Should Hardiebacker boards be used or not?

[charlie1]

HardieBacker is fastened to the subfloor with nails or screws, not exactly with the adhesive. The intent of the cement based adhesive is not to make the board stick to the subfloor, but rather to be used as merely a gap filler to minimize the imperfections of the floor. The installation system has been rigously tested and HardieBacker performs best when all of the steps in the installation guide are followed.

i can see why it would perform better using non flexible adhesive, the combination of the hardie and the adhesive becomes one solid slab rather than hardie with a flexible bed which could theoretically have slight movement.

I will definitely be using Hardibacker boards

Picking up on what Rookery said; as Hardibacker recommend laying the boards on non flexible adhesive for GAP FILLING purposes only, and seeing as my chipboard flooring is dead flat, then should my boards just be screwed down without using adhesive?

You can only go with what the manufacturer states, if you dont then you are on your own should anything happen.

I'd still stick them, it's good practice IMO

I don't believe the guy has been tiling long if he says he can tile onto chipboard.

@Whitebeam While it is most common for people to use screws, nails are also warranted. A 25mm-30mm galvanized roofing nail is just fine. At the end of the day it's a matter of preference.

@Jason If you search around on some of the chipboard manufactures websites, you'll see many of them state that tiles should not be applied directly to the board.

An example would be Steico UK, they directly state "Please note the fixing of ceramic tiles directly to the board should be avoided and an inert barrier should be placed between board and tiles."

If you ask your tiler to follow all of the installation steps provided in the HardieBacker Installation Guide, you can be confident that you will have a floor that will last.

according to james Hardie a 6mm panel should be used on a masonry wall.Has anyone done this as I thought you should use 12mm

Use a backer board defo chip board will break after a while

I didn’t want to completely dismiss my original tiler, even though his idea was to tile directly to onto my P5 chipboard, as he had previously tiled for me and friends in the past with excellent results, so I did one last bit of research and discovered Norcros Direct to Wood:

This is the product my original tiler wants to use.

I contacted Norcros Adhesives, and asked them to confirm, “Can I tile directly onto P5 chipboard flooring with Norcros Direct to Wood”?

This was their reply:

Good Morning Jason

I can confirm that Norcros Tile Direct to Wood is suitable for tiling directly onto P5 flooring grade chipboard subject to the board being securely fixed and deflection-free.

Please find attached a copy of our ‘How to’ and product data sheets for this product.

I trust this is satisfactory.

Any thoughts on this product?

Overboard with Hardie imo, the key word in Norcross or any other rubber crumb adhesive is deflection free. I would never tile directly to any type of chipboard, just not a good substrate.

Hey, you can also go to B&Q and buy a tub of Unibond 'Tile on Wooden Floors', its adhesive and grout all in one and eliminates the need to overboard... or take the advice thats been given by nearly 100% of the replies?
