Screws For Tile Hardie Backerboard

[DazJWood]

I know Hardie do their own screws for their backerboard but to cut down on cost what sort of screws could I use as an equivalent.

I will be putting the 6mm backerboard down on the floor over 18mm WBP ply and I'll be putting 12.5mm backerboard up for the stud partition wall for my shower cubicle.

The reason I ask is that I will be putting marble floor tiles down and am thinking about travertine for the walls. As these are both natural products and have porous surfaces I want to eliminate any screws rusting through into the back of the tiles once they are fixed.

Can anyone recommend some 'rust proof' screws ideal for the purpose?
(or is my question a stupid one and the majority of screws available would suit?!)


Thanks,

Daz

Stick with Hardibacker screws and absorb the cost as you dont want any rusting ruining your tiles as you suggest.
Or use a stainless steel screw but still very expensive.

might be worth a thought if you waterproof that will eliminate the rust issue and give you peace of mind to :8:

Thanks for the replies!

I was actually going to put up homelux over the hardiebacker board for the walls so I guess the type of screw for the wall is not going to matter that much.

Although the floor I am not intending on waterproofing so I may buy some Hardie screws for that purpose.

Thanks!

hi dazjwood

the screws definately need to be corrison resistant mate. moisture does get to them even from the inside from hot/cold spots so its important to get the correct screws even if it is a little bit more expensive. they are the anchors to your substrate and if they corrode over time it would be a shame due to such a simple measure.

all the best mate
