Note the holes where the broken circa 1970 doorbell was removed.
This is the supporting wall so it is particularly nasty as the house settled and then they jacked it up probably an inch or so at some point which resulted in:
Nasty stair step cracks all the way up and across. Previous owners skim coated the whole wall and surpise!? The cracks showed up again! So now I have to go through and gouge out their plaster and paint along the cracks so I don't end up with ridges along the wall. Then I slapped up a whole bunch of sticky mesh tape. This is just the bottom half of the wall. Can you see it in the photos?
The label on my tape is long gone but this is the same type and also from Menards so it probably is the exact same thing. Will it keep the cracks from reappearing? Maybe. Maybe not.
Other delightful things such as nail holes and what I thought were plastered over nails but turned out to be plastered over hot glue? dotted the walls to be repaired.
For the initial sanding I do some wet sanding which involves getting the plaster sandpaper wet. I would recommend a larger bucket if you have time to do more than a 3 ft section at a time oh, and also maybe covering up the vent as it still makes a mess but a majority of the damp plaster dust falls on the floor right below rather than all over me and surrounding furniture.
A side note: Don't dump the plaster water down the drain! It seems to me it would eventually clog up the drain? I always dump it outside as plaster is good for the grass so bonus there.
This is about as messy as I get since it all has to be scrubbed down before the baby wakes up and starts running around so I don't worry about the vent since it takes about 3 seconds to pop off and vacuum. This wall is starting to shape up! I think the plaster patches are an improvement over the cracks anyways!
