Tanking-Desirable rather than essential?

[A1P]

Hi All,I am a plumber / tiler and I get mainly bathrooms to do.I am more comfortable with the plumbing than the tiling.I am trying to widen my knowledge via the forum.Many of my customers are at the 'budget' end of the market so it is mainly ceramic tiles on a wide variety of walls and floors.As with plumbing none of the tiling is ever straightforward!!I get a lot of attempts to lower my quotes and most customers are a bit cost obsessed.Tanking seems hard to sell to them.How much,do I need it etc?I know there are thousands of bathrooms pre-tanking still going strong after 10+ years.Some were even PVA'd.Dont start that again!!! I saw a post that said Aquapanel was guaranteed by manufacturer and did not need priming.Another post by Wet Decs saying that painted tanking wasnt guaranteed unless it matched exactly the depth required.Impossible for tiler to measure so possible get out.Primed plaster boards have also been passed as suitable.Many posts favour membranes.I just want to do a good job so would welcome your opinions.I gather the issue is that no grouts are waterproof as claimed-just water resistant.Rob

Thats right about most of the grouts, I too have trouble convincing people tanking is the way to go.
I like the membranes, kerdi/dura which is like wall paper but have used a few others.
I even had to make good to someones neighbours house where the shower had leaked thru the parting wall.

iv'e got a shower in my en-suite that used to break down say every 5 years and i'd re do it ,then finaly about 2 year ago still before tanking had taken off i epoxy grouted it and so far no prob's

Same as my shower, plasterboard behind and epoxy grout used good as gold

If you juggle the cost of the tanking membrane with the excess on a houshold insurance and the inconvenience of renewing ceilings then most householders will go for it and view it as a wise option I think.

obviosly i know both wet and membrain systems that we are all adopting now, funny enough i'v been using both systems for years in the plastering ind ( damp proofing ) so i have no probs with the systems, just the ripp off prices of the materials really that you have to justify to your customers

Gooner59 (username ) COYG's have my first wet rooms to do soon but its in a ground floor - concrete floors and solid walls,I'll be sticking mosaic tiles in the shower area - should I tank it? and what with ?

 

[wetdec]

No need, you will need a membrane on the floor if its a new screed to avoid possible tile damage.

If its a new install take a look at the Tilux board

You can fill any areas by making it thicker and use scrim tape for support and in the the corners
