Jesmonite Penetrating Sealer is designed for use with Jesmonite cement based materials AC730 and Flex Metal Gel Coats. It provides protection against water and oil, and also provides stain resistance against many liquids and environmental contaminants. We recommend its use where stain resistance is a priority.
This is specifically used when the sealing effect must be invisible (i.e. not a coating) but where good water resistance and stain resistance is required. It is particularly suitable for Jesmonite's Flex Metal systems, providing excellent protection whilst not affecting the metallic surface. It is also compatible with Jesmonite's cement composites AC730, AC830, and AC930 and will offer high resistance to all effects of external weathering.
We recommend that two coats of Penetrating Sealer should be applied to the Jesmonite AC730 or Flex Metal Gel Coat surface.
The second coat is applied once the first coat is touch-dry. Do not allow first coat to dry completely before applying the second coat.
Penetrating Sealer should be applied with a high quality brush spread evenly across the material surface or high quality dense foam roller. Ensure that all surfaces are clean, dry, and free from any grease or oil.
