Answer
It should never be used outdoors or in a situation where it would be exposed to water on a regular basis.

People often inquire as to whether MDF can be waterproofed.
Painting the MDF board is the only method to ensure that it is waterproof. Only if you apply moisture-resistant paint on the surface of the MDF board will it become more resistant to moisture. This sort of paint forms a more permanent waterproof coating on the MDF, which is why it is recommended.
The issue arises as to whether particle board may be utilised outdoors.
You should use particle board in these locations only if you fully seal it beforehand before laying tiles on the wall or painting it. Due to its inability to tolerate the wetness from rain or snow for an extended period of time, particle board should never be utilised in outdoor applications.
What exactly is exterior grade MDF?
Greenpanel Exterior Grade MDF Boards have been created to have better density and strength than standard MDF boards. They have a consistent thickness as well as a homogeneous structure.
