All I'm trying to do is figure out the heighth of the platform I will need to build to install a new shower stall. Oh and Marlin, I said that a hole was not an option for many reasons. Number one on that list is not wanting to turn a $3,000 job into a $30,000 job.
In brief: Generally.. As far as the filling itself goes, you can eat right away with tooth colored composite fillings, but should wait at least one hour with amalgam (silver) fillings. It's always best you ask your own dentist as this can vary somewhat based upon the size and location of the filling.
A week or more really isn't necessary IMO. The shortest time IMO to leave it would be 5 days to allow the primer to gas and harden before any top coats go on. If you use DupliColor primer, you can wet sand after 30mins, colorcoat within the hour. Providing you don't have to do any extra body work after priming. it depends, I used automotive primer and waited about 3-5 days or until the smell is gone. Once the smell is gone then I know it has harden up really good.
