ARDEX A 48 - 20kg bag

Rapid-Setting Screed Mix

• Product Type:

  • Rapid-setting, flexible cement-based tile adhesive designed for use in interior and exterior applications, ideal for bonding ceramic, porcelain, and natural stone tiles.

• Size:

  • 20kg bag, suitable for medium to large-sized tiling projects.

• Colour:

  • Available in grey and white.

• Formulation:

  • Rapid Setting: Designed to provide fast-setting properties, enabling quicker tile installations. Tiles can be grouted after 3-4 hours of installation.
  • Flexible: Formulated with enhanced flexibility, making it ideal for bonding tiles in areas that may experience movement (such as timber substrates or underfloor heating).
  • High Bond Strength: Offers strong adhesive properties, ensuring that tiles stay firmly in place over time.
  • Polymer-Enhanced: The addition of polymers enhances adhesion, providing superior bonding strength and flexibility.
  • Cement-Based: Provides excellent durability and longevity for both residential and commercial tile installations.

• Applications:

  • Tile Types: Suitable for bonding a wide range of tiles, including ceramic, porcelain, stone, and terracotta, to substrates such as concrete, cementitious surfaces, and cement boards.
  • Interior and Exterior: Ideal for both interior and exterior applications, including wet areas like bathrooms, kitchens, and laundry rooms.
  • Wet Areas: Suitable for use in wet areas, providing a water-resistant bond for tiling in shower walls, bathroom floors, kitchens, and even outdoor tiling projects.
  • Substrate Compatibility: Perfect for bonding to concrete, cementitious screeds, plasterboard, and existing tiles (after proper preparation).
  • Underfloor Heating: Well-suited for use with underfloor heating systems, providing flexible bonding that can accommodate thermal expansion and contraction.

• Performance:

  • Rapid Set: Initial setting time is very quick, making it ideal for tight project timelines. Tiles can typically be grouted after just 3-4 hours, reducing project completion time.
  • Water-Resistant: Provides a water-resistant bond, making it ideal for use in areas exposed to moisture and humidity.
  • Non-Slump: Non-slump formula allows it to be applied on vertical surfaces without tiles slipping or sliding.
  • Open Time: Approximately 15-20 minutes, allowing time to position and adjust tiles after application.

• Curing Time:

  • Full curing is achieved in approximately 24 hours, but the adhesive sets enough to allow grouting after just 3-4 hours.

• Coverage:

  • Coverage is approximately 4-6m² per 20kg bag, depending on the trowel size, tile size, and substrate conditions.

• Temperature Range:

  • Can be used in temperatures between 5°C and 35°C for optimal performance.
