We just bought our first house (built in 1938), and the walls are plaster and lath.
We want to paint the interior, but some of the walls are a bit 'wavy' in spots. What is the best way to get the walls more level? Is it by sanding down the plaster in the spots sticking out? Or is it better to fill in the rest of the wall with more plaster?
Is this something that is necessary to do before we paint? Any input would be appreciated. This is our first house and we want to do things right.
Thanks so much!
