Prime Evaploc is a water soluble liquid when sprayed on curing concrete creates a plastic film that retards water evaporation in setting concrete. This greatly reduces the chances of plastic shrinking (known as hairlines) while making the concrete more workable for an extended period.


  • Prime Evaploc reduces the chances of plastic shrinkage by up to 80% if the ground surface has been thoroughly watered prior to concrete placement.
  • Using Prime Evaploc will allow the concrete to be workable for a longer period by delaying the surface to crust over in windy and hot conditions.
  • Once applied the concrete surface will have a creamy feel under the trowel making finishing easier without altering the concrete strength or durability.
  • Prime Evaploc retards concrete water evaporation by up to 80% in windy conditions and up to 60% in sunlight.
  • The distinctive fluro green colour ensures easy and even product application. The bright colour that makes application so easy leaves no staining or residue once cured.


Prime Evaploc is a cost-effective, concentrated product which costs approximately 10 cents per square metre.

Direction of Use

Mix 1 litre of Prime Evaploc concentrate with 9 litres of water. 10 litres of diluted Prime Evaploc will cover approximately 50 square meters of concrete with one coat. For easy application use a Prime Backpack Spray Unit or any garden sprayers. Apply the first coat of diluted

Prime Evaploc once you have screeded and bull floated the concrete. A second coat is then applied after finishing the concrete. This coat is to be applied once the surface has cured enough that the product will not pit the concrete.
