KingKure 90A is mainly used for newly cast concrete and cementitious surfaces that contain GGBFS, PFA, micro-silica, dry shake hardeners or limestone to retain sufficient moisture to ensure full hydration of the cement.
Typical application areas include:
- High rise construction to eliminate water curing.
- Runways and roads.
- Roof decks.
- Retaining walls.
- Irrigation canals.
KingKure 90A should be spray applied as soon as possible to the fresh concrete, provided that the surface water has evaporated. Do not apply if bleed water is forming, or is present on the concrete surface. Stir KingKure 90A well before use to ensure even pigment dispersion.
KingKure 90A should be spray applied, the spray nozzle should be held approximately 450mm from the concrete surface and passed back and forth to ensure complete coverage. Pump pressure should be maintained to give an even, fine spray.
The applied film should be protected from rain for at least 3 hours; care should be taken to ensure that the film is not broken.
In case of formed concrete, KingKure 90A should be applied immediately after de-shuttering. In such a case the concrete surface must be dampened with clean water prior application of KingKure 90A.
KingKure 90A is available in 25 litre pails and 200 litre drums.
