I hope that you can help me with my plaster problem.
My 60 year old house was built by a plasterer. The walls are 1 skim coat, 2 brown coats, over plaster board. Total thickness is up to 1 inch. The kitchen and bathroom walls have been covered with 1950's yellow and pink plastic 4" tiles.
I have removed the kitchen tiles during a remodel(new cabinets, appliances, opening oak floor, and removing tiles). The tiles left patches of old adhesive ramdomly over the open wall. Some plaster surface was removed.
I used a non flammable adhesive remover to remove the adhesive. The plaster now shows deep tile pattern marks(up to 1/16 inch deep). The squares are 4" on a side on the top half of the room. The bottom half are 12" squares. The surface now feels smoother, but the open plaster requires a leveling or skim coat.
I tried plaster of paris. I applied in thin runny paper thin coat. It just turned to dust and brushed off the apparent painted surface.
Now that I have a reasonable smooth surface(not smooth enough yet) what can I do to put a smooth surface on the plaster and be able to paint the surface?
Thanks for any help you can provide
