I currently have 1/2 drywall on my wall sepating the garage, which is now an accesory apartment. The house was built in 1975. Code says it must be 5/8. It is not possible to take everthing down to add more drywall. Is there another way to increase the fire rating, by either a product I paint on or spray on?
I am getting ready for an inspection, just looking at other options I can run by the inspector if he doesn't like what I have. They tell me they are trying to work with me to get this apartment passed and legal. Both sides of the wall in question have 1/2 inch drywall.
