BAL Bal GT1 Admixture.......... - TilersForums.com

Has anyone ever used this in other grouts besides bal to make them more flexible ...
I know you shouldn't do it, and bal would never recommend it........ But in the real world do you think it would have disastrous consequences if used in grout 3000....?

Andy why have you a problem that you need a more flexible grout?

Got a rush job in tomorrow, and maybe using tilemaster Grout 3000, it's a timber substrate and I prefer to use the tilemaster additive to make it more flexible....... Only trouble is I can't get hold of any till the end of the week but got loads of GT1 on the van...

I used to use Bal and Ardex and Feb Pci grout admixes with all sorts of grouts. Even had to mix grouts together in the old days as none of them used to do the grouts they do nowadays. A lot of the admixes are supplied by the same manufacturers.

Grout 3000 is flexible anyway without adding anything to it. Adding flexmaster additive makes it terrible to use, sticks to the face of tiles like glue

I believe gt1 is pva, albeit a very good, possibly modified pva.
I doubt adding it will do any harm, other than invalidating any warranty.

It's recommended to add it to the grout on a timber substrate to increase the flexibility...

Not sure it’s needed unless it’s a ‘problematic floor’. I stand to be corrected tho.
When i first started using grout 3000 a few years ago I’m sure they said you need it with polished porcelain/rectified to help it stick to the edge.

T&G floor boards and floating floors.
Not saying I would ever tile on any of these substrates...... But there timber floors and although I always overboard them with hardie or insulation boards I prefer the belt and braces approach...
