Tiling onto Hardi Backer board

[tileman]

Hi, I have a bathroom to tile with ceramic tiles, one wall is lined with Hardi Backer Board, the builder has supplied Granfix Supa Grip, I told him I thought the Adhesive should be a bagged cement based, I checked with local tile shop they say cement based.
The builder says he has checked and the Supa Grip is OK.
Which is the correct adhesive and why.

:helpsmilie:

Cement based for me, especially as its in a wet area. Tubbed adhesives are, a)Likely to fail if they are exposed to water for even short periods of time, cement based won't, b) Wont support a tile any bigger than 300x300mm and c) Can't be put on any thicker than 6mm ( this does vary from each manufacturer), so if there are places that need building out (dips in the walls etc) then it can't be done.

The tiles are 8mm x 350 x 250

Who is the tiler here..?

Tell the builder to stop being a tight *** and get you want you want to use,after all you are the tiler and you are offering the guarantee... not some cheap scate builder..🙂

I agree with the guys above. Tubbed adhesive is suitable BUT powder adhesive is far better in just about every way.

Give the builder a slap and get him to get you some powder and do the job the right way

My favourite is when a builder gets the exact amount of tiles for the job..and by exact i mean exact!!!
