11th July 2022 Do you glue or nail wainscoting? To create wainscoting you use both. Glue is applied on the back of the inlay mould lengths and glued to the wall where you will need to apply pressure for 10 seconds to the piece. If you need to move a piece of inlay mould after this you can but need to reapply 10 seconds of pressure. You then nail inlay mould pieces using short nails and fix nails on a slight angle to gain more holding power to the plaster while the glue dries. Intrim also has its own glue Intrim Intense Grip Adhesive available for purchase.
