STONE SEALER
STONE SEALER
Revitalize and Protect Your Natural Stone with a Durable Satin Finish
Unprotected stone and outdoor tiles lose their visual appeal due to persistent UV exposure and moisture ingress. Over time, the sun's rays can cause surfaces to dull, while moisture leads to unsightly white salt stains and the growth of green mold. Rhinoluxe Stone Sealer acts as a revitalizing shield that preserves the natural chromatic depth of masonry. It penetrates deep into the surface to prevent fungal growth and efflorescence to keep your outdoor spaces looking fresh and clean. This professional-grade solution ensures your stone and concrete surfaces stay beautiful through-out the seasons.
Key Benefits
- Superior UV Stability. The advanced formula resists yellowing and brittleness caused by constant sun exposure to maintain a clear finish.
- Impedes Fungal Colonization – The acrylic membrane creates an inhospitable environment for organic spores to prevent black algae growth.
- Neutralizes Chemical Staining – High-density polymer resins block the penetration of domestic oils and food fats in braai areas.
- Reduces Surface Efflorescence – Breathable film technology allows vapor escape while stopping liquid water from migrating salts to the surface.
Technical Overview
Rhinoluxe Stone Sealer SB is an industrial-spec Pure Acrylic Solution polymer designed for high-performance protection of porous masonry. The solvent-based delivery system carries the resin deep into the structure of the stone rather than resting on the surface. This mechanism creates a durable, low-gloss satin finish that stabilizes the substrate against medium-duty wear and tear. Rhinoluxe Stone Sealer is a high-performance, resin-based sealer which highlights the natural colours, giving it that sought-after "wet look". By filling these pores, it creates a barrier that stops spills and moisture from soaking in, making your floors much easier to clean and maintain.

Technical Guidance
To get the best results, ensure your stone is completely dry, ensuring the substrate moisture level is below 8% to prevent the formation of white, cloudy blooming as even slight dampness can cause the sealer to turn white. You should avoid applying the product in the heat of the midday sun, which can cause the resin to dry too quickly and create tiny bubbles. For extremely smooth surfaces apply the initial coat thinned 10% with Xylene to maximize the mechanical anchoring of the polymer to execute deep penetration. Always clean your surface thoroughly to remove dust or old wax that might prevent the sealer from sticking. Wait at least 4 hours before applying a second coat to ensure the first layer has cured properly. Using a soft brush or a high-quality Mohair roller will help you achieve an even, streak-free satin finish.

Questions & Answers
Have a Question?
-
How much do I need to cover 1000 sm
8-10 square metres per litre for the first coat and 9-11square metres per litre for subsequent coats. You would need 11 x 20L Stone Sealer for a 2 coat application.
-
Can it be used on the exterior of a brickface house on the coast?
Yes the Stone Sealer can be used on a brick face house in coastal areas.
-
Is the finish glossy or matte?
It provides a low to high gloss finish depending on the surface porosity across the Western Cape.
-
How often should I re-apply the sealer?
Most outdoor surfaces benefit when you apply a maintenance coat every 24–36 months. High-traffic areas in direct sunlight require attention sooner. Frequent maintenance ensures you maintain the maximum level of UV protection and natural colour depth.
-
Is the sealer compatible with old wax coatings?
No, applying the sealer over old wax or incompatible products causes dissolving or lifting. You must remove old coatings completely if a solvent test patch shows a reaction.
-
Do I need to thin the product before use?
We recommend thinning the first coat by 10% with Xylene. This reduces the thickness of the liquid, allowing it to soak deeper into the stone's pores for maximum adhesion before the full-strength second coat is applied.
-
What happens if it rains right after application?
Rain within the first 4 hours can ruin the finish. If the sealer has not had time to dry, the water will penetrate the wet resin and cause it to peel or turn white, requiring a full strip and re-application.
-
Why is a resin-based sealer better than water-based?
Resin-based sealers offer deeper penetration into the mineral structure of the stone. This creates a more permanent bond and a richer color enhancement that water-based emulsions cannot match, especially in high-traffic outdoor areas.
-
Can I use this on interior cement floors?
Yes, you can use this product for interior cement screeds and slate floors. It provides a low-maintenance finish that protects your indoor floors.
-
How long does stone sealer take to dry?
It takes 1–2 hours to become touch-dry in normal weather conditions. You should wait at least 4 hours before walking on the surface or applying a second coat to ensure the resin has fully bonded.
-
Does stone sealer make the floor slippery?
No, it maintains a safe grip when applied correctly. While it provides a beautiful satin sheen and enhances the color of the stone.
-
Is stone sealer safe for braai areas?
Yes, it is highly recommended for braai areas. The sealer creates a barrier that prevents grease from staining the porous stone, making it much easier to wash away spills after cooking.
-
Can I apply stone sealer to a damp patio?
No, the surface must be dry before you begin application. Trapped moisture under the resin causes a chemical reaction known as blushing, which results in an unattractive, cloudy white appearance that is difficult to remove.
-
How much area does 5 litres of stone sealer cover?
5 litres covers 40–50 m² for the initial application on most stone surfaces. Porous materials like sandstone may require more product, while denser tiles like slate will allow the sealer to spread further during the second coat.
