Application Instructions

Surface Preparation:

• Ensure surface is clean, dry, and free from dust, dirt, grease, and oil
• Remove any loose materials or surface contaminants
• Allow concrete surfaces to cure properly before application
• Repair any cracks or surface defects prior to treatment

Application Process:

• No Heating Required: Apply directly from container at ambient temperature
• Mixing: Stir thoroughly to homogenize solution before use
• Application Method: Apply using brush or roller for uniform coverage
• Thinning: If solution thickens, add small amount of diesel as thinner
• Coverage: 500-600 gms/m² depending on surface porosity and conditions

Maintenance:

• Ensure container cap is tightened when not in use to prevent thickening
• Store unused material properly to maintain consistency
