Has anyone here ever *roller textured* drywall using a
mixture of joint compound and paint?

I had a couple drywaller/finishers/handymen come out to bid
this job (floating my living room walls and ceiling) and neither
of them wanted to mess with it. One of the *pros* suggested
this technique w/ the mud and paint - assuming that I didn't want
to re-hang my sheetrock - and I'm just curious how well it holds up.

Is this something that I'm going to have to redo a couple years
down the road? Or will it stand the test of time?
