Slate tiles too heavy for plasterboard wall?

You would be just over the limit, plaster board (not skimmed) will take 32kg per m2,so with your tiles and 4kg for adhesive & grout making that 33 kg,to be honest it not much over so as long as the boards are well fixed I can not see a problem,but you could remove the board and replace with tile backer board taking you to 40 kg.

hi , when applying natural heavy material to walls on a plaster board surface it is taken into consideration the weight of tiles being fixed on top of each other . depending on the size of the area to be tiled work around the room a course at a time with a rapid adhesive then start a new course where you 1st started by then then your 1st row of tiles would have set ,if the erea is fully tiled a qualified tiler would fix a certain amount then come back to complete on the second day . its a bit like building a high brick wall its done in stages to allow to dry .

Depends how thick/heavy/size and if on dry lined plasterboard dod & dab on solid wall or nailed/screwed to timber studding/frame/partition .jf

If it was me I would plywood the area and screw every joint then I know it's safe

Hi the maximum weight limit for tiling direct on to plasterboard without skim is 32kg per sqr mtr ,using stone or in your case slate maximum thickness of 10 mm, this includes adhesive. I had this problem with a bathroom I tiled with stone tiles , the only solution was to cut out the plasterboard and install tile backerboard with bolts to the original brickwork ,or you can use batons to screw boards too. Tile backerboard increases the weight limit allowed considerbrerly. So my advice would to not take the risk do it right first time ,or change slate tiles to ceramic that look like slate with less weight. Regard Stephen.

no the weight should'nt be too heavy, i'd recommend plastering the plasterboard first though to give the tile adhesive a better key

yes it will put strain on the wall with that amount of weight per m2

Hi there, Plasterboard will allow you 32kg per square metre on the walls, hope that helps.

As always A G Fright advice is spot on.
