How much catalyst do i use, and what type?
You would use standard MEKP catalyst as supplied with product, it is actually the same catalyst you would use with Polyester Resins at an addition of 2% ie 20ml per litre.
After applying Durabuild primer how long do i have to leave it before i can sand it down on my mdf plug?
It is best to leave the material overnight before sanding down to ensure full curing has taken place.
