Number one son drafted me to help remodel a bathroom. It has a sloped ceiling over the tub and we need to put up some new backerboard over the existing gypsum wallboard. The rafters are on 24 inch centers and only two are positioned right -- one on the right edge, one 24 inches to the left -- for screwing in the 45 inch wide backerboard. Question -- can I use liquid nails to attach the left end and expect it to hold up once he affixes his tile?
TIA
