ARDEX Swimming Pool Tiling System

The ARDEX Swimming Pool Tiling System is designed to prevent deterioration of the cementitious tiling products, and utilises polymer-modified, sulfate-resistant adhesives and grouts to ensure a long-lasting tiled pool. ARDEX WPM 300 (HydrEpoxy 300) is a two component water based epoxy polyamide membrane/barrier coating. Approved for use with potable (drinking) water; independent testing confirms conformity with the requirements of AS4020.2005 and SS375-2001.

ARDEX EG 15 is a high-performance epoxy grout designed for situations that require strict standards of hygiene, high chemical and physical resistance. ARDEX EG 15 is exceptionally easy to clean up during application. It can be used in joints up to 15mm wide on walls and floors.

  • Screed: ARDEX A 48
  • Barrier Coating: ARDEX WPM 300
  • Waterproofing: ARDEX WPM 002
  • Tile Adhesive: ARDEX X 18 OR ARDEX E 90
  • Tile Grout: ARDEX FS-DD + ARDEX Grout Booster (for chlorine pools) OR ARDEX EG 15 (for pools containing stronger chemicals such as magnesium)
Key Features

ARDEX EG 15 Key Features:

  • ARDEX EG 15 has high chemical resistance for pools using strong chemicals
  • ARDEX EG 15 is resistant to magnesium salts, unlike cementitious grouts
  • ARDEX Grout Booster prevents staining and efflorescence, improves adhesion
  • Two-part, premium tile adhesive is ideal for immersion applications

ARDEX WPM 300 Key Features:

  • Non-flammable and negligible odour
  • Can be applied to damp surfaces
  • Can be safely applied to freshly laid hardened (green) concrete
  • Conforms to the requirements of Australian Standard AS4020.2005
  • When applied directly to the substrate the cured membrane will withstand 250kPa of hydrostatic pressure which is equivalent to a 25 metre head of water
  • Can be overcoated using almost any decorative or industrial finishing paint
  • Prevents rising damp and the formation of efflorescence when used as a single coat barrier coat
  • Has excellent adhesion to most substrates including brick, masonry, concrete block, concrete, stone and timber
  • Easy clean-up using water
Tile Ancillaries
Scope of Use
  • Swimming pools and hydrotherapy pools
  • Ideal for use with all ceramic tiles, porcelain and natural stone
  • Suitable in areas that require high standards of hygiene and chemical resistance
  • Suitable for wall and floor applications
  • Adjustable viscosity to suit application conditions
  • Pools using chlorine, sodium chloride, boron, or magnesium chloride
Limitations on Use


  • Tiling can commence after 24 hours cure of ARDEX WPM 300 although should not exceed a maximum of five days. Installer is to ensure that there is no surface contamination during this period. Sand blinding of the wet ARDEX WPM 300 surface with ARDEX primer sand eliminates these timing issues and is good practice for external tiling jobs
  • The product should be applied whilst the surface temperature is between 10–35˚C. The product will cease to cure below 10˚C. Curing time will also be adversely affected in situations where relative humidity is >85%
  • In enclosed areas, ventilation must be provided during curing cycle to enable adequate evaporation of the water. Care should be taken when sandwiching adhesives between ARDEX WPM 300 (HydrEpoxy 300) and floor coverings to ensure the water vapour transmission of the covering is sufficient to allow the solvent to escape
  • ARDEX WPM 300 (HydrEpoxy 300) is not classified as a trafficable membrane
  • ARDEX WPM 300 is hazardous and may cause sensitisation by skin contact
Other Performance Attributes
  • Low VOC
  • Solvent free
  • Water wash-up for easy cleaning
