expansion joints in granite floor tiles for area 300sqm

[archer]

Hi there,

i have recently been asked to tile an area of about 320sqm with granite floor tiles. the screed has not been layed yet and i was wondering at what intervals the expansion joints should be laid, wether they must match the saw or cold joints in the screed, i phoned the suppliers of the tiles and he suggested using a polymer grout as expansion. also would a normal cement based adhesive do the trick or would a flexible one be a safe option?

cheers

Expansion gaps vary depending on the architects mood :20: Some say 5 metres and others say 8. Is there an architect on the job that you could speak with?
Is this a ground floor that you are tiling?
A SPF would be advisable over normal rapid set.
What is the project? Is it going to have much traffic? if so how heavy?

appreciate the quick reply, its a ground floor room, and i think its going to be a function room, weddings discos etc? pardon my ignorance what does spf stand for?

cheers

Single part flexible. You can get expansion joints from schulter systems

Schluter Systems - Homepage - Schluter-Systems

Have you ever carried out a project on that scale in the past?

thanks, think i already knew that, been a slow day today. no i havent tackled anything this size before, i havent commited myself to anything yet, im just trying to learn about every single aspect of it and the solutions. i looked at the schulter website. was wondering if there was a knack to laying them having not done expansion joints before but i suppose everyone has to start somewhere? as long as its done correctly.

Thats a fairly big job for any tiler! What size are the tiles and how do they want them laid?

300by 300, and laid in a normal grid pattern, its not the size that worries me but getting the expansion joints right.

I would use the preformed schluter ones for a jobn that size m8.

Over 40 m2 area your should have expansion gaps every 5m if it's heavily used traffic area, schluter does brilliant expansion trim especially for that, if its 1 big area just divide area 320 m2 in 25m2 it will be 12 square sections, between sections should be shluter expansion trim
good luck
