1. Packaging and Logistics    Delivery Date Guarantee

2. Product Description

Polymer-cement waterproof mortar is a high-performance waterproofing material composed of premium cement, carefully selected polymers, and various additives. This product boasts excellent waterproof performance, strong bonding strength, and superior crack resistance. It is easy to apply and can be directly spread onto substrates such as walls and floors, forming a robust waterproof layer. The product exhibits outstanding water resistance and remains firmly adhered without flaking or crumbling even after prolonged immersion. It is suitable for waterproofing projects in various types of buildings, including roofs, bathrooms, basements, and more. With stable performance and a long service life, this product effectively prevents moisture penetration and ensures the safety of your building. Choose our polymer-cement waterproof mortar to provide reliable protection for your waterproofing projects.

3. Scope of Application

1. Concrete reinforcement of building structures

2. Reservoir dam and port handling

3. Hot water pools, landfills, chemical warehouses, chemical tanks, etc.

4. Concrete repair for road surfaces, bridge decks, tunnels, and culverts

5. Treatment of roofs, bathrooms, and basements in industrial and civil buildings

6. It can be directly applied to damp substrates and exhibits excellent adhesion to a variety of base materials.

4. Product Features

1. Non-flammable and environmentally friendly.

2. Simple and quick construction, wide applicability, short construction period, low cost—just add water and mix before use.

3. Construction on large-area surfaces that are damp but free of visible water.

4. Can be directly applied to both the water-facing and non-water-facing surfaces, as well as on damp substrates.

5. Contains special active agents that can penetrate the substrate and form a crystalline layer.

6. It can bond with a variety of materials such as brick, stone, concrete, and cement mortar, forming a strong, integral bond between the substrate and the waterproofing layer with high adhesion.

7. At high temperatures of 100℃, there is no cracking, peeling, or flaking; at low temperatures of -40℃, there are no changes.

8. The setting time can be freely adjusted: the more water added, the lower the temperature, the higher the temperature, and the poorer the ventilation, the longer the setting time; conversely, the shorter the setting time.

7. Instructions for Use

After the base layer has been properly treated, apply a reinforced layer to the architectural node areas. The reinforced layer can be applied by brushing on a coating or by adding and embedding mesh fabric for extra strength. Once the node areas have been reinforced, apply a primer coat. When preparing the primer, mix components A, B, and water according to a ratio of 1:1.2:1, and stir thoroughly until well combined. Use a scraper to spread the primer evenly over the substrate surface. After application, carefully inspect the surface to ensure that no bare substrate is exposed.

After the primer has dried and hardened, proceed with large-area coating application. The coating material should be thoroughly mixed according to the specified mixing ratio. The number of coat applications can be carried out based on design requirements, but it is recommended to apply at least three coats. During application, each coat should be applied in the same direction, yet each subsequent coat should be applied perpendicular to the previous one. Allow an interval of 8 hours between each coat, taking as the criterion for completion the point when the coating film has fully dried and hardened.

If a rigid protective layer is required for the waterproofing membrane, it must be applied two days after the final coat of coating has been completed. If ventilation is poor or construction is carried out in winter, the waiting period should be extended accordingly.
