Hi guys.I'm newbie for using urethane and pouring cowls. My problem is if every casting which I've pulled out of the mold is too shiny.I would prefer a more matte look. How can I reach if the finished cowls would be matte look?
My resin master was sprayed a black primer. Should I use another brand or not a primer?
The silicone mold was done by 20 shore rubber and I use Smooth-on Vytflex 40 rubber as castings.
Any help would be greatly appreciated!

I've never worked with urethane but have pulled cowls before. Maybe a light coat of a matte spray paint sprayed in the mold before casting might help. If the urethane sets against a matte surface i would think it would come out with a matte surface. Just make sure the coat is thin so you don't lose too much detail. But like I said, I haven't worked with urethane before, so what I've said is just what i think might work.

For a matte look you should have sprayed your master with matte paint before molding.

Do you dust you mould with Talc prior to casting?

Thanks for your replies.It means a lot. I only sprayed with primer my master .I try to spray a light coat of matte paint next time. Actually I thought a primer coat will be good and enough as it had given a matte look already.

I usually dust my mould with Talc prior casting but I only used that when the casting was resin.I've never tried if it's work with urethane as well or not.It sounds good and I definitely give it a try .
