Download brochureTwo component cementitious waterproofing made from cementitious binder, selected aggregates, special additives and synthetic polymers in water dispersion.
Key Features
Adheres to substrate and gives waterproof layer for the base in presence of upto 1.5 bar of pressure
Applications
- Waterproofing of internal and external surfaces of masonry
- Waterproofing for reinforced concrete structures such as swimming pools and lifts
Cautions
- Do not use for internal condensation
- Do not use gypsum or plaster boards, painted surfaces, wood, or fiber cement.
- Do not mix with admixtures, cement, or aggregates
- Do not use on surfaces subject to deformation
Shelf Life
12 months from date of production if stored properly in original, unopened, and undamaged sealed packaging.
Abrasion Resistance
| 7 days | 55 L/mil |
| 73 °F (23 °C) & 50 % R.H. |
Tensile Adhesion Strength
| 7 days | concrete substrate failure |
Diffusion Resistance to Water Vapor
7 days at 73 °F (23 °C) and 50 % R.H.
| 1 coat | 27 grains/hr/ft2 |
| 2 coats | 24 grains/hr/ft2 |
Layer Thickness
| Min. | Max. |
| 8 mils (0.2 mm) | 16 mils (0.4 mm) |
* Thicker application can result in cracking.
Ambient Air Temperature
> 45 °F (7 °C)
Substrate Temperature
> 45 °F (7 °C)
Pot Life
4 hours
As the temperature will affect the pot life, application temperature:
- Above 73 °F (23 °C) will reduce the pot life and workability
- Below 73 °F (23 °C) will extend the pot life and workability
Final Set Time
30 minutes tack-free time
Waiting / Recoat Times
2 hours minimum between coats
Coverage
| 1st coat | 100–150 ft/gal |
| 2nd coat | 150–200 ft/gal |
* (Coverage figures do not include allowance for surface profile and porosity or
material waste)
Mixing
- All mixing must be done mechanically using a low-speed drill (400–600 rpm) and Sika paddle.
- Place approximately 1/2 Component ‘A’ into a clean mixing container.
- While mixing, slowly add all of Component ‘B’ and continue to mix until you achieve a uniform paste with no lumps.
- Be sure to scrape down sides of the mixing container currently.
- Add remainder of Component ‘A’ and continue to mix until uniformly blended.
Curing Treatment
- As per ACI recommendations for Portland cement concrete, curing is required.
- Moist cure with wet burlap and polyethylene, a fine mist of water.
- Curing compounds adversely affect the adhesion of following lifts of mortar, leveling mortar, or protective coatings
- Moist curing should commence immediately after finishing. Protect newly applied Aqua-shield EC from direct sunlight, wind, rain and freezing.
- Store dry at 40–95 °F (4–35 °C)
- Component ‘A’ must be protected from freezing. If frozen, discard.
- Component ‘B’ must be protected from moisture. If damp, discard.
- Condition material to 60–75 °F before using.
- The product should only be applied over properly prepared surfaces with high-quality brushes, rollers, or “hopper-type’’ spray equipment.
- Surface should be SSD prior to application
- Two coats are recommended for maximum performance
- Apply thoroughly mixed coating generously with a loaded brush or roller.
- Always finish off with light strokes blending back into a coated area for uniform appearance.
- For application in direct sun or on a hot substrate, pre-wet surface and allow surface water to dissipate before coating.
- Refer to detailed guidelines when there is a need to place this product in cold & hot temperatures.
