Hi friends, my partner and I have been struggling with the vj panelling sheets. We sanded and cleaned the wall beforehand. Then used Selleys liquid nails to adhere it to the wall. We tried to nail it to the wall but the sheets continually pulled away from the wall, pulling up the nails as well. We stood and used our body weight for 2 hours to push it flat and when we finally gave up it had still only dried in two corners with the centre completely unable to be pushed flush. What are we doing wrong? Feeling defeated about continuing the project as this was only one sheet out of several.
