    Question Repairing plaster walls

    My house was built in 1927 with plaster walls. For years the bedroom was covered in ugly paneling. My husband and I just removed the paneling and the four layers of wallpaper under the paneling. By the way, thanks for the tip about removing wallpaper! Most of the plaster is looking good but with little holes. The outside wall near the chimney has had water damage and the top layer of the plaster has come off in a few spots (1 1/2 feet in diameter) and is discolored in that area. The layer underneath seems fine. How can we repair the surface layer of plaster? I only see videos on how to repair it when it's down to the lath.

    If it were me i would use Master of Plaster to skim all the walls smooth.
    This product is the most user friendly.
    Also it is all lime based.
    Other productys that could be used are as follows.
    Variance Alto smooth this is an Acrylic finish plaster.
    American Clay has a plaster that is ok but watch were you use it due to moisture.
    Also you copuld use USG Diamond finish or **** Bond Kal coat finish.
    from all, of the above Master of Plaster is the only one that would be easy for a DIY job.

    For minor patching of plaster, I just use "hot mud" such as Durabond Easy Sand. This is a quick setting drywall compound that is easily sandable. It bonds well and does not schrink and crack. It does not need a bonding agent to feather it to the existing plaster. If down to the scratch coat, I like to slightly dampen the old scratch plaster before applying the DuraBond.

    Fortunately, I had access to a talented plasterer for more elaborate patching. They are getting harder and harder to find in this day of drywall.

    Not to hijack the thread, but I've got similar questions about this and I appreciate the input. Also, after years of painting and painting and painting plaster, it turns into a very brittle slick surface that isn't at all pleasant. Has anyone had success in sanding it smooth, or is there no way to sand through paint without damaging the finish plaster?

    Check some of the Acrylic veneer plaster.
    Like Variance and others these will go over existing painted surfaces.
    So all that you would to do is reskim the existing surface.
    Also check on Master of Plaster it will work and is very user friendly.
    American Clay has some very good products that will work as a skim coat.

    Waxmania,

    It sounds like your complaint is not the plaster itself, but the texture imparted by years of less than great paint jobs? If you are trying to get back to a really smooth surface, you can run a sander lightly over the walls to knock down high spots and then skim coat drywall mud over the entire surface. Sand the mud with a sanding block with 120 grit sanding screen attached and then prime with a good acrylic primer.
