Porous clay, gypsum, plaster and concrete surfaces usually absorb moisture easily, especially in humid conditions. CrystalRock Natural Look Clay & Gypsum Sealer is made to protect these materials without adding unwanted shine or a thick surface coating. It penetrates into the material itself, helping reduce water absorption while keeping the original matt finish and natural texture visible.
This water based penetrating sealer works well for air dry clay crafts, Jesmonite projects, Plaster of Paris decorations, terracotta pots, masonry, porous stone and cement surfaces. Since it does not form a glossy film on top, the surface continues to look natural instead of sealed with a plastic-like layer.
The silane/siloxane formula helps resist moisture, stains, salt damage, mould and mildew while remaining breathable. That makes it useful for both indoor decorative pieces and outdoor garden items exposed to weather changes. It is also low VOC and ready to use straight from the bottle with a brush or spray.
Unlike surface coatings that may peel, crack or flake over time, this penetrating sealer absorbs into porous materials for longer-lasting invisible protection.
