Fasted drying rapid set

[jonnyc]

I need to fill in some voids between screed and a ply deck shower tray.
need to get adhesive dry as fast as possible so can put down otl tanking kit .
iam really tight on time .
is there any adhesive that is particularly fast to dry .
was thinking of using warm water to help go off quicker .
but is there anything wrong with using hot water and would this make even quicker.
void is up to 40mm deep and maybe 120 x 70 mm across in places where builder busted out screed to make room for tray.

Tilemaster Trade FlexiRapid White 20Kg, for me is very rapid!!

I've seen rapid mixed with hot water before for a shop entrance. He barely had time to get it out if the bucket! Dunno if it'd effect integrity tho.

BAL Variset is the fastest I've used, just leave out the retarder. Ardex X7R is fast too. The depth of 40mm is thicker than the manufacturers would recommend though.

It's not the going off that is problem.
A very well known trick years ago for rapid repairs was to mix ardex x7 and s16 or assumedly a similar fast and slow set.
can still do this now I am sure.
it is how fast I can it dry that is important.
cannot apply this otl tanking which I guess is similar to ardex tanking until adhesive void fill is completely dry.

Ardex X7R is fast or if you can get a bag from a BAL rep they have re baged varieset that will go in 10 minutes flat

i can pick up x7r first thing .
just hada quick look at varieset. sounds good
key issue being how long it takes to being dry enough to over lay with otl tanking.

White Ultra flexible rapid has fast drying times, ignore the drying times it specifies on the bag. My secret weapon is the old and trusted fan heater

 

[jonnyc]

yes sorry i forgot to say i have fan heaters and heat gun. just not sure whether extreme heat compromises solidity of set

 

[Houston]

Usually just close all the doors and leave heaters on. On the odd occasion we've had heaters blowing directly onto adhesive and hasn't hand any adverse effect

I had an apprentice bring me out a bucket of rapid set that was steaming once. We were tiling a balcony so he thought hot adhesive would help. Was quite funny as I wasn't paying for the sticky, must have put all of three tiles down before it went solid lol.

Ardex X7R is the quickest I've used

 

[The D]

Salt will slow the drying and sugar will speed it up or it may be the other way round LOL.

As already said above X7R is the fastest I've ever used

As above also, X7R, I took a bag back to CTD as I thought there was something wrong with it but then found out its a quick rapid.
It went off in the bucket in about 10mins max.

X7R needs a bit more water than your average RSF

A rep once told me that hot water in rapid set has no effect on bond strength, which is handy.
