How to repair this wall for it to be ready to be painted on ?

[Karellu]

Hi, I removed the laundry tub and some wall tiles in my laundry. With my very limited knowledge, I think the plaster and drywall paper are damaged. I'm not sure if there is anything else.

  

 

 

 

What should I do ?

Thank you

Hi @Karellu,

What you've said is correct that there is damaged plaster, and the paper face of the gyprock has peeled off in sections. These are not particularly difficult things to fix, but if you had other plans in mind, fixing these issues before other steps might not be wise.

I'd need to understand what you're planning to do from here to offer the best advice possible.

Are you planning on having the taps removed? Are you planning on putting in a new laundry tub? Are you just looking to paint it, so it looks a bit nicer?

If you're removing the taps, you'd need to patch the plasterboard. Check out How to Fix a Hole in the Wall for some guidance.

For the areas where the paper has peeled away from the gyprock sheets, you'd need to skim-coat them with a topping compound such as this Gyprock Less Mess Topping Compound.

The corner also needs some work to get it back to perfect. You can use a Hyde Plasterboard Inside Corner Tool to apply the same topping compound to tidy it up.

If you can let me know some more details, I'll happily advise further.

Hi @JacobZ, thank you for your reply.

I'm not changing the taps and I plan to get a cabinet with a sink and put some splashback tiles. 

I filled the holes with plasterboard and I may have put too much because now the area is bumpy where I put the plaster (see photos)

Hi @Karellu,

You're on the right track. Sand any areas that are proud of the surrounding surface back so they are flush with the plsterboard. You can then add a very thin coat of plaster over the whole area so it blends seamlessly. For the areas where you'll be installing the splashback tiles it doesn't need to be perfect as it will be covered. It's just the exposed areas you should spend time on to achieve a flat and consistent surface.
