Mixing epoxy on my worktable

I can't imagine I am the first one who thought of this, but I haven't seen this anywhere else.

A while ago I saw at a stall at our central bus station someone selling masking tape real cheap. So I bought 20 rolls...
A few days later I was at my worktable, ready to mix some epoxy for a project. Looking about for a piece of carton or paper to mix it on, I couldn't find any. Annoyed I was about to go upstairs to see if we had some lying around, my eye fell on the pile of masking tape rolls, and a light went up.
I cut a few lengths of tape and put them on the table, two side-by-side, 3 layers. I mixed my epoxy on it, and applied the epoxy on the project. When the epoxy had cured I lifted the masking tape of the table and threw it in the bin. No mess, and no pieces of epoxy smeared paper or carton lying about!
The number of layers I lay down depends on the epoxy I use; slow curing or faster curing. For 5 minute epoxy I lay 3 layers. For 30 minute epoxy I use 4 layers; the epoxy might seep through the paper. Hasn't happened yet, but I don't want to find out when it's too late.

Great idea

I use a Resi-Mate mixing mat myself. The unused epoxy just snaps off the mat once it's cured. I expect an old cutting mat would work the same way, but I haven't tried it.

Just save all the junk mail that wanders into the house. I guarantee your stack of mixing sheets will grow faster than your consumption.

The tape is certainly a slick trick and very doable. But I for one would be annoyed at the time it would take to prep the mixing area. Also the masking tape is useable for so many other things even if it was cheap in your case. The unwanted advertising junk mail? Not so much.

I've been using, for years, a sheet of polyXXXX (don't know what type) plastic I bought at the auto supply for mixing Bondo. Let the glue cure and then pop it off. It can be moved to the work without flopping and dropping the goop all over, also you don't need a clear spot on the work table...which applies to me.

I use pages from Model Aviation that I have already read.

The best "mixing/application sticks" that I have found are old hotel key cards.

I spent 173 nights in hotels last year (travel a LOT in my business). I usually walk out with at least one key card in my pocket and I have been doing this for years.

I throw the old cards in a drawer and then use a pair of heavy duty scissors/shears to cut the cards into strips. I use a strip as the mixing and application stick and then toss it into the trash.

The full cards make great tools for smoothing and leveling fiberglass and drawing excess resin off the project.

polyethylene probably, or nylon. Damn little sticks to either, which is why paint roller pans are made from them nowadays.

The reason I dislike loose pieces of paper/carton/plastic etc. is that they can move about on the table, and you usually need two hands to mix; one hand for themixing, and one to hold the base in place.

I've been using a 4x4 piece of glazed ceramic tile. You know, the cheap kind thats on everyones bathroom walls. Heavy enough not to move around and I can then move it out of the way before I mistakingly stick my hand in it. After the mix has dried, the epoxy will just peel off. Any residue can be quickly scraped off with a single edge razor blade. Works just as well for mixing CA and baby powder except its a bit harder to get off.

I use little medicine cups. They are the kind that nurses pass meds in at the hospital. They are graduated in mL, drams and oz. For mixing sticks I use the little wooden sticks that come from the poo tests we get at the office. It's all disposable. When I run low, I just grab a few more from the hospital/office.

I use post-it notes, paper from the printer, old envelopes, tape on the workbench, med cups.

I also use manuals from old models. Tear off a sheet when you're done with it. Kinda like when we were kids and had an outhouse - Sears catalog did the trick then. (Not the Wish Book - you had to keep that around for birthdays!)

Back when I was a gunsmith my mentor would use an empty Copenhagen can. Once you were done and the epoxy hardened you could just twist the can and the hardened epoxy blob would just pop out.

I preferred a Folgers coffee can lid.

Now I know why the cost of medical supplies are so high in hospitals.
