ARDEX WA, classified under the BS EN 12004 R2 T designation, is recognized as an ‘improved reaction resin adhesive with additional characteristics and reduced slip.’ This solvent-free, epoxide resin-based adhesive serves both as a thin bed adhesive and grouting compound, making it ideal for environments that require chemical resistance or where traditional cement-based grouts may not be suitable. It is versatile enough to be used for fixing and grouting all types of ceramic tiles, glass, and ceramic mosaics in both internal and external applications. Once fully cured, ARDEX WA creates a decorative, waterproof joint that is resistant to weather, frost, and chemicals, accommodating joint widths from 2-12mm.

 

Key Points

  1. Classification: ARDEX WA is designated as an improved reaction resin adhesive (BS EN 12004 R2 T) with reduced slip and enhanced characteristics.
  2. Composition: This adhesive is solvent-free and made from an epoxide resin, functioning as both a thin bed adhesive and a grouting compound.
  3. Applications: It is suitable for fixing and grouting various ceramic tiles, including glass and ceramic mosaics, in both internal and external settings.
  4. Durability: Once cured, ARDEX WA provides a waterproof, weather-resistant joint that withstands frost and chemical exposure, with joint widths ranging from 2-12mm.

 

Fixing Coverage: A 4kg unit of ARDEX WA can cover approximately 1.4m² of tiles or up to 2.2m² of medium or small mosaics.

Storage and Shelf Life: Store ARDEX WA in a dry environment. When kept in its original unopened containers, the adhesive has a shelf life of at least 12 months.

ARDEX WA is particularly well-suited for use in environments such as swimming pools, showers, bathrooms, shops, abattoirs, dairies, hospitals, hydrotherapy and spa baths, sports centers, and other specialized facilities that demand high standards of hygiene and cleanliness. Once cured, ARDEX WA mortar can support full loads after just 2 days at normal temperatures, and after 7 days, it demonstrates resistance to aqueous salt solutions, chlorine, commercial cleaning agents, alkalies, and a wide range of dilute mineral acids. Additionally, the hardened mortar is resistant to common domestic cleaning agents and swimming pool detergents. However, spills from beverages like coffee, tea, and fruit juices (e.g., blackcurrant) can stain the grout if not cleaned promptly. It is important to note that ARDEX WA has not been tested according to Commission Directive 1895/2005 and should not be used in direct contact with food, such as on food preparation surfaces. Nevertheless, it is suitable for floors, walls, and other surfaces in food preparation areas where a hygienic and easily cleaned surface is essential.

 

 

Mixing

To prepare ARDEX WA mortar, thoroughly combine Hardener A with the Primary Paste W until a uniform consistency is achieved. Using a propeller-type stirrer attached to a slow-speed drill is recommended for optimal mixing. The mortar is ready for immediate use and has a working time of approximately 85 minutes at 20°C; however, this time decreases at higher temperatures and increases at lower temperatures. In hot conditions, it is advisable to spread the mortar immediately after mixing to prevent self-heating, which can shorten the working time. Ensure that application occurs at temperatures above 10°C.

NOTE: To ensure all materials are utilized, transfer some of the mixed mortar back into the hardener container (this is known as back mixing) to disperse any remaining material. Afterward, return this mixture to the main container and mix thoroughly to achieve a uniform mortar. This process helps eliminate any unreacted material, allowing the packaging to be safely disposed of as non-hazardous waste.

Fixing Technique

Ensure that the surface to which the mortar will be applied is dry, sound, and free from dust, contaminants, and other barrier materials. Suitable surfaces include concrete, cement/sand renders and screeds, rigidly fixed plywood, terrazzo, and other building materials. If there is any doubt regarding adhesion, conduct a test area.

NOTE: ARDEX WA epoxy mortar is appropriate for fixing both wall and floor tiles or mosaics. For glass or translucent tiles, or when grouting thin tiles or mosaics, use the white variant of ARDEX WA. In areas where chemical spillage is possible, the grey variant is recommended. When applying tiles or mosaics, spread the ARDEX WA mortar with a trowel, then comb it with a notched trowel to create a ribbed mortar bed (use a 5mm square toothed notched pattern for tiles and a 3mm square toothed pattern for mosaics). Press the tiles firmly into the ribbed mortar and ensure they are thoroughly bedded to maintain good contact. The tiles can be adjusted within the mortar’s working time. Grouting can take place after 12 hours at 20°C.

Grouting

Using the correct tools is crucial when applying ARDEX epoxy grouts. For details, refer to the ARDEX Tool Catalogue and ARDEX Instruction Leaflet No. 10. Employ a suitable squeegee to work the mortar into the dry joints, ensuring complete filling, particularly in joints made of natural stone or absorbent, textured, or soft glazed ceramic tiles. Consult BS 5385-1 for further guidance or contact the tile manufacturer/distributor for advice. If uncertain, carry out a trial application. For information on natural stone products, refer to the ARDEX natural stone tiling guide. Clean tools before the mortar hardens using a brush and water.
