NEOPROOF POLYUREA C1 polyurea waterproofing for roof, terrace or balcony

Neoproof Polyurea C1 is a two-component, extremely durable polyurea waterproofing membrane for cold application by brush, roller or airless spray. Thanks to its special formula, it can be applied in one layer (on smooth surfaces such as concrete or steel). For use as waterproofing on roofs, balconies and terraces, where mechanical resistance and excellent waterproofing properties are required. Creates a smooth (bubble-free), moisture-impermeable polyurea insulation, zero water absorption and resistance to mechanical damage. The liquid waterproofing coating based on aliphatic resins is fully resistant to UV radiation and does not require the use of additional topcoats. Rain may fall on the coating just 2 hours after application, so the product can be used in uncertain weather conditions.

Neoproof Polyurea C1 polyurea insulation - applications

The product can be applied to various substrates using an appropriate primer (read more "System primers" ).

• Concrete substrates (balconies, terraces, flat or sloped roofs)
• Roofs covered with sheet metal (steel, galvanized, aluminum, coated, previously painted with other paints)
• As a layer protecting PUR foam or hot-applied aromatic polyureas against UV radiation
• Old elastomeric coatings
• Wood
• PVC membranes

Neoproof Polyurea C1 polyurea insulation - properties

• Prevents moisture absorption, ensuring a complete seal
• It has the CE mark for concrete protection
• High resistance to bending and stretching
• Very high mechanical resistance
• UV resistance, based on aliphatic resins
• Excellent adhesion to various building materials
• Creates a blister-free coating. No holes or bubbles appear on the coating while drying
• Dries and hardens quickly
• Long service life of the mixture
• Bridges hairline cracks
• Easy to apply – it can be applied with a roller, brush or high-pressure spray. Unlike hot-applied polyureas, it does not require the use of a special unit
• Long-term protection against water - waterproofing
• An ideal solution for securing roofs, terraces and balconies with pedestrian traffic
• It remains flexible in the temperature range from -35°C to +80°C

System primers depending on the substrate to which Neoproof Polyurea C1 will be applied

Primers should be used in accordance with their technical data sheets.

Roof felt – not used on roofing felt, product for application on surfaces with an even/uniform structure.

Concrete/cementitious substrates: Acqua Primer NP - basic primer, however, due to the fact that it is water-soluble, it requires good weather conditions. Max. permissible substrate humidity: 8%. Time to repaint: 24 hours. Epoxol Primer – in unfavorable weather conditions (high air humidity, low temperature), we recommend using a solvent-based epoxy primer. Max. permissible substrate humidity: 4%. Time to repaint: 24 hours. Neodur Fast Track PR - for projects where time is of the essence and must be completed quickly. Max. permissible substrate humidity: 4%. Time to repaint: 2 hours. Neopox Primer WS - fresh concrete (minimum 2 weeks) or damp from rain, washing, etc. (the moisture comes from the outside, not from the ground), there is no time to dry the substrate. Max. permissible substrate humidity: <100%. Time to repaint: 24 hours Neopox Primer AY - if there is a problem with capillary rising of moisture from the ground (e.g. terrace on the ground with poorly made or no insulation). Max. permissible substrate humidity: 10-12%. Time to repaint: 24 hours

Black steel - Neopox Primer 815 . Neodur Metalforce rust remover 24 hours before priming .

Steel or other metal, but already painted with e.g. polyurethane or polyvinyl paint - high-gloss coatings should be matt. The substrate must be thoroughly washed with water under pressure and dried. Neoproof Polyurea can then be applied directly. If "bare" metal is discovered somewhere, these places must be properly primed. Neodur Metalforce rust remover 24 hours before priming .

Steel is factory-coated with a polyester coating - the substrate must be matt and washed with water under pressure. After drying, prime with Neopox Primer 815 . Neodur Metalforce rust remover 24 hours before priming .

Galvanized steel, aluminum - Neotex Inox Primer . Neodur Metalforce rust remover 24 hours before priming .

PUR foam, new in good condition, closed cell - apply directly, without primer, in one thick layer. The foam should have a relatively even surface so that the Neoproof Polyurea does not flow into the grooves, otherwise bubbles will form locally (the solvent will try to release itself). If there are shiny places on the foam, they need to be matt and apply Acqua Primer NP , similarly if there are any places with open pores.

PUR foam, old and in poor condition, open cells - Acqua Primer NP .

Old elastomeric coatings/membranes, such as Neoroof and Neoproof PU W-40 - wash thoroughly with water under pressure, dry and apply Neoproof Polyurea directly.

Wood - a wooden structure must be stiff and must not bend too much. Use Epoxol Primer . If the wood is highly absorbent, further priming may be necessary (after the first priming, the wood will absorb everything and will still be dull or unevenly polished).

PVC membranes - washing the substrate with THF, MEK or Neotex 1021 (in this order, from the most effective to the slowest). After slightly dissolving the membrane, apply Neoproof Polyurea directly onto the slightly sticky PVC membrane.

Hot-applied aromatic polyurea - Relatively new, in good condition - matt to remove shine, remove dust after mattifying and apply directly. Old one that has started to chalk - wash it under pressure to remove the chalking products, then apply it directly. Covered with a polyurethane membrane that protects against UV - wash with water under pressure and apply directly.
