KeraFlex, KeraFlex Maxi or Keraquick with Latex Plus

you have a few options really....


1. overboard with hardi or eqiv.
2. lay heatmat...use slc or adhesive to cover wire.
3. tile away

--------

1.lay heatmat
2. Fibreplan heatmat.
3. tile away


in either case i would use keraquick, but you can use keraflex maxi...

more info on your skill would help!

You want the flexible stuff suitable for porcelain. Though I'll let the lads name the brand/make as I don't tile anymore.

For the record, Mapei is the largest manufacturer of building materials in the world. BAL has a chunk of the UK market share. That's why the price is better for better gear if you go with Mapei. Checkout their grout-ranges too, loads of colour choices, and they match their silicones. No other manufacturer does that, and I'd got for mapei for that reason alone personally.

Ahhhh - you two beat me to it.

You'll want flexi adhesive,you can use keraflex or P9.Make sure the floorboards are secure and the play is screwed every 250mm and prime the top and sides of the ply.

keraquick is s1 without latex plus, its S2 with latex plus...and then you can stick to metal........

my skills are minimum.

am electrician by trade but done some wall tiling and done a pretty good job of it

also does the face of the ply need sealing if i use mapei

eco prim t.......i belieive!

s1 is fine for ceramic and stone and porcelain and ply,
S2 is even more flexi........not needed in common installs!

that said 18mm ply over floor boards or S2!!!!! for me!!!!....and never less than 12mm ply.......ever!

so is keraflex maxi a (s2) ?? and is it single part or does it need to be mixed with something??

maxi is S1 and single part.....and fine for you, if 18mm ply!
keraquick is S1 and single part.....and fine for you, if 18mm ply!

keraquck and latex plus = S2......two part!

if it was me....

12mm or 18mm ply.....no deflection,
i would, lay the heat mat on the ply.
SLC the ply and heatmat with FIBREPLAN.
once flat....even if it means FIBREPLAN AGAIN,
i would use Keraquick (coz im fast) or Keraflex/maxi (coz im slow),
and grout with ultracolor plus.....thats it!

IMO.

Kindest Regards

Dagger!

the underside and edges need sealing with primer too, if you're using mapei adhesive "primer g" is the stuff to use

If you go down the Keraflex route, make sure its Keraflex Maxi and not the ordinary Keraflex, as the normal stuff can only be used on tiles up to 300 x 300 for UFH installs (according to the tech sheets)

i spoke to mapei recently,
and they no longer reccommend primer g for wood....
Primer g should only be used for plaster, and SLC.......

anything else needs to be primed with "eco prim t"....i know, i know... but primer g has almost become redundant!!

the rules are changed again........dont shoot the messenger!
