Area of Applications

• Concrete roof slabs and terraces.
• New and existing roofs and walls.
• Exposed exterior waterproofing applications.
• Car porch roofs and suitable deck areas.
• Tile roofs and suitable tiled surfaces.
• Fiber cement boards and suitable building boards.
• Metal surfaces and gutters.
• Fire walls and other suitable waterproofing applications.

Application

• Stir hahne PU-XSEAL ULTRA thoroughly before application to ensure a uniform and homogeneous material.
• Apply hahne PU-XSEAL ULTRA using a suitable brush or roller in two uniform coats, maintaining the recommended consumption for achieving the required dry film thickness.
• Apply the first coat uniformly over the primed substrate, ensuring that the material is evenly distributed without excessive build-up, pinholes or missed areas.
• Where reinforcement is specified as part of the waterproofing system, immediately embed the recommended non-woven polyester reinforcement into the first coat while the material is still wet. Use a suitable roller to ensure proper wetting of the reinforcement and to remove trapped air or wrinkles.
• Allow the first coat to dry adequately before applying the second coat. The second coat should be applied uniformly and preferably in a direction perpendicular to the first coat to ensure consistent coverage.
• Ensure that the required total dry film thickness is achieved after completion of the specified coats. Additional material may be required depending on substrate porosity, surface profile and site conditions.
• Protect the freshly applied coating from rain, water, dust and other contamination until it has sufficiently dried.
• Avoid application when the ambient or substrate temperature is below 5°C or above 35°C, and do not apply during foggy conditions.
