Sienna Studios Acrylic Sealer for Concrete & Jesmonite – Low Gloss, Food Safe – 16 oz

Protect your porous cement, concrete, and Jesmonite pieces with a water-based acrylic sealer designed to highlight details while adding a protective layer. This formula dries clear, forming a natural low-gloss film that preserves the texture of the material rather than masking it.

Ideal for projects like trays, coasters, candle vessels, and decorative objects, the sealer binds to porous surfaces to resist moisture and stains. It is formulated to be safe for indoor use and suitable for outdoor pieces that may face changing weather conditions. The blend is low-VOC and non-toxic when fully cured, with no need for dilution, and it is produced in the USA with maker-friendly ingredients.

Buildable, low-gloss finish

The coating dries to a subtle, clear sheen that enhances surface detail. You can apply additional coats to create a more polished look, or keep a light, natural appearance if you prefer.

• Clear, non-yellowing protection that respects the original texture
• Suitable for heat exposure on candle vessels and pigment-rich cement pieces
• Compatible with Jesmonite and other porous materials

Safe for homes, crafts, and small studios

Once cured, the sealer is food-safe, non-combustible, and low-VOC, offering peace of mind for items that travel from workshop to table. It is designed for everyday use by makers and hobbyists without specialized equipment.

• Indoor and outdoor resilience, guarding against moisture and staining
• Long-lasting clarity that resists yellowing over time
• Ready-to-use straight from the bottle, with no dilution required

Tips for best results

For a flawless finish, apply thin coats and allow ample drying time between passes. Use a clean brush or sprayer to keep particles to a minimum, and store the bottle sealed when not in use to preserve shelf life. Always test a small area before committing to a larger piece.
