Here’s Eileen holding a sheet of the tiles we chose for the kitchen backsplash:

Selecting a Grout Color for the Kitchen Backsplash

The next decision to make was selecting a grout color for the kitchen backsplash.

The grout is the filler material that goes in between the tiles. Grout comes in two types – sanded and unsanded.

When your tile spacing is less than ⅛”, you need unsanded grout.

Our stone tiles used ⅛” spacing, so we needed regular sanded grout.

Selecting a grout color was actually the hardest part of the the kitchen tile backsplash project because we kept changing our minds.

You don’t realize it but grout plays a big role in a tiled area, as one grout color can completely change the look of the area.

Once again we relied on our virtual showrooms of superimposed tiles to guide us on this decision.

We initially went with a dark-colored sanded grout, thinking it would match the cabinets; however, we changed our mind when we started using it because it was way too dark once mixed.

We ended up going with a grayish colored grout in the end.

Determining How to Cut the Tiles

Next, I needed a way to cut the tiles in order to tile the kitchen.

I remembered from discussions with our contractor friend that there were several ways of cutting tiles.

Option 1: I could use a hacksaw with a tungsten carbide blade. Although this was the cheapest solution, it seemed like a lot of work.

Option 2: I could use a manual tile cutter. It scores and breaks the tile for you. That sounded like a simple option.

Option 3: Then, there is a wet tile saw, which is basically a mini-table saw with a water reservoir to keep the blade wet and the tile dust to a minimum.

Coincidentally, Home Depot was having a Black Friday sale on wet tile saws, so it was hard to turn down the deal.

Admittedly, I would rarely use the saw in the future (how often am I installing tile backsplashes), but it was selling at half price and would greatly expedite progress on this project.

Pictured below is the wet tile saw ready for action.

Now, that we had our tile and grout selected (and a brand-new wet tile saw), it was just a matter of preparing the area in the kitchen and getting a mortar mix to bond the tile to the wall.

Prepping the Kitchen for the Backsplash

Prior to tiling the kitchen, I removed the small patch of red, pizza-kitchen tiles above the oven (pictured below) with a hammer and chisel.

Although they came off fairly easily and quickly, I had to be careful not to cause too much damage to the drywall beneath (the new tiles will need a sturdy and flush surface to adhere to).

Then, I prepped the area for the new tile backsplash by removing all the face plates from any electrical outlets/switches and covered the countertop with plastic.

Making the Mortar

We bought a bag of thinset, which is just a quick drying cement used for tiling.

It comes in powder form, and you just have to mix it with the right amount of water. The water/powder ratio is the trick to getting good workable thinset.

Too much water and the thinset is too runny and the tiles do not stick well to the wall during the drying period.

Too little water and the thinset gets too thick and causes difficulties spreading on the wall.

So I started with a few scoops of the powder and added in a very small amount of water. I used a paddle mixer attachment for my drill and a large bucket to stir the solution well.

My trick to getting the perfect thinset consistency was to slowly add in more and more water until I was comfortable with the result.

Once I mixed the right thickness, I let the thinset sit for 15 minutes. This wait time (called slaking) was an important step because it gave the thinset ingredients time to activate.

After the slaking period, I gave the mix one more stir, and it was ready to use.

It was time to start tiling the kitchen.

How to Install Tile Backsplash

Using a notched trowel that I purchased specifically for this occasion, I started spreading the thinset onto the drywall.

Remembering a tip from my contractor, I worked in small batches.

I only put on enough thinset to adhere one sheet of tiles at a time to the wall.

To apply the thinset, I scooped some onto a flat (non-notched) side of the trowel and spread it on the wall.

Once the thinset was spread evenly over a patch, I switched to the notched side of the trowel. I ran it across the thinset, leaving behind evenly spaced grooves.

The grooves are important to help the tiles stick to the wall. I placed a sheet of tiles on the wall and pressed each tile into the thinset.

The Importance of Tile Spacers

Here is where I made an incorrect assumption about tiling. I thought that because the tiles were already spaced on a sheet, I did not need tile spacers (little plastic wedges that help you keep your tiles evenly spaced).

However, once I adhered the sheet to the wall, shortly afterwards some of the tiles started to slide down the kitchen wall.

Luckily, I had some plastic washers that were ⅛” thick. I wedged those in between the drooping tiles to maintain the spacing.

