I lightly rolled and tipped out some birch yesterday, using West 105 resin and 205 fast hardener. Two thin coats a couple hours apart, using a new can of hardener and fresh/calibration checked pumps, so I know the mix ratio was correct.
I have amine blush, which I have not had, at least to this extent in quite a while. Feels like I rubbed the pieces down with bacon grease.
I have been using mostly 206 slow hardener, so maybe that? It may have been the timing of the 2[SUP]nd[/SUP] epoxy coat (1[SUP]st[/SUP] coat just barely tacky), or the warmish and humid shop conditions. Or all three. I haven’t put the shop AC unit in the window for temp and humidity control; that may be a lesson learned.
Before I top coat with spar urethane I need to remove the blush. My usual amine blush removal has been to soapy water wash the surface, changing to clean, uncontaminated rags occasionally, and then alcohol wipe before doing any sanding and top coating.
That has worked, but it doesn’t hurt to ask. How do you remove amine blush?
And yeah, I know, some resins don’t blush, but I have West System pumps and spare pumps and spare-spare pumps, various hardeners and the gallon sized cans of resin. None of that stuff ever seems to run out at the same time, so I just buy a can of whatever I’m getting low on. I can’t bear the thought of amassing a whole nother shelf of resin, hardeners and pumps.
Which brings up a related question. If you had to pick one epoxy resin, hardeners and etc to start with in the shop which one would you choose? Or have chosen if you had known?
