Ensure joints are clean and free from excess adhesive. With porous tiles, dampen joints and tile edges with water (but not so wet that water remains in the joints) before grouting to avoid dehydration of the grout. Do not grout until the adhesive has set firmly. All tile spacer must be removed from joints.
MIXING
Mix 0.2L of clean, drinkable water to 1kg powder to achieve a nonsag, creamy paste. The mix should be used within 1 hour at 23°C and 50% relative humidity.
APPLICATION
Prior to grouting, it is advisable to check ease of cleaning with tiles that have a textured or matt surface.
- Work into grout joints using rubber trowel. Compact the grout firmly into the joints, minimising the amount left on the tile surface.
- Allow 10 -15 minutes before clean-up. Wipe tile surface with damp dense sponge, working diagonally across tile joints.
- If the grout is firm enough, polish the tile surface with a dry cloth or sponge, making sure no smears are left on surface.
- Clean all tools, hands with water immediately after use.
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 afterwards.
If the grout is to be sealed, allow at least 7 days before doing so.
DRYING TIME
Approximately 24 hours at 23°C and 50% RH. Allow longer for lower temperatures or high relative humidity.
