Theoretical material-consumption/ coverage without loss for medium dry film thickness of:

Concrete:

The surfaces to be coated must conform to the building standards and must be capable of bearing loads, firm and free from bond-impairing materials. The average tensile strength of the surface according to DIN 1048 should be at least 1.5 N/mm² and must not fall below the lowest individual value of 1.0 N/mm². In the case of high mechanical loads, the average nominal value is 2.0 N/mm² and the lowest individual value 1.5 N/mm². Suitable preliminary coatings compatible with the system are to be used. Cavities, shrinking holes or surface roughness have to be levelled e.g. by Icoment-520 Mortar. The respective rework times must be adhered to.

Steel:

Blast-cleaning to Sa 2 ½ according to ISO 12944-4.

Free from dirt, oil and grease.

Stir component A very thoroughly using an electric mixer (start slowly, then increase up to approx. 300 rpm). Add component B carefully and mix both components very thoroughly (including sides and bottom of the container). Mix for at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into clean container and mix again shortly as described above. During mixing and handling of the materials always wear protective goggles, suitable gloves and other protective clothings.

The method of application has a major effect on achieving uniform thickness and appearance. Spray application will give the best results. The indicated dry film thickness is easily achieved by airless spray. Adding solvents reduces the sag resistance and the dry film thickness. In case of application by roller or brush, additional applications may become necessary to achieve the required coating thickness, depending on type of construction, site conditions, colour shade etc. Prior to major coating operations a test application on site may be useful to ensure the selected application method will provide the requested results.

By brush or roller
Airless-spraying / Airmix-spraying:

• Nozzle size ≥ 0.33 mm (≥ 0.013 inch)

Conventional high pressure spraying:

• Nozzle size ≥ 1.3 mm
