Vulk - Aardcure AA - Aliphatic finishing aid

Typical Properties

Curing Time

Aardcure AA will evaporate as concrete finishing occurs and evaporation is dependent upon environmental conditions.

Estimating Data

20L of undiluted Aardcure AA will cover yield up to 200L of mixed material. At a 1:9 mix ratio, theoretical coverage is 1000m².

Aardcure AA is a low viscosity aliphatic alcohol blend in an aqueous solution. Aardcure AA is applied to freshly placed concrete surfaces, to reduce rapid water evaporation during the critical finishing period of the concrete, particularly under adverse weather conditions such as high temperature, high winds and low humidity.

Application Instructions

Application Guidelines

Material Preparation

Thoroughly shake the undiluted Aardcure AA prior to dilution at desired rate.

Add water to the Aardcure AA at a reccomended dilution rate is 1 part Aardcure AA to 9 parts water but higher concentrations can also be effective.

Application Method

Diluted Aardcure AA is applied after surface screeding but before finishing the concrete. Agitate the material until thoroughly mixed.

Assess the application area so that a fixed volume of mixed material can be applied over a fixed area to determine the correct application rate.

Application is recommended via low pressure spray unit . Spray at a rate of 1L/5m2 to achieve consistent coverage in even coats.

After application, finishing of the concrete can continue. The film formed by Aardcure AA will reform during this process, depending on the amount of surface bleed water present.

Effective application temperatures are between 5ºC and 40ºC.
