gluing velcro to rubber?

[jkn]

Hi all I have been trying to hold a rubber-backed carpet mat in place on our diner carpet. The only thing that has worked at all well so far is strips lf wide, self-adhesive velcro, with the 'hook' side stuck to the underside of the mat, and allowed to grip into the fibres of the carpet below.

Now however, the Velcro glue is slipping, causing the velcro to come off the mat.

Any suggestions as to a similar kind of glue to the velcro self- adhesive backing that I might try to make this more permanent?

Thanks Jon N

solvent based contact..spary carpet glue is really good..ask local carpet sellers/fitters

Also, consider the type of rubber you are trying to bond to. Silicon rubber requires a silicon glue.

non silican rubber requires an adeasives that the NP quotes.

Thanks, I've picked up a can and will give it a go once I've got rid of all the old sticky velcro glue (IPA seems to be working...).

update:

After a week or so of 'good gripping' with carpet spray glue. the velcro is sliding off the mat in a similar way to before. The adhesive still seems sticky. Have I eg. put it on too thickly? or any other suggestions?

Thanks, J^n

Evostick Serious Glue. You'll need to clamp (or weight) the velcro to the carpet for 24 hours before it cures properly. But it's very much stronger than a contact adhesive - and works on more materials too.

Hi Dave

Interesting - I have a small tube of that but hadn't thought of using it on rubber.

Thanks J^n

I've found it one of the best general purpose glues - works on anything Evostick contact will - and many more besides. But as I said it needs a day to set properly which will put some off.

FYI, after a week or so it looks like the Evostick Serious glue has done the trick. Thanks for the suggestion, Dave.

For those who don't know this glue, it (appears to be) a slow-setting, flexible, cyanoacrylate glue. Comes in small-ish tubes at 3 or 4 quid a pop in the larger sheds. I believe it is also suitable for use at low temperatures (below freezing).

Excellent. Glad to be of service.

I first used it to glue 'chrome' plated flexible trim strip to the plastic side mouldings on my old car - the original 'chrome' had failed, and new ones weren't available. Glueing soft plastic to soft plastic is one of those things most general purpose glues barf at, but it worked a treat. Then found it worked well for fixing velcro strip to a rubber block which was in turn glued to painted steel - to hold the rear part of the headlining former in place, but to allow removal.

It is pricey, but I don't mind paying more for something which works.
