«Polymer Modified Cementitious Waterproof Coating» JC/T 984-2011

1. Excellent workability and cohesion, with high bonding strength;

2. Good resistance to bending, pressure, and cracking; strong anti-permeability;

3. Resistant to aging, temperature extremes, and chemical degradation;

4. Easy to apply, can be used on wet (non-saturated) substrates, with excellent long-term performance;

5. Eco-friendly and safe, environmentally friendly.

1. Prior to applying the waterproof coating, the base layer must have a mix ratio of soil and coating strength not less than 80% of the design value.

2. The base layer should be flat, firm, clean, free from floating debris, and free of cracks or holes. If oil contamination, mold, or similar issues exist, cleaning and repair treatment is required.

3. Before application, the base surface must be moistened by watering thoroughly. Construction can proceed once no standing water remains.

4. When applying polymer modified cementitious waterproof coating, use a mechanical trowel mixer to ensure even spreading. Manual troweling is not allowed. Application time should be extended by 2–3 minutes compared to conventional coatings. It is recommended to pre-trowel for 2 minutes, pause for 2 minutes, then re-trowel for another 2 minutes to achieve uniform coverage. Avoid over-application—adjust troweling speed according to the rate of application.

5. For critical areas such as pipe roots, leak points, structural corners, and other fine details, reinforcement treatment is required. Around pipe roots, the base layer should be prepared with a 1 cm wide and deep groove. Apply one coat of polymer modified cementitious waterproof coating into the groove, press in one layer of mesh fabric, then apply another coat of coating and finish with troweling.

6. During application, the coating thickness must be consistent across all layers, avoiding uneven or thin spots. Each layer should be tightly bonded; continuous application is preferred. If joints are necessary, use a staggered joint pattern, but maintain a minimum distance of 200 mm from any corner. Joint overlap width should be no less than 100 mm, and each layer must be applied in sequence.

7. After curing, perform maintenance using clean water (do not use wastewater), maintaining a temperature above 5°C.
