How to Fix Loose Outdoor Tile

I (Vicki) rarely use the front steps at my house so I was unaware of a problem. When I finally did happen to use them, there was an unmistakable hollow sound when I stepped onto the first tile indicating a situation!

I then checked the tile I had just stepped on and it came up with no effort as did the next two tiles.

We thought this would be a quick fix since there were only three loose tiles, but as we investigated, we found that almost ALL the tiles on the first two steps were loose.

This fix had now turned into a major undertaking!

This was certainly the most labor-intensive part of the project. We first removed all of the loose tiles and set them aside for reuse. In the picture, we removed all the tiles on the first step and most of the second.

We initially left those tiles on the second step but decided removing them would be easier than working around them.

After we removed the mortar from the first step, we realized the next set of tiles and the ones on the second step were loose.

We used a Bosch rotary hammer drill fitted with a chisel blade to remove the old mortar as well as the tiles that were still stuck but needed to be removed.

We found the easiest way to use the Bosch was to hold it upside down while sitting on a short stool. It was less fatiguing that way. We also used a wet/dry vac to help contain the dust. We are both wearing protective gear including a respirator mask to protect against the dust.

We wanted to reuse as many of the tiles as possible. We first chipped off the old grout and cleaned up the backs before cleaning the fronts. I used a Mold Armor mold product that helped clean off all the old mold. Once dry we were ready to retile the front steps.

We mixed up the mortar following the instructions on the bag. We added too much water initially so we had to add more powder. Start with a little water and slowly add to it to better control the consistency. The mixer attachment to the drill was extremely helpful. Again, use appropriate protective equipment so you're not breathing in the mortar dust.

The mortar is spread in a skim coat with a notched trowel. This size trowel was suggested for the large tile we are installing.

We did not cut any tiles at this point but just laid back the ones we could reuse. We used spacers between the tiles to get the spacing but removed them to get the final placement needed for the tiles.

We didn't want to purchase a tile saw so we researched ways to cut porcelain tiles using what we already own. We used a Ryobi battery-powered 5 1/2-inch saw with a Ridgid flooring blade. We used a Makita track saw rail to use a guide to get straight cuts.

This arrangement worked very well. I followed along with the wet/dry vac to help with dust collection. Again, wear protective gear.

Even the very thin pieces of tiles were successfully cut with this method.

We took a piece of the old grout to the store to pick out the new grout. There was a handy chart that helped us to pick the perfect color.

We mixed up the grout according to the package directions. Steph used a rubber grout float to apply the grout. I followed up by cleaning the grout from the tiles with damp sponges and damp microfiber cloths.

Once the grout had cured for three days, we went back and sealed the grout with a commercial grout sealer which should help with stains.

We consider this fix a success as the outdoor steps look virtually the same as before!

This was our first tiling project and one we were not sure we could or should undertake. It was with the encouragement from a very knowledgeable associate at the Home Depot who gave us excellent advice on the tools and materials we needed that we decided to move forward.
