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?

    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.

  • Thanks Bryan’s-I can’t see the concrete wall to know if there are cracks etc.

  • 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.

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.+
