Hi, I have used EL2 resin with slow hardener to coat the inside of a moulding with the intention of sanding and polishing it to give it a nice finish on both sides, its been 4 days now and the surface is still not hard enough to sand.

When I have done this before with the fast hardener it is good to sand after 24 hours or so,

Is it just a matter of leaving it for longer, or have I messed up somehow?.

Any Ideas,




Drew.

I think I will try wetting the hardener cup before I weigh out. Should retain the same amount. Would weigh in 1, but it starts to gel too fast.
