Outdoor tile is made to be sturdy, and to withstand a great deal of exposure from wind, rain, snow, and other elements. However, just because this tile is built to last for a long time, does not mean that it won't require some protection on your part. Over time, it's common for outdoor tile to suffer from a wide variety of different problems, including staining, cracking, and more. By sealing your outdoor tile, you help to protect it against damage and extend its life. Read on for additional information on how to go about sealing your outdoor tile.

Step 1 - Clean Off the Tile

Use your broom and dustpan to clean any debris off of the surface of the outdoor tile. You should ensure that the tiles themselves are completely clean, before you attempt to seal up the tile. This will protect the appearance of the tile, and help to be sure that there won't be any dirt or other debris caught under the layer of sealant.

Step 2 - Apply the Sealant

Use a paintbrush to apply a thin layer of the tile and grout sealer solution to the surface of a tile. Be sure that the layer of sealant covers the entire surface of the tile, and that it's even throughout. Also, be sure that the sealant does not drip down off of the top of the surface of the tile onto the grout. Allow the sealant to dry overnight, before you continue with the procedure. This will help to ensure that the coloration of the tile is not affected by the application of additional grout.

Step 3 - Apply the Grout

Mix up a batch of the grout and trowel it into place in the seams between the tiles. Use the float to smooth the grout into the gaps between the tiles. Clean off any extra grout that stands out above the surface of the tiles. After approximately 15 minutes, wipe down the grout with a wet sponge. After about an hour, clean off the surface of the grout with the cloth. Allow the grout to dry completely, which typically takes about two days, before continuing.

Step 4 - Seal the Grout and Tiles

You'll now need to seal up the tiles once again, this time with the grout as well. Use a paintbrush to apply an equally thin layer of grout and tile sealant solution to the surface. Make sure that the solution covers all parts of the tile and the grout in between tiles as well. Allow the sealant to dry overnight once again.

If desired, you can repeat the final step in this procedure, in order to provide an added layer of protection for your tiles and grout. All of the materials and tools necessary for this project are available at your local hardware store and home improvement center.
