How to install Foamex

[Graham.Scanlan]

2 points,

10mm will expand and contract and will need fixings in place to allow movement.

if using solvent adhesive if the solvent gassing off has nowere to go it will come through the foam and cause the sheet to buckle (i have seen this)

and on another point why not try 2 or 3 mm di-bond/alucolor/rynabond etc

a lot less movement if any

[Robert Lambie]

moons right! i would opt for the dibond etc solution if possible…

one problem you may have though. if you are not fixing these sheets with anything other than silicon. you may find the sheets will slide before drying. do you have something that sill hold these in place until dry?

if it just comes down to, “you want to hide the fixings” then why not raise the whole panel on locators/fixing studs?
i have did this in the past and it looks good, a little bit different also.

How about the idea of using the fixings that are used to fix pictures flat to the wall??

It just poped into my head while reading the post, so it might be completely useless.

you would still be able to see the fixings at the side of the sign but not physically through the sign.

Hi Gray
If you dont mind the panels standing off the wall the then a system called split batton may be your answer.. if you have a table saw that cuts wood at an angle this is a piece of cake. slice a full length of 2 x 1″ tiber at about 45 degs. Screw and glue two lengths on to the board and then screw one on the wall so you can HOOK the panel on it.

Mark where the second rail has to be remove board by lifting straight up
now screw the second rail on. rehang the board. if you have placed the rails about 3″ from the top and the bottom of the board it will now be possible with a long drill bit and screw driver to put a couple of security
screw through the rail on the board and into the wall from underneath or
the top this will stop anybody accidently lifting the sign up enough to make it fall of the Hooks. This is Quite Hard to Explain so if you need a picture e mailed let me Know.

Bob your post has lost me completely, Any chance of posting a small demo??

[Simon Clayton]

Good thinking; that Bob..
we have used that method, but used foamex batons fixed to both the wall and the foamex panels.
Something to do with expansion of different materials.

hi gray
the panels are raised just like a raised flat cut letter is raised using a locator/stud glued to the rear. spaced out on the back something like this:

just tape a paper template on the wall then drill the holes for the female locators/cups to be applied then snap into place the panels. 😉

I believe Rob’s referring to the locators he used in his demo https://www.uksignboards.com/viewtopic.php?t=1855

They come in two parts and pop together like a press-stud, the part not shown in the demo is the piece that fits to the wall or whatever. It’s like a small section of tube closed at one end, with just a small hole through which you pass a screw into the wall.

Shout if you need a picture.

Hey Gray,
If you find out about these locators, post the details please. I’ve tried to find them as well but with no luck.

Better yet…If Rob can give us the name of the manufacturer, I’ll give them a call and find out an Aussie Distributor.

hi gray/leeroy
ill see if i can find anything more about them. i dont actualy know a manufacturer of them, simly because lots of places here supply them.
im very surprised they arent common over there.. maybe just under a different title.

leave it with me anyway. ill see what i can do.

funny enough i have a few demos im working on at the mo.. two have locators in them. 😆 😉

once you see them im sure you will both realise just how simple they are, but effective when used. 😉

[Lee Attewell]

Sweet Rob, I’ll look forward to that.
