JS Polymer-Cement Waterproofing Coating — KS-901E
Two-component polymer-cement (JS) coating: liquid polymer emulsion + cement-based powder. Bonds to damp substrates, cures to a flexible-yet-rigid composite film, and tiles over directly — the highest value-per-dollar waterproofing for wet rooms and basements. Keshun KS-901E and E-11 JS series.
Keshun KS-901E / E-11 Series — produced by Keshun Waterproof Technologies (SZSE: 300737)
Typical Specifications
| Item | Typical Value |
|---|---|
| Mix ratio | Liquid : powder per datasheet (typically 1:0.8–1:2 by weight by type) |
| Coats | 2–3 coats, cross-applied; total dry-film typ. 1.2–2.0 mm |
| Substrate | Concrete / mortar — damp (no standing water) acceptable |
