PC-Buildcure® AC

Ready to use, liquid membrane-forming compound based on acrylic emulsions in waterfor curing concret

PACKAGING

PC-Buildcure® AC 20 Litter piles and 200 Litter drum.

PC-Buildcure® AC roper curing is crucial for the durability and strength of concrete. Traditional curing methods are time-consuming and start after initial water evaporation. PC-Buildcure® AC, an acrylic emulsion-based membrane-forming curing compound, is a solution that creates a seamless film on fresh concrete and mortars, preventing capillary water evaporation, avoiding cracks, and promoting efficient hydration. It is applied once during the critical hardening period and complies with ASTM C 309.

ADVANTAGES

Provides protection against acute sun rays and UV rays, preventing quick drying of freshly placed concrete.
Especially useful in cases where early plastering is required.
Ensures optimum hydration, leading to stronger end hydration products.
Allows for better quality control at job sites.
Does not alter the normal setting of cement.
Minimizes shrinkage cracks during early stages of curing.
Single application, saving on labor costs.
Easy to apply, ideal for overhead curing and hard-to-reach areas (such as chimneys).
Suitable for areas with water shortage, eliminating the need for water spraying, hessian, PE films, and other alternatives.
Increases solar reflectance, reducing the temperature of the concrete.
Fixes micro-cracks in the concrete, with no need for removal before treatment.

USES

PC-Buildcure® AC is a versatile solution that finds utility in numerous applications. It’s particularly useful in large areas of concrete that are directly exposed to harsh environmental conditions like sunlight and heavy winds. Additionally, it’s an ideal choice for early plastering, concrete bridges, canal linings, airport structures, motorways, harbors, port piers, dams, irrigation structures, roof decks, retaining walls, overhead patch repairs, and inaccessible areas, as well as tall structures
like chimneys and cooling towers

APPLICATION

For optimal results, apply PC-Buildcure® AC immediately after the disappearance of water sheen from the surface. Ideally, this should be done within 30 minutes, depending on the temperature. Avoid applying PC-Buildcure® AC when standing water is present. We recommend fogging the surface before application. To cure concrete retained on form works, thoroughly wet the
concrete after opening the shuttering, then spray or brush PCBuildcure® AC. You can use a regular knapsack sprayer (like an
insecticide tree sprayer) with a suitable nozzle for application. For larger areas, motorized continuous spraying devices are
recommended. Hold the nozzle about 0.7 to 1.0 meters from the surface and ensure complete area coverage. To achieve a fine spray, maintain the pump pressure throughout the operation. Quality control is easy because the product is whitish in color, and areas that were missed can be sprayed again. If used correctly, certain subsequent coats can be applied without adhesive problems. Additional substrate preparation is not necessary. Standard coating systems and plasters can be applied without removing PC-Buildcure® AC. However, reactive resin systems, such as epoxy or polyurethane resins, may not always be compatible with PC-Buildcure® AC. Specific trials should be carried out before applying such systems.

LIMITATIONS

There are two key considerations to keep in mind when utilizing PC-Buildcure® AC in concrete trains or similar applications. Firstly, it’s essential to avoid continuously recirculating the solution in high-shear pumps since this can cause the emulsion to break down before spraying. If recirculation is necessary, it’s recommended to use a low-shear diaphragm pump for optimal results. Secondly, please note that the minimum application temperature should be 5°C to ensure proper functionality.

EQUIPMENT

To apply PC-Buildcure® AC, one may use spray equipment
such as a knapsack or motorized sprayers that produce a fine mist, without causing damage to the emulsion. However, it’s recommended to conduct an application trial to determine the suitability of the equipment.

STORAGE

PC-Buildcure® AC offers a minimum shelf life of 12 months, providing it’s stored within a temperature range of 4°C to 35°C. It’s important to avoid freezing and extended exposure to heat or direct sunlight. In the event the product’s temperature falls beyond the specified range, kindly contact the PC-WC Technical Service Department for appropriate guidance. To prevent moisture loss by evaporation, keep the containers tightly sealed and airtight.

HEALTH AND SAFETY

PC-Buildcure® AC does not fall under the hazardous category according to the current regulations (refer to notes 1 and 2
below). However, it is critical to avoid swallowing or direct contact with skin and eyes, whether in bulk or spray form. Wearing protective gloves and goggles is highly recommended. In the event of skin contact, wash with water immediately. In case of eye contact, rinse thoroughly with water and seek medical attention. If ingested, do not induce vomiting and seek medical attention immediately. For additional information, please consult the Material Safety Data Sheet available for this product.
