FlexKrete Fill Tips & Tricks

  1. FLEXKRETE: You have to mix in the FlexKrete catalyst BEFORE adding sand/aggregate, failing to do this will result in the product not setting. The sand/aggregate MUST BE DRY AND FREE OF MOISTURE (use kiln-dried sand and NOT PLAY SAND), failing to follow this will result in the product not setting.
    Moisture in the repair area will have the same results as adding wet sand, so it may be advised to torch the repair area to drive away any moisture.
    FlexKrete may be sticky to trowel but misting your trowel with acetone will make troweling much easier.
