Hi guys, can anyone tell me the best way to get that green waxy stuff of chip board floors so I can bond it, it just clogs up my sander so I have been using a scraper

Overboard it in 6mm hardibacker :yes:

Yeah, overboard it... Isn't exactly ideal to tile (or pour slc, or much else either for that matter) directly onto chipboard.

The green stuff is wax which they add when they make the board.

If you ask the majority of adhesive co's they will mumble their way through which adhesive or product you can use on it but wont guaranteed satisfaction.


The reason : Because houses have central heating & hot pipes the temp of the board rises and the wax can soften and release adhesives etc.

I have tiled onto with 2 part flexi and it was fine, but like the lads say product companies wont recomend it.

Granfix say their Ultimateflex adhesive is good to use on this providing the board is keyed and primed first. Have used it alot and it sticks like s**t!

How would you be fixing the hardi?

Glue and screw

Glue and screw

What kind of glue?

And how many screws?

Never used it and only read the documentation thats says stick it with addy and a few screws, making it useless on this kind of waxed chipboard IMO.

Wouldnt like to stick then find it popping a couple of weeks later.
