Description
MASTERKURE 106 is a solvent free, membrane forming wax emulsion, suitable for spray application to freshly poured concrete.
The resultant film retains sufficient moisture in the concrete to ensure full hydration of the cement; essential for optimum strength development. Membrane cured concrete is typically harder and exhibits a dust free surface with a reduced incidence of drying shrinkage cracks.
Primary uses
As a more effective and economical alternative to hessian and water and polythene curing regimes. Suitable for use on all concrete surfaces.
Advantages
- Eliminates the need for water.
- Single application.
- Promotes a harder dust free surface.
- Cured film is clear and water repellent.
- Reduces drying shrinkage.
- High curing efficiency.
- Reduced labour costs.
- Water based.
Packaging
MASTERKURE 106 is available in 210 litre drums.

Directions for use
The compound should be spray applied as evenly as possible on to the freshly placed concrete.
For horizontal surfaces MASTERKURE 106 should be applied as soon as the initial surface sheen has disappeared from the concrete surface. In the case of formed concrete, the MASTERKURE 106 should be applied immediately on removal of the formwork. To assist breakdown of the MASTERKURE 106 film on vertical and formed surfaces, it is essential to dampen down the concrete with clean water prior to application.
Coverage
The recommended rate of application is 5-6 square metres per litre. This corresponds to that at which MASTERKURE 106 has been tested, and at which it attains the claimed degree of curing efficiency. In favourable conditions such as shaded interior surfaces, adequate curing can be achieved with extended coverage rates.
Film breakdown
The time for deterioration of the membrane is dependent on a number of variables, which include film thickness, degree of exposure to weathering, traffice UV light, and the porosity of the substrate concrete.
Subsequent surface finishes
It is important that the complete removal of the MASTERKURE 106 should be ensured prior to the application of any surface finish or additional treatment. It is recommended that where the concrete is to receive a coating or the application of tiles, the use of MASTERKURE 181 is considered.
MASTERKURE 181 is a resin based non-degrading curing membrane meeting the requirements of ASTM C-309 Type 1 Class B. It is additionally formulated to act as a primer for many finishes or to seal concrete surfaces and provide a degree of abrasion to flatwork.
