Grouting isn’t hard when you follow our simple step-by-step instructions for a professional-looking job.
While tiles themselves are impervious to water, moisture would still be able to make its way under or behind them unless the gaps between tiles are sealed with the right grout. Grouting your tiles also helps to strengthen the whole installation.
Follow our simple steps:
Step 1 You can grout your tiles after your adhesive has completely dried. This is normally 24 hours with normal adhesive but may be longer in cold areas or when tiling over a waterproofing membrane.
Step 2 Before beginning, remove all grout spacers or protruding levelling system components. Carefully remove any excess adhesive that may have filled the space between the tiles.
Step 3 Mix the flexible grout to the consistency of a thick creamy paste following the manufacturer’s instructions. Dampen (not wet) the joints with clean water before grouting to ensure correct curing.
Step 4 Apply the grout to the wall or floor with a rubber grouter using a driving diagonal motion, pushing the grout firmly into the joints leaving no air pockets or voids. Don’t worry about only grouting individual joints, just go over the whole surface. Do not apply the grout to the corners where walls meet floors or where two walls meet. This will be a movement joint that you will need to fill with silicone later. Leave as little grout on the surface of the tiles as possible. A handy hint is to start in a small section until you're confident.
Step 5 Allow the grout to dry and for a film to form on the face of the tiles. This should take about an hour. If you clean too soon before the grout has a chance to dry, you risk removing grout from the joints. Once the grout has become slightly powdery on the surface, remove the excess grout on the tiles with a clean, damp sponge by wiping across the tile diagonally to the joint. Turn the sponge over and repeat. Rinse and squeeze and keep repeating. Do not wash or overly wet the surface. The trick is to lift the film without wetting the actual grouted joint. Make sure that you wipe on a 45-degree angle and keep rinsing and squeezing out the sponge in clean water as you go.
Step 6 After most of the grout has been removed from the tiles, allow the tiles to dry until a slight haze appears on the tile surface. Give them another once-over with the damp sponge. Then carefully buff over the tiles with clean, dry cloths and a doodlebug. Do not allow grout haze to dry and set on the tile surface.
Step 7 Once the tiles are completely clean, we recommend applying a grout sealer to increase water resistance and for easier maintenance.
