Testing

The NSF/ANSI 61 is a set of national standards that relates to water treatment and establishes stringent requirements for all equipment and products that come in contact with either potable (drinking) water or products that support the production of potable water.

Application

ACR Accelerating Agent should only be applied to a surface that has already received treatment from TechCrete Waterproofing Agent. ACR Accelerating Agent is required for any system warranties offered by Alchemco. Any additional application questions should directed to the Technical Department at 800-610-2895.

Do not apply where ambient temperatures are below +39°F (+4°C) or above +950F (+35°C).

Application Rates

Normal: 1 gallon per 200 square feet (1 liter to 5 square meters) on average. Can vary depending on substrate absorption, including the age of concrete and original density.

Application Method

1. On Day 1 – Apply TechCrete 2500 Waterproofing Agent in accordance with its directions and application rates. When the surface becomes touch dry – (usually 2-6 hours depending on wind conditions and ambient temperature) flood spray the treated areas with water. If the product is still wet at 6 hours, begin first watering.

2. On Day 2 – 24 hours after application of TechCrete 2500 Waterproofing Agent, apply ACR Crack & Void Treatment to all cracks that are less than 5/64” (2.0 mm), then apply ACR Accelerating Agent to the entire surface of the concrete.

3. On Day 3 – 24 hours later water again.

4. After the third watering, block drains and pond area for a minimum of 12 hours to verify the waterproof seal.
