Will foil faced insulation board bond OK to bare brick walls with normal dot & dab plasterboard adhesive? I'm renovating a small bathroom. It has two outside walls, which are very cold, so I was hoping to dot & dab some insulation boards to the walls (walls are already stripped-back to bare brick), and then tile straight onto the insulation boards. I've got some spare 22mm "Kingspan" type board, which should be ideal, however it is foil-faced on both sides, so I'm not sure how well it's going to stick to the wall, and indeed how well the tiles will stick to it. I was thinking of painting on a slurry of adhesive onto the foil faces first if necessary. Is this likely to be succesful?
Similary, the ceiling needs reboarding, and I could use more of these insulation boards for that, which I can screw up to the rafters, but again, would the foil face take a skim of plaster OK? (again, with a slurry of adhesive or some primer if necessary)?
Looking forward to your thoughts. Thanks.
