Homebase plywood recommendation

[afright]

I have just finished a bathroom,walls and floor using 600 x 300 porcelain which the customer bought from Homebase.The customer laid the plywood floor ,when I told him that the ply was not suitable he said that,s what Homebase recommend on reading the packing it states that flooring should be plywood to the thickness of 9mm.The customer would not remove the ply so I laid Ditra over the top,is Homebase right in recommending this thickness ? I for one always go for a thickness of a least 15mm and then still try to use Ditra,just would like other tilers opinion on this.

 

[peteablard]

15mm is bs minimum. Personally I still prefer to over board with hardi too

 

[Perry]

Homebase wouldn't have a clue the costumer should of asked the brick wall it may have more idea

 

[afright]

It was a case of he did not want to pay for over boarding so he settled for Ditra,Homebase did state to use their adhesive(which I did not I used mapei) it will be interesting to see what that state,s on their bags about prep.

homebase can reccomend what they like i suppose albeit the advice is wrong,you know what its like trying to change some peoples minds once they have it in there head they are correct

It's crazy that customers always want to listen to B&Q, Homebase numpties, but not the tiler they bring in!!!

I really don't want to sound as though I am trying to put people down but I am a 49 year old tiler with 31 years experience in the trade, I have never used hardie, always used 12mm ply, never weighed a box of tiles, to my knowledge never had a wall collapse due to the weight and never used ditra. If the correct adhesive is used there will be no problem. I still dont get why people replace plasterboard with aqua panel because its waterproof? The grout and adhesive are waterproof so the substrate should not have to be. As I said I am not here to put people down but adding these costs to a job would result in not getting a lot of work, cheers although I know I am in for a bit of stick

They are water resistant, not waterproof......

It's this lack of knowledge on new product that make it difficult for me to win jobs. I tank all wet areas, Silicon expansion gaps. Use uncoupling membranes on ufh or with stone. But because I try to do the best possible job I lose out because someone will say it doesn't need doing so can do it cheaper. Shouldn't we all be trying to improve the trade and do the best possible job?

Well I am 59 and have been tiling for 42 years and to be honest I to just kept to my old ways but did have a few problems over the years where tiles had cracked due to movement, so any new methods to better your work is much welcomed .

so what products would you use if you were constructing a wet room , surly not plaster board?

 

[bugs183]

You've been very lucky then Ian.
No one here will tell you what you should be using, but the trade has moved on massively over the years and the old methods simply aren't applicable to many situations that arise.
I've been tiling over 20 years, and you have to keep up with what's being developed.

 

[Perry]

i dont think we ever get to old to learn things have changed a little since we started doing 6x8 s 30 years ago changing faster day by day

 

[afright]

The whole tiling format is changing when I started it was mainly Johnson vein tiles on walls and quarry,s on the floor now tiles getting bigger and heavier and that's why you have to learn new techniques.
