[MECHANISM]

How the membrane cures

Moisture-triggered cross-linking means the base has to be damp — that one condition decides whether the bay can be coated today.

First coat curing to a satin finish across a prepared slab
First coat, two hours in
  1. 01

    Wet the base

    Substrate damp, not flooded — the reaction needs moisture, not a puddle.

  2. 02

    Mix A into B

    4 : 1 by weight, two minutes at 400 rpm; the clock starts now.

  3. 03

    Roll within the pot life

    Cross-wise second coat inside 40 minutes, before the skin forms.

[APPLICATION]

Application step by step

  1. Prepare the substrateShot-blast or grind; fill blowholes; dampen but do not flood.
  2. Hold the pot lifeMixed at 400 rpm for two minutes, then used inside 40.
  3. Two coats, cross-wiseSecond pass at right angles once the first is touch-dry.
[SITE LIMITS]

Site conditions and limits

  • Substrate moisture≤ 8%Above that the membrane blisters on cure.
  • Ambient temperature5–35 °CBelow 5 °C switch to VH-AD15; above 35 °C shade the slab.
  • Dew point margin≥ 3 °CMeasured on site, not read off a forecast.
Hand-held moisture and dew-point meter held against a concrete wall
