My biggest tiling job yet

[One Day]

Carl, you shouldn't be taking on this job, get a pro in.

I took plenty of jobs on in my first few years which you would have said the same about! I did my research, much like Carl is doing here, asked the right questions and did a proper job.
I'd rather see someone like this tackle the job, who cares enough to ask questions, than a 'professional' know it all!

you have read the post presentation of carl?
It is not a beginner

It's been laid since the end of last November so I would assume 50mm drying at 1mm per day it would be more than dry enough. Roughly twice as long as recommended. I will make the suggestion tomorrow when I get to work if you think it should still be checked, but I think they may be expecting me to start it. Again, will it be OK to split it into 4 sections with expansion joints?

so a unheated room?
its not 1mm a day for this type of screed. It's 1mm for the first x mm and .5 mm per day after that at a curtain temp. What's it the the garage over the winter 5• ?

expansion joint is way down the list of questions to be asked

 

[Carl Haynes]

Thank you Impish. I'm beginning to wonder why I even bothered asking questions in the first place.
Julian, the garage has been closed off and industrial heaters left on a low setting for most of the winter.
No I'm not a complete novice and I did ask for advice in layman's terms.
Localtiler was being helpful and now tells me I shouldn't be doing it.
Don't know whether I'm coming or going now.

tiled a kitchen floor with simlar floor make up the guy put a large island with huge granite work surface on it. got a call from the builder 4 mths later as there was several cracks in the tiles running from were the island was sited .i proved that the weight of the island had caused the floor to subside by 8 to 10 mm in the centre of the room.
if you take on this project i would ask for a disclaimer

sorry Carl, not trying to confuse you, i can just see you cracking on and tiling it without the right information and preperation. what is the screed? That is the first and most important question.

 

[Just Rizzle]

tiling can be pretty straight forward at times it can also bite you if you dont cover your self, ajax-is probably right on his calculations but if the kingspan is on a uneven substraight or is over a void then thats were the pressures are going to create problems when the cars move over it weve all seen brick paved drives with car tramlines in them.

the screed isnt the problem its the king span and the sub floor were the pressures are going to be

so you were help responsible for the tile failure then Ray? Yes?

 

[Carl Haynes]

Localtiler, I should be able to get that info tomorrow.
Ray, the sub floor is 6" reinforced concrete and laser levelled and the kingspan is tightly packed in over a damp proof membrane with expansion foam all around the edge. Fairly confident there are no voids but I guess you never know. Having said that, if there are voids isn't it a bit late to deal with them?

 

[One Day]

If any tiles were to crack and you had solid bedded them, then it's not your fault! I'd take it on.

 

[J Sid]

as above, take it on but just tick of yours check list at every stage

I'm not kno

Ajax. I was starting to get disheartened about this job until you came along. I can't really get away from doing this job as the guy is one of my bosses. I feel a bit more comfortable after your comments but what about expansion joints in the tiles. Could I get away with tiling it in four sections and would I need a solid bed of adhesive or maybe use a wall trowel notched to10mm deep. Cheers for your input. In fact thanks to everyone who's commented.

knowlegible on trowel size to comment but I would have thought trowel addys on the floor and back butter the tile. In terms of movement joints you should follow the standards which from memory is max bay length 8m max size 40m2. Are you using uncoupling. When doing car showrooms tilers often do so.

they tried to put it on me. we took a tile up and running throught the screed was a great big crack and the floor had dropped 10 mmto the side of the island .
we solved the issue by marking out were the legs of the units stood taking out the island and core drilling 70mm holes were the legs stood, so releasing the pressures that the island had created then putting the island back on to the areas drilled were we replaced the king span with 120mm concrete blocks. core drilled out we then replaced the cracked tiles and have had no call backs since that was about 12 yrs ago

Aston's are front end heavy so it'd be more like .65 on the front and .35 on the rear maybe lol

I wouldn't know...they're above my pay grade
