When all the tiles have been fixed, leave them for at least 12 hours before grouting. Don’t walk on them during this time since any disturbance may affect the bonding of the adhesive. If you used card or matchsticks for spacing, remove them after 24 hours. It is a good idea to wait for 24-48 hours before grouting. Most tile manufacturers recommend a powder grout which has to be mixed with water to a creamy consistency. Mix only enough to last for about 40 minutes since it becomes unworkable after that time.
Cover a small area at a time and rub the grout into the joints with a sponge or the straight side of a notched spreader, making sure all joints are filled. Leave the grout to harden in the joints for about 30 minutes before wiping off the surplus with a dampened cloth. Wipe away all traces of grout from the tiles, rinsing frequently with clean water. You can blend the grout with the tiles by colouring it: mix grout colour mix with the grout powder before adding water. Try to avoid washing the floor for a week or two, since water may dilute the adhesive and affect the strength of the bond.
