This is likely to be a rather simplistic question but we have an indoor wall, most likely put in after the property was initially built. I have attempted to put up some hooks to hang some of our stuff up and save some space but I seem to either have a lot of really loose wall where the screws don't grip and then there is finally a bit if wall that seems to be extremely solid and really hard to drill into. What is the solution to getting some hooks into a wall like this? Thank you
