Applications

Suitable for waterproofing in kitchens, bathrooms, warehouses, basements, etc.

Product Features:

Complies with National Standard

Strong impermeability — no water penetration

Nano-crystalline dense sealing forms a 3D high-strength waterproof layer

Colorful glossy paste ensures full coverage with no missed spots

Good flexibility — bridges cracks up to 1 mm; strong adhesion to mortar forms a tight, firm bond

Usage Specifications:

Substrate preparation: Clean the substrate thoroughly — it must be flat, firm and hollow-free. Fill pores and pinholes with cement mortar; repair internal corners and pipe roots into oval shapes. In high temperatures or on dry substrates, dampen thoroughly with clean water until no standing water remains.

Mixing: Pour the liquid into a clean bucket, then slowly add powder while stirring (liquid : powder = 1 : 2-2.5). Mix thoroughly until a uniform, lump-free paste with no sediment forms. Rest for a few minutes, stir lightly again, then use. (Electric mixer recommended for best results)

Application: Apply directly to the prepared substrate with a brush or roller — no missed spots. If air holes appear, brush repeatedly to release air. After the first coat is surface-dry (not tacky), apply a second coat crosswise. Repeat at least 2-3 coats, each no more than 1 mm thick, to avoid unnecessary waste.

Curing: 8 hours after application, mist with water to cure. Conduct the water ponding test after at least 24 hours (delay if cold or poorly ventilated).

Special Notes:

Store out of reach of children. Do not swallow

Avoid eye contact. If splashed, rinse with clean water immediately; seek medical attention if discomfort persists

Tool cleaning: hardened paste is difficult to remove — wash tools with water immediately after use

Do not apply below 5°C, on wet surfaces or in rain. Use mixed paste within 2 hours; never re-mix with water after timeout

In humid or poorly ventilated areas, use ventilation equipment to speed curing. If tiles will be applied, use water-based tile adhesive to reduce hollowing or detachment.

Packaging / Storage

Store at 5-35°C in a cool, ventilated place; unopened shelf life: 12 months
