Walls – Can you glue backerboard to concrete then tile over

backsplashconcretetilewalls

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

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.
