There’s different ways of repairing walls, quick easy way for you is to scrape the crack or hole and fill it full of plaster, then sand it down and then prime it and paint it. This is probably the easiest way and most people do it. This way but if you have a continually cracking ceiling or wall over time it will crack again. The best way to repair a crack or a hole is also use some drywall tape or use some fiber tape to secure the repair from hairline cracks in the future.
The paper tape and the fiber tape does have a certain thickness to them and when you cover them with plaster it will give them further thickness. To properly cover these tapes up you need at least two coats of plaster. The first coat is your initial coat to secure the tape to the wall over the crack or hole and the second plastering will feather out the repair to the rest of the wall getting rid of any hump from the tape. When you’re sanding your drywall plaster repair I generally use a flat pad pole sander to give me an even sanding over the wall leveling any hump left by the plaster.
How to stucco over a ceiling drywall repair or a drywall crack repair? You still have to do the same procedure as you would if you want to paint it because the wall repair patch or the ceiling drywall repair still would have a hump that the stucco will follow. Of course the stucco will cover insignificant bumps or humps but will not hide blatantly large bump. Especially so if the whole wall or ceiling is totally flat except for this one bump.
Water damage repair should also be sealed with stain sealer in a large radius of the affected area to ensure that the stain will not bleed through the plaster ceiling drywall repair. I usually spray or role stain blocker on the area prior to performing the repair.
Bathroom wall repair can be caused by a slew of things but mostly humidity again “water damage”. Any water damage repair should be sealed with stain sealer prior to plastering any drywall crack repairs or whole repairs should be very carefully smoothed out and finished off because of the close proximity to the damage making it more obvious and visible. More attention after he paid for detail in the washroom for two reasons. The second reason is you are using a shinier paint most probably a kitchen bathroom paint and also you have more room lighting.
