David = Love likely got it right - epoxy can be very sensitive to having the = exact proportion of resin and hardener correct. When mixing medium and = large quantities of epoxy, volumetric measurement methods are usually = sufficient. But with smaller quantities it is best (pretty much = required) to weigh the proportions on an adequate scale to get the = proper mix. Bernard is correct that epoxy can require several days to cure = completely, but most epoxies cure to about 98% of their final hardness = in less than a day. Whereas one day should be sufficient time for most epoxies to cure = adequately in the application you describe, when I have epoxy-repaired = bridges, I have let the epoxy cure for at least two days - preferably = longer.=20 I am not familiar with the properties and cure times for Araldite 2013. = That info should be available from the manufacturer.
