Another Question about hardiebacker

[willtile]

Never used before but got a job next week. Brand new house, bathroom floor. The floor currently has 22mm chipboard down, and removing it is not an option. It is inly a small area and is very very sold - no detectable bounce/deflection anywhere.

What would be the best option

1) 6 mm hardibacker board - if so, does it HAVE to be stuck down with adhesive as well as screws? Seems like overkill to me.

2) 12 mm ply. I've used ply many any times in the past, never any issues.

WHat would be best?

 

[diamondtiling]

Option 1, adhesive and screws.

 

[Max@ableskills]

Agree with diamond tiling use hardi, 15mm ply is british standard for fixing anyway

 

[kilty55]

why is a 6mm board screwd down onto a thin bed of adhesive overkill? its a better option than ply imo

 

[Ian]

6mm boards with adhesive and screws, make sure the addy is flexi! Its like tiling with big tiles and you wouldn't tile without any adhesive!

as above.

You can get specific glue for hardie, be careful you dont get it on your hands and lean on the floor....:yikes::yikes: it will take your skin off.

You don't mean no more ply

I glue and screw Hardie using Mapei Keraquick and latex plus. Just my way, but it seems to work.

 

[Thespanishtiler]

glue and screw with Benfer leaderflex, like you phil it works well for me.

never used a tube glue as i feel it wont fill the voids/create a laminate effect.

Thats exactly how aqua panel by Brittish Gypsum recommend fixing there backer board mate! (flexi adhesive) Nothing wrong with that whatsoever in my opinion.
