Outdoor tile is made from a variety of materials and makes durable flooring options for patios and walkways. However, since the tile is exposed to the elements and rainfall sealing them is required for protection. Applying the proper sealant to outdoor tiles makes them last longer and makes them easier to clean dirt and mud off of. It's best to seal the tile before installing the grout to prevent the grout from staining the tile.

Sweep the top of the tiles thoroughly with a broom to remove any dirt or sand that was brushed onto it during the installation.

Open a can of tile sealer that is designed for the type of tile that you have installed. Pour some of the liquid into a paint tray and insert a paint roller into the sealer. Squeeze out as much of the sealant as possible at the top of the paint tray. You don't want to create any drips during the application process.

Screw an extension handle onto the roller and roll it over the entire tiled surface making sure to cover each tile thoroughly. Do not push down on the roller since this causes the sealant to drip down between the tiles and my interfere with the grouting process later.

Re-roll the entire floor a second time but do not add any additional sealant to the roller. Concentrate on removing any pooled areas or puddles of sealant on the tile.

Wait 24 hours to allow the sealant to dry before walking on it or proceeding with the grouting process. If needed, block off the tiled area during this time so children and pets do not access the area.


Apply another layer of sealant to the tiled area once the grout is fully cured to protect it from developing stains.
