JS cement-based polymer waterproof coating is a waterproof coating made of imported high-performance lotion, modified by various additives, and inorganic powders such as cement. After mixing the powder with additives, a chemical reaction takes place to form a tough waterproof membrane. The membrane has good adhesion to the soil and mortar, which can form a tight, firm and permanent combination with it, preventing the penetration of water.

Product number: LD-2026

Product specifications: 17KG

Construction steps

1. Clean the base layer and sprinkle water on it to moisten it

2. Mix the coating evenly (for at least 5 minutes) to form a paste without clumps

3. When there is no clear water and the base layer is moist, proceed with the first coating

4. After drying, perform a second coat and wait for it to dry

5. After 48 hours of application, a closed water test can be conducted

Common problems during construction

Phenomenon: Pores appear after coating application

1. The base layer is dry and not sufficiently wetted;

2. High temperature construction, surface drying too fast;

3. Uneven mixing and excessive thickness of one-time coating.

Phenomenon: Waterproofing peeling and hollowing occur after construction waterproofing

1. The surface of the base layer has floating ash and sand particles that have not been treated thoroughly;

2. Excessive frequency and fast drying of the surface;

3. Waterproof one-time construction

4. Not blending according to the correct product ratio;

5. Grassroots are loose and not reinforced.

Phenomenon: Sanding occurs after waterproofing construction

1. The base layer is too dry and the wall humidity is low;

2. The coating is not dry, and the maintenance period needs to be extended;

3. Failure to mix and match products correctly.

Phenomenon: Sedimentation occurs during construction

1. Failure to mix and match products correctly;

2. Over usage time.

Matters needing attention

1. The temperature during construction should be between 5 ° C-35 ° C, and outdoor construction is prohibited on windy or rainy days; In case of low temperature and high humidity weather, it is necessary to extend the re coating maintenance time appropriately to achieve the best coating effect.

2. The slurry after opening should be used up within 2 hours.

3. Wet the base surface with clean water before construction, but there should be no exposed water on the base surface.

4. The storage temperature of liquid components should not be lower than 0 ° C.

5. Do not mix dried adhesive with water before use.

6. Before construction, please carefully read the construction instructions.

7. Please use appropriate protective measures during construction, such as gloves.
