Hotline Primo Primer™

Select the green  LEARN  tab for specific product instructions. General usage guidelines can be found here.


Hotline Primo Primer™ is the only traditional primer we recommend for our molds. It creates a very thin layer that always releases, doesn’t destroy the molds’ fine detail, and can be easily removed after firing. 1.5 pound container.

An alternate priming method is to use MR-97 Boron Nitride. It is more expensive than Hotline Primo Primer, but easier to apply and remove.
