Adhesive/Grout etc to buy tomorrow....

[kevg]

Could one or two kind people do a little sanity check for me and just make sure I have not missed anything out ? I'm buying everything I need to do my rooms tomorrow.

Kitchen (concrete)

Floor - Concrete
Tiles - Porcelain
Membrane - Dural Ci or Shluter Ditra
Adhesive - Keraflex Maxi
Grout - Mapei Jasmine

Toilet - (concrete)

Floor - Concrete
Tiles - Porcelain
Membrane - Dural Ci or Shluter Ditra
Adhesive - Keraflex Maxi
Grout - Mapei Jasmine

With both of these floors being concrete, would I need a primer ?

Bathroom - (Woodchip)

Floor - Woodchip
Tiles - Marble
Membrane - Hardiebacker 6mm or something like Marmox
Adhesive - Keraflex Maxi
Grout - Mapei Jasmine

En-suite 1 - (Woodchip)

Floor - Woodchip
Tiles - Marble
Membrane - Hardiebacker 6mm or something like Marmox
Adhesive - Keraflex Maxi
Grout - Mapei Jasmine

Ensuite 2 - (Woodchip)

Floor - Woodchip
Tiles - Marble
Membrane - Hardiebacker 6mm or something like Marmox
Adhesive - Keraflex Maxi
Grout - Mapei Jasmine

With the upstairs rooms all having a cement based backer, I assume no primer needed for this ?

I'll also get some joint tape, screws etc that I'll need, but have I missed anything important out ?

Use primer on the concrete, you should also consider some tools!!!!!

Thanks Brian

Yeah never mentioned that as I have a wet machine with diamond blades etc, knee pads, sponges, trowels etc already.

Anything glaringly obvious I've missed ? My choices ok ?

 

[kevg]

Grout sealant, tile sealant. Forgot about those.

 

[Ian]

I would also consider a de-coupler membrane for the ensuites and bathroom especially as you are using stone.

Should I use my choices for the concrete ? i.e. Some of the Dural or the Shluter ? And would that mean instead of the Hardiebacker ?

 

[Ian]

Fit it over the hardi, if the floors are small, say 3/4m2, it may not be necessary, just a little bit of extra security.

 

[kevg]

Will do, thanks Brian. This is going to cost me a pretty penny.

 

[Ian]

Not as much as if you have to do it twice!!!! Good luck mate, look forward to the photos.

 

[kevg]

Just seen Keraflex Maxi S1, should I get this rather than the standard Maxi ?

Your not wrong there. I appreciate tha Brian thanks. Yep, I'm a photoholic so will have lots for you lads to giggle at lol.

 

[sblunde]

Keraflex Maxi is S1 anyway?

Not sure myself, I just see one branded with S1 and one thats not.

Got the stuff I needed today. Will pick everything up when I move house very soon.

Was told I dont need any de-coupler for the concrete or chipboard. I got Latex Plus instead which according to Mapei, the Latex Plus with Keraquick is fine for tiling right on to Chipboard. And for concrete only Pro Flex is needed.

I assume this is ok ? Almost £1500 worth today, felt like I never bought much lol.

Sorry but tiling direct to chipboard is not right.. no matter what the tile shop told you.. the tile adhesive might well stick to it but the chipboard will not hold the tiles..

Oh no. What do I do Dave ?

 

[kilty55]

you dont need the mats for the concrete floors imo

as above as well dont tile direct to chipboard kev,go with the cement boards as planned

 

[kevg]

ok, so the concrete floor is fine..

If I lay something like no more ply on top of the chipboard, would that be ok then ? So my layers would be..

Chipboard
No more ply (screwed)
Adhesive
Tile

I wouldnt have to put an adhesive layer between the chipboard and the no more ply ?

 

[Mike]

if the chipboard is solid i would overboard with cement boards (hardi or similar) lay them with the adhesive and screwed 200mm centres. the jasmine grout dirties easy so if you're adamant on using it make sure you seal it. i've recently done a full bathroom in marble grouted with limestone and looked awesome. good luck

 

[kevg]

What I find is there is not a correct way that everyone adhere's to. Tile Giant tells me its fine to tile directly to the chipboard, Mapei says its fine to tile directly to chipboard as long as Latex Plus is used. Various people use backerboard then tile and others use backerboard and a membrane then tile.

I'm finding it increasingly difficult to find a method that will work for me and one that doesnt involve multiple layers upon layers of adhesive, backerboard and tile that will have my transition from one room to the other the size of a pavement step.

 

[kilty55]

hiya kev i understand your getting frustrated

please do not tile to the chipboard just remove the thought right out your mind as imo it will end in tears
you dont need a membrane for your concrete floors, and i would just use a backerboard on the chipboard floors as long as they are solid

i use these methods in most installations you have described and never had an issue i hope this helps

Mapei say the adhesive can be used on chipboard.. i do not dispute that.. what i am saying is that the chipboard isn't a suitable substrate to tile directly too ..

It is time retailers and adhesive comps recognise this as well.. after all bs5385 does..??

Thanks Dave, I completely agree.

Would I get away with laying 6mm no more ply glued down to the chipboard and screwed ? Then tile directly onto that ?

As long as it is deflection free then yep.. no probs..

Done ! Will order that up tomorrow.

Thanks again. Don't know what I would do without this forum.
