Frequently asked questions

View all FAQs
  • What is ACTFLEX 200 Water-Based Primer for?
    Compatibility

    200 Blue is an internal primer for porous substrates - concrete, masonry, fibre cement, and rendered surfaces - before Forspec internal waterproofing membranes. Improves substrate adhesion and stability.

  • Coverage and cure?
    Performance

    Coverage is 4-6 m² per litre. Tack-free in 1-2 hours at 25°C - you must apply the membrane within 24 hours or re-prime. Apply at 80-120 microns WFT. Ready-to-use, no mixing.

  • Why is it coloured blue?
    Installation

    The blue colour provides visual verification that the substrate has been fully primed. On porous substrates the colour may be subtle - check thoroughly with a torch from a low angle to confirm coverage.

  • Which membranes does it pair with?
    Compatibility

    200 Blue is the standard primer for ACTFLEX 906 WPU and other water-based internal wet area membranes. For solvent-based polyurethane membranes use 600 Primer or 700 PU Primer instead.

  • Properties of the cured film?
    Performance

    35-45% solids content with density approximately 1.05 g/cm³. The primer penetrates deeply into porous substrates and reduces dusting before membrane application.
