Bal Fastflex Drying time

[coco3107]

Hi guys been reading the forum for a couple of weeks, never realised there was so much to tiling but it has been a great learning curve thanks!
I am doing a bathroom in a flat I own which is chipboad on joists screwed down, then as you guys seem to recomend, 12mm wbp ply at 100mm centres screwed and glued, then the primer supplied with the underfloor heating wire screeded in using 2 part fastlex as recommended by Bal technical. The problem is I mixed it as per the instructions and laid it with a flat trowel to screed the wire in, but 5 hours later it is still not dry? Should I be worrying? Thanks in advance Colin.

Never used fastflex.

Don't forget you can always use 6mm hardi backerboards for flooring too.

As I said, I have never used fastflex so I couldn't say from any experiance how long it took to set.

If it's only been 5 hours I wouldn't worry, leave it over night and see what it's like then... should be set most probably.

Its going to depend on the tempreture of the room and the thickness the fast flex was laid . Was it mixed properly ?
I used some yesterday and it was still soft after 5 hours.
If its not set by the morning then something is wrong.

According to this setting time is 3 hours
