Primo is the newest formulation of primer on the market. Primo Primer fires to 1550 degrees F (843 degrees C) and higher.
Glass does not stick to the shelf and primer does not stick to the glass. It is the easiest primer to clean up after firing - simply brush the shelf or wipe with a damp sponge. Primo works exceptionally well as a separator on kiln shelves and preserves great detail in casting moulds.
Sounds too good to be true? It's harder to mix than standard primers and a bit finicky in application - we provide full instructions however - we use it ourselves and think its the best choice.
