Product Made in Japan
Manufacturer: Okabe
Model: G-0420
Surface preparation agent for concrete joint
◆Performance
| Specific Gravity | Condition | pH | Viscosity (20℃) | Etching Depth | Usage Instructions | Sprayed surface | Standard Coating Amount |
|---|---|---|---|---|---|---|---|
| 1.07 | Light brown liquid | 7.5 ± 0.5 | 100Pa.s | 3~5mm | Spray with a watering can or sprayer. | Concrete surface | 300g/㎡ |
How to use
● Exposes aggregates on the surface by uniform osmotic force, resulting in enhanced adhesion and waterproof performance of the joints.
● Does not deteriorate the concrete strength. Forms economical and highly water-tight joints compared to the conventional green cut method.
● No harmful substances are used as main ingredients.
Cautions
● To wash away Disparlight CR, use a high pressure washer (approximately 30kg/cm2).
● Provide protection with cover plate, etc., before spraying in order to prevent Disparlight CR from flowing in directly between the formwork and concrete.(If Disparlight CR flows in, etching may occur on the
concrete surface after the formwork is removed.)
● Spray Disparlight CR uniformly with sufficient care. (Insufficient or uneven spray causes uneven etching.)
● Disparlight CR is stable until -5°C but store it in such a way as to avoid freezing.
◆Performance

| 1.1 | Light brown viscous liquid | 8.0 | 14000 ± 1000Pa.s | 3~5mm | Apply with a brush or roller brush. | Formwork surface | 350g~450g/㎡ |
How to use
1. Apply Disparlight DV to formwork before placing concrete
2. Curing of concrete
3. Remove formwork within a certain time
4. Wash concrete surfac
Cautions
● The retardation effects of Disparlight DV are affected by temperature. Therefore, pay sufficient attention when washing the concrete after removing formwork.
● Provide protection such as covering with a sheet in order to prevent outflow due to rain etc.
● Twice application of Disparlight DV is recommended to prevent uneven exposure of aggregates by washing. The amount of each coat should be approximately 1/2 of the standard application amount of Disparlight DV.
● After application of Disparlight DV, the coat dries up but when it comes into contact with fresh concrete, it becomes wet and effective again
