Do I need to scuff up or do any other prep work to put on a second coat of epoxy over the 1st one, or do I just lay it on as is?

Thanx

I only use a single coat.:huh:

I normally do only one but the 1st coat had a few flaws that I was thinking a second coat would take care of.

It varies with the different manufaturers of epoxy, but generally, if it's within a day or so, then just apply it, more time between like 2 days or 3 then I would scuff it.

I always scuff between but I take my time and never get the second coat within a day or so, so that is why I scuff. If I had the choice I'd recoat within 24 hours.

I like to litely sand with 800 grit. It helps take off any high spots as well as give a better bond, and its quick and easy.:D

As Slipknot does, if I'm gonna 2 coat, I try to get the second on within 24hours.
