Questions et réponses des clients

  • question: What is the ARDEX FLEXBONE UI 740 used for?

    répondre: The ARDEX FLEXBONE UI 740 is designed as an uncoupling waterproofing membrane and load-bearing underlayment for large-format tiles. It provides a reliable barrier that prevents moisture from penetrating the substrate while allowing for movement between the tile and the floor. This is particularly beneficial in environments like bathrooms or kitchens where water exposure is common. Using this membrane can help maintain the integrity of your tiled surfaces over time, making it an essential product for tile installations.
  • question: How thick is the ARDEX FLEXBONE UI 740 membrane?

    répondre: The ARDEX FLEXBONE UI 740 membrane is 1/8 inch thick. This thickness is optimized for load-bearing capacity while ensuring proper flexibility and support for large-format tiles. The unique structure allows for thermal movement and can accommodate the natural expansion and contraction of materials without cracking, making it ideal for both residential and commercial applications.
  • question: Can ARDEX FLEXBONE UI 740 be used on all types of floors?

    répondre: While ARDEX FLEXBONE UI 740 is versatile and suitable for various substrates, it is important to ensure that the underlying surface is clean, dry, and properly prepared. It works well on concrete, poured floors, and cement backer boards. For more specific applications, checking the manufacturer's guidelines will help ensure the best performance. Appropriate preparation leads to optimal adhesion and effectiveness in waterproofing and uncoupling.
  • question: Is ARDEX FLEXBONE UI 740 suitable for outdoor use?

    répondre: Yes, ARDEX FLEXBONE UI 740 can be used in exterior applications where large-format tiles are laid. Its waterproofing properties help protect against moisture infiltration, making it a solid choice for terraces, patios, and walkways. However, ensuring proper installation is crucial for outdoor settings to stand up against elements such as freeze-thaw cycles and UV exposure.
  • question: How should I prepare the surface before applying ARDEX FLEXBONE UI 740?

    répondre: Surface preparation is key for optimal performance of ARDEX FLEXBONE UI 740. Start by cleaning the area thoroughly to remove dust, debris, and oil. Check that the substrate is level and cure any uneven areas. If using on concrete, ensure it is fully cured. For best results, you may also apply an appropriate primer based on your substrate type which will enhance adhesion and overall effectiveness of the membrane.
  • question: What type of adhesive should be used with ARDEX FLEXBONE UI 740?

    répondre: When using ARDEX FLEXBONE UI 740, it is recommended to use a modified thin-set mortar that complies with ANSI standards. This type of adhesive allows for strong bonding to the membrane and ensures that the large-format tiles remain secure. ARDEX offers a range of compatible thin-set mortars that are designed to work seamlessly with their products, which can help simplify the installation process.
  • question: How much area does one roll of ARDEX FLEXBONE UI 740 cover?

    répondre: One roll of ARDEX FLEXBONE UI 740 covers 215 square feet. This substantial coverage makes it suitable for large projects, reducing the need for multiple rolls. When planning your tiling project, calculating the area carefully to determine how many rolls you'll need will ensure continuous coverage, which helps in achieving a uniform look and performance across the entire surface.
  • question: What advantages does the uncoupling feature of ARDEX FLEXBONE UI 740 provide?

    répondre: The uncoupling feature of ARDEX FLEXBONE UI 740 minimizes stress transfer between the substrate and the tile. This helps prevent cracking and warping over time, especially important for larger tiles that may experience significant movement. It accommodates fluctuations in temperature and moisture, ensuring a lasting and stable installation. Using an uncoupling membrane is crucial in high-stress areas like hallways or commercial floors.
  • question: How do I install the ARDEX FLEXBONE UI 740 membrane?

    répondre: Installation of the ARDEX FLEXBONE UI 740 is a straightforward process. Begin by preparing your substrate as mentioned, then roll out the membrane and cut it to fit your area. Ensure that the ribs of the membrane face upward, and then apply your modified thin-set mortar over it. Finally, press your large-format tiles into the mortar to secure them. Following the manufacturer's recommendations during installation will lead to optimal results.
  • question: Where can I buy ARDEX FLEXBONE UI 740 Uncoupling Waterproofing Polyethylene Membrane in Canada?

    répondre: You can purchase ARDEX FLEXBONE UI 740 Uncoupling Waterproofing Polyethylene Membrane at Ubuy in Canada. They offer a variety of construction and building materials, making it easy to find what you need for your project.
