Flush previously tiled wall

Hi All.

I am looking at flushing off a small section of wall that was previously tiled (see picture attached).

As you will see, there is still adhesive attached to the wall. Where the adhesive was removed, the brown cardboard is left behind.

How would I go about flushing off this section of wall so it can be painted?

Thanks,
Robbie

2 ways i can think of off the top of my head
1 get a scraper and scrap off the rubbish so there are no lumps stocking out and then fill and paint
2 cut out the section and replace with a new piece of gyprock and finish.

I'd give no1 a shot first and see how it goes. Depends what's there and your skills

 

Yep. Just scrape off the adhesive - doesn't matter if the paper comes off, too. Then just plaster and sand. Small tubs of mixed topcoat are cheap. A broad knife will help, as will one of those flat sander things for plaster - the ones with the mesh. No idea what they are called.

 

Angle grinder with very course grit sanding disc. A gigantic vacuum cleaner and dust mask. (This is what they were designed to do - grind).
