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?
Not on your life.
Use 3M-5200 and let it cure 72 hours before you remove the bracing
holding the backerboard in place.
About $10/tube for 5200.
Home Depot has it in stock.
One tube should be enough for the entire board.
No need for fasteners.
BTW, after the 5200 cures out, don't expect to be able to remove it.
It is very unlikely that you'll get it stiff enough to handle the
tile, and all it takes is one little flex to pop it.
I'd drop the drywall and add framing members as necessary, then affix
the Wonderboard or Hardibacker to it, seal, and tile. Figure an extra
couple hours for that, but it's done right.
It's a great life...once you weaken.
