been reading nearly all the posts on here and everyone is telling me to buy Mapei because its cheaper and as good as bal. there are that many different types and i am confused. floor is ply on floorboards fitting underfloor heating 24sqm 600x600 polished porcelain tiles please help thanks dan

KeraFlex, KeraFlex Maxi or Keraquick with Latex Plus

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...

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.

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)
