hi i was thinking of adding corkboard wall lining (the kind you find in rolls) for sound dampening and isloation. Being I dont really like the color of cork or the texture and wanted to paint, can I put that cork board as an underlay and use wall smoother paste on top(like th kind you put on plaster walls to smooth it out?)

My walls are currently plaster with some damp marks - but the damp issues have been fixed.

Could anyone see problems with what I am thinking of? Cork should provide moisture resistance naturally but i am not sure if putting smoother on will cause an issues.

Much thanks!
