This Jesmonite Penetrating Sealer protects and waterproofs your Jesmonite AC730, AC830, and AC930 creations, ensuring a durable and resilient finish.
Formulated to penetrate deeply into the material, this sealer provides invisible protection against water and oils, while resisting stains caused by many liquids and contaminants. It is especially recommended when stain resistance is a priority.
What is Jesmonite Penetrating Sealer used for?
This sealer comes in liquid form, packaged in a one-liter bottle. It is compatible with the Jesmonite AC730, AC830, and AC930 lines. Once applied, it does not alter the visual appearance of the treated surface: the protection remains completely invisible to the naked eye, preserving Jesmonite’s characteristic natural, matte finish.
How do you use Jesmonite Penetrating Sealer?
For best results , apply two successive coats using a high-quality brush, spreading the product evenly. The surface must be clean, dry, and free of any grease before you begin. The second coat should be applied while the first is still slightly tacky, without waiting for it to dry completely. This is important to ensure good adhesion between the two coats and to achieve optimal protection.
This product is useful for protecting Jesmonite creations intended for regular handling or exposure to moisture: decorative trays, coasters, small decorative items, or DIY accessories. It is also suitable for pieces exposed to water splashes or stored in humid environments.
Whether you’re new to Jesmonite or already have experience with this material, technical data sheets and practical tips are available to help you master the finishing steps, choose the right type of sealer for your project, and achieve a polished, long-lasting result.
