So I need some advice on how to approach the smoothing of an inside wall - done in the 80s wavy style. Naturally I turn to mybroadband for help 
Caveat: my DIY skills/experience is minimal
Per attached, what would be the best way to smooth out the walls - completely remove plaster and replaster or skim coat? I would think that perhaps, due to the thickness/height of the waves, that skim coating could be a challenge.
Any advice appreciated!
