GENIOSIL^® IOTE

Applications
• Concrete Protection
• Construction Materials
• Fiber Cement Boards
• Hydrophobic Impregnation
• Infrastructure

The work performed (preparing the concrete surface, setting up a reference surface, application and quality control) must
follow the applicable regulations (in Germany these are the DAfStb repair work guidelines and the ZTV-ING).
- Concrete should not be impregnated until at least four weeks after it has been produced so that the setting of the cement
is not affected.
- New surfaces that are still unsoiled must be cleansed of coarse particles and dust deposits by sweeping or, if necessary,
using compressed air. Surfaces already weathered, and those heavily soiled by oil, rubber residue, etc., must first be
cleaned using superheated steam or high-pressure water before commencing treatment. It is imperative that the water
used be siphoned off immediately to prevent saturation of the concrete.
- Impregnation should always be performed on superficially dry concrete, i.e., when the surface of the concrete appears
evenly dry, no more damp patches are visible, and the moisture content equilibrium is established. To this end, moisture in
the surface zone of the concrete is measured using a suitable technique (CM method or other methods allowed under ZTV-
ING). The surface-zone moisture content of the concrete (from the surface to a depth of 20 mm) should not exceed 4 wt.%.
- Evenly apply the impregnating agent to the building material in several coats, wet-on-wet. Do not allow puddles to form.
The impregnating agent is applied by flow coating at reduced pressure. A lambskin roller may be used afterward for more
even coverage.
- In the event of unexpected rain, cover surfaces already impregnated and halt all further impregnation.
- GENIOSIL^® IOTE should never come in direct contact with bitumen. The resistance of insulating materials to GENIOSIL^® IOTE must be tested on a case-by-case basis for the required temperatures.
GENIOSIL^® IOTE is recommended for the hydrophobic impregnation and priming of concrete and reinforced concrete in
road, bridge and building construction. In addition it is suitable for the hydrophobic treatment of fillers and pigments.
