grouting early

[boldydave]

just another question for you all.i`m using keraflex maxi on 45 by 31cm ceramic tiles onto plasterboard.grout is ultracolour plus white.it would make my life a lot easier tomorrow if i could fix 2 tiles to finish a wall and then grout the whole wall 2 hours later.i know, i know, the adhesive should be left much longer but as it`s just 2 tiles(the cuts to the floor in a corner)what am i risking? the tile not adhering?the grout discolouring? i`ll get a bag of fast setting addy if i need to but wanted to know what you all thought. thanks dave.

if you use rapid set (bagged of course) it should be fine. it's not a dispersion adhesive so you're not trapping the moisture in there. you could leave that area till last just to make sure.

thanks mike.i`ve got keraflex which is a slow setting addy.just wanted to know if i realy need to get some fastset just for 2 tiles.

 

[Mike]

even that should go off in an hour on plasterboard

mix it with hot water ....that will make it go off quicker

 

[boldydave]

thanks very much.it saves me time and a trip to the merchants.

Cement based addy will still dry even after it's grouted. for two tiles it will be fine

i'm sure for just 2 tiles there would be no problem

No problems with that, leave spacers in at bottom(cuts of spacer hid) just to prop up nicely and grout over.
Just added protection.

The stated time is 16 hrs.. if you want to grout early then use an appropriate rapid set.. can't believe trusted advisor's and established tilers saying this in an open forum..???
