Want to know if you can glue backerboard to interior concrete wall for kitchen backsplash. Can’t drill as it’s a condo concrete wall. Concerned that tiles will shift as concrete wall shifts. Thanks

  • Does the concrete wall have cracks in it or show any current signs of movement anywhere? – brhans Feb 19 at 19:50

    If the concrete wall shifts I think you're going to have bigger concerns than having a few tiles shifted. Plus any movement in the concrete will also move backer board that is glued to the concrete, thus moving the tiles right along with it. – FreeMan Feb 19 at 19:53
  • Thanks Bryan’s-I can’t see the concrete wall to know if there are cracks etc. – Joe Feb 19 at 21:23
  • Thanks FreeMan- it’s a concrete slab. Concern is that if there is shifting tiles on backsplash have nowhere to go but out and off. – Joe Feb 19 at 21:24

Yes you can glue the backer to the wall. No matter what you do if the wall shifts there will be issues. Most the time if there is concrete I do not use backer unless there will be a large difference in surface height.

    If you go the backer board route, use a good construction adhesive.+ – JACK Feb 19 at 22:29
