 5/8"...and that my friends would mean that it is a very heavy substrate solution.

of course, as i stated superbowl sunday... forabout $30, you can special order menards melamine surfaced 1/2" hardboard/mdf in 61" x 97"... for a max of 111" at 16:9

...or course it's at least 3x heavier than 6mm sintra in this size

again, the product is dakoramine anything larger than 4x8 needs to be special ordered at menards lumber service area.

If you're pre-drilling the holes and screwing into the wall, will attaching just the sides be adequate, or do you have to put some screws across the length of the top and bottom? I'm wondering as having to put screws in the top and bottom means you no longer have 49" of height, and thus will have to reduce the screen size.

for the bottom... use a 1/4 trim or ranch casing... for the board to sit on.
if you use a small bead acrylic/silicon adhesive towards the bottom center...and make sure it is flat until the adhesive dries.

do the same thing for the top.

Ok, so the board will sit on the trim along the bottom which supports the weight. Screws on the sides. And then silicone adhesive in the center of the bottom and top lengths. I assume this is to keep the board from bowing in the middle? What if the wall itself isn't perfectly straight?

Here is a question: How would one recommend building a frame for something like the Sintra in order to mount it when you cannot simply screw or glur it to the wall? The wall that my screen is on has windows in it (They are blacked out but the wife will not let me rock over them) so I have to mount on something that protrudes from the wall...

I currently have a 104" BOC screen that I am pretty happy with, but I would like to build screen 2.0 out of something like the 6mm Sintra and increase my screen size a bit to around 110".

I used a 8x3x1 board cut from the material I used for the frame to mount on. It allowed my frame to sit off the wall just enough to clear the casing for the window.

yes. or even 5/4" decking board ripped in half. or even 2x4"... depending on how much/deep of window casing that needs to be cleared.

you need to find a 1x3 board with a near perfect straight edge... or 72" or larger level (using the straight edge).

the menards board is pretty easy to make sure it straight... a few shims might be in order. using the long straight edge of the board or level to make sure the board is straight... and after determining how much of the shim is needed... cut the shim so it is flush with the edge of the board. a little bit of adhesive caulk on the shim between the board and wall will hold it in place.

So from the advice in this thread, I built a screen from this material. I used one of the boards from Menards and cut the width down so that I had an inch or two extra on each side. I bought some metal clips used to wall mount mirrors, spray painted them white, and used them to mount the board to the wall. I tried using one clip at each corner, but the middle bowed out a bit, so I decided to go with 4 each on the top/bottom. When the projector is on, you have to purposely look for the clips to notice them. This worked out great allowing me to not sacrifice any height by using screws through the screen.

The border was some cheap ranch style casing from Menards, covered with velvet. I mitered the casing corners and cut it to length. My girlfriend bought the velvet so I have no details on it, I just know it wound up in the $10-$20 range. She wrapped the casing and stapled it on the back. I mounted it to the wall by shooting finish nails through it with my nail gun.

All in all, it turned out looking very nice and was very inexpensive.

ghostee,

Nice job on the screen. Plus your girlfriend was involved in helping out with HT.....better stick with her.

thought i give this thread a slight bump.

sintra get so much mention... and rightly so... but for the 100" and less crowd...
i highly recommend this as the alternative... especially if you are east of the mississippi.

make's TWH look like it came from the dollar store...
and you can often find it on sale for as little as $18.99.

best of all, it solid, weighs less than a 3/8" sheet of drywall...
and has the same easy to paint surface texture as sintra.

I now need to attach such a sheet to my wall, and I'm thinking that the Hangman cleat I got has screws that are too long for the sheet of melamine-MDF. Deck screws around the perimeter? Or finish nails, maybe? Anyone done this successfully and care to share their technique?

I suggest using 1/4" or 1/2" Plywood Shims glued to the rear of the material

I actually wound up using the trick pb_maxx recommended: screwing a thin piece of wood to the wall after carefully leveling it, setting the sheet of MDF on top of it, and then using just a few screws on the sides to secure it to the wall. The wood is thin enough that it'll be covered by the velvet-wrapped frame. I'll see about snapping a picture or two of the results.

You can now get the slightly bigger size 1/2" 61x97 for a 111" diagonal shipped to your local store for free. Cost is currently $39 - but likely goes on sale from time to time. You can order it online and have it shipped - no need to go to Menards and special order it.
