What type of wall surfaces can I stick wainscoting to?

The Intrim Intensive Grip Adhesive will stick to all surfaces – plaster, timber, brick or render. There does HAVE to be paint on the surfaces you are sticking to, and that must be in good condition (ie no flaking or cracking). The bond is only as good as the surface it is glued to – so if the surface is flaky paint, then it will not adhere well to the wall. If you’re worried about bonding to your surface, you may like to use masking tape to hold the inlay mould to the wall surface in some spots while the glue is curing. This may help when applying to an uneven surface, like brickwork.
