Tile Weights

[Mike Mike]

I seen last week on site, 20mm stone fixed to double layed plasterboard. The stone was 600x1200, finished height 1200mm. The glue behind them was around 10mm. Is this feasible with the 2xplasterboard and that height, or is it inevitable to have problems?

That's an interesting question. Gut reaction is "hell no, that's way too heavy, plasterboard is 32kg/m2 period, no matter how many sheets are screwed together, because it's the tensile strength of the paper to the gypsum that matters.

But gut reactions aren't always based on fact, or correct.

I think you should contact the manufacturer of the plasterboard and ask them, or the tile adhesive manufacturer. We double board sometimes here, but it is more to do with avoiding water vapour penetration to timber framed house core structures than trying to allow heavier tiles to be fixed.

doesn't help you much with costing

[Mr T]

Could I ask a favour... Could someone in the knowhow copy that table and list all the surfaces that will take the weight? Sorry if its a bugger it would really help me out

[Mr T]

lmao no worries matey could you inbox it me? just wanna look at your work

 

[Sean SML Tiling]

Are these the weights of using a 6mm trowel or is it 6mm of adhesive behind the tile once fixed? Sounds a stupid question I know.

 

[Mr T]

a 6mm trowel will give you a 6mm bed wont it mate?

 

[Sean SML Tiling]

Once the tile has been pushed in the bed goes from a 6mm to probably 3mm. So im asking a question that people might assume its a 6mm trowel when It could be the other way around.

 

[Mr T]

oh I didn't know that mate

 

[Mr T]

oh I know what u mean... my guess would be that its a 6mm trowel which gives a 6mm bed I doubt it would mean a 9mm trowel or a 12mm one.

 

[Ian]

A 6mm trowel will give a 3mm adhesive bed (roughly), when the ribs are compressed and a 10/12mm trowel will give a 6mm adhesive bed (again, roughly)

 

[Sean SML Tiling]

So im assuming with the weight list the 6mm bed is using a 10/12 trowel (roughly). Cheers bri.

 

[Ian]

You got it mate, those bed depths will be based on 6mm and 12mm trowels.

 

[Mr T]

sorry sm tiling my bad mate

 

[Sean SML Tiling]

Easy mistake. Just thought it was a question worth asking.

 

[Mr T]

sorted mate and yeh it obv was a cuz I would assumed otherwise haha
