Newbie needs help

[Dave G]

Hi all, its my first time so be gentle :-)

I need some advice about the best way to tile my kitchen floor, about 15sqm

Floor is an exsisting moisture resistant chipboard 18mm and i've screwed it down every300mm
I was gonna use nomoreply,them a ufh system, mat or wire I don't know yet. (suggestions would be good)
Then tile over using a rectangular 10mm black satin finish porceline tile in a brick bond pattern (hope thats the right term)

Advise I need is

What adhesive,grout to use do I need a primer/sealer and how big should the joints between the tiles be?
A step by step guide would be good

Any advice would be great
Thanks all and i've been looking through the forums for the past couple of days and had some real laughs LOL so thought I'd register.

Hi dave.....seen your intro in new members forum........

I would use a 12mm ply and then tile with a 2 part flexible adhesive ...if using BAL products you won't need to prime the ply......Screw the ply down every 300mm or so...prime the back of the ply and edges with BAL sbr before fixing...
Mapei do some very good adhesives as well but i am not that up on there products to say which to use.....

Just a question back to you before i advise grout etc......when you say satin porcelain...is it glazed or not....?..

As for grout use a flexible one suitable for porcelain and UFH ........

Cheers for the info Dave

Floor height may be a problem with 12mm ply, does the 12mm ply have any thermal value?

I wanted a thermal board under my ufh ( tight bugger I am :-) and thought about using a 10mm cement board similar to wickes aqua panel but the thermal version (if that makes sense LOL) but saw the nomoreply in a local tile merchants and thought it was ok..........is it not ?

As to wether the tiles are glazed or not........I dunno mate, will find out tho.

Many thanks

I,m not sure on the thermal properties of no-more ply.....I was more concerned on strengthening the floor abit as well......

you could use something like wedi or marmox insulation boards but they add no structural strength to the floor.....i don't think the 18mm chipboard will suffice alone on being strong enough....

[Dave G]

I thought all cement based boards had a good thermal value compared to normal ply???
If this in not the case then please excuse my ignorance on this subject as its all new to me Lol

Any thoughts on the type of UFH system to use, wire or the mat type ??

Cheers.

[Dave]

Not all cement boards are thermal boards.......

As for the ufh then loose or mat systems are good..just depends on the layout of the floor...the mat systems are great for large areas or areas that are straight forward...the loose cable is good for rooms with obstacles to get around.......both perform well.......

Ply dose actually have some thermal properties but not like thermal boards do......

You need to think about strengthening the floor....18mm is not really enough especially chipboard as it is not the most stable of substrates......

Cheers for the info Dave

My kitchen floor is 3m wide and has a supporting wall down the middle of the floor so my floor joists are only spanning 1.5m either side , hope that makes sense :-)

Well here we go,
I've got the nomoreply boards, glue and screws.

12m of UFH heating + stat and probe x 2 .

Tile adhesive is Ultra Pro Flex SP, grout is Ultra Flexi and a 10mm notched trowel oh and some SBR primer.

Hope the materials are ok, I went to my local tile shop(dunno if i'm allowed to print the name here)
Owner was very good and had some great advice also.

Only question left is..

I know that the nomoreply has to be put down opposite to how my 18mm mrc is but do I also lay the tiles opposite to the nomoreply??

Don't laugh, its not easy unless you know how to do it LOL :-)

[Dave]

Stagger the joints on the no-more ply and then tile.....you will be fine...

[Dave G]

Cheers dave

[Dave]

Don't forget the pics Dave....you know we love pics on the forums......

[Dave G]

How do I put picks on dave?


You only want a laugh lol

Hi Dave.

The supporting wall means you will require a movement joint along the line of that wall.
The wall acts like a fulcrum and has the potential to try to bend the tiles.
Contact Schluter Systems for the best advice on movement control joints.
