the pro guide

Clean the surface thoroughly to remove dust, grease, algae and loose particles — use a pressure washer (max. 120 bar) or wire brush where needed. On highly absorbent substrates, prime first with RubberPaint thinned with 5–10% water. Fill cracks wider than 3 mm with sealant or filler beforehand, and strip back any old, flaking coatings completely.

On roofs, balconies and terraces, embed reinforcement fleece (polyester fleece 60 g/m² or glass-fibre fleece) into the wet first coat at every transition, internal and external corner, roof penetration, chimney, drain and wall junction. Saturate the fleece fully and work out any bubbles — overlaps at least 5 cm. These watertight detail points account for 80% of the long-term service life.

Apply with brush, lambswool roller or airless sprayer (15–18 MPa, nozzle 0.017"–0.023"). Consumption approx. 100–200 g/m² per coat, depending on substrate porosity.

The first coat is dust-dry after approx. 2 hours at 23 °C / 50 % RH. Apply the next coat only after the previous one is fully dry — otherwise bubbles form.

Apply undiluted for full protective thickness. Rain-resistant after 24 h (manufacturer specification), carefully walkable after 24 h, fully load-bearing after 28 days.
