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

 

[Andy Allen]

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..???

How about using "dirty water" as in the water used to cleaned buckets, tool etc. In Plastering its used to make the plaster set faster. Not use if it would effect the addy structure, just a thought.

Why would you want to set the plaster to go off faster, you have no control on the setting action of it.

my mate does it sometimes, on a cold damp day when it takes hours going off. it just means it's not so long between floats.

Here`s what not to do...... another tiler i know stuck the last few cuts with mega strength and when went back the next day they were about half inch lippy from other tiles!!!... I find that amost as funny as the tiler that used spahgetti as spacers and grouted with bits of the stuff left in and it stained all the grout!!

Personally i would wait at least until tiles had grabbed, before grouting.
