Tiling onto gypsum plasterboard direct tiling direct onto plasterboard without plaster skim is more stable.
Max tile weight on plaster walls.
This is equivalent to ceramictiles with a maximum thickness of 8mm plus adhesive or natural stonetiles with a maximum thickness of 7mm plus adhesive.
As a result this wall could support ceramic tiles that are around 8mm in thickness or stone tiles that are 7 mm in thickness.
Gypsum plaster walls with a good quality well adhered and dry plaster as the background for the tiles can support a maximum weight of 20kg m.
Around about now the plasterboard wall will be starting to show a little bit of stress.
You now have a superimposed weight of 60kg each fixing carrying about 22kg.
Walls with this well adhered and dry plaster can support a maximum weight of 20kg m.
If the wall has recently been plastered you should allow 4 weeks drying time before brushing with a stiff bristle brush and priming with dunlop tilers primer diluted 1 1 with water when using ready mixed or two neat coats when using cement based adhesives.
The maximum weight of tiling which can be supported by a dry well adhered plaster background is 20kg m.
Bear in mind that gypsum plaster has a maximum weight tolerance of 20kg m 2 and that includes the weight of the tile and the adhesive.
The maximum weight of tiles that can be supported by a dry and well adhered plaster background is approximately 20kg per m.
The maximum weight of tiling which can be supported by a dry well adhered plaster background is 20kg m.
This is equivalent to ceramic tiles with a maximum thickness of 8mm plus tile adhesive or natural stone tiles with a maximum thickness of 7mm plus tile adhesive.
So what does that mean for tile choices.
Well 20kg m is perfect for ceramic tiles of around 8mm maximum thickness plus the adhesive or natural stone tiles in 7mm maximum thickness and adhesive.
