Layering up acrylic – is tensol suitable? Advice please?
If I want to build up 3 layers of acrylic on a sign front is Tensol a suitable cement?
Is it also possible to use double sided tape for where it won’t show through, ie to stick acrylic cut out letters to the panel? -

Tensol will do it no problem… (we have two types, i’m sure its Tensol 12 we use for acrylic) will check tomorrow.
Careful when sandwiching it as you don’t need much and its easy to over do it. if you apply too much or too near the perimeter of letters it will smear out the edges down sides and if you wipe it it will leave a dull mark in the acrylic. -
Thanks Rob.

Tensol 12 is the stuff you want….
Make sure you wear a mask unless you like getting dizzy!
I can smell it in my office when the boys are going crazy with it in the workshop!

I don’t use tensol myself but isn’t tensol 12 an interior adhesive? Sure when I did use it I was told I needed tensol 70. I use penloc from Eurobond for most of my acrylic bonding.

Chloroform if you can get it…and glass syringes / all metal needles.
Place one piece of material over the other and use capillary action to draw the solvent in…works an absolute treat.
Tensol 12 (the liquid one?) similar properties to above although not rated for exterior for some reason does very well.
Although using a ‘loaded’ paintbrush to flow the glue in from the edges also works – just not as well as the syringe.
Leaves no evidence of glue either as it just evaporates once it’s gently melted the surfaces together.
Surfaces must be very flat & very, very clean.

For an outdoor sign is a thin clear Very High Bond Tape suitable?
what would be the advantages of a cement bond over tape?

There is also Fusion cement which I recently bought online, as I can’t get it here in Belfast. It is probably the best acrylic cement I have ever used. It’s water thin so you will need a syringe with a 25 gauge tip. This stuff absolutely welds acrylic together.
In the states we used Weld on cement but apparently they don’t import it in large quantities.
There is also a thicker fusion to go around letter letter edges ect when doing perpendicular joints.

Spoken to the guys at Indasol and they reckon for outdoor signs to use UHB tape rather than tensol. They say that adding layers of acrylic outdoors the different layers may expand & contract at different amounts and that there would be more give with tape and the bond will be well strong enough. Think this will be the way I go as easier to set up & build.
Thanks for everyone that replied
