First time builder here...
I have applied two coats of epoxy to the hull. The first coat I applied with a 4" roller and brush. The epoxy ran during the cure. So, I sanded the runs out with 120 and a good finish sand with 220. Wiped down with denatured alcohol. Hull looked pretty good. I applied the second coat with a brush and pulled it as thin as I could with a plastic spreader. I thought I had applied too thick a coat before, so if I could really spread it thin, it would cure flat. Nope, ran again, but not as much. Now it is back to sandpaper.
Question; is this running problem just part and parcel of applying expxy to a non flat surface ?? I have a friend that builds with plywood, he said that he always pre-coats prior to assembly. I suppose that we could have pre coated the planks after putting them together and before drilling for the wire up, but with the 5 day schedule we were on in the building class, no way we would have gotten done in time.
So, am I doing something wrong, or is the simple way to avoid this extra work is just to pre coat ??
