in some cases, its commonly used for that, but not always suitable

The floor/walls in question are concrete (floor), brick
(3 walls) and pebbledash (house wall) in a garage.

The concrete floor is bare, dusty concrete. The 3 brick walls are plain

pebbledash wall is as described - used to be the side of the house. Can
