How to Use Ardex WJ50 Cementitious Coloured Wide Grout Joint - 5kg Quantity:

• Ardex WJ50 Cementitious Coloured Wide Grout Joint - 5kgs powder is added to clean water in a clean container whilst stirring thoroughly to give a lump-free, firm, low-slump mortar.
• Allow to stand for 2 minutes and remix prior to application.
• A 20kg bag of ARDEX WJ 50 requires approximately 3.6 litres of water. Grout may be re-stirred occasionally, but do not add additional water.
• The pot life of the mixed mortar is approximately 1 hour at 23°C and 50% relative humidity.
• For swimming pools and use over timber floors, mix ARDEX WJ 50 Off White with approximately 4 litres of undiluted ARDEX Grout Booster.
• For 20kg bags, multiply measurements by 4x. However, we recommend working in batches of 5kg.

APPLICATION

• Work the grout into the joints using a rubber trowel.
• Compact the grout firmly into the joints ensuring they are completely filled, minimising the amount left on the tile surface.
• Allow the grout to firm up in the joint before clean-up.
• Wipe the tile surface with a damp dense sponge, working diagonally across tile joints.
• Use a minimum amount of water to avoid water float and/or shade variation, efflorescence, and shrinkage.
• Any dry film remaining on the tile surface can be removed when the grout has hardened in the joints by polishing the tile surface with a dry cloth, making sure no smears are left on the surface.
• For best results in warm conditions, keep the joints damp with clean water after hardening begins to ensure correct hydration/curing.
• In exterior conditions, it is essential to provide protection from all extremes of climate during the whole fixing and grouting operation and for as long as possible afterward.
• All tools should be cleaned with water immediately after use.

DRYING TIME

Approximately 24 hours at 23°C and 50% relative humidity. Grout joints can be sealed once fully dried, usually after 24 hours. Allow longer for dense tiles, lower temperatures, or high relative humidity.

NOTE: Do not use Ardex WJ50 Cementitious Coloured Wide Grout Joint for chemical resistant joints, use ARDEX epoxy grouts.
