Moisture resistant MDF

[lockett]

Hello

I'm putting in a new bathroom. After removing the plastic cladding, in some areas the plaster board has disinterested so needs patching. Also I have an area of floor where the bath was, that needs levelling up to match the plywood that has been laid for ceramic tiles. Both these area's at quite small so a full sheet (I have tried half sheets but can't find anyone who supplied them) of plaster board and marine plywood would be an over kill and would mean me scraping a lot of the boards. Could I use Moisture resistant MDF for both wall and floor, areas?
Thank you

It's not actually moisture proof, just resistant. It won't last in that environment.

Knauf Aquapanel/Hardie or similar? or Wedi/Jacko board?

Thank you for your response, not wishing to dismiss your opinion, the speciation for moisture resistant MDF states
"MDF is also used for panelling and cladding purposes within a building, due to the ease with which it can be carved into different shapes and decorated. Things like architectural mouldings, window sills, and skirting boards can all be made with moisture-resistant MDF and used within a bathroom or kitchen environment"
Has anyone had experience of this material failing in a bathroom environment.

Yes, I see it weekly on new builds and refurbs done a few months previously.

I would like to thank everyone for their advice, I won't be using the moisture resistant MDF.
Since the plaster board and plywood boards are the same thickness 9mm, I can easily get 9mm external plywood class 3, I will use this to make up the floor and repair the plaster board wall. I would have went for the moisture resistant plaster board but do not have the means to transport it in the sizes available and the delivery charges are more than the price of the product.

Thanks once again for all your help

The shops that sell it normally also sell the necessary tool to resize it, if you don't already have one to bring along
