Hi firstly i am a plastering rendering amateur only hard walling up to this point.
Replaster bathroom wall.
Do your best to remove the damaged plaster.
Smear the plaster onto the wall starting with the bottom corner.
Patching a plastered wall is a great deal easier than re plastering it from scratch but often the job that needs to be done needs more extensive work.
3 walls are your standard house brick and the 4th is an internal wall made of black 35mm thick air brick nasty stuff but not an option to remove.
Because if the patches are large or extensive it simply isn t worth doing you ll never get a surface good enough to paint or wallpaper on.
At the top of your stroke slide the trowel over 2 3 inches 5 8cm then reverse the motion and bring it down again.
We are in the process of doing our bathroom because for the old plasters condition we have removed back to brick.
Use a drywall knife or other scraping tool to gently scrape away any peeling or soft.
You can also use a hair dryer or heat gun on low to speed up the process.
