CERESIT® CP 30, used for quick repairs of flat and pitched roofs as well as for permanent waterproofing of flat roofs as a finishing coat. Suitable for mineral substrates - concrete, screed, fiber cement boards, roof tiles, bituminous substrates (roofing membranes and coatings), acrylic roof coatings, metal coatings (copper, zinc, aluminum, stainless steel, brass), plastic (ventilation pipes connection, drains or skylight frames), thermal insulation layers (PU foam, EPS) and wood materials (OSB, chipboard, solid wood).Available pack size: 1 kg, 5 kg
Absorbent substrates: Mineral substrates and wood have to be cleaned mechanically. Mechanically remove algae and lichen as well as loose particles and coatings. Bitumen: Thoroughly remove any loose stone chips and sand as well as the weather-worn bitumen. After that, prime the substrate with CERESIT CP 29 Aquablock Primer. Metals: Completely remove any oxide layers (patina) and clean with a solvent-based cleaner e.g. spirit. A priming coat is not required. Plastic materials: After mechanical roughening clean the plastic materials with a solvent-based cleaner, e.g. spirit. Then pretreat with CERESIT CP 29 Aquablock Primer.PUR / EPS board: Very smooth substrates have to be roughened slightly and after cleaning the grinding dust CERESIT CP 29 Aquablock Primer must be applied before CERESIT CP 30.
CERESIT CP 30 Aquablock Coating is ready-to-use and can be applied directly by means of a paint brush, roller, ceiling brush or by using the airless spraying technique. CP 30 Aquablock can be used for 3 types of coating application: Substrate protection - UV resistence - 1-1,5mm layer. Sealing coat - Soak a short-pile roller in CP 30 Aquablock Coating and roll the fleece down into the first coat so that it is fully embedded. Wait until the first layer has fully dried (waiting time approx. 24 hours, depending on the weather) before applying the second coat. Walkaways for roof inspection and maintenance - It is recommended to use a contrasting color for these areas and a layer thickness of 0 mm. Sprinkle quartz sand (e.g. grit 0.1– 0.4 mm) into the fresh top coat of the service walkways to prevent slipping.
Use CERESIT CP 30 Aquablock Coating only in dry weather with material and air temperatures of +10 °C to +30 °C and below 75% relative air humidity. The substrate temperature must be between +5 °C and +50 °C. When working in cold weather, make sure that the substrate temperature is at least 3 °C above the thaw point; otherwise a separating moisture film will form. Do not use CP 30 Aquablock Coating on transparent plastics (e.g. Plexiglas®, Makrolon®, PETG) used e.g. for domelights/skylights.
CERESIT CP 30 Aquablock can be used on these substrates: mineral substrates (e.g. concrete, screed, fiber cement boards, roof tiles), bituminous substrates (e.g. roofing membranes and coatings), acrylic roof coatings, metals (e.g. copper, zinc aluminum, stainless steel, brass), plastics (e.g. connections to ventilation pipes, drains or skylight frames), thermal insulation layers made (e.g. of PUR, EPS), wooden materials. CP 30 is especially suited for the reconstruction and repair of leaks, roof connections and pipe penetrations.
CERESIT CP 30 Aquablock can be used for absorbent substrates such as mineral substrates (e.g. concrete, screed, fiber cement boards, roof tiles), bituminous substrates (e.g. roofing membranes and coatings), acrylic roof coatings, metals (e.g. copper, zinc aluminum, stainless steel, brass), plastics (e.g. connections to ventilation pipes, drains or skylight frames), thermal insulation layers made (e.g. of PUR, EPS), wooden materials. It would be ideal to combine CP 29 Aquablock primer when preparing the mineral, bituminous, plastic or PUR/ EPS substrates (metal as an exception).
The application of CERESIT CP 30 should be carried out under dry conditions at a temperature substrate and environment of +5°C to +25°C and humidity below 80%. The drying time is about 3 hours, with poor weather conditions significantly extending the drying time. Tools can be cleaned and product residues removed with water when still fresh. Use up open buckets quickly.
