Deep-Penetrating Silane Cream (JT/T 991) | Manta WS120

• 1. Substrate Age (Curing Requirements) To ensure optimal penetration, newly cast concrete must be allowed to fully cure for a minimum of 28 days (4 weeks). Any areas treated with cementitious repair mortars must cure for at least 14 days prior to silane impregnation.

2. Surface Preparation Thorough surface preparation is important for the deep penetration of the thixotropic cream:

• Defect Rectification: Repair visible defects such as honeycombing, exposed rebar, voids and cracks with cement-based repair material.
• Mechanical Cleaning: Utilize a steel scraper, wire brush, or mechanical abrasion to completely remove laitance, dirt, and friable attachments.
• Contaminant Removal: Ensure the substrate is free from grease, oil, and atmospheric pollutants. If formwork release agents or curing compounds were used, their compatibility must be verified via a preliminary test patch. If they impede penetration, they must be completely removed mechanically.
• Moisture Parameters: The concrete surface must be visibly dry prior to application, with a residual moisture content strictly not exceeding 6%.

3. Application Equipment & Method

• Large-Scale Projects: The use of high-pressure airless spray equipment is highly recommended. This method maximizes application efficiency, ensures a uniform thick-film build, and significantly reduces material waste.
• Manual Detailing: For smaller or intricate areas, the paste can be effectively applied using a lambskin roller or brush.

4. Post-Application Protection Following application, the treated surface must be protected from rain, heavy moisture, and extreme weather conditions for a minimum of 24 hours to allow the silane to fully penetrate and complete its chemical reaction under ambient conditions.

Keep in original packaging barrel at 5-45°C, shelf life is 12 months.

This product should be avoided from contact with flowers and other plants, and any items that should not be exposed to the solvent environment should be protected.
