Description
Finduro Aliphilm AA is a low viscosity aliphatic alcohol blend in an aqueous solution which reduces rapid water evaporation during the critical ‘finishing’ period of the concrete, particularly under adverse weather conditions such as high temperature, high wind and low humidity.
Applied to freshly laid surfaces, Aliphilm AA works to retain the moisture in the concrete which leads to improved workability and finishing of surfaces and reduces the risk of shrinkage cracking.
Aliphilm AA is a clear formulation of VULK’s existing Aardcure AA and is specifically formulated to be suitable for light coloured and colour through decorative concrete mixes and improves results on exposed aggregate or trowel-finished projects.
Application Instructions
Material Preparation
Thoroughly shake the undiluted Aliphilm AA prior to dilution. Add water to the Aliphilm AA at a recommended dilution rate is 1 part Aliphilm AA to 9 parts water but higher concentrations can also be effective, up to 1:4 in extreme conditions and up to 1:3 when applied after Expose XA for next day washing of exposed aggregate.
Application Method
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. Diluted Aliphilm AA is applied after surface screeding but before surface finishing processes. Application is recommended via low pressure spray unit. Spray at a rate of 1L/5m2 to achieve consistent coverage in even coats.
As a rapid moisture evaporation retarder
After application, finishing of the concrete can continue. The film formed by Aliphilm AA will reform during this process, depending on the amount of surface bleed water present. Continue trowel finishing after the AA film has begun to evaporate.
As a curing aid for next day washed aggregate finishes:
After trowel finishing is complete apply EXPOSE XA surface retarder to full saturation. Allow the EXPOSE XA to penetrate the surface.
Once the penetration is complete spray apply the diluted ALIPHILM AA to the surface at 1L/5m, which will further slow the hardening of the upper layer of the concrete and enable faster surface washing times the next day.
As a curing aid for washed aggregate or trowel finished surfaces
Spray apply diluted Aliphilm AA at a rate of 1L/5m2 as soon as the surface is trafficable by foot and will not be damaged by the application. Use for this purpose should be reserved for projects of critical aesthetic importance and will assist in short term moisture retention only. See further information regarding curing recommendations listed in this document.
Effective application temperatures are between 5ºC and 40ºC.
