Looking for a sealer that protects clay, gypsum or plaster without making the surface shiny? CrystalRock Natural Look Clay & Gypsum Sealer is a water based matt penetrating sealer made for porous indoor and outdoor surfaces.
It soaks into the surface instead of forming a plastic-like coating on top. This helps protect against water, sweat, stains, salt damage, mould, mildew and weather exposure while keeping the original colour, texture and natural matt finish.
This sealer is suitable for air dry clay, gypsum, Plaster of Paris, Jesmonite, concrete, mortar, masonry, brick, clay pots, unglazed terracotta, sandstone, limestone, marble, granite and natural non-polished porcelain tiles. It is a good choice when you want invisible protection without peeling, flaking or gloss.
Why This Clay & Gypsum Sealer Helps?
- Keeps a natural look: Leaves no visible film, gloss or artificial coating.
- Repels water: Helps reduce moisture absorption on porous surfaces.
- Helps resist stains: Protects against common oil and water-based stains.
- No peeling or flaking: Penetrates into the surface rather than sitting on top.
- Easy to apply: Ready to use with a brush or spray. No mixing needed.
Best Uses:
- Air dry clay crafts and models: Helps protect finished clay items from moisture marks.
- Gypsum and Plaster of Paris pieces: Useful for decorative pieces, moulds and handmade items.
- Clay pots and terracotta: Helps reduce water absorption while keeping the natural clay look.
- Concrete and masonry surfaces: Suitable for walls, floors, garden features and outdoor surfaces.
- Natural stone surfaces: Can be used on porous marble, granite, limestone and sandstone.
