Hi,
Replacing kitchen backsplash tiles. Pulled the old tiles off and with it some of the surface.
The walls are made of sheetrock and coated with thin layer of something fairly hard. Looks almost like white paint, but it is not.
Any idea what I may be looking at? Would like to repair what came off with the tiles, with the same material. I know I could use mud, but this is in the kitchen and would like to make it more durable and seal better.
Regards,
