Frequently asked questions

For optimal durability and the certified protective layer, at least 2 full coats are essential. The first coat acts as a bonding promoter on absorbent substrates, the second forms the final elastic rubber layer. For heavily-stressed industrial surfaces a third coat is recommended.

No. The substrate must be dry, clean and free of grease. Apply at +10 °C to +30 °C and relative humidity < 80 %.

Dust-dry after 2 hours at 23 °C / 50 % RH. Next coat earliest after 4 hours. Fully cured after 28 days.

Consumption per coat: 100–200 g/m². With the 2 recommended coats reckon on approx. 0.3–0.4 kg/m².

Apply at +10 °C to +30 °C, relative humidity below 80 %. Surface temperature must be at least 3 °C above the dew point. Do not apply in direct sunlight, strong wind, frost or precipitation. (Manufacturer specification, Farbex.)

The freshly applied coating must be protected from precipitation and sub-zero temperatures for at least 24 hours (manufacturer specification). Full weather and load resistance is reached after 28 days.

Yes — liquid rubber bonds to surfaces previously coated with alkyd or oil paints. Prerequisite: the old coating must be sound, clean and degreased. Sand smooth surfaces with sandpaper (grit 80–120) until matt, then wash with a mild cleaner and let dry well. Remove loose, flaking spots mechanically beforehand.

Yes. The product is made in two bases: Base A (white, for pastel and medium-saturation shades) and Base C (for saturated shades — cannot be used without tinting). Tinting manually with pigment concentrate or by machine using the NCS colour system. For saturated shades (yellow, red, orange, green) we recommend a first coat in a similar pastel shade to reduce consumption.

Mit Wasser und milden Reinigern. Nassabriebklasse 1 nach EN 13300 erlaubt regelmäßiges Wischen ohne Substanzverlust.

Under long-lasting water exposure — especially on horizontal surfaces such as flat roofs or balconies — the coloured coating can show a temporary slight whitening or opacity. This is a known phenomenon of water-based acrylic coatings. The original colour returns once the surface is fully dry — the protective function remains intact throughout. (Manufacturer specification, Farbex.)

The manufacturer's guarantee period is 36 months from the production date with proper storage. Storage conditions: +5 °C to +35 °C, protected from moisture, direct sun and frost, in firmly sealed original packaging. Use up promptly once opened.

Yes, suitable for indoor use. Current VOC content: ≤ 30 g/l (Category A/d limit for water-based: < 130 g/l — we are well below that). Low-odour, solvent-free. Ventilate well during interior application. Sanitary-epidemiologically safe (state-tested).

Recommended during application: work clothes, rubber gloves, respiratory mask and safety goggles. Ensure good ventilation for indoor application. In case of skin contact, wash off with water and soap; in case of eye contact, rinse thoroughly with running water.

No. The product must not be mixed with other paints or organic solvents (manufacturer specification). The only permitted thinner is water — maximum 5 % with brush/roller, up to 10 % only with airless sprayers. Higher dilution significantly impairs the protective function.
