Product Features

• Superior Water Resistance: Forms a seamless, impermeable layer that prevents water from seeping through, ensuring long-term protection in damp or high-moisture environments.
• Eco-Friendly Formulation: Water-based formula with low VOCs (Volatile Organic Compounds), making it safe for indoor and outdoor use without compromising on performance.
• Durability: Exceptional resistance to wear, abrasion, and UV degradation. Ideal for both indoor and outdoor use, even in harsh weather conditions.
• Non-toxic & Low Odor: No harmful fumes during application, making it suitable for sensitive environments like homes, schools, and healthcare facilities.
• Flexible & Crack Resistant: Retains flexibility after curing to accommodate movement or expansion of the substrate, preventing cracks and deterioration.
• Easy Application: Can be applied with a brush, roller, or spray, offering convenient application on large and small surfaces.
• Quick Drying Time: Cures quickly, allowing for faster project completion without compromising finish quality.
• Versatile Use: Suitable for a wide range of substrates, including wood floors, decks, concrete, metal, and masonry surfaces.

Storage & Transportation

1.During transportation, avoid rain exposure, direct sunlight, pressure, and collisions. Keep the packaging intact.
2.Store in a well-ventilated, dry, and cool place with a storage temperature between 5°C and 35°C.
3.Unopened products have a shelf life of 12 months

Construction Requirements:

1.Clean, Dry, and Free of Contaminants:
• Surface Cleanliness: The surface must be free of dust, dirt, grease, oils, waxes, and other contaminants that could prevent the coating from adhering properly. Use a suitable cleaner or degreaser to remove any impurities.
• Moisture Content: The substrate should be completely dry before applying the coating. For wood or concrete surfaces, the moisture content should be below 12%. Excess moisture can affect adhesion and curing.
• No Standing Water: Ensure that there is no standing water on the surface before applying the coating.
2.Surface Preparation:
• Wood: Sand the wood surface to remove any old finish, stains, or rough spots. The surface should be smooth and even to allow the coating to adhere properly.
• Concrete: Concrete surfaces should be clean, free of laitance, and free of any old coatings. If applying over a previously coated surface, ensure it is fully intact and not flaking or peeling. It’s often recommended to etch the surface lightly with an acid solution or use a concrete surface preparation product for better bonding.
• Metal: Clean the metal surface thoroughly, removing rust, oil, and other contaminants. A wire brush, sandpaper, or power sander can be used for rust removal. For galvanized metals, a light abrasive sanding or etching is recommended to ensure proper adhesion.
• Masonry: For brick or stone, ensure the surface is dry, clean, and free of efflorescence (white salt deposits), which can hinder adhesion. A surface primer may be needed for optimal bonding.
3.Smoothness & Texture:
• For maximum adhesion, the surface should be smooth or lightly sanded. Rough surfaces may require extra coats of the coating to ensure proper coverage.
• In cases where extra adhesion is needed, consider using a primer designed for the specific substrate.
4.pH Levels (for Concrete and Masonry):
• The pH level of concrete and masonry should fall within the range of 7 to 10. High pH (alkaline) surfaces, especially those freshly poured, may require a primer to ensure the coating adheres properly.

Application Process

1.Surface Preparation: Clean and dry the surface to be coated. Remove any dirt, oils, and old coatings.
2.Application: Stir the coating thoroughly before use. Apply one or two coats using a brush, roller, or spray, allowing each coat to dry completely before applying the next (typically 1-2 hours).
3.Curing Time: Allow 24–48 hours for full curing before exposing the surface to heavy use or moisture.
4.Clean-Up: Clean tools and equipment with water before the coating dries.
