Product Structure

Technical Parameters

Construction Process

1. Substrate Pre-treatment

• Grind and clean the concrete substrate to remove dust; repair depressions and holes, and clear loose sand and other impurities.

• Ensure the concrete substrate is dry (moisture content ≤5%) to meet construction requirements.

2. Primer Application

• Roll-apply the sealing primer with uniform coverage.

• Proceed to the next process only after the primer has dried for 6-8 hours (determined by touch—no stickiness).

3. Application of Aspartic Polyurea Elastic Waterproof Material

• Apply the aspartic polyurea elastic waterproof material via rolling or troweling.

• Control material dosage: 0.8kg/㎡ for a 0.6mm-thick coating.

• Ensure uniform coating thickness, with no missed areas or sagging.

Notes

1. Material Usage Requirements

• Mixing Ratio Control: Precisely weigh Components A and B of the aspartic polyurea roof waterproof coating according to the specified mass ratio to ensure accurate mixing.

• Stirring Specifications: Thoroughly stir the mixed coating until homogeneous to prevent local sedimentation and ensure stable material performance.

• Pot Life: The mixed material should have a pot life of at least 40 minutes. If the viscosity increases during construction, add 5%-10% of the special aspartic polyurea thinner.

2. Pre-Construction Conditions

• Substrate Preparation: Before applying the primer, the substrate must be dry and dust-free to provide a sound foundation for subsequent construction.

3. Finished Product Curing Requirements

• Curing Specifications: Prohibit personnel entry within 48 hours after construction; allow at least 7 days of curing until the coating is fully cured before putting it into use.
