Top Tips To Apply Grout On Tile

Applying tile adhesive and grout may seem intimidating but these top tips will help you make tile adhesion using grout a breeze –

1. The essential first step is to choose the best and right grout for your particular project. This can make or break your project, as every mortar is different, and thus choosing the right grout is an important step. 

2. You can follow the manufacturer’s instructions for the chosen grout to make the perfect consistency for an even application on the tile surface. The amount of water is crucial when mixing mortar and can largely impact your efforts. 

3. You can apply pre-mixed mortar evenly on the tile surface using a ladle/spade or a wooden/plastic spatula. Make sure the grout is spread evenly between and under the tiles to make sure and fill in the gaps. 

4. It may set quickly so apply it to a small section at a time. It is also advisable to prepare a small mixture first and use it all before making the next batch. This is to save some effort by mixing grout in the correct consistency needed and no product is wasted in the process. 

5. While it is still setting and the mortar is still wet, it is the best time to clean up. You can use a wet/damp cloth or a small amount of water to wipe/clean off the extra unsanded grout on new tiles. Once dried the grout cannot be cleaned up that easily. 

6. To obtain uniform and clean grout streaks for your tiles, use a damp sponge to clean up. 

7. Once completely dried, you can apply an even coat of acrylic sealer or hardener on the tiles on sanded grout to obtain a sheen finish, protect the tiles and also make them stain resistant. 

8. It is very difficult or almost impossible to clean or make crisp lines with the tile mortar once dried, so all clean-up and grout lines should be made when the mortar is still wet. 

9. Use of a wall tile primer can help before applying indoor & outdoor tiles and grout. 

10. You can define the grout borders during the initial wash and use a soapy solution for the final wash post an hour of the initial wash.
