Many home owners install tile outdoors on a patio or as a part of a garden's landscaping scheme. First you attach tiles to a flat surface with mortar; once the mortar is dry, use grout to fill in the space between each tile. Selecting a dark grout for outdoor tiles is a good idea, as it will not show dirt as quickly as lighter grouts will.
Things You'll Need
- Epoxy grout
- 2 buckets
- Grout float
Buy an epoxy grout. Epoxy grout can be challenging to work with because it has a working life of only 90 minutes, so you must apply it quickly. It is ideal for outdoor projects, however, because it does not need to be sealed and can resist mold and mildew.
Mix the grout with water in a large bucket per the manufacturer's instructions.
Spread the grout over the tiles with a rubber grout float. Apply the grout diagonally across the tile joints, pressing downward to force the grout between the tiles. Use a generous amount of grout -- it is better to wipe away the excess than to have low points in the tile joints.
Wipe excess grout away with the grout float. Hold the float at a sharp angle and move diagonally across the tiles, being mindful not to dig out any grout as you work.
Clean the surface with a wet sponge. Move the sponge in a circular motion, rinsing it out in a bucket of water periodically.
