At this point, you should have the damaged porcelain floor tile removed from the floor. You are now ready to proceed with replacing the damaged tile with a new one. Here are the basics of how to finish the process of replacing a porcelain floor tile.
Step 1--Apply Adhesive
In order to install the new tile, you will need to apply adhesive to the back of it. You should know that you have options when it comes to what type of adhesive you can use for this project. Some people prefer to use thinset that comes in powder form in large bags. Others prefer to use mastic that is already mixed up in buckets. Both options will stick the tile to the floor. However, in most cases, your job will be easier if you use mastic. For one thing, you do not need to use a large bag of thinset for only one tile. Mastic usually comes in smaller buckets and is perfect for this size of a job. In addition to that, it is already mixed up and you will not have to worry about adding the wrong amount of water.
Take your trowel and get some adhesive onto it. Take the trowel and apply the adhesive to the back of the new tile. Scrape the adhesive across the back with your trowel and make sure to remove all of the excess adhesive. You should now have some straight grooves in the adhesive across the back of the tile. Make sure that you do not leave any gaps in the adhesive as this could cause problems once you get the tile installed. If there are gaps, you could potentially break the tile when you walk on it.
Step 2--Install the Tile
Now that you have adhesive on the tile, you can put it into place. Hold the tile on the edges and put it down into the hole. Make sure that you are very careful during this process so that you do not break the new tile or any of the surrounding tiles. You also want to make sure not to get any of the tile adhesive on anything else.
Press the tile firmly down into the ground so that the tile is down into the adhesive. Put a level on top of the tiles to make sure that they are level with the rest of the floor. You may need to press down on one end of the tile harder in order to level out a bit. After you have installed the tile, let it sit overnight before moving on with the process.
You can then apply grout to the grout joints around the tile. Take a grout float or trowel and use it to apply the grout. Fill up the joints with grout and try to get the excess grout off with your trowel.
Step 4--Clean Up
Take a bucket of water and a sponge and use it to clean the tile. You will be able to remove extra grout that is on top of the tile as well as smooth out the grout joints.
