temporary sign covering backlit

[Signed Out]

Looking for the best method of installing a 10'x5' coro sheet to a backlit sign. This is a temporary sign advertising office space, the backlit sign doesn't actually work as of now so no worries about the coro not being backlit. The existing sign panel is 3/16" polycarbonate. Was planning on grometting the coro around the perimeter and a few throughout the middle. I'm in upstate NY and it is cold, was planning on using self tappers and washers to hold the coro on, but am concerned that the polycarbonate might crack without a relief hole? Any thoughts or suggestions are greatly appreciated. Thanks,

since you are planning on basically ruining the polycarb anyway by drilling/screwing to it, just slide it out and slide the coro in

You'd be better off making a banner at 4.75' x 9.75' and tying it off.

You're actually entertaining the idea of screwing through the poly and putting screws into it ??

I forgot to mention that this sign is pretty old and not working. Whoever made the sign originally bolted aluminum angle iron to the back of the poly faces. They did this because the extrusions didn't have a slot where the sign face should slide through, so the angle irons are keeping the sign face from slopping around in the trim/extrusions. But because of this the faces are cracked and broken in all 4 corners. So the faces will be replaced eventually, when they have tenants to put up on the sign. Also this sign was hit by something, probably a truck, and the extrusions holding in the sign face has a nice bend in it, and also bent the angle iron on the back of the sign. So we had the side extrusion off and couldn't get the face out, going to have to remove bottom extrusion... told customer that we would have to charge hourly gave an estimate and alos an estimate on screwing a banner or coro to the face... So hope this makes more sense now.

banner bag it then.

 

[Gino]

Without a picture, sounds like it might be easier and less expensive to replace it completely when someone wants to use it next.

Agree, banner bag that fugly thing.

Banner Bag? Gonna have to look this up. Guessing a 10'x10'+depth of sign, grommets around perimeter, or maybe just the bottom, drape over sign and tie grommets together?

Pic doesn't really show the damage well. On the bottom near the middle you can see the extrusion is bent. I held a straight edge to it and the bend is 2.25" deep.

yeah 1 big 12'x12' banner tied on sides/bottom. I did one for a 12'x25' sign 60' in the air. it was fun.

 

[J Hill Designs]

its 5x10 - need enough for both sides pat

ok so after doing some searching on banner bags seems most have the sides sewn together. So basically looks like a big box, with no bottom, that a really big flat screen tv would come out of. This is not something we are set up to do, we power tape banners, and on the occasion we need a sewn hem we usually use banner blanks.

Does anybody see any reason why zip screwing grommeted coro sheets directly to the sign face around the perimeter and some in the middle, would fail? I explained to the customer that the sign will be kinda fugly done this way, but that it would be functionable and fine for a temp sign. He agreed. Time is sensitive and I could have the coros up tomorrow, banner bags.. not so sure.

vhb the coro to the face or make a banner and screw it to the retainers.Trying to put screws into acrylic is a no no.

 

[PrintzandPatternz]

I would not zip screw to the frame. The way you speak of the box being bent and everything I would say that the box just needs to be replaced. If the acrylite is that bad and damaged id say throw white vinyl over the roberts and stick up the office space for rent part over it. Yes its winter but it can still be installed especially for temporary use since the boards and box will have to be replaced

Yes, zip tying CorX will fail almost immediately.... especially this time of year. I'll take pictures of one we did almost two years ago and it's still doing fine. I'll post it tomorrow. We left the ends open...... and tied them off like a zig-zag effect. It's a much easier instal than having the sides sewn shut, too. Ours was 15' across and almost 12' tall, so we needed 16' x 26'. Draped it over the top and tied it off. Took me about two or three hours to do it. Yours would be a snap. You could do it in about an hour.

:Oops: here's the picture. I forgot I had it.

OK thanks for the pic gino. We were thinking of zip screwing (coarse threaded self tapping screws) not zip ties. But seems this is a no no? I have reservations about it too, but if the coro was zip screwed, through grommets, with big washers, all around the perimeter and in the middle I thought it should hold up fine. But now I'm not so sure after reading some of these responses. Maybe zip screws and vhb tape?

Well now i'm going to consider the banner bag like you showed gino, but what about the bottoms? Seems like there is no real good way of closing them off, especially with the posts there.

 

[Signed Out]

Gino, are you more concerned about the coro ripping or tearing away from the zip screws or the zip screws themselves either pulling out of the sign face, or causing the sign face to crack? Just curious.

 

[J Hill Designs]

just tie around the posts. its easy.

 

[ChicagoGraphics]

Make a bag banner and just put it over and secure the bottom.

 

[Signed Out]

ok yes i get it the banner bag is the perferred method..

But....

Will the other method i described, coarse threaded screws thruogh grometted coro or banner to the polycarbonate face around the perimeter and in the middle, work/not fall apart?

 

[Gino]

Alright, we get it, you don't wanna spend any money.... or the customer doesn't. Wanna do this the easy way ??

Looks like your area to cover is about 30" x 120". Why not just take white vinyl up there and stick it over the copy there.... or just use a scrapper and pull the old sh!t off ?? You could reach that standing on the roof of your truck or a 10' step ladder.

The new sign is red background yellow text, full size 10'x5'. We originally were going to vinyl over the whole thing, but the back side of the sign is pretty uneven ground, shrubs, telephone pole, etc., not to mention the wind and cold this week, not really able to get ladders back there to do a full vinyl overlay. But we could manage to through in some screws and what not to do the coro, or the banner bag.

You are right I don't want to spend any more money then I have to to complete this job, it's been a huge pain since the begining, but I have learned some valueable lessons.

Was hoping that the method I described would get approval from more expierenced people on here, but hope in one hand and.. Just gonna push this job back a little further for the banner bag as I will need some material and such. I also think that coro signs attached withing the trim would look better than a banner bag, but if it might fail then I'm not going down that road.

Sent an email to the customer describing the banner bag and that it might be a better option, waiting to hear his thoughts, but I have a pretty good idea that he won't be very excited about it. Wait and see I guess. But to be honest I still can't see why the coro method won't work just fine, and probably look better.

 

[Gino]

Oh, I'm sorry. You were hoping for more experienced people's answer. Ya know what, I'd skip the bag idea and just screw your CorX up there and be done with it. I'm sure you'll be just fine. Git r' done.
