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 ........

[Dave G]

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

[Dave]

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......

[Dave G]

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.

[Dave G]

what???????
sorry I don't understand

[bigneil]

UFH, to my mind is under floor heating, in that there is pipework laced through a concrete floor? if you are talking about under tile heating like 'Warm up' or simelar then you will deffinately need a thermal board of some sort, so that you don't loose all your heat down the way. but as dave has already said, these boards don't ad any structural strength to the chip board. So i personally would plywood, then thermal board, then put down the under tile heating, and then screed over it with a flexible self leveling compound in order to cover the wires/mat and create a flat surface to tile onto using a flexible adhesive like BAL fastflex or ARDEX 7001.
The draw back being that your final floor is gonna be raised a fair bit. you could maybe skip the plywood layer depending how strong the existing floor is.
But don't take my word for it, other more senior members may wish to expand or improve on the advice i have offered.
good luck

the no more ply and ultra combination will be more than adequate mate. i am using the same combination tomorrow except im using 9mm no more ply. you better work fast with the ultra as it sets faster than any other addy imo.

[whitebeam]

You want to try Bisem spf white 15 minutes

[wayne]

mixed some ultra up yesterday walked up two flights of stairs into the loft and it had nearly gone off! mosaic fix went off in a few hours it was that warm

[Dave]

How do I put picks on dave?

You can make an album in your profile page......just add them to your album with the browse feature straight from your pc......

[Dave G]

Thanks for the advice guys.

Well its too late now lol

Got the nomoreply down, glued ,screwed and where the bit of concrete pad is I used the ultra.

So just need to seal it all with the nice smelling stuff:-) and then its mat time lol

I've got a little bit of a kick where the edge of the concrete meets my chipboard floor, but thats life and i'm sure that i'll get some of it out when tiling.

This was the first time i've ever used the nomoreply and I found it ok but the screws were a pain so I ended up pre drilling with a tiny masonry bit first, then it was ok.

Glue everywhere, anyone got any ideas how to get it of your hands LOL

Oh and dave I got some pics mate

[Dave]

I've got a little bit of a kick where the edge of the concrete meets my chipboard floor, but thats life and i'm sure that i'll get some of it out when tiling.

Are you also tiling the bit that is concrete...?....

[Dave G]

I stuck the nomoreply over the concrete with the Ultra adhesive dave.

Now my entire kitchen floor is covered with the nomoreply.

Will do some pics.....just for you Dave lol

[Dave]

We love pics..........but as for the concrete meeting chipboard.....personally i would have put a movement joint there......


Can't wait for the pics......

[Dave G]

Whats a movement joint, how do you do one ?

[Dave G]

Dave pics are on (i think lol)

Hope I put the right ones on and not the ones of me and the wife on our hols



hehehe .'-)


an don't take the **** out of my tiling in the bathroom, the idiot who put the studding up when the house was built musta had his guide dog level it for him lol

[Dave]

Nice pics...can you turn them around the right way.....my neck hurts......

[Dave G]

nope lol

[Dave G]

So what do you think Dave?

[Dave]

Whats a movement joint, how do you do one ?

A movement joint is a stress-relieving profile/joint, compensating for the movement of tiles and/or the substrate. Without them the shear stress builds up between the tile and the screed, causing debonding, bulging and cracking.

Ideal for use between changing substrates...such as timber meeting concrete....you can use a pre-formed joint or just a cold joint( silicone)....

The timber will expand at a different rate to the concrete or there could be slight deflection at this point putting stress on the tiles.....

But if you have already installed the no-more ply then cross your fingers....

[Dave G]

Where the concrete met the chipboard I put some self adhesive scrim over the joint, then covered that with the ultra adhesive .

I also tried to get as much of the joint in the middle of the nomoreply board

Will it hold?

[Dave]

Pass!!!!....if the deflection in the chipboard was minimal then it might be......i just thought i would point this out , so that you know next time dave......
