So forget about cement boards and foam boards and just tile direct onto wood?

I would want it in writing signed in front of witnesses that Weber would cover cost of tiles, materials and labour for at least 5 years of tiles being down.

Cheap imported ply as the floor?
P5 Chipboard as the floor?
Hmmm.

but what room?

have you ever tried getting a builder to seal backs and sides before he fixes them ?

 

[Glynn]

The builders will not do much for a tiler, you should know that by now. You would have to take that control yourself, but the priming of the back and side of a ply-board was mainly when the boards were exposed to moisture going onto a groung floor jiosted floor where there was earth below it without a DPM. These floors are becoming less as most new builds are a solid screed and all housing must have a DPM installed.

I assume as tiling onto plywood has been vetoed since this video was shown it no longer applies.
Or is it just wall tiling on to prepared plywood substrate.
Either way I wouldn’t !

Which thickness ply do you use for testing. I have only ever seen SP101 in 6 and 9mm.

Best practice will always be Backer-board first. But the correct ply-board type can still be tiled. BS5385 changed last year. I ask why a substrate that the industry tiled to for twenty years that I know of and probably longer is now now longer suitable? What as changed in 6 months? In my role has technical support we go out to failure on ply-board but mostly they are of the incorrect type and not suitable for tiling from the start. The soft flooring industry use thousands of ply-board sheets every day and pour thousands of gallons of water based smoothing compounds over them and we get zero phone calls with debonding issues. Why can their industry be able to acheive this when the tiling industry acording to BS5385 need to be protected from this "not suitable" substrate. Nobody from BS contacted Tilemaster for our input has to whether Tilemasters adhesives are suitable and have been since Tilemaster developed them, and will continue to be suitable for fixing tiles to suitable ply-boards.

Tilemaster do all our lab testing on SP101 in 6 and 12mm.

 

[J Sid]

yes the BS has changed, why? That question is way above my pay grand.

the hard part from my, a lowly tiler, is getting the builder/chippy/home owner to use and prepare the wooden flooring in a manner so products such as yours can be used. Just will not happen, so much easier to overboard or recommend a flooring other then wood.

 

[Spare Tool]

Nice to see a manufacturer stand behind their products and actually give guarantees..

 

[Dumbo]

The reason it changed is very simple . Bal now do a wall board suitable for tiling .

 

[J Sid]

and how does an adhesive that can stick a tile to the correct wood flooring type handle the joints in said correct floor?

this is where most failures happen imho

I have to agree with you as I have also seen the failure at floor joint that has had hardie used on it .

 

[Glynn]

Exactly has it would on a backer boarded floor. First and formost the floor must be strong, no deflection and capable of supporting the tiling installation. BS 5385. The ply-board is only there to over lay an unsuitable substrate ie: chip-board, floorboards. If the main floor structure is not up to it yes the edges are where most failures occur. Is that the ply-board failing or the structure of the floor not being suitable in the first place.

 

[Waluigi]

This is the reason I do my own prep work.
I just wouldn’t consider doing the job if I didn’t.

 

[Glynn]

"Best Practice is" Trust no one to tell you "its good to go mate"

 

[Flintstone]

My thoughts on plywood is that it's probably the worst overlay surface you can tile onto and the sooner it's deemed unacceptable the better. Yes there are as Glynn says a couple of types of ply that are ok, but we all know that the important part of the spec of the ply wood gets lost in translation or disregarded and people end up buying builders yard 9mm ply. As for this Webber adhesive, well simply why would you risk it ?

 

[Waluigi]

SP101 isn’t easy to get either. In a 20 mile radius to me there are only two companies that sell it. Both only stock 6 and 9mm variants. Ideal for LVT
