Sticking plastic to plastic

[Blair]

I wish to add a hook to a plastic surface to support a wall clock and I tried one of the suction type fixing. It worked for a while but eventually came off. I the added superglue to the surface but it failed to take. Any suggestions please Blair

Depends on whether you mind the plastic surface being damaged - airfix type glue would be a good bet, but if you remove the hook the plastic surface will be damaged. Window fitters tend to use a type of superglue. Evostick impact type of glue would be ok but it is worth roughening the plastic surface first - surround it with masking tape then sand the surface to fom a better key.

Thanks for your help. Unfortunately the hook is mounted on a suction cup plastic and I feel that pressing the suction cup to make it be in total contact could still be a problem Blair

Try Silicone Rubber sealant. Baz

I used Evostick and had success. Thanks Blair

I had a similar problem with a small rear view mirror in the car that I use to keep an eye on the rugrats. After a while it would fall off, so I used some clear (because it would be seen through the glass) very thin double sided sticky tape covering the whole suction cup surface and it is still hanging on!
