    I agree, 2.5% sounds a bit slow. Have you tried applying a bit of local heat to see if you can get a bit to cure? A hair drier should suffice, if that works then you know it just needs more time, or more heat

    ok if the mat is damp or a damp area it'll slow it up , 2.5 % sounds right i'd leave it over night as bry say's and see in the morning
    where was the resin from ?? diy/factors etc it should have a date of manufacture on it , it maybe the problem ..
