McLube Mold Sealer


McLube mold sealer is effective on new and seasoned molds of all types. Our sealer will reduce or effectively eliminate porosity on the surface of your mold and leave a high-gloss finish.

  • Color and appearance - Clear Liquid

Application Method:

    The surface to be coated should be free from grease, oil, dirt and all traces of prior release agents.

Any conventional method can be used for application - spraying, dipping, wiping or brushing. Apply three thin, even coats to a fresh mold. Allow fifteen minutes drying time before using the mold.
