price

[piehead]

Customer looking for a price to fit 62m2 600mm by 600mm porcelain tiles, they are prepping timber floor with 12mm ply also looking for aprice for flexy addy

[dagger]

12mm ply, large format tiles?

oohh, thats not a good start!

[Dave]

We like all pricing to take place in the tilers arms.....

Get yourself in there and i can move this thread for you...


Where's the door to the Tilers Forums Arms?

[piehead]

why not!

[doug boardley]

why not why piehead? we don't discuss pricing in the public eye as it can lead to conflict between tilers and customers. As we all know, we price jobs depending on differing circumstances that the public don't always appreciate

[mags]

think he meant why not 12mm ply for large tiles and I also wonder?

[doug boardley]

it'll be ok if it's 12mm overply, c'mon piehead, what were you "why not" ing at?

[dagger]

i am no fan of BStands, however 18mm is a minimum overboarding (according to them).

that said if it was glued (polyeurothane) and screwed @ 200mm centres and i could use a latex additive i would be a happy bunny, failing that i would want 18mm and a good quality spf.

after the cost of glueing and screwing and latex additive, it would be cheaper to 18mm!

IMO.

I was why notting at the 12mm ply answer not the pricing reply

Where have you been since November 2007?
There will be members who have missed you!
Have you seen the developments in floor coverings and adhesive types over the last couple of years - Amazing!
For flexi adhesive have a look at the Mapei Range of products - there will be something very competitively priced in there for your project.

Good Luck - 62sq mts!!!! Lot of weight for timber - check the joist sizes.

am i wrong John?

because even with s1/s2 standard adhesives, my prompt would mean a minimum over 12mm!

maybe, not even aimed at me?

[Oli]

I think 12mm is fine, its what i would use, yes BS says 15, but you cant buy 15mm so you'd have to use 18mm, I will put my hands up and say i've never used 18mm ply, its hard enough explaining away 12mm let alone twice that plus addy and tile thickness.

That's interesting question.
Every time, when I tile 20mm marble on wooden floor, I wonder, how much weight can joisties take?

From my calculation, 20mm marble + ply + existing boards + adhesive, there is something between 80-100kg per sqm.

Does anyone know how much weight can actually joisties take?

[diamondtiling]

Joist maximum weights?? Big Daddy and Giant Haystacks standing nose to nose is a no no but Ronnie Corbett and Willy Carr would be a go go. Hope that not too technical as i am trying to give out good advice.

depends on depth x width x span as to it's load bearing capacity

[doug boardley]

piehead, just to clarify, is the floor just 12mm onto joists, or is it a 12mm overboard on an existing floor?

[piehead]

Sorry about the delay Doug, the 12mm ply is being layed over an existing timber floor

[garretridge]

i just tile and go not my fault the customer is 40 stone and he ate to many pies!

The weight of the 20mm marble in the room with 30sqm is almost 3 tons.
That's about the weight of the adult elephant, sitting 24/24 in one room.

[diamondtiling]

But not in one area, its spread all over, still has to be checked though

[doug boardley]

I agree Dom

[milan11]

I agree too.
But checked how?

[doug boardley]

take an existing board up and crane your neck round I'd say

[doug boardley]

most joists would bear the weight though, after all a washing machine will weigh more per metre square than 20mm stone, imo

[milan11]

Well, I'm about the size of junior elephant and my weight isn't spread out all over the floor.
Would you still want me to do that?

[doug boardley]

just recapped on the op and it's porcelain! Where's the problem? it doesn't really matter if it's 600 x 600 a tile isn't gonna cover less space than a person

[milan11]

OK, boss.

[milan11]

And how about me, pulling washing machine on 20mm marble floor sitting on the joisties?

[Stan001]

Well guys – here I reveal the magic number! i.e. how much weight your floor (joists plus floor stuff) should hold if its built to spec.
A tiny bit about me … I’m an NHBC registered builder. This means my house(s) are built to NHBC spec. They ref to latest BS specs. They have a bible called ‘NHBC standards’ with all the specs in / pointers to specs in it. (about £90 for you, I get it for free with my £1700 membership ). Simplest way is if I quote straight from ‘the book’ for you (to relieve your worries – assuming your house is built to spec.) …

QUOTE

Upper Floor Design
Section 6.4-D3. Upper floors shall be designed to support and transmit loads safely to the supporting structure without undue deflection.

Items to be taken into account include:
·Dead and Imposed loads.
·The dead loads include the weight of the following:
·Floor structure, decking and finishes.
·Ceiling and applied finishes.
·Wall and partitions supported by the floor.
·Permanent fixtures such as boilers, water tanks etc.

Imposed loads are the variable loads imposed when the building is in use. They include the weight of furniture and people. BS 6399-1 recommends an imposed loading allowance of 1.5kN/m squared for self contained dwellings.

Where the design includes communal areas serving flats or maisonettes refer to BS 6399-1 for recommended imposed loads.

UNQUOTE

.. Stan's summary: if your house has been built to spec (and yes I do know the joist sizes plus pad support lengths etc. but that’s a 1 hour typing session – even for me) then the weight of your floor covering (all that 25mm ply, all that nice heavy Mapei muck, and all that trav lovingly carved out of some distant mountain) has all been taken into account. Then – on top of that you can happily put stuff on the floor that imposes a force of 1.5kN/m2. So carry on eating pies or stamping on the floor when the kids play their Xbox whatsit too loud. I had a waterbed upstairs in a house once – it weighed 1.5tonne! eeek – we thought one day that that’s exactly the same weight as a Landrover we had at the time. Like having a Landrover parked in the bedroom!

Hope that helps. ... Stan
