multiple rooms

[sapperdan]

Hi Peeps,
Just been to quote for a job where the floors are to be tiled with the same tile throughout ie 2 bedrooms , living room , kitchen and hall .All these rooms have gas fired underfloor heating already bedded in with concrete. The flat is a conventional building with each room leading into the hall.
I already have a plan of attack on this job ,but just would like a few suggestions from you more experience guys on the best practices on tieing in from each room to ensure matching and leveling remain consistent.
Square meterage is roughly 75 m2 .
Thanks in advance Danny

You need to allow for position of movement joints, at least at perimeters & between rooms. Room sizes would help.
Has under floor heating been switched on & run ?
What type of screed is it ?
Makesure is not anhydrite ! Needs 2 b treated diff than other screeds.

hello Tina,
Bedroom 1 is 3.65 * 3.74
bedroom 2 is 2.82 * 2.52
living room is 4.8 *3.65
kitchen is roughly 6msq
hall is roughly 6 msq

I`ve read the post on anhydrate screed and its preperation for tiling.
Just wondering if there is a visual tell that can distinguish this type of screed from normal concrete screeds ,the colour discription matches anhydrate.The surface has been boarded and has ridges.
Is anhydrate a self leveling screed with a smooth finnish.
Sorry if I seem green at this , but that probably is because I am . I have never come across anhydrates before. And if it is anhydrate what would you or anyone willing to give their view suggest. Other than pass it on to someone else lol.
Oh yes I previously said 75m2 in total there are a couple of other rooms missing from this list that are to be treated differently.

Firstly,ask customer who supplied screed, if lafarge, prob a gyvlon screed ( anhydrite ) but not always.
Also if it does not look like concrete then prob anhydrite.
Try scratching with key ! Does top layer scratch off ? Then prob anhydrite.
the ufh needs to be comissioned & run prior to tiling.
do not be scared if it is... proper prep & priming then easy peasy

Thanks Tina , that is invaluable info,
I will contact customer to find this info out. The screed has been laid since sept 2009 ,but the flat has lain empty since then with the heating being turned on frequently during the cold spell.
The customer who has just recently bought the flat has had a survey recently done.So this may have the info I need. I`m in Dumfries ,Customer in Newcastle. so plenty of phone calls lol.
If the floor is anhydrate , do you think without question ,an un coupling membrane or similar should be used . The Screed should not encounter any great volume of moisture as the entire floor has underfloor heating, but because of that heating system obviously it will be apt to greater heat movement or will a flexi suffice.
I will also contact the anhydrate vendor you previously mentioned , as obviously I need to find out more about this.
Thanks again Tina.:hurray:

Also just found this , I`ll post it here so I don`t lose the web address.

Un-coupling good but not alwayz necc
Depends on type of tiles you are laying, are there any cracks in screed ?


P.S, the bit about the key is to check for somethingcalled laitance, this is common in anhydrite screeds. Needs to be taken off before tiling.
Even screeds with low laitance usually have some !

Dan, as Tina already noted, you should place a soft joint between each room and around the perimter of each room. I'm assuming the hallway is outside of each room, so the soft joint could be placed under the door between the room and the hallway.

The bedrooms are close to square, and the living room is not square but is less than a ratio of 1.5/1.0 on the dimensions. There's no need for a soft joint in the field for these floors, unless the longest dimension of the living room is an issue because of the heated floor or if the room gets strong sunlight. Here in the the US, the TCNA standards tighten up when there is floor heat, and I bet the British Standards are the same.

Hallways almost always exceed 1.5/1.0 ratios and should have soft joints in the field, but the customer almost never wants to see them.

When faced with large inter room fixes one of you main problems can be marking out. That is you can mark out 1 room and it looks good but when following your lines other rooms can look out of wack.

As has been said an expansion at threshold can help in situations but often looks out of place .

We got into the practice of breaking large fixes at thresholds which allows each room to be treated seperately while including a feature.....

May be worth a thought............

A laser square is invaluable when doing multi rooms ...

Just to add Gyvlon LL ( low laitence) doesn't have any if correct consistency was used..i'e not overly wet when poured..

Search
​

Do a search in the bar above and there is loads of info on this screed...... ^^^

I agree there with you Tony

Wasnt on abou keeping square was on about rooms looking out of wack.

If you tile your kitchen and have to follow into a living room due to room shapes and wall angle you can generally only get one room looking bang on.

Beginning in the kitchen you should work off your eye line which is generally the plinth oposite the door, this can go in fine but that line may leave you with a narrow or angular cut in the lounge ye. Breaking your threasholds allows you to set each room so they all look as they should..............

I agree there with you Tony

Been doing it for years Doug and as we work with stone it can look pucka...........


Used same principle here where we had varying floor levels. Focal point will always take the eye off the ball..............

I have a house on the go currently and i have 500x500s to lay in kitchen and linking landing floors.its a 3 story building.ill be breaking at doors but keeping lines going i hope.its all in the lining out to get it done proper but as we all know a lot of rooms aren't square off each other! Builders eh? Lol
