A-FILM is a water based aliphatic alcohol finishing compound designed for use on plastic (freshly poured and screeded) concrete, to reduce the evaporation of water during finishing operations.
Conditions under which an evaporation retarder like A FILM is required can vary greatly in ‘appearance’ with temperature of both the day, the concrete , humidity and wind speed all contributing.
To assist the operator in determining the necessity for A FILM use please refer to the attached chart.
If the calculated evaporation rate is above 0.75kg/m2/hour then A FILM should be applied.
A-FILM will not normally interfere with subsequent toppings, tiling, render, surface coatings etc often used in industry. -AFILM is not considered to be a hazardous product. A-FILM is NOT a curing compound. A-FILM is approved by Main Roads Qld for use on concrete castings.
Surface Cure is a range of water based curing compounds complying with AS3799 are also approved by Main Roads Qld.
Pre-dilute with clean water, at a rate 1part A-FILM +9 parts water. Apply using a low pressure backpack type spray, at a coverage of 5-7m2/L each time the surface is broken (i.e. screed, bull float, troweling).
