Always use a good quality adhesive that you trust

sorry to here your predicament but i haven't used ply to tile ceramics on in 15 years. there is products out there much better suited than old ply to tile ceramics on.

 

[On one]

After waiting 7 days to even get anyone to look at this floor and then another 4 days I get this ridiculous email from Weber! I told them I'd used WBP hard wood ply which has Mahogany in it. They're telling me not to use ply with Mahogany in it! Now can anyone tell me of a hard wood WBP ply which doesn't have Mahogany in it??
My conclusion is if you ever have a problem with Weber then tough luck as they'll do nothing to help. AVOID THEIR PRODUCTS!!

Observations:
The tiles had been fixed to a high standard with a full bed of adhesive. The ply that had been used as a substrate was described to us as being a mahogany hard wood. The tile adhesive is our weberset rapid trade S1 product.

The Mahogany ply is also known as “luaun” and is not a suitable substrate for tiling. The veneered mahogany surface is glued to the board using water soluble glue which softens when exposed to moisture from the tile adhesive.

We understand that another manufacturer’s product was used to bond tiles to the ply and this worked with no failure.

Recommendations:
We would recommend that the ply is removed and an 18mm WBP ply used to replace it. WBP ply is water and boil proof and should be primed on the back and edges. The boards should be screw fixed to a joist or a noggin at 300mm centres. Tiles can then be re fixed with a solid bed method as used previously.

So I'm reading this as....
You've told Weber that you have used 18mm WBP plywood,
Weber have told you that your WBP plywood is glued together with water soluble glue.......so what the hell does W stand for in WBP?????
Then Weber tell you to use WBP plywood again?????
Stinks of someone that hasn't got a clue of what there talking about, and just opens their mouth and a load of ***** comes out

Isn't the W for weather not water?

Just googled thishttp://www.contractflooringjournal.co.uk/blog/plywood-there-is-no-such-thing-as-wbp
I actually thought the W meant waterproof
Never mind what it means. We now have better alternatives but, WBP plywood has been used for decades.......so does that mean that every job we have done in the past has ended up in the same predicament as this failure, I think not.

Really, who screws ply right through to the joists or noggins when over boarding ?

I do if I can. Putting a screw into old floor boards never gives a good fix. Always beeter to pick up the joist below if you can.

And a pipe or a wire 🙂

Exactly. I've used the same ply for years with no problems. The only thing I used for the first time was the Weber set S1 adhesive..never again.

You take a few up first to check for that.
