Osmo Stone and Terracotta Oil is suitable for the clear impregnation of microporous natural stone with a polished, sanded or break surface and artificial stone in outdoor areas. Especially suited for paving and window sills made of granite as well as limestone and slate. Samples also available.

Clear, satin natural oil impregnation penetrates in the microporous surface and will not form a film on the surface.

Through the impregnation with Osmo Stone and Terracotta Oil, the microporous surface becomes water and dirt repellent as well as stain-resistant.

Dust resulting from screed and concrete surfaces is greatly reduced.

Notes & Tips

• Oils enhance the natural colour of the substrate (permanent wet effect). Trial application is absolutely essential!
• Impregnation may influence the slip resistance of the original surfaces.
• White or very light-coloured stone/surface may yellow slightly as result of the oil treatment!
• For acid sensitive stones like marble and limestone, avoid prolonged contact with acidic liquids such as fruit juice, wine, cola, and vinegar. Prolonged contact with acidic substances can cause etching to acid sensitive surfaces
• Non-absorbent surfaces, such as glass, glazed tiles or ceramic, cannot be treated (impregnated).
• Substrates sensitive to solvents (e.g. plastics such as Plexiglas) must be protected.
• A lack of ventilation leads delays in drying.
• Pre-sealing of absorbent tiles prior to grouting might be possible.
• We highly recommend a trial is carried out first to ensure coloured grouts do not stain the tile.
• Please ensure that the tiles are completely dry before using Osmo Stone and Terracotta Oil.
• We highly recommend allowing at least 7 days for newly laid tiles to release moisture from adhesives before sealing.
• Substrates without a damp proof membrane may take longer to dry.
• Very porous surfaces my require two thinly applied coats of Osmo Concrete oil prior to grouting.
• Following application of Osmo Stone and Terracotta Oil, remove all excess product from the surface and allow 24 hours for each coat to dry before grouting.
• Following grouting, the fully dried and cured grout can then be sealed with one thinly applied coat of Osmo Concrete Oil.
