Help!: Damaged plasterboard

[paul2024]

Hi everyone,
Just started my first job in a bathroom and removing the old tiles, trying to be as careful as i can but a few times part of the plasterboard has come away with the tile. It hasn't left any holes right through just craters. Can i just fill these in and tile over and if so how long will i have to leave the filler to dry for.

Thanks in advance.

What size tile are you doing the re-tile in..?

[doug boardley]

for the time taken trying to be careful with the plasterboard, I'd be inclined to rip it all out and start with fresh, clean plasterboard

490mm x 340mm Ceramic

Is it a stud wall or dot & dabbed board wall..?...

Stud wall will be just as easy to replace as doug has said and if it's a dabbed dry lined wall then maybe patching is easier..

I use one coat patch upplaster from wickes...dry's very quickly....prime when dry..

Thanks guys, i'll do that, being careful isn't my strong suit!

I'm no expert but wouldnt a bit of tiling adhesive into the "craters" and levelled off be ok ?

Yep...but depends how deep they are..as most bagged gear is only used to around 6mm deep...and you have to prime the craters as it's staright gypsum you will be putting the adhesive over.....

The patch up coat from wickes is gypsum based....

But yes adhesive can be used as well....Prime it..

if you end up stripping the old plasterboard off you may have to consider the disposal of the old board. check this link. http://www.tilersforums.co.uk/tiling...sterboard.html just in case it will affect you. good luck.

I suppose a deciding factor should be if the plasterboard can be repaired to a state where it's structural integrity is intact

Started ripping it out and found out it's dot and dab, will i have to put up studs to screw the plasterboard to or is dot and dab easy to do?

Here's a link DriLyner BASIC - Drywall masonry lining system Dot and dab is'nt difficult you just may need a little bit of planning. I would use 6 x 3 x 12.5mm boards, trying to get an 8 x 4 into an existing bathroom could be a bit of a struggle.

Ask any questions you may have and you will be answered

a sturdy straight edge to "whack" the boards and a good spirit level are the essential tools mate

Thanks guys, just dot and dabbed new plasterboard up. Well pleased thanks for all the help
