Bituminous Polyurethane Waterproofing Coating

KEY FEATURES & ADVANTAGES

• Fast curing capability.

• Allows thick-layer applications without bubble formation.

• Unmixed components remaining outside the application amount can be saved for future use.

• Excellent crack-bridging properties due to its low modulus.

• Effective resistance against chemicals.

• Outstanding adhesion to all kinds of substrates, whether primed or unprimed.

• Although thinning is generally unnecessary, it can be thinned with polyurethane thinner depending on site conditions.

• Excellent thermal resistance; the product never softens.

• Maximum service temperature is 80°C, and maximum shock temperature is 200°C.

• Cold-resistant; the film retains its elasticity down to -40°C.

• Outstanding mechanical properties, featuring high elongation, tensile, tear, and abrasion resistance.

• Functions effectively as a water vapor barrier.

• Can also be applied as a joint sealant.

• The 1/1 volumetric ratio of the components makes the mixing process simple and straightforward.

RECOMMENDED APPLICATIONS

• Gypsum and cement boards

• Polyurethane insulation foams

• Asphalt membranes

• EPDM membranes

• Bathrooms (under tile)

• Verandas and balconies (under tile)

• Cement-based roofs

• Metal or fibrous roofs

• Water tanks (excluding potable drinking water reservoirs)

• Floors

• Foundations

• Bridge decks

• Cut-and-cover tunnels

• Irrigation channels

TECHNICAL SPECIFICATIONS & ENVIRONMENTAL CONDITIONS

Environmental Application Conditions

• Relative air humidity must be a maximum of 80%, and application temperature (ambient and substrate) must be between +3°C and +35°C.

• Open areas must remain free of rain for 24 hours prior to application, during application, and for 24 hours post-application.

• Substrate temperature must be at least 3°C above the current dew point temperature. (Request the Ambient Temperature – Ambient Humidity – Dew Point Temperature chart from our company).

Compatible Substrate Types

Concrete, fibrous cement, mosaic, cement-based roof tiles, old yet well-adhered acrylic and asphalt coatings, wood, corroded metal, and galvanized steel surfaces. Please contact our technical department for other base layers.

Consumption Rate

• Minimum consumption: 1.0 – 1.5 lt/m²

SURFACE PREPARATION & MIXING

Surface Preparation

The surface should preferably be cleaned using high-pressure water; completely free from oil, grease, fuel, and paraffin residues, as well as form-release agents, cement residues, wood chips, loose particles, and cured membranes.

Mixing

Mix equal amounts of the two components either manually or using a low-speed mixer (300 rpm) and apply immediately. The pot life of the mixture is 30–45 minutes at 20°C. For airless spray applications—especially when using a low-power machine—a small amount of thinner may be required.

Application Method

Apply the material using a brush, roller, or spatula.

PACKAGING & STORAGE

• Packaging:

  • Component A: 20 kg | Component B: 20 kg

  • Component A: 200 kg | Component B: 200 kg

• Storage Information: The material must be stored in a cool and dry place. When stored properly in its unopened original packaging, the shelf life for both components A and B is 1 year.

HEALTH & SAFETY PRECAUTIONS

• Observe the Material Safety Data Sheet (MSDS) prepared in accordance with relevant EU directives.

• Although it contains no volatile organic compounds, providing adequate ventilation in enclosed environments is strongly recommended.

• Furthermore, methane gas seeping from the ground may accumulate inside tanks; this possibility must always be considered and safety precautions must be taken accordingly. Request the Material Safety Data Sheet (MSDS) from your supplier.
