Anwer the Question Drew...Where does the water, we put into the powder go ?

I did.
Just like it does with cement based addy, it acts as the catalyst for a chemical reaction. it does NOT "dry out", it cures. And this stuff cures fast.
I suppose you also think that Concrete sets when all the water somehow dries up?

Why don't you just admit you were wrong, instead of scrapping the bottom of the barrel for reasons to still say you are right?

A decent proportion of water, we must agree does soak into the substances it makes contact with....it dosn't magically disappear, it defies laws of chemistry,if fast setting adhesives or plasters are used the water content needs to evaporate/dissipate, before totally cured.....so to grout them before proper set time, is to trap unwanted moisture......Gaz

are talking about tiling on plaster or "paper" and tiling with rapid adhesives or both :whatchutalkingabout Drew it may be a usfull product ideal for plasterboard but your not tiling to plaster with plasterboard which is my point

Suppose the easiest way to answer this question is to put some of the stuff on a plaster wall and scrape it off straight way. If it leaves a stain on te wall as I suspect it would than water will disipate into the substrate to a certain extent, chemical reaction or not!

This comes along the lines of a previous thread about removing tiles from plasterboard walls. If the tiles and adhesive were only stuck to the paper lining, why does it take the plaster with it when you take the tiles off? Seems to me the slower adhesive sets - either by reaction or dispersion - the more likely that plasterboard will come away with the tile. This is an observation based admittedly on my very short experience of tiling. I would be interested in other peoples opinions and experiences.

it sounds to me like a few hot heads on here!
coooooooooool down boys!

You should look at using Nicobond Unique when tiling onto plaster, or plasterboard. It's gypsum based, so no need to worry about any reactions.
It also sets full in 1 hour.

this stuff could be handy....have you used it much, if so...how have you found it..Mark.

i use it all the time but its not recommended for wet areas. i spoke to the main rep at a trade evening and he said it will be ok for domestic showers. great gear to use and holds large tiles up without battens. but beware you have to be pretty fast with it.

so whats the working time on unique? whats the cost as well?

I honestly do not know why you seem to have a problem wth this.
How long did you used to wait before grouting floors you laid with Bal Rapid set, that says it can be grouted after 2 hours?
Did you wait until that was 100% cured, or set enough, according to manufactures spec's, to grout?

This stuff sets fast. The makers, ho have no doubt spent a fortune developing it, say it can be grouted an hour. I think they know far more about it than you or I.

I will continue to follow their advice, and my experience.

I use it pretty often. It is great to work with. Much easier to trowel onto walls than cement based addy.
You have about 40 minutes working time with it, but you need to keep the bucket you mix in clean.
If you do not, the mix goes off quicker, because the addy that has already started to go off causes the new mix to go off faster than it should. Nothing to do with evaporation, Gaz.

As I said above, around 40-60 mins, but only if you keep your bucket clean of old mixes.

I pay just under a tenner for a 15kg bag.
One thing I will say, it does not cover as much as the 10-15sqm they claim.
I would say more like 6-8sqm per bag.

I was told the same, fine for domestic showers.
I use their Tilers Grout too, which is waterproof, not just water resistant. And if it's a power shower I add a bit of Enhancer 2002 just to be safe.

I did have times Drew where I would grout floors after fixing with rapid too early,this became a problem with the grout being tainted and drying patchy in colour, I wouldn't grout as soon as the tiles stopped moving I would grout the following day..but I would always err on the cautious side...it's in my nature...never one to fly in and out, if the job needed more time I would spend it,the next job would always be there ready for when I was.......Gaz

Kinda defeats the purpose of using Rapid set then.
Why didn't you use the same cauton when using cement based addy to fix and fix to plasterboard?:huh2:

I always prime the walls, wet the back of the plasterboard before dotting out and fixing.The face is then ready to tile when board is set,prime the face for cement based,and not for tub gear.Rapid set for me , had the sole purpose of enabling people to walk over the floor sooner than slow set,or to enable you to fix tiles onto a batten to support tiles above, and then remove in faster time span complete tiling below....Gaz

So do you think all these manufacturers are wrong when they say ,
"grout after 1/2/3 hours" ?

Or is it just Nicobond Unique you have a problem with?

I think genuine points have been mentioned on both behalfs here lads so can we let this drop now please...many thanks......
