large tiles plasterboard

ruddyuseless · 20 Dec 2006

I'm going to be tiling the bathroom using wall and floor tiles (Padova range from Topps). They are 45cm x 31cm and weigh 22kg/m2. Will I have a problem tiling onto plasterboard? The 3 walls around the bath are plasterboard and it will have a shower over. Also, the shop sold us Sealocrete PLA-GRIP tub adhesive. Will this be ok??? Starting to really worry now.....

the weight of tile is fine,plasterboard will take 32kg.
The tub gear is no good,id use Bal single part flexi, bagged adhesive.
You will need to prime before, Bal apd.Use thin bed solid bed trowel.
Shower area needs tanking also.
No worries

Thanks for that. The other walls (not plasterboard) have just been skimmed. Will they be ok, too and will I have to prime them?

Sorry to get in the middle of your tiff, but any answer for the 2nd part of my question ie on the plastered walls will I be ok and what do I prime them with? Cheers.

A skimmed wall will generally only be as good as the bond between the skim coat and whatever is under it and it is generally advised that a skimmed wall will only take 20kg/m2 combined weight of tile & adhesive.

The plaster will not need priming unless it is very highly polished in which case 50/50 BAL APD/water will do. with the added benifit of extending the open time of the adhesive.

Like sticky says tanking will make the shower walls (water)bomb proof, if any water should get through your grout the plasterboard will easily be damaged. and powdered adhesive is the way to go with large format tiles.
