What glue should I use to stick it down?

Great question. It depends a little on what surface area we’re talking about. If it’s small and really high strength adhesion is required, a super glue such that is compatible with rubber such as our Weicon VA 8406 or VA 100 could be ideal. For larger areas, a spray on or contact adhesive may be the answer.

We keep saying may for a reason though. It all depends on what you need to stick it to and things like temperature, desired cure time and so forth. There’s a really great tool called the Weicon Adhesive Finder ( that may be able to assist though, of course, failing that don’t hesitate to let us know what you’re trying to achieve as we may be able to assist.

Does it come with an adhesive backing?

Not as standard no. That said, it can be arranged on special request.

Are other colours available?

Not of this particular grade we’re sorry.

Will you supply my order in one continuous length or multiple lengths?

We’ll always supply in as long a roll as possible to give you maximum versatility (nothing worse than being just a little too short). Maximum roll length for all thicknesses listed here is 10 metres so if you ordered 8 of one size, it would be supplied in a single roll.
