Applying tiles onto either hardboard or plastered plasterboard

Possom

I'm to have new plasterboard installed in my bathroom, and then tiled.

I had just assumed that the plasterboard would have to be plastered over before the tiles were applied, but I've heard that it's possible to instead apply hardboard over the plasterboard instead and then tile over this. The tiles are to run the full height of the wall.

This means the tiles can be successfully removed at a later date without destroying the plasterboard which would happen during removal if they had been applied directly onto bare plasterboard.

If applying the tiles onto hardboard-covered plasterboard, is this cheaper and/or quicker than applying tiles onto plastered plasterboard? That is, including the time of plastering and waiting to dry.

I'd be getting someone in to do the work.

Thanks!

You can't tile on hard board it's called hardiboard which is a waterproof cement board, you should use that in the shower areas, you don't need to plasterboard first just fix this to the stud work

I'd say its probably as easy to fit new plasterboard (if) and when you re-tile as it is to plaster the existing stuff. I'd tile over the plasterboard and worry about any damage when removing them many years into the future. I can't say I've ever tiled with the intention of removing them in the near future, it's a pretty long term project.

this person above talks sense . good luck getting them off without damage though . I would make sure tiles in bathrooms are as stuck and sealed as possible

But plasterboard isn't waterproof as anyone that has had grout or sealant fail will tell you because it goes mouldy & falls to pieces which leads to more leaks & loose tiles, which is why in shower areas you should either use something like hardiboard or similar or if you use plasterboard it needs tanking before its tiled

General purpose plasterboard isn't waterproof but there are products on the market that are.
As the OP is getting the plasterboard in the bathroom replaced, it would make sense to make sure that one of these products is used.

Thanks for this. So are the tiles then placed directly onto this hardiboard, it doesn't have to be sealed in any way first by, for example, plastering?

Just to clarify, I had been thinking about damage to the plasterboard in the future if removing the tiles, and not damage to the tiles. That was because damage to the plasterboard would require having to also change the plasterboard and not just the tiles.

No.

But maybe you weren't thinking about the huge weight of the tiles!

Don't waste time and money with hardibacker

Standard plasterboard with either a roll of Homelux water proof matting or mapeigum with corner joint tape

Homelux is the superior option , we have well over 100 wetrooms with this system , many 4 flights up and not a failure yet

Hardi has silica in it , you'd need good masks to ensure the risk is low . You then have to bond it to the wall or screw with there washers . It's time consuming and expensive and those that think this is the superior option need to give there head a shake ! You still need to seal the board edges to ensure its 100% watertight

I just had a look at that product online.

How is it secured to the plasterboard wall? Is a particular type of adhesive used, or does it possibly have a self-adhesive back?

So once the water proof matting has been fixed up on the wall, are the tiles then simply applied directly onto the matting?

Homelux or similar is fixed using tile adhesive, you then tile over the matting.

Your layers are adhesive, matting, adhesive, tiles.
