Anyone have any experience with the best ways to approach these 3 plaster scenarios. Small 1950's bungalow. I have structo-lite base coat here with me and can also use joint compound where drywall mud makes sense.
Pic 1: small kitchen wall. Previous owner glued laminate backslash to plaster wall...and it pulled off these 4 or 5 circles. Doesn't seem that enough is gone to demo through to the lath to redo from there. But maybe thats the only option.
Pic 3: Saw a strange plaster Crack by a back window and also some paint bubbling. Could have been before maybe an issue was fixed outside. Used a small knife and got the original and maybe second different coat of paint. But none of the wall is removed. So to me, floating drywall mud makes more sense.
