All You Need To Know

frequently asked questions

An evaporation retardant is a product used in concrete construction to reduce rapid moisture loss during the curing process. It helps prevent plastic shrinkage and cracking without affecting the adhesion of curing compounds and other treatments.

Using an evaporation retardant is important because it helps maintain the moisture content in the concrete, allowing it to cure properly. This helps prevent issues such as surface cracking and ensures the concrete achieves its desired strength and durability.

An evaporation retardant should be used in situations where rapid moisture loss is a concern, such as in hot and dry weather conditions or on large concrete placements. It is especially beneficial for exterior concrete work.

The application method may vary depending on the product, but generally, an evaporation retardant is sprayed onto the surface of the freshly placed concrete. It forms a thin film that helps slow down the evaporation of moisture. Follow the manufacturer’s instructions for the specific product you are using.

Yes, most evaporation retardants are designed to be compatible with other concrete treatments, such as curing compounds and sealers. However, it’s always a good idea to check the product compatibility and follow the manufacturer’s recommendations.

Yes, it’s important to follow the safety guidelines provided by the manufacturer. Wear appropriate protective equipment, such as gloves and goggles, during application. Avoid direct contact with skin and eyes, and ensure proper ventilation when working with the product.

An evaporation retardant primarily works to maintain the moisture content in concrete during the initial stages of curing. While it doesn’t directly alter the overall curing time, it helps ensure that the concrete cures evenly and develops its full strength by preventing premature moisture loss.

While evaporation retardants are typically used in hot and dry conditions to prevent rapid moisture loss, they can also be beneficial in cold weather. They help in maintaining the moisture necessary for proper curing, which can be challenging in cold, dry conditions.

Yes, each evaporation retardant product has a recommended coverage rate, which is usually specified in the product documentation. It’s important to apply the product at this rate to ensure optimal performance. Over or under-application can affect the effectiveness of the product.

Evaporation retardants are designed to be temporary and do not permanently alter the appearance of the concrete surface. They form a thin, transparent film that dissipates after fulfilling its role in moisture retention during the initial curing period.
