Tile weight on various surfaces

[dingo]

Yip i'd 2nd this

absolutey correct . . as profesional we know more than the customer, a customer can sign whatever he wants, but it's not worth the paper it's writen on . .all that matters in court is when the prosecution says "so in your profesional opinion it was not safe to tile, why did you tile it" answering " because the customer told me to and signed a disclaimer" wont wash

Got a job with 300x300 travertine mosaics ( individual tiles are about 30mm ish each) . When i went round to quote last week i explained to customer that i was worried about the weight of tiles and the substrate.
The walls are plasterboard, skimmed and painted. I measured the tile sample they had and according to my measure they were 8mm thick, its only a small kitchen splashback, split into 0.8 sqm sections. I know i'll have to do something about the paint but do you think the walls will hold? I know 20kg per sqm is recommended max, 32kg on bare plasterboard. I'm off to CTD tomorrow to check if the total weights are on the tile box but just wanted some advice from you guys.
Bit concerned about ringing customer and saying she'll have to choose new tiles.....better than wall collapsing though!

You would probably get away with it, I feel. as they are mosaic on a sheet, there is a lot of "air" in the 300x300 sheet so your weight will be less. As it is a splashback, the likely hood of them falling off and hurting someone is small.

By all means check the weights given on the box or if not, just weigh a sheet and multiply it by 11, this will give you an indication.

Hi there,

I have recently had the same experience and this is what I found out at the time.

A 300 x 300 x 10mm sheet weighs approx 23.2kg and then there is the weight of the adhesive on top. I would be reluctant to fix those tiles without some prep done first. If you back up your comment with hard evidence your customer should see sense.

Good luck

Wheres that weight to surface ratio table cant seem to find it any where.
Cheers Lucius,

Its alright ive found it in my favourites

Hi
I am about to lay travertine onto plasterboard. The tiles are 406mm x 406mm, and weighs 4.85Kg each. I was told to allow upto 6kg/sqm for adhesive, does this sound like bunkem to those that know? As this would put me just over 35kg/Sqm.
Thanks.

 

[david campbell]

i was also told that addy and grout will weigh about 5kg per m2 ?????

 

[wetdec]

At 6kg/m2 thats a little over 3m2 out of a 20kg bag which contradicts the usage rate for powder on floors so is high.

Floors with powder we average 4.5m2 from 20kg (depending on substrate) On walls we woud use 3kg /m2 approx.

Given these I would say 4kg/m2 would be about the averge...............

I am working on Mapei's lightweight adhesives offer and wondered what fixers thought of the light weights on the market.

Do you use them?
Do you see an advantage in using them?

 

[david campbell]

never heard of them but it sounds like a really good idea as a lot of people are now using heavier tiles such as porcelain and travertine on walls and don't want the expense of re-sheeting to a product that can carry the weight more efficiently

 

[Spud]

ive used nanolight good adhesive but not worth the extra cost imo if you can price them right then great, is adsilex p10 a light weight ?as i have used this as well

 

[Fred]

Saw it in this months stone mag. Have not seen in the shops yet, but if its more money I won't use it.

 

[davy_G]

Im afraid im in the dark about this one, could someone enlighten me?

 

[hillhead]

Mapei showing its prowess yet again,good woman fiona,price comes into it a lot but i'm certain you have nothing to do with that.The light stuff is a definite advantage on heavy tiles on walls.

I'm alittle in the dark on this one aswell, but I'll take a stab at it :lol:

I "think" it is a product that goes further, but weighs less. I.E You get 5sqm from a 20KG bag, but with the lightweight stuff you get 7sqm from a 15KG Bag. If that makes any sense? :lol:

 

[faithhealer]

keep us posted Fiona, might help on those borderline weight issues

 

[DHTiling]

I think this is what mapei are on about..

Mapei ultralite S1

 

[andy-p]

ive used pcis nanolight and it claims a 15kg covers the same as a 25kg bag of normal gear, the advantage to me would seem to be less strain on the old back ...

Must admit never heard of it but read with interest

Hi All,

Just a quick question about how much floor tiles can hold in weight.

I am tiling my bathroom floor with standard 10mm ceramic tiles (300mm x 300mm). I will also be installing a stand alone cast iron column radiator that measures 30cm x 30cm x 50cm. The radiator stands on four legs and weighs approximatey 40kg.

Will the floor tiles be strong enough to hold this weight?


Regards

Chris

 

[theyomper]

provided they have been laid correctly...........solid bed not dot and dabbed.......you should have no problem

 

[Daz]

Chris,

I'm guessing you are at least 40kg in weight, I know I'm a lot more! Even with water in, if you've fixed the tiles correctly to a secure and solid substrate then you wont have an issue .

 

[doug boardley]

if you're thinking of using a standard ceramic, the glaze may not be durable enough for floor traffic imo, see if you can find out the PEI rating, 5 being the most durable:smilewinkgrin:

 

[Time's Ran Out]

That's an interesting point Doug - If they are selling it as a floor tile one would assume you can walk on it!
I don't think it is the cast iron legs of the radiator that is going to do the walking - as long as its not dragged over the floor surface and the tiles are solid bed fixed, even grade 1/2 pei are suitable for bathroom use.

John.

Thanks everyone for your response.

I will ensure all the floor tiles have a full covereage of adhesive - I believe I need to used an 8mm notched trowell for this -

I will ensure I don't drag the radiator when I install it to avoid damaging the tile surface.

Many thanks again.

Chris

For floors 10mm minimum or better still a Thick Bed/Solid Bed trowel.
