What prep should I follow after buffing, sanding, or stripping the mold?
Sanding, heavy buffing and stripping can open pores of a mold, allowing un-reacted styrene to bleed out of the mold during production. This can occur in seasoned molds as well. Once the mold has been buffed, sanded, or stripped, and all foreign matter removed, clean the mold with a high quality mold cleaner following the recommended application procedure. Then apply a high quality sealer and release agent following the manufacturer’s instructions.
