Question about Parkland Plastic Polywall

[Ultron]

Hi there....long time lurker.

I decided to take the plunge into the pj world. My AE700 is in route and I'm in the process of building my screen. I bought a sheet of Polywall (Menards in Naperville, IL) and I have a couple of quick questions I couldn't find in the forum archives.

First, which side is the preferred painting side? I plan to paint it with Behr Silverscreen, and I'm not sure if I should paint the smooth side or the slightly textured side.

Secondly, since the polywall is so flexible, what is the best method of mounting it? I've been thinking about using 3M spray glue to glue it to a sheet of the polystyrene insulation (pink foam board). Is that the preferred method? I'm working by myself, so I can't get anything too heavy. Maybe a sheet of pegboard? I want to make sure the glue isn't going to be visible (someone had that problem with Liquid Nails). Will the spray glue work on polystyrene?

Sorry for all the questions.....I've had some dead links on some of the FAQ's in the archive, so I thought I'd throw it out there.

Sorry about the broken links. I have gone thru the FAQ and fixed all of them (I hope).

If your intention is to have a painted screen, there really is no point to using the Parkland. You can just use a regular hardboard substrate and bypass the Parkland altogether. Since it sounds like you haven't built the Parkland screen yet anyway.

I think you missed the point of my first post. I looked at 1/2" MDF board and it's simply too heavy for me to work with and mount. I have noone to help me move that thing. I need something light to work with, and the polywall is light enough. I think the foam board would give me the rigidness I need, without the weight.

Parkland also sells a product at Menards called Durotherm Lite, it is in the same aisle as the paneling standing up, It is about 1/8 - 1/4" thick and does not require a backing to keep it flat, you might want to check that out if it is not to late, you could return the flimsy stuff. If I were you, with the AE700, I would just try the material as is first, you may find it looks great, you can't really go wrong with a Matte White finish as the parkland. The AE700 has pretty darn good Contrast and Colors for an LCD, I own and Z2 and love it...

I'm using the Parkland unpainted, and it looks very good (although I don't have anything to compare it to, it's my first screen). I have no inclination to paint it. It's attached to a sheet of pegboard, which works OK except that it is a bit warped; my project this weekend is taking it down and screwing/gluing a few pieces of 2x4 to the back of it to keep it straight.

I attached the parkland to the pegboard with regular glue, but rolled on with a paint roller to keep it somewhat even. I'm blanking on the brand of glue I used, but it wasn't liquid nails. I'd be a little leery of the spray glue on the insulation, I'd contact the insulation manufacturer and see if it would work and if it's safe (I'd worry that it could break down the insulation, I don't know if that worry has any foundation, though).

I think SirQuack's idea of the Durotherm would probably be worth checking out, because gluing the parkland to the pegboard is fairly easy to screw up if you're doing it by yourself (hard to get the corners and edges exactly aligned). And my piece of pegboard wasn't warped before I attached the parkland to it; I think it could be the glue drying that did it (although I haven't heard any similar reports here; could be I did something wrong).

Slightly textured side of Parkland is what you project on.

Good luck!

Thanks for the advice.

I actually have decided to go the pegboard route, since the glue on the polystyrene doesn't sound very workable. Too bad the pegboard warped. Do you think you applied too much glue? I'm thinking about using the 3M spray adhesive, with a few finishing nails on top for insurance (I can hide them under the velvet border). The pegboard is light enough for one person to mount, right?

i just got a panasnic 700 and am using a dirty wall. im looking to try the parkland now.how about applying it to a light frame using some sort of screws and then placing a border over that ?.

It's possible that my problem was using too much glue, although at the time I was concerned that I wasn't using enough. The problem might also have been that I put the glue on the rough, unfinished side of the pegboard (the non-glossy side), which could have absorbed it, perhaps.

The pegboard is light enough for one person to mount, but it is a bit unwieldy because of the size. I don't know what your method is for mounting the pegboard to the wall, but plan out beforehand what is going to be attached to what, so that you can make the attachments with one hand pretty quickly while the other hand holds the pegboard up and steady.

I'll be interested to hear how the spray adhesive works and whether you see any warping after a week or so. Hope it works, good luck!
