Jesmonite Penetrating Sealer 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 our Flex Metal systems, provided excellent protection whilst not affecting the metallic surface. It is also compatible with all our cement composites AC730, ( https://www.polysilshop.co.uk/product/jesmonite-ac730-liquids-powders-kits/ ) AC830, and AC930 and will offer high resistance to all effects of external weathering.
Jesmonite Penetrating Sealer is designed for use with all Jesmonite cement based materials. This includes
AC730, AC830, AC930 and Flex Metal surfaces. The material provides invisible 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.
We recommend that two coats of Jesmonite Penetrating Sealer should be applied to the surface of Jesmonite
cement based materials. 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. Ensure that all surfaces are clean, dry, and free from any grease or oil.
