tiling on plywood

[The D]

It dose not say you can not tile on to ply it just says it should be avoided were ever possible.
If it is unavoidable there are procedures to follow to minimise the risk of a failure.
Was the back and the edges of the ply sealed before it was installed ??
Do the joints of the ply coincide with the tile joints ??
If the above has not been done and your client still insists they do not want the ply removed you could suggest they take the precaution of over boarding this can be done with 6mm Hardie backer or even 4mm Wedi

Thanks Deano, nothing has been done and I didn't check the joints. It could be nice good job forexample she goes for Silestone shower trays 1600x900. Silestone Top above bath and units. Each shower area has niche boxes 600x400x100 with spot lights from Mosaic and about these areas I am worried most. There'll be water standing all the time,becouse they will be half meter from shower heads. Wall hanging units for basins in each bath. I don't want to lose this job. If say something to the designer, he will ask me simple ques. Do you want to do it, or not? Believe me he will find somebody to stick the tiles on silicon. I would have to change costumer's mind, but If I do it, then it will be my last job for this Design Studio, becouse He will look a like someone Who doesn't understand it.

Firstly it's ply and not play:lol:

secondly I know where your coming from,the amount off plumbers,joiners,builders and even bathroom companies I do work for just laugh when I tell them the substrate isn't ideal for tiling,there attitude is...."iv been doing it like this for 20 years,if you don't want he Job ill get someone else"
I always say well if they come off or grout starts cracking,ill not be back fixing it for free.

there have been times when I point blank refuse, but when there's bills to be payed it makes it hard.

Just returned home after trying to start a shower 40miles from where i live.
Previous tiler tiled straight onto particle board, funnily enough it had leaked, so the wood is shot. New plumber has removed tiles, left adhesive all over it and it flaps about.
Large format 400x250 tiles so this has to be right.
So tomorrow i have to tell him the boards are unusable, so that makes me the bad guy. It could be screwed, tanked with Mapelasic Defense (which i always use) and roll acrylic rendering mesh into this. It would be would, but it's not the point, it's still me having to do make do some elses job again.

Firstly it's of, not off.. :lol:


Sorry, couldn't resist that lol!



Secondly, you're bang on the money. I have the same understanding with any builder i work for.. We either do it my way, or it gets repaired at their expense.

Firstly, it's "I've" not iv! :smilewinkgrin:

Sorry, couldn't resist lol.......

It can be very very hard to do the right thing, especially when you are working for someone else and even more so when you need the work, things aren't easy out there and the last thing you want to do is upset people that can be good sources of work, but having said that when it goes wrong it will come back to YOU, the Tiler and not the other guy, and then it will be YOUR reputation as a Tradesman that gets damaged, and that won't help you build your business, so think very carefully about what you do, good luck!

I spoke with Mapei technical advisor today and was assured that ''Ply is ok for walls''. He told me to use Mapegum WPS for tanking, Keraflex Maxi S1 or Keraquick S1 adhesive and colour plus grouts.
I am the bad guy already. Customer called designer about my advice and He called me questioning '' Why did I tell her that''.

 

[beanz]

You told her that because IF it fails, it's going to cost you money!!

Who's paying you, the designer, or the customer? If it's the designer, you should've had the conversation with him. If it's the customer, then it's between you and her..

 

[The D]

I better call the British Standards Institute and let them know that your clients designer is not happy with there guidelines :lol:
