Hardie Panel installed on interior walls

[DanielP]

One problem to be aware of when smooth coating interior walls is with lighting; any lighting, up, down, or across, that is shining near parallel to the plane of the wall will accentuate any irregularities in, not only the surface material, but with any framing irregularities as well.

Textured walls are used, not only to save $ or hide mistakes, but as an architectural feature. I love our heavily textured walls. They look like Monstera leaves all over the room.
