Hi

Just need a bit of advice on a job I may be doing that I had a look at today. It was to replace some lower tiles in a shower unit but its not as simple as that. After the shower drain pipe leaked water had got into the substrate causing tiles to eventually come off.
Anyway the client decided to rip off the tiles effected and also the plasterboard underneath leaving a gaping hole of about a metre square on one wall from the floor up. The plasterboard was attached to the underlying concrete breeze blocks by dot and dab, and the ‘dots’ are still there!
Some drying out is still needed so he wont be getting back to me before it does, which gives me some time. He was planning to do it himself then had second thoughts.

The tiling itself isn’t the problem its dealing with the hole Im a tad worried about especially as its early days for me. If I cleaned up the edges of the existing plasterboard (more tiles will have to be taken off) and patched the hole with backer board (ie: Wedi board) obviously sealing all joints (plus tanking) would that be ok? Would I also be better off using the thicker board so I wouldn’t have to use so much adhesive (dot and dab) and there’d be less movement to make it easier to match up with the plasterboard?
Im assuming he’ll get other quotes so I wont be too upset if I don’t get it, but would like to know the best option.

Cheers

Personally I would do what you have suggested i.e. tidy up existing plasterboard then reboard and tank.

cut plasterboard square to fit big.hole....Silicon a line arond the opening as close to the hole as possible....push plasterbord up to Silicon...pull back off and the shape of hole will show itself in a Silicon line.Cut it less than space between silcone and hole,you can always fill if its a tad to small ...its a method of shape tracing but works well..Gaz
 
Thanks guys.
Sorting out shape of patch wont be too difficult, just wanted to make sure I was going in right direction to sort it out. Love the Silicon idea, will have to remember that one.

cheers

Also if the hole is fairly deep..ie. lots of dot&dab then use a couple of layers of board to build it out...then as the rest have said then tape up joints and tank....dave...
 
It is fairly deep which is why i thought id be better off using the thicker dimension board. As I seem to be going in the right direction Im alot happier if I get the job.
