That's what I did. But new layer of vinyl then carpet. If you completely cover area you plan to drill with masking tape, it makes removing the expanded resin over flow a lot easierQuestion if your not bothered about the vinyl could you drill straight through ? Was thinking will just put carpet on top ?
Us as well two doses of delamination at once how unfairOK we have had useful proper responses..
I got totally delaminated on New Year's Eve !
If you drill and glue it put a bit of tape around the drill bit at the depth you want for visual reference or buy some laminate flooring and cover it with that - engineered laminate would be a lot stronger though
