it stays pliable for about 90 minutes give or take for the mix ratio...then it starts to set...24 hours is plenty but the standard 2 prt GS sets in 18 hours completely...although there is a bit of flex in it still......to make it harder add more of the blue...to make it stick better more of the yellow...older stuff may get tempramental to work with so make sure you knead it thoroughly before trying to model it...and remove any lumps of the stuff that won't mix as these will make sculpting and finishing your peice a pain in the bumm....
