Gluing Vinyl & Other Slippery Plastics

Almost all high quality plastics that are sold for
the kitchen or bath are chemically formulated
to slough off dirt, grease, or anything sticky.

The other day I purchased a neoprene floor mat.
You've probably seen them. They have a medium
density white neoprene backing, about 1/2" thick.
A thin layer of tacky vinyl is bonded to one side.
They're usually placed on the floor in front of a
kitchen sink.

I want to bond a smooth piece of vinyl or fabric to
the tacky vinyl on the mat. This may seem simple,
but it definitely is not!

I wiped the mat down with copious amounts of acetone
to break down any surface resistance or coatings. I sliced
4" square sections from the mat and attempted to bond
different types of vinyl and fabric using contact adesive.
I tried the spray-on type as well as the traditional stuff
from a quart can.

Letting the contact cement air dry, or joining the two
sections when they are still damp makes no difference.
I've tried using a roller or compressing the sections with
a board and some weights. The bond is always lousy.

There may be special adhesives available for these
types of plastics. They're certainly not for sale at Home
Depot or Lowes. Auto stores sell spray adhesives, but
they're similar to the stuff you can buy at home centers.

Any suggestions would be appreciated.

I'd probably use regular "GOOP" adhesive, but don't expect it to prevent you pulling the pieces apart. It will prob work fine to prevent the two pieces from separating if something was sliding across them (is that clear? Hard to describe..).

Well, I've used Goop adhesives extensively. They will
bond things other silicone products won't.

The very thick and lumpy properties of Goop would make
it a poor choice if you want a smooth, even surface. I
suppose you could try thinning it out and applying it with
a brush or roller. I might give it a try.
