Weifang Shihua Chemical Building Material Co., Ltd.
| Supply Ability | 1000000kg per Month |
| Mixing Ratio | Weigh A & B strictly by weight ratio; wrong ratio causes uncured sticky or brittle film |
| Substrate Requirement | Dry solid substrate preferred; interface treatment required for damp surface |
| Application Method | Cold‑applied by troweling or brushing |
| Low‑temperature Flexibility | No cracking at ‑35 ℃ |
| Chemical Resistance | Resistant to water, acid, alkali and salt corrosion |
| Packaging Details | Metal Barrel |
| Stirring | Electrically stir 3-5min until uniform; poor mixing causes partial curing failure |
| Cured Film Appearance | rubber‑like elastic film after curing |
| Waterproofness | No water penetration at 0.3 MPa for 120 min |
| Brand Name | shhous |
| Model Number | two‑component |

Two‑Component Polyurethane Waterproof Coating Construction Technology
Apply extra reinforcement layer for weak waterproof positions: internal‑external corners, pipe roots, floor drains, construction joints and deformation joints. Apply 1‑2 thin coats of mixed coating. Extra‑layer width ≥250mm on each side. Start main‑area construction after reinforcement layer dries.
Weigh component A and component B strictly according to weight ratio and pour into mixing bucket. Electrically stir for 3‑5 minutes until uniform color without lumps or particles.
Important: Mixed material has limited pot‑life. Discard gelled mixture. Do not dilute with water.
Mainly trowel‑applied, assisted by brushing. Apply thin coats repeatedly; heavy single‑coat is prohibited. Apply first thin coat. Next coat can only be started after previous coat is dry. Brush in cross directions to reach designed film thickness.
Natural curing for each coat. Ensure full curing after whole application. Protect film from rain, ponding, treading and mechanical damage during curing.
Apply cement‑mortar protective layer after full curing and inspection acceptance.
Notice: Polyurethane film is not UV‑resistant. Direct exposure is not allowed. Protective covering is required for exposed areas.
Key Construction Points
| No. | Item | Precautions |
| 1 | Substrate | Substrate must be solid & dry, free of standing water, dust and oil; interface treatment required for damp surface |
| 2 | Mixing Ratio | Weigh A & B strictly by weight ratio; wrong ratio causes uncured sticky or brittle film |
| 3 | Stirring | Electrically stir 3-5min until uniform; poor mixing causes partial curing failure |
| 4 | Pot-life | Use up within pot-life after mixing; discard gelled material, do not dilute with water |
| 5 | Coating Layers | Apply thin multi-coats in cross directions; avoid heavy coat to prevent blistering & sagging |
| 6 | Temperature/Humidity | Construct at 5℃-35℃; low temp slows curing; avoid rainy and dewy days |
| 7 | Ventilation | Keep ventilated, avoid inhaling volatile gas, wear protective equipment |
| 8 | Details | Apply extra reinforcement layer on corners, pipe roots and floor drains first |
| 9 | No Direct Exposure | Film is not UV-resistant; mortar protective layer mandatory for exposed areas |
| 10 | Tool Cleaning | Clean tools with special cleaner before curing; hard to clean after curing |
| 11 | Curing Protection | Avoid rain, ponding, treading and sharp-object damage during curing |
| 12 | Moisture Content | Standing water reduces adhesion and causes blistering; moisture content must meet requirement |
