This is my 1st time building a board - I started glassing and the "resin" part of the epoxy (not the hardener) is very think.  I would say it is the consistency of slightly crystallized honey.  It is to the point where it will not pump out of the container (I have to pour).  I am glassing in my basement (winter time in PA, USA) which is probably around 55ish Fahrenheit.  I am guessing for my next layer I should warm up the epoxy (I am thinking of putting the bottle down into warm water).  What is the ideal temp for the epoxy when I apply it?  Also - the epoxy cured nicely but is okay to let it cure at this temp?  Thanks.

you could just micro wave the resin for 5-10 seconds. It shouldn't be a problem if you don't over heat it. If you are scared of it getting too hot ... just heat it for 2-3 seconds at a time until it is viscous enough to work with

I try to aim for 70°F, use a spaceheater I borrow from a neighbor to heat my glassing area.  my RR cures to touch in about 4 hours in these conditions.  at 55°F its gonna take your epoxy quite a bit longer to cure even if you preheat it.

Thanks for the tips -- I have been working on the board only the weekends -- so I am okay with it if it takes awhile to cure -- one weekend I lam it and then a week later I work on it again.  The main reason I want to increase the temp is so the epoxy is workable.  Thank you both!

im in Pa also doing it in my basement. i use a small space heater on high. while i go around making sure the glass and blank is ready the RR heats up and workablity is great. i also use the X55 accelerator to get the cure times back down.

Brings me back to the first time I ever built an epoxy.  The resin wasn't very good. Lot's thicker than what our stuff is today.  Anyway it was a cold day in winter and I went to pour the resin and it wouldn't pour at all.  I mean it was like it was gelled or something.  Lots of years later it just seems normal to stick the stuff in a microwave for a few ...

Try and bring the room temperature up if you can. The problem with sticking it in the microwave is that it cools back down fairly quickly if it's cold enough.

Thanks for all the tips.  And a big shout out to all the Amish out there!

It may kick OK in colder temperatures than recommended but watch for blush.  Above 65 is the recommended minimum and the resin should be allowed to cure for 24 hours at that temperature if I recall correctly.

using rr epoxy right now. Got it shipped from Pa to Ca. I had to do a warm water bath to make it workable. Was rock solid when it was shipped. About 120 degree water it softened up quick. Def suggest warming that room up before you work until well after you are done laminating. Good Luck!
