Yep... I have a old home with sandstone walls. Often the raw plug will spin in the hole as the surrounding sandstone falls apart. Hence a loose raw plug.
I use Cynoacrylate (spelling may be out) like super glue but must be thin ( runny). I purchase mine from a model or hobby shop. Ask for Cyno thin. I squirt this into the hole and it penetrates the stone and makes the surrounding area hard. Then apply a small amount to the plug and re- insert it.. Always worked for me and have had nothing fall off the wall...
