Applications Scenarios

• Exterior walls of buildings,kitchens, bathrooms, balconies, roofs, window perimeters,through-wall pipes & floors,ports, docks, roads & bridges,tanks, water towers, and civil buildings general waterproofing applications

Construction Craft

• Surface preparation: The surface of the base layer should be smooth and clean, free of floating dust, grease, dirt and weathered substances, etc. There should be no phenomena such as sanding, hollowing, or cracking. Before construction, it should be rinsed with high-pressure water and kept in a moist state, but there must be no standing water.
• Proportioning and mixing: The water addition should be 18% to 20% of the weight of the JTB polymer cement waterproof mortar. It can be prepared in advance according to the usage. The mixer should be used to stir until the water and materials are fully mixed. Stir until no dry powder remains and the video state is reached.
• Construction: Evenly apply the adhesive slurry on the base layer. The thickness of each application should be between 3mm and 15mm. The reference usage of 3 mm thickness per square meter is 4.5 kg. The initial setting time is 4 hours and the final setting time is 5 to 6 hours.
• Reference dosage: 1.5-2.0KG per square meter.
• Maintenance: After the initial setting of the construction surface, water (spray) maintenance is required. For horizontal ground, it should also be covered with damp gunny bags, etc. Maintenance should be carried out in an environment of 5-40℃.

Packaging and Storage

Packaging specification: Kraft paper-plastic film bags, 25 kg ± 1 kg per bag.

Storage: Store in a well-ventilated and dry place above 5℃, away from direct sunlight. In winter, prevent freezing.

Safety Specifications

Wear a dust mask, safety goggles, and protective gloves during application.
In case of skin or eye contact, rinse immediately with plenty of clean water. Seek medical treatment promptly if symptoms are severe.
