How to grout slate floor tiles.

Use a grout float to press the grout into the space between tiles. Scoop some grout onto the tile floor with a trowel. 2 spread the grout over a small joint. After both sides of your sponge have grout on them rinse your sponge off and repeat the process until all joints have an appropriate amount of grout.

Press the tile into the opening on the floor. It is best to use unsanded grout for slate floors. Fill a plastic spray bottle or a small pump sprayer with grout and tile sealer and spray the slate tile evenly making sure to get the sealer on the inside edges of the tiles. Once you have done this only use the other side of the sponge and only once.

Scrape away any excess grout. Replace or reinstall any remaining damaged or lifted slate and let the floor dry overnight before grouting. Select an area 2 to 3 feet square to begin and apply the grout with a rubber faced trowel to spread the grout across the slates working it into the channels between the tiles. To avoid spreading the excess grout across your tiles use one side of the sponge to wipe along the joint.

Begin in the corner farthest from the doorway and work backwards. By sealing your slate tiles you are blocking the pores of the stone this will then enable the grout to float over the pin head sized holes on the stone not stick within the pores the grout should now be easily removed when it is applied you are now ready for grouting the slate tiles.
