Solvent-free (GISCODE RE30 according to TRGS 610), water-free and very low-emission (EMICODE EC1^Plus according to GEV), low-viscosity two-component epoxy resin primer for the pre-treatment of absorbent and non-absorbent substrates prior to levelling and installation works.

Okapox GF can be used as a moisture mitigation system¹⁾ to block residual moisture in cementitious substrates prior to the installation of resilient and textile floor coverings as well as parquet and engineered wood flooring.

Okapox GF protects moisture-sensitive substrates, such as calcium sulphate screeds, against moisture penetration from above and can also be used as a binder for the production of epoxy resin mortars.

At a layer thickness of 0.5 mm (consumption approx. 500 g/m²), Okapox GF provides a water vapour diffusion resistance (sd value) of 200 m and can therefore be used as a moisture mitigation system¹⁾.

Okapox GF can also be used in combination with Kiesel glass fibre mesh to create reinforced and stabilised installation substrates.

In combination with Kiesel DEZ, Okapox GF is also suitable as a binder for the production of drainage screeds.

Note: “Patented for staircase construction by Schweizer, 73342 Bad Ditzenbach, Germany, Patent No. DE 10 2012 105 665.”

The substrate must be inspected and ready for installation in accordance with the respective regulations of the individual countries as well as the current state of technology. Substrates must be pre-treated in accordance with the current BEB datasheet ('Evaluation and Preparation of Substrates').

Depending on the type of substrate, floor coverings and the requirements such as subsequent loading conditions, prepare substrate for laying using suitable Kiesel primers/pre-coats and self-levelling compounds. With non-absorptive substrates, apply a Kiesel levelling or patching compound to a minimum thickness of 2 mm. Technical datasheets of other Kiesel products used, must also be complied with. A system structure must be ensured.

Using a screwdriver to pierce the bottom of the lid container several times. Let the hardening liquid completely flow into the lower unit. When completelly empty remove upper unit and mix the two components intensively with an electric stirrer until the mixture is free of streaks. Then decant into another container and mix it again.

As a primer before levelling and installation work or in Okamul PU-FCA waterproofing system: Over absorbent substrates apply a second coat of pure Okapox GF (consumption approx. 300 g/m²) immediately after penetration of the first coat. Subsequently transfer over the second coat quartz sand in excess; grain size 0.6 - 1.2 mm (Okamul PU-FCA grain 0.2 - 0.7 mm).

As a moisture barrier: Okapox GF creates a barrier for residual moisture max. 7.0 CM-% in concrete substrates and 5.0 CM-% for cement screeds under textile and resilient floor coverings and suitable engineered wood.

As a primer to protect moisture sensitive substrates: E.g. for calcium sulphate screeds apply one coat of Okapox GF and after initial drying time of 48 hours apply an additional prime with Okatmos® UG 30 / Okatmos® EG 20. 

When used as an epoxy resin mortar: Mix Okapox GF to a homogeneous consistency and add up to 7 kg of quartz sand (grain size 0.6-1.2 mm) per kg Okapox GF. Optionally raise the stability of the mix by adding Okapox additive stabiliser (about 1-4%).
To accelerate the reaction time and thus to shorten the waiting time use one unit of Okapox accelerator (300 g) per 3.5 kg Okapox GF. The reaction time may be reduced to about 3.5-4 hours.

When used as a drainage mortar / drainage screed on balconies and terraces: To prepare drainable and efflorescence-free screeds, add 1 kg of Okapox GF to a large mixing bucket and mix to homogenous consistency with 25 kg of drainage screed additive Kiesel DEZ with an electric mixer at approx. 600 RPM until all aggregates are wetted with epoxy resin (visually recognisable by a deepening of the colour of the aggregate). For larger amounts use correspondingly suitable mixer and mixing bucket. Mixing ratio of 1:25.

The finished mixture is applied on previously prepared surface consisting of appropriate drainage mats, waterproofing grout Servoflex DMS 1K Plus SuperTec or Servoflex DMS 1K-schnellSuperTec (only up to a drainage distance of ≤ 2 m). The minimum layer thickness is 25 mm (on drainage mats ≥ 35 mm).Use insulation strips around perimeter adjoining wall structure. The substrate must have a surface sloped at least 1.5%.
The drainage pour sizes shall be arranged in a square pattern without exceeding maximum length of 4 meters. The newly installed drainage system must be protected from rain and sunlight during the reaction time (at least 6 hours *). The optimal processing temperature is approx. 12 ° C to max 25 ° C. After complete reaction time of the drainage screed use Servoflex Trio schnell SuperTec and install tiles providing back- buttering method. Care must be taken to ensure that the covering material is almost fully bedded and that the joint space between the tiles is kept as free as possible from installing materials, e.g. by mechanical scraping. The tiles to be installed shall not exceed a surface area of 10,000 cm² and shall not exceed 1.20 m edge length and be suitable for the intended purpose. Bright tiles are preferable. Dark and large format flooring materials require a reduction in the above mentioned sizes.

Consumption: Approximately 16 kg / m² per m² / cm thickness drainage mortar, depending on compression.
