For the second time in the last couple of months, ive had problems where the BAL tubbed addy i was using hasnt gone off (1st time with Green star, 2nd with Grip). Has anybody else had this problem? The only thing i can think might have caused it may have been because the tub could have been open several hours before it was applied (ie at the end of the day)

Thanks all..

what tiles were you fixing

What type of tile are you trying to fix with it? It's been years since I last used tubbed addy, as I always use powder.

In both cases, they were small metro style brick sized ceramics. I normally use powdered addy for anything over 300x300 but these were a fraction of these dimensions

what size was the trowel you used?

Also what did you tile onto?

6mm V notched trowel onto tanked plastered wall and WBP. In the case of the WBP, i went back today to replace some loose tiles and the addy was still pretty soft which was scary because i tiled it several weeks ago..

i have seen cheap tubbed gear bal green star in particular do this before when someone tiled a plywood wall with it the tiles fell off,i can only assume the moisture has been sucked right out the addy by the ply

I only use ready-mix addy on a kitchen wall and never on WBP.

I cant see how it would make a difference on the basis that the WBP area was primed and tanked. Interestingly though, ive been using ToppsTrade on exactly the same substrate and not had this problem so far..(fingers crossed)!

Better safe than sorry though.
Bal Tubs are good but for the time it takes to mix up a bag of powdered,even by hand,i think its worth it.
hope it works out for you

if you have gone to the trouble oftanking it why the hell of you using ready mixed addy ?

splashback in kitchens only me thinks

i dont think your meant to use tubbed on tanking anyway that may be the issue

if the moisture has no where to go it is like putting the lid back on the tub. cement based adhesive is required in these situations

Ah tanked, with dean on this then

you dont use tubbed stuff on tanking or waterproofing as dean mentioned

Thanks all for your thoughts. As im still in my first year, im still learning so this type of feedback in invaluable. Clearly, it appears to be related to having a tanked substrate not allowing the evaporation to escape so ill stick to powdered adhesive in future

Will you have problems with the remaining tiles

Thanks WB, i went back and fixed the loose tiles last night and the rest seem absolutely fine. The problem tiles in question were on a small box section but the rest (on plastered walls) seem fine and dandy..

I was going to post but kilty hit the nail on the head, dispersion wont go off over tanking

just realised that dean , john and jay have said the same

im with the four of you

And I'm with him ^^ but not any of the other three (no reason, it just seems a bit crowdy now).

Thanks for sharing this experience anyway mate!

These types of posts and responses are what helps other people learn

I just asked in my local well known tile suppliers about using tubbed adhesive over tanked areas, all the staff joined in the conversation all ''advised'' that there was no problem in using tubbed addy. I argued the point, so the manager got on the phone to the regional BAL rep........he agreed with them!

Thank god for this site, It really is a minefield out there when it comes to so called informed professionals

how can we trust any thing these people say i was told by BAL tec that they will guaranty fast flx on to chip board and on to floating floors.

CTD and Topps are selling tubs of green star for about £ at the minute.
