I have started using HHG for my construction projects. It is working fine and I have not had a problem, but, I wonder: After I use the glue I turn it off and it may be two days later when I use it again. After sitting for that period of time a skim forms on the glue. I reheat and remix the skim into the glue and add a bit of water to thin things down to a usable consistancy.
At what point should more glue be added to the pot? I watched a youtube demo by a builder who gave very good visual checks to see if the glue is usable and I have followed his procedure with no major problem but it seems to me you would have to add glue at some point.
Just wondering how most of you decide when to add glue?
