Maximum torque. Amazing stuff. Will stick anything to anything

Thanks andy will give that a try

Did a load of kerb signs as a subcontract.

Take along a wire brush / drill attachment to clean up the kerb and try to work in DRY conditions – if not bring a gas torch to dry the kerb too.

My preferred adhesive is EVOSTIK ‘serious stuff’ – use it for years…nothing fell off yet.

for something so low down and fixed to concrete ide suggest using aluminium before composite. composite is a great product but it is relatively soft.

you also have to be careful on the adhesive you use because "some" cure at high temp levels causing dimples or distortion on the face. you cannot see it face on, but once the sun hits the sign viewed at an angle the dimples show up bad.

another alternative to an adhesive is threaded rods soldered to the rear of aluminium. works on same principle as a locator. drill holes, fill with a chemical fixing and leave. cures fast and its fixed solid.

also, BIGHead fixings can be used too. work a treat…

Kerb stones are relatively flat, but you should keep in mind you will need to have a pretty thick adhesive to self leave a rigid panel or you could have several areas fixed solid with one floating area.

also keep in mind how quickly the adhesive cures.
if the sign is fixed on the face of the kerb, you will need something to hold in place with the adhesive solidifies or you run the risk of the panel sliding.

I’m going to assume Luke is marking out parking bays in a private car park so the abuse level is likely to be low and comp takes a fair beating especially if backed off in concrete…the vinyl on the face is going to give way well before the comp or indeed aluminium.

Regarding soldering aluminium and steel rod. It takes a hell of a lot of direct heat (gas torch or mega iron) to solder them together properly with a good flow. I’d have though more of a risk of minor thermal dimpling from this. And big heads glued on – isn’t that reducing the surface area the adhesive has to work on to the diameter of a few fixings rather than the contact of the whole plate…and the additional work of drilling holes.

We cannot see the job in hand so i am not telling him what to do, i am giving him various fixing methods of how it could be done. it is up to him which he chooses.
My opinion of Aluminium over composite still stands though.

[Ruairi O'Boyle]

I agree with Rob on the aluminium. Composite will dinge and possibly even split much more easily, but you know your application.

[luke baker]

yeah they are just for a private car park, the customer wanted a cheap option so i suggested compisite.

thanks all of you
