fixing foamex to brick / wood

[Bill Dewison]

You can use a high bond tape. Nigel posted in another thread, a link to dorotape. They apparently sell high bond d-sided tape that is strong enough to do the job.

How big is the largest sign you’ll be fixing?

your can get screw caps from most hardware stores, basically like the number plate caps, open cap put screw through, screw panel in place close cap, looks nice and neat. Remember to include holes in your design don’t want them going through design or being to close to edge about 25mm in. (Tip) drill holes in foamex @8mm screw caps are approx 10-15mm so they will cover the hole, if you just then pinch up screw this allows for a little expansion/contraction in the foam board.

well http://www.dorotape.co.uk will no doubt deliver it to your door, not sure about more local suppliers to you though. Nigel was posting in response to a question I asked, which bizarrely was pretty similar to yours 😀 So I’m as much in the dark supplier-wise as yourself.

If I get through to Dorotape on the phone Monday morning though, I can PM you all the prices etc. and ordering details.

As I understand it, this high bond tape will hold something like 30lbs per square inch, some brands are stronger than this. Foamboard being so light, you shouldn’t have a problem. 😀 Anyway, the stuff is called foamed acrylic high bond tape. I’m going to be using it to attach 600mmsq 5mm foamboard to walls etc. so pretty similar usage to yourself.

Wonder if it’d stick dibondy type stuff to walls, thats fairly lightweight as well 😕

Whatever screws you use make sure the hole in the foamex sheet is slightly bigger than the screw to aloow for expansion etc

Dewi,

The Doro Ultra Bond Tape is reccomended for use on aluminium, steel and powder coated surfaces. Not wood and brickwork. I’d be very wary of using tape on a dusty building!!

You could try ‘No nails’……..which I’ve used with great success on small car park signs.

thanks for the info everybody i will look for fittings at my local b&q i have found that they have a good selection but if you find what you want they have about ten per pack if you take them to small supplier of fixings you can get say box of 100 reasonable the tape sounds the best to me the building is red brick and the signs are the usual no ball games private road etc
for block of small flats ime trying to price the job to cover my costs and get a foot in the door as i am learning would that be the right way to go or?
i have tried no nails on other things but find it a bit messy or am i doing it wrong
back to my normal job till thursday
all the best

I hadn’t considered using liquid nail for the job, does it bond tight to the foamboard Martin? Really bizarre, as I use a product called Gripfill all the time for various jobs as it bonds in a similar way to liquid nail, but it also acts (as the name suggests) as a liquid filler. I hadn’t considered using it for plastic products as well as wood.

Would the tape work on a wall if the wall was sized with a PVA-based glue prior to the installation? I’ve worked with this method in the past when working on property, kind of sealing the dust on the walls before I apply a coat of plaster or paint or whatever. Unsure whether this would be practical. Presumably the liquid nail range of products, such as NoNails would have a little difficulty on some types of wall, just trying to come up with alternative solutions. I think a sign looks better with no visible fixings, and if I can come up with ideas to hide the fixing method, all the better 😀

I’ve only used it on small `12″ x 6″ signs and to my knowledge they are fine. At least I haven’t had a call to put them back up! A liberal sausage of No nails randomly spread on the back, push against the wall, hold tight and roberts your mums brother! No Nails is really Evo Stik in a different format, I think!!?

If in doubt I’d probably use a combination of No nails with a single screw either side. Much easier to fix and rawplug than the full 4 corners monty.

I just thought I would submit an experience I had with using Double sided tape 😳 …Some months ago I had a small job to do in a betting shop – 5 small oval acrylic signs 6″ x 4″ appx these sat above a bench over a light box where customers would sit and write out their betting slips – The signs where originally stuck using double sided tape – One sign was loose so I removed it, cleaned the sign and surface it was to be stuck too thoroughly with alcohol and stuck it back with industrial double sided sticky tape – 9.30 am just finished – 2nd customer walks in picks up his little piece of paper and decides to sit on the bench – right under the newly stuck sign (1 of 5!)
The sign comes off and slices his thumb – I’m at the other end of the shop finishing the last part of the job and wondering why that man is dancing around swearing and holding his hand – Then it dawns on me – O, Sh** thats my sign on the floor 😮 🙁 . Luckily the chap saw the funny side (in the end) and did’nt sue me – I now vowe not to fix any sign with tape or glue only (!) (!) – I wonder what the odds would be if I placed a bet on this happening (?) 🙄

Best of luck – Gary
