Protect your ceramic creations with Clay Coat - a quartz ceramic sealant that makes unglazed areas completely waterproof and stain resistant. With its non-toxic, all-natural formula, it creates an invisible layer of protection that is microwave, dishwasher, and oven safe. Directions for use: Begin with bisque or fully-fired ware. Ensure that the surface is completely dry and free from dust and grease. Surface must be intact (not chipping or flaking). 1: Shake bottle before use. 2: Apply. While wearing gloves, spray/dip/brush one even layer on to surface until it no longer readily absorbs the sealant. If sealant gets on a glazed area, wipe off with paper towel. Apply only one coat. 3: Let cure. Allow 24 hours before handling. Use within 12 months of purchase. Store in a cool, dark place.
