Pocster Posted August 19, 2020 Author Share Posted August 19, 2020 25 minutes ago, Onoff said: The (blue) tanking needs to be continuous. I think the theory is that you should also use the tanking tape at any change in materials say where mrpb meets the concrete floor etc. Guess you primed like mine before applying the tanking liquid? You then prime again with tile primer (over the blue) before applying the tile adhesive. Wotsit to a blanket! Sorry re read your post . Tape is used at all joints ; like wall to floor transition. Board to board . Over every fixing within the shower ‘wet’ zone Link to comment Share on other sites More sharing options...
Pocster Posted August 19, 2020 Author Share Posted August 19, 2020 Actually have 2 waterproof kits ; 1 for ensuite other for bathroom . Used 1.5 kits just on ensuite . Link to comment Share on other sites More sharing options...
Pocster Posted August 19, 2020 Author Share Posted August 19, 2020 Come on @Onoff explain the point of this tanking in this ( or any scenario ) If water gets past grout / Mastik you have a leak but you might not know it yet . The tanking would just delay the inevitable, yes ? . So what’s it really for ? . Once the water has got to this tanking layer it will eventually appear on the ceiling below .

Pocster Posted August 19, 2020 Author Share Posted August 19, 2020 A random website ... ” When to recommend tanking Stocking tanking kits alongside adhesives specific to bathrooms, wet rooms and kitchens provides an excellent opportunity to recommend an additional product to your customer and make an extra sale” its just a bloody up sell !!

Pocster Posted August 19, 2020 Author Share Posted August 19, 2020 I guess the only real advantage I can see is if as traditionally you plasterboarded the shower walls then tiled . If a leak occurred the plaster board would soak that up and eventually the entire wall would become dubious . With these water resistant boards that’s less likely to happen i.e integrity of wall compromised . I *suppose* tanking protects the wall more . All sounds a bit snake oil to me ...

bassanclan Posted August 19, 2020 Share Posted August 19, 2020 If water gets past the grout/tiles, it runs down the tanking membrane and onto the tanking tape which is lapped onto the bath/shower tray, thus directing the water back into the tray rather than the board behind getting wetter and wetter until it eventually shows on your celing below 1 1 Link to comment Share on other sites More sharing options...

Have I done mine wrong then ? . I’ve done my tanking at the base and the tray would sit ontop that . Surely I don’t tank after the tray is in ??????? ?????

Pocster Posted August 19, 2020 Author Share Posted August 19, 2020 (edited) Aaarrrgghhh its all wrong ! The tanking kit is for the suppliers wet room flush tray ( which I don’t have ) . So tanking is pointless in my case ??? . Surely I don’t fit a ceramic tray and overlap / tank the strips over that ??

Pocster Posted August 19, 2020 Author Share Posted August 19, 2020 Ok ! After numerous phone calls to tanking company and seller ... I assume my tanking has ‘lesser’ benefit in this situation and it really is all down to the silicone around the edges ..... What’s the worse that can happen ? It leaks - I’m use to that ! ????

OK, son has been 'mowed' and we can see his ears are actually there still, even though he seems to not respond to commands such as "clean your room"....... Tank the walls about 300mm from the UNDERSIDE of the tray upwards and leave to dry. It dries quick as a flash, and you should be able to second coat it in an hour or so. Don't put it on like double cream, just a decent couple of layers and happy days. Then fit the tray as per previous ramblings, shifty from side to side / front to back / CT1 squirted in etc and leave to go off. Wipe any excess CT1 off the tray with baby wipes and walk away for a beer ( or Mad Dog 20/20 which is probably more you ). Mask the tray 5mm in all round, and then go for second session with the CT1, where you fill the voids around the tray and 'tool' the excess up the walls a little to form a one-piece up-stand out of CT1 which carries on up the walls about 30mm or so.Use a bit of stiff cardboard ( nothing plastic or it'll damage the tanking ) to form a nice 90 degree internal angle in the wet CT1 and relax knowing that bar steward will be dry as Bin Laden's flip flop for many years to come.
