Ardex S7 Plus: Premier Waterproof Coating for Swimming Pools

Product Overview: Ardex S7 Plus is a high-performance waterproof coating designed for swimming pool floors and walls, ensuring a robust base before installing ceramic tiles with an appropriate Ardex Tile Adhesive. Suitable for both interior and exterior use, this fiber-reinforced coating offers superior strength, flexibility, and excellent slump resistance, enduring up to 5 bar of water pressure.

Key Features:

  • Versatile Use: Ideal for both indoor and outdoor applications.
  • Enhanced Durability: Fiber-reinforced for exceptional strength and flexibility.
  • Water Pressure Resistant: Withstands up to 5 bar of water pressure.
  • Easy Application: Water-based and easily applied with a trowel for a smooth finish.
  • Packaging: Available in convenient 15kg bags.

Mixing Instructions: For optimal results, mix a 15kg bag of Ardex S7 Plus with 4 liters of water to achieve a slump-free mortar. Utilize a mixing paddle with a 10mm chuck, variable speed (at least 650 rpm) electric drill for efficient mixing. Allow the mixture to stand for 2-3 minutes, then remix to improve consistency. The prepared mortar has a pot life of approximately 60 minutes at 20°C, with variations based on temperature and mix thickness.

Application Process:

  1. Initial Application: Use a 4mm x 4mm toothed and notched trowel to apply Ardex S7 Plus to the prepared surface. Immediately flatten the ribs to create a smooth surface.
  2. Coat Thickness: Apply at 1.2mm wet thickness, drying to 1mm.
  3. Porous Surfaces: For highly porous surfaces, apply an initial layer to fill pores, allow to harden, then proceed with the first coat.
  4. Second Coat: Apply the second coat after the first has hardened (approximately 4 hours at 20°C).

Special Considerations:

  • Movement Joints: Extend any movement joints in the substrate through the Ardex S7 Plus to the tile surface.
  • Sealing Tapes and Collars: Apply Ardex sealing tapes and collars into the fresh first coat, allow to harden, then apply the second coat.
  • Localized Fillings: For filling holes, thicken Ardex S7 Plus before applying the two coats.
  • Junctions and Corners: Seal wall-floor junctions with Ardex SK-12 tape, internal corners with Ardex SK-90 Angle tape, and external corners with Ardex SK-270 Outer Angle tape. Seal cracks and joints with Ardex SK-12 Sealing Tape and pipes with Ardex SK-W or SK-F pipe collars.

Drying and Hardening: Allow the second coat to dry (approximately 4 hours) before commencing tile fixing.

Tile Fixing: Fix tiles using an appropriate Ardex Tile Adhesive and grout with a suitable Ardex Tile Grout.

Coverage: A 15kg bag covers approximately 6.25m² with two coats. Material requirement is 1.2kg/m²/1mm dry (1.2mm wet).

Technical Data:

  • Consistency: 15kg powder mixed with 4L water; reduce water for thicker consistency.
  • Weight of Freshly Mixed Mortar: Approximately 1.3kg/L.
  • Material Requirement: 1.2kg powder/m² for 1.2mm wet thickness (1mm dry).
  • Working Time: Approximately 60 minutes at 20°C.
  • Walkability: Approximately 4 hours at 20°C.
  • Packaging: 15kg net bags.
  • Storage: Store in dry conditions, in original sealed packaging, for up to 6 months.
