Q & A

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.
