Hardiebacker instead of plasterboard????

[bluevin123]

Hi all,

Have got a 30m2 bathroom walls and floor to tile, anyway I
Started chipping away at the existing tiles, and pretty much took all the walls down as well just leaving the studwork.

The customer says he will put up plasterboard to which I agreed but after some serious thought I suggested he put up 12mm hardiebacker board up...They can take up to 45kg2m whereas plasterboard can only take 32kg2m.

The tiles are 600x300 copper honed slate tiles which are 12mm thick.
It works out about 30kgm2 in weight without adhesive and grout.

Do we just screw the hardie to the studwork every 12 inches and make sure it is stable or is there anything else we should consider doing?
Hope to get them up tomorrow with a view to starting next week.

Do you think this is the safest option?

Thanks.
Vinnie.

Hi Vinnie

I think you have to screw the hardibacker every 200mm on each support and then all the joints taped and jointed. stagger the joints if poss, and noggins behind all joints.
Hope this helps


p.s. there are dedicated hardibacker screws that you should use.(non corrosive)

well answered gazebo you can use stab (plasterboard adh for studs) to help :8:

Thanks Jay.
Can you clarify what you mean by using stab(plasterboard adhesive) for studs on a stud wall, or do you mean dot n dab with plasterboard adhesive then when dry screw fixings into dabs.

Cheers

Pink grip i feel would be the same type of product.

So are you saying pink grip should be put on the timber studs before you screw hardibacker to them.????

 

[Gazzer]

PINKGRIP DRY FIX is a revolutionary new type of fast curing, adhesive foam that has been specially developed for the rapid installation of Plasterboard, Insulation Boards and other sheet materials such as Roof Decking and Floorboards. PINKGRIP DRY FIX provides significant labour saving and convenience benefits when compared to traditional dry wall adhesives. It will bond to most common building substrates; can be applied horizontally or vertically to the board, wall or battens/beams. The foam expands very minimally on application but enough to fill any gaps on uneven surfaces.

PINKGRIP DRY FIX can only be applied using an Everbuild Dry Fix Applicator Gun.

Have you used this product on timber stud walls yet.?

Surely its just as easy to screw to timber studs.

I can see it might be usefull if you dont want to use the dot n dab technique for overboarding solid walls.

Anyone used this product.??

I have just watched the Everbuild pinkgrip dry fix video and yes you can stick plasterboard unto timber stud fixings without screwing..

Ready to plaster skim in 1 hour also. not sure if it would be any good for really uneven walls but might be worth a go 1 day.
