Concentrated Siliconate Water Repellent | Manta WS115

1. Substrate Preparation

The surface must be structurally sound, clean, and free of dirt and contaminants. Cracks should be filled level with putty or cement slurry; the substrate must be flat and solid, free from hollow or loose areas.

2. Pre-Dampening & Dilution

Pre-Wetting: Slightly dampening the mineral substrate prior to application can significantly optimize capillary absorption.

Dilution: Dilute the WS115 concentrate with clean water to an active concentration of ≤ 3%. Warning: Concentrations exceeding 3% significantly increase the risk of severe white crystalline bloom (efflorescence) on the treated surface.

3. Application Method

Apply the diluted solution via low-pressure sprayer, brush, sponge, or roller. It can also be utilized in dipping/soaking processes or as an integral admixture in concrete.

Wet-on-Wet Application: For maximum penetration, apply a second coat while the first coat is still visibly wet.

Surface Wiping (Important): When treating dense surfaces such as polished stone or ceramic tiles, any unabsorbed excess liquid must be wiped off immediately with a clean, soft cloth before it dries to prevent permanent alkaline white spots. Allow the treated surface to dry naturally and protect from water for a minimum of 24 hours.

• Highly Caustic (pH 13): This product is strongly alkaline and slightly corrosive. It will aggressively etch and permanently damage glass, plastics, and sensitive plant life. It reacts with metals (e.g., aluminum). Mask and protect adjacent windows, metal fixtures, and vegetation prior to application.
• Over-Application Remediation: If applied excessively, an insoluble white alkaline precipitate will form upon drying. If this cannot be removed by immediate water flushing, aggressive scraping or mechanical abrasion will be required.
• Occupational Health & PPE: Wear chemical-resistant gloves, face shields, and protective clothing at all times. If spraying in enclosed areas, local exhaust ventilation is mandatory to avoid inhaling aerosols. Keep strictly out of reach of children.
• First Aid: Strictly avoid direct skin contact. In case of accidental exposure, flush immediately with copious amounts of water. For ocular contact, flush continuously for 15 minutes and seek immediate medical attention. )
• Winter Reconstitution: At very low temperatures, the active ingredients may crystallize. Simply heat/allow the product to warm to room temperature; it will fully reconstitute into a clear solution without any loss of active performance.

Keep in a clean, dry place. Store strictly at or below 25°C (≤ 77°F) in original sealed containers. Shelf life is 12 months.
