Lifted from a recent tanking spec from Sovereign:
Prior to commencing operatives should be informed of the purpose of tanking so they understand the integrity of the system cannot be compromised.
For the chemical reaction to take place K11 must be applied to a damp surface where the underlying substrate has a high moisture content. Failure to do so will result in the future breakdown of the system. Dry areas should be prewetted with water, as early as possible, to assist this process.
1. Apply neat Antisulphate to the new rendercoat and allow to soak in.
2. Wet the areas to be treated with wash down water consisting of 9 parts water to 1 part SBR Bonding Agent 20 minutes before the application of K11. The 20 minutes is an approximate time that will ensure that the inner surface is still wet, but without surface water.
3. Mix Hey’di K11 Grey with SBR Bonding Agent diluted 2 parts Bonding Agent to 1 part water, until
a plastic consistency is obtained. Approximately 8 litres of gauging water will be required per 25 kg of K11. Apply the K11 slurry using a block brush at a rate of 2 kg/m² giving a K11 coating thickness of approximately 2 – 2.5mm per coat.
Note 1: It is critical to the overall success of the Hey’di K11 System that the correct amount of SBR is
incorporated into the mix design.
Note 2: Do not mix more K11 than 1 man can apply in 20 minutes.
Note 3: Keep the wash down (9 water to 1 part SBR Bonding Agent) well away from the K11 gauging.
