You tank over the washers.

Screw wise, you have a 600mm Board with two fixing points at either end of the 600mm with no adhesive behind the board. Not very secure IMHO, especially with 6mm board.

Maybe it’s just me. I don’t do many overboarding jobs. I think the last time I did a wall I used HB, 6mm. Glued and screwed.

Copied from another thread about Jackoboard

JACKOBOARD® Plano construction boards can be fixed to timber or metal stud frames using JACKOBOARD® 36mm diameter galvanised steel washers and appropriate screws. If the frame centres are 600mm apart then boards of at least 20mm thick should be used. Fastening points must be arranged as per figure 3 or 4. If the frames are at 300mm centres then 10 or 12,5mm thick boards can be used. Fastening points must be arranged as per figure 5 or 6.

As the boards are over plasterboard in this case I don’t know if the same recommendations apply

Do you tend to rip out plasterboard and replace with hb etc

What was the studwork spacing?

I think the recommended spacing is 300mm for 12mm boards of this type.

Could be wrong though.

Was 400mm centres between studs

How big are tiles? Weight etc

What was the background surface?
You mentioned bonding in a previous thread was this over skimmed?

where the boards join, you can get away with a fixing staggering both boards.

The issue you have if you don’t glue the boards is that any inperfections in the wall, dips or bows, aren’t accommodated and you essentially could have a piece of 6mm board floating. More screws are essential, to pull the board tight to the wall if nothing else.

Is it a mixed wall substrate room? Skimmed bonding ? Plasterboard on studs?

 

[Waluigi]

Taping the joints helps to an extent, as the XPS wasn’t stuck, I would’ve used reinforcing tape and tile adhesive skimmed over.

The shower area are 1200x600 porcelain at 17kg each, the rest are 150x400 not sure in their weight.

Only one wall was mixed: one side was bonded over block, so drilled, plugged and screwed the backer boards over the bonding using 4” screws to get 3” of the screw into the block, the rest was plasterboard stud walls with a skim, so screwed the boards to the studs

Looking at the second picture it looks more like the door lining rather than the frame, you better check that so you don't end up miles out!

One wall was bonded to bring it square, which was on a block wall, so screwed the boards to the block with 4” screws

Starting to feel slightly stressed out & worried now .. so basically you don’t think the boards will be adequate to hold the tiles?

Only you can judge the adequacy of the prep!
