Cloakroom tiling

[Ciscobloke01]

Hi, I'm looking to tile my downstairs cloakroom/toilet with floor to ceiling 45x45cm porcelain tiles. The walls are currently painted skimmed plasterboard.

I guess what I want to know is will the walls take the weight or am I in for trouble? I was thinking of stripper the paint off (of possible) and then keying all over before tiling or will this not be enough?

Thanks in advance

Mike

Hi Mike & welcome to TF. A 10mm Porcelain will weigh in at 23.88kg pm2 with a 3mm bed, 28.09kg pm2 with 6mm. 12mm Porcelain, 27.82kg pm2 3mm, 32.00kg pm2 6mm. Bare plasterboard will take 32kg pm2 & plaster skim will carry 20kg pm2. Painted isn't an option. Unfortunately, you will require to re-sheet.

Hay thx for the reply. Gutted the weight is over, I'm wondering g how much under the max weight the manufacturers go? They say 20kgm2 but wonder if it would take the 24kgm2 you mention? As for resheeting how easy/messy is it to remove drywall that has been dot dab fixed to internal block walls and stud walls? It's a small cloakroom, any ideas on tools I'd need and rough estimate on time to strip off ready for new boards?

It's not worth the chance to go over the weight. Can be quite messy if it's duplex but easy enough to remove. Sledge hammer & cold chisel will do if you don't own an SDS. Would take me just a morning to rip down a 16m2 bathroom so if you allow yourself a day to strip & prep & a day to re-sheet, you should be fine. If you have Duplex up now, replace like for like

Cheers, I'd of thought it's just normal plasterboard just being a downstairs toilet room? I'll be investing in a SDS drill to remove existing floor tiles in there so I reckon I get the toilet, sink and rad out the. Removed the plasterboard, wooden window cill etc and reboard using normal plasterboard again but without the skim coat meaning it should support upto 32kgm2 I think.

Just a thought. Could I get away with fixing 4mm Marmox with adhesive and anchors to the existing plasterboard and adhesive and screws to stud walls (if any) then tile off this to save the mess of removing the existing dot dab plasterboards and replacing with new?
