We are working on a bathroom that was covered in vinyl wallpaper. The walls have been treated to remove the wall paper paste. Removing it left sections of the original Navaho White (mud color) paint and sections of bare plaster. The paint and plaster sections are very intermixed (dots, spots, measels and splotches of plaster amid the paint) and the paint layer is higher.
High enough to show up under any layer of paint.
The wife has been busy with some test panels to prove the adage that paint will cover but won’t hide irregular surfaces. She thinks it will – in four coats. Maybe five.
The paint is well adhered. We have been sanding with 60 grit, which knocks it down a bit but is not about to sand the paint even with the plaster in my lifetime. (On the boat – 1100 miles N. – is an 8″ grinder and foam pad that would sand the whole bathroom into dust with nice 36 g. disks. Anyone make 36g for 5″, 8 hole orbital sanders?)
What do you recommend in the way of a skim coat over paint/plaster, a full-wall spackle session or ???

Sand the walls a bit with 150 or 180 grit sand paper then apply a coat of PVA bonding adhesive (this is also known as concrete or cement bonding adhesive at the hardware store).
Once the PVA has gotten tacky apply a coat or two of EasySand90. Sand it when it's dry.
Then prime and paint to your heart's desire.

*The other option you do have to the high low issue is.. shoot the wall with texture and then paint it.not only is this about the same in cost but you will save alot of time and energy..

John, tried your email ([email protected]) address again. No joy again, same message from mailer demon. Send a correct address, Ive got a local source for you. Joe
*I don't think you need to apply a coat of PVA before using EasySand, since I understand that EasySand has a bonding agent in it. I would just spray a little water on the wall before applying the EasySand.

Jeff,
EasySand does have PVA in it already (they call it Vinyl Alcohol Polymer).
But EasySand doesn't have very much PVA in it. Deffinetly not enough to be going over paint with it.
Applying a coat (A thin even coat) will help to ensure that the EasySand adheres better. Especially to paint.
