- Uses
Aquacoat is ideal for:
- Protecting concrete, brick, block, stone and other masonry above or below grade.
- Interior and exterior in applications such as tanks, tunnels, pools, manholes, reservoirs, pipes, troughs, walls, etc.
- Application
Surface Preparation:
All surfaces in contact with Aquacoat shall be free of dirt, oil, grease, laitance and other contaminants that may act as bondbreakers. All unsound concrete should be removed to ensure a good bond. Smooth, dense surfaces may need to be mechanically abraded to provide necessary bonding requirements. Mechanically prepare the substrate to a minimum CSP 2 following ICRI Guideline 310.2R to allow proper bonding. Moisten area prior to application. Always apply a test patch. Maintain contact areas between 40°F (4°C) and 90°F (32°C) prior to repair and during initial curing period.
Application Thickness:
Feathedge - 1/16”
Yield:
50 lbs (22.7 kg) will fill approximately 0.43 ft³ (0.012 m³) when 6.0 quarts mixing water is used.
Coverage:
One 50 lb (22.7 kg) bag should cover approximately 300–400 ft² for damproofing (1 coat). For waterproofing (2 coats), Aquacoat should be applied at 200–250 ft² on the first coat and 300–400 ft² on the second coat. Total minimum thickness for proper waterproofing is 1/16”. Coverage may vary depending on the porosity of surface.
Mixing:
For best results, use a mechanical mixer with rotating blades or use a heavy duty 1/2” (15 mm) (or larger) low-speed, corded drill and mixing paddle #6 per ICRI Technical Guideline 320.5R. Pre-wet mixer and empty excess water. Place 6.0 quarts of cool, clean potable water per 50 lb (22.7 kg) bag in mixer, then add dry material. Mix on low RPM for a total of 3 to 5 minutes until a homogeneous mixture is achieved. Mix only enough material that can be placed within working time. Do not blend excess water as this will cause bleeding and segregation. Do not use any other admixtures or additives.
Placing:
Place material consistently, without multiple layers. Avoid any air entrapment. For areas greater than 1/16” in depth, apply US SPEC Quickset 20 to within 1/16” of final repair. Install in one consistent application for best color match. Material performs best when applied at cool periods in the day.
Finishing & Curing:
Follow standard ACI curing practices. Exposed surfaces should be cured with a membrane forming curing compound such as US SPEC Maxcure Resin Clear, US SPEC Hydrasheen or US SPEC Hydrasheen 30%.

Regulatory & Compliance
- Limitations
In addition to limitations already mentioned, please note the following. Do not apply when the surface or ambient temperature is below 40°F (4°C) or expected to fall below 40°F (4°C) within 48 hours. Do not apply over surfaces that are frozen or contain frost. Do not apply over any active faults or cracks in the substrate without addressing any movement that may occur. Allow concrete to fully cure for 28 days before the use of this product. This material is not intended for use as a horizontal wearing surface. Setting time will speed up in hot weather and slow in cold weather. For hot and cold weather applications, contact your US SPEC manufacturer’s representative.
