Usage
Tough hard, easily applied high-build system. Corrosion protection for hydraulic steel structures (flood gates, steel sheet piles etc.), where a mechanically resistant coating is required. Also suitable as a fast curing single layer system of low solvent content for the corrosion protection of steel constructions (workshop application).Advantages

Packaging
| Sika Poxicolor® SW Neu | 15 kg net. |
| Sika® Thinner S | 25 l, 10 l and 3 l |
| SikaCor® Cleaner | 160 l and 25 l |
Colour
Black, redbrown, approx. RAL 7032, approx. RAL 9002.
In case of exposure to weathering Sika Poxicolor® SW Neu tends to chalking and yellowing. In case of higher demands to colour retention, SikaCor® EG-4 or SikaCor® EG-5 respectively are recommended as top coats.
Slight colour deviations are possible due to raw material characteristics.

SURFACE PREPARATION
Steel:
Blast cleaning to Sa 2 ½ according to ISO 12944-4.
Free from dirt, oil and grease.
Average roughness depth RZ ≥ 50 µm.
MIXING
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.
APPLICATION
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.
