■ Product Introduction

Synthetic polymer waterproof coating: This type of waterproof coating is a single‑component or multi‑component coating made from synthetic rubber or synthetic resin as the film‑forming substance, and it has gradually become the mainstream product among waterproof coatings. It is used as one layer of waterproofing for Grade I and II roof waterproofing systems, or alone for Grade III roof waterproofing. In underground waterproofing works, it is used as one layer of waterproofing for Grade 1 and 2 systems, or alone for Grade 3 systems.

■ Product Characteristics

Excellent aging resistance
The product remains stable under UV, light, heat and oxygen, with a service life of over 20 years.

Strong adhesion
It has excellent repair and bonding performance to concrete substrates, glass, ceramics, plastic, metal, asbestos tiles, roofing tiles, and existing waterproofing membrane surfaces. Under external forces, it does not peel or delaminate, forming a stable, integral waterproof layer.

Good permeability
Thanks to its good permeability, when applied it can penetrate into the pores of cement‑based materials, blocking water passages, resulting in reliable waterproofing.

High elongation
The elongation at break is ≥600%, providing excellent crack resistance and effectively covering fine cracks in the substrate. Even if the substrate develops micro‑cracks due to external factors, the coating will not rupture or leak.

High and low temperature resistance
It withstands up to 170°C without flowing, and remains flexible without cracking at -20°C.

Available in bright colours
Colours can be adjusted according to design requirements or user needs, providing thermal insulation, decoration and aesthetic enhancement. Thus, it is a decorative and multifunctional waterproof coating.

Easy application
On any regular or irregular substrate, brushing or trowelling produces a continuous waterproof layer. It can be applied on damp substrates without blistering, with good film formation and fast curing, effectively shortening the construction period.

■ Wide Range of Applications

The product can be widely used on building roofs, basements, underground garages, indoor kitchens and bathrooms, water dispenser rooms, balconies, external walls, panel joints, window frames, window sills, column edges, pipe trenches and pipes, as well as grain silos, water towers, swimming pools, tunnels, steel‑structure factory roofs, and the inner walls of power plant cooling towers. It is suitable for construction in all climatic regions of China.

■ Application Method

1. The substrate shall be flat, free from loose sand, bumps, and cracks.

2. Before application, stir the product evenly.

3. The product can be applied by roller, trowel, or brush.

4. Apply in a clockwise direction, first horizontal then vertical.

5. Reinforce special areas with non‑woven or fiberglass fabric if necessary.

6. For general waterproofing, two coats are sufficient to achieve the required effect.

■ Application Requirements

1. Substrate preparation: The waterproof substrate must be firm, flat, clean, free from standing water, cracks, and unevenness. Cracks shall be repaired with cement mortar or Ostai repair mortar.

2. Depending on the waterproofing project and application requirements, apply 2–4 coats, adding a reinforcing fabric if necessary.

3. If the product contains sediment, stir thoroughly before application.

4. Water immersion testing is generally carried out after the coating has fully cured.

■ Precautions

• Apply at temperatures above 0°C.

• Do not apply outdoors when rain or fog is expected within 24 hours.

• If rain occurs during outdoor application, allow the coating to dry and form a film thoroughly after the rain stops, then resume application.
