MasterKure 250 (With fugitive dye) is a water-dispersed hydrocarbon resin-based curing compound for newly placed concrete. It forms a flexible film which prevents concrete drying out during the critical early stages of hydration thus ensuring satisfactory curing of the concrete.
MasterKure 250 is a water dispersed hydrocarbon resin based curing compound for newly placed concrete. It forms a flexible film which prevents concrete drying out during the critical early stages of hydration thus ensuring satisfactory curing of the concrete.
MasterKure 250 meets the water retention requirements of AS3799-1998 when applied at the recommended application rate. It has been formulated from special aliphatic resins and being water dispersed is of low toxicity.
Subsequent renders, toppings or coatings can be applied once sufficient time has elapsed to achieve full degradation of the MasterKure 250. Alternatively, if insufficient time has elapsed to achieve full degradation, renders, toppings or coatings can be applied once the MasterKure 250 has been mechanically removed.
AS3799-1998 specification requires curing compounds to achieve an Efficiency Index of not less than 90% in 72 hours. Water retention tests conducted on MasterKure 250 provided the following results.
| Application Rate Index | Efficiency Index (1) |
|---|---|
| 5m²/litre | 90% |
| VOC content: 87g/L Test method: SCAQMD 304-91 | |
Water retention expressed as the percent of a control panel with no MasterKure 250 applied.
Drying Time: Approximately 1-3 hours at 23°C.

MasterKure 250 should be applied immediately after the final finishing operation as soon as the surface has hardened sufficiently to prevent marring. The surface should be damp but with no free water on it. Do not wait until the next day to apply the MasterKure 250 Delaying the application until the next day will allow considerable loss of moisture, reducing the effectiveness of the curing membrane.
Apply uniformly and thinly so as to form a continuous film. MasterKure 250 is applied using a wide, short nap roller, brush or low-pressure spray. Do not thin, avoid forming puddles.
MasterKure 250 can contain a fugitive dye, which aids the contractor to obtain a uniform coverage and avoids wasteful double applications.
Actual coverage depends on the texture and porosity of the surface. The recommended application rate is 5m²/litre.
MasterKure 250 is available in 20L cubes or 200L drums with or without a fugitive dye and 1,000L pallecon.
MasterKure 250 has a shelf life of 12 months. Store out of direct sunlight, clear of the ground on pallets protected from rainfall
