What kind of drywall is this?

[03mustangdude]

Tore down fireplace mantel since it was old and looked horrible. Am going to put a wall of tile up with mosaic down middle.

Here is what the wall looks like after teardown. Drywall looks pinkish underneath regular drywall.



Any idea what it is and also if I should replace the whole section above fireplace or just repair it sand and make sure its good before tiling?

looks like regular gypsum board to me?

edit: actually that may be fire retardant drywall. makes sense that it is surrounding your fire place.

never seen it before so maybe fire retardant stuff. I know gypsum you can repair, can you repair the fire retardant ones?

IIRC, the pink is fire rated.

I wouldn't risk it, unless the mud you're using is also fire rated.

Dude just recently posted about his fireplace having a crack in it and catching the walls and subsequently his house on fire.. not worth the few dollars/minutes you'll save IMO

Based on my reading regular drywall repair can be used to make repairs as long as drywall has not been punctured into fireplace area. It has not. Should I repair it this way or any other suggestion?

Good point off to lowes to get fire rated one.

Almost all drywall you buy at the store is TypeX which is fire rated. That looks like fire rated like everyone else said

It's usually the "paper" on the outside that's different, not the mud or gypsum itself.

Used a piece of hardiboard I had left over that's rated for moisture or whatever. Didn't tear everything out just cleaned it up and made it level to the wall for the tile to go on.
