Ceramic Sealant for Fired Porous Clay, Creating Invisible Waterproof Protection on Unglazed Pottery
Ceramic sealant helps protect unglazed pottery from water and stains while preserving the surface's original look and feel. Its water-based quartz formula seals stable, intact fired porous clay, including bisqueware, fully fired unglazed pieces and fired underglaze.
Apply by dipping, spraying or brushing to suit the shape of your piece. Start with a clean, completely dry surface, apply only one coat and wipe away excess before it pools. Allow 24 hours before handling, then clean treated pieces promptly with mild dish soap and water.

Frequently Asked Questions
Can this ceramic sealant be used on glazed pottery?
Use this ceramic sealant on exposed fired porous clay, rather than intact non-porous glaze. Suitable areas include unglazed surfaces, bisqueware and fired underglaze. The clay must be stable and intact.
How do I brush or spray the sealant onto pottery?
Shake the bottle, then brush or spray one coat onto clean, completely dry pottery until the surface no longer readily absorbs it. Wipe off beads and excess liquid, avoid pooling and allow 24 hours before handling. Wear gloves and cover your arms during application.
Should I choose the 4oz or 8oz bottle?
Choose the 4oz bottle for 118mL or the 8oz bottle for 237mL. As a guide, a mug exterior uses approximately 5mL and a dinner plate approximately 10mL; more porous pottery absorbs more sealant.
Will this sealant change the appearance of my pottery?
This ceramic sealant creates an invisible finish that preserves the pottery's look and feel. Apply only one coat and wipe away excess, since pooling or over-application can cause discoloration.
How should I clean pottery after sealing it?
Clean sealed pottery promptly with mild dish soap and water, or use a dishwasher. Avoid harsh detergents and abrasives, and wash off substances soon after use to help prevent staining.
How should I store the ceramic sealant?
Store the ceramic sealant in a cool, dark cupboard and use it within one year of purchase. Protect it from freezing, which can reduce its effectiveness; test a small area for water repellency before treating a whole piece.