So, I ran out later that day to get some actual tile spacers for the rest of kitchen tile project.

I also had an issue of drooping tiles, especially over areas with no countertop (like across the back of the stove). They just kept sliding downwards.

To solve this problem, I put temporary finishing nails below some of the tiles on the bottom row to give them a ledge to rest on.

However, the tiles above the countertop drooped too, and I could not have the tiles resting directly on the countertop, as I needed to have a ⅛” spacing.

Instead of using finishing nails there, I used some paint stirring sticks, which happened to be the right thickness.

At the time I thought it was a great idea, but what a big mistake it turned out to be. The next day when the thinset was dry, I tried to remove the stirring sticks. They would not budge.

They were embedded in the dry thinset, like the tiles above it. I had to use a chisel and a hammer to remove it, and even that did not do a great job.

I ended up having to use a special grout removal bit on my Dremel to grind out the wood/mortar mix in the groove between the tile and the countertop.

So note for future tile backsplash projects – always use proper plastic spacers rather than improvisation.

Making the Tile Cuts

Here’s a picture of one area of the kitchen wall, just after I applied the tile backsplash to the thinset:

By now, my newly purchased wet tile saw was really starting to pay off.

Cutting the tiles was a breeze, and all my cuts were very accurate. ​

Just like a table saw, I set the fence on the tile saw to the right distance, and slowly slid the tiles through the blade to cut them, guided by the fence.

There was practically no dust in the air, and it was fairly quiet. I could work in the garage at night and not have to worry about disturbing anyone with the noise.

Here’s a picture of me getting ready to cut one of the stones with the tile saw:

Most tiles just required one cut to fit a narrow gap.

However, several tiles required two perpendicular cuts, leaving behind an L-shaped tile. These pieces mostly wrapped around an electrical outlet or the corner of a cabinet.

To cut these, I held the tile up to where it was going. Then, I penciled in some notches on the surface to remember where to cut it.

The only problem I had with the tile saw was where the 2 perpendicular cuts met each other.

Since the blade was round, I had difficulty getting the cut lines to fully intersect without over-cutting slightly on one side of the tile (the side facing down on the saw table).

I dealt with this by making sure the back surface of the tile faced downward when cutting. The over-cut lines were not visible once the tiles were stuck to the wall.

It would have helped to have a tile snipper too.

I probably could have eliminated the over-cut problem by getting close enough with the wet tile saw. Then I could have broken off the waste part and then used a tile snipper to clean up the remaining piece.

Something to keep in mind for my next tile project, invest in a cheap tile snipper to work alongside the tile saw.

I started tiling on the area off-set by the fridge.

It was a small area, and when I was happy with that. I continued along the perimeter of the kitchen.

I finished installing the tiles in about 2 hours.

Eager to start grouting, I had to wait for the mortar to properly set, which meant letting it dry overnight.

Applying the Grout to the Tile Backsplash

The next evening, I started the grouting process.

I mixed the grout very similar to how I did the thinset. I added the grout powder to the bucket. Then, I slowly added in more and more water (mixing with the paddle) until I got a good consistency.

Afterwards, I let the mixture rest for 15 minutes to slake.

It was now time to apply the grout.

I really just used 3 tools for this process – a grout float, a sponge, and a bucket of water. I used the grout float to scoop the grout out of the bucket, and fill in between the tiles.

Also, I made sure not to get any grout into the spacing between the tiles and the countertop. That area actually requires caulking.

It would technically look fine if grout was packed in there, but there’s a good chance that grout would crack after some time.

I used a sanded caulk that was the same color as the grout.

After I packed the grout into the grooves, I let the grout sit for 15 minutes.

At this stage, the kitchen wall will look like a big mess, as the grout is wiped all over the tiles.

After the setting in period, I used a wet sponge to wipe off all the excess grout. I wiped a few tiles at a time, cleaned the sponge in a bucket of water, and repeated.

I saturated the sponge with water, but not enough so that water was dripping down the wall.  The wet sponge is what really made the difference.

After wiping down the tiles, glimpses of what the final tile backsplash looked like started to reveal itself.

Next, I gave the DIY tile backsplash another sponge cleaning 3 hours later.

This time though, I completely wrung out the sponge before each wipe, so its just barely damp when wiping the tiles.

Also, its important to perform the wipes in one continuous motion, and not backtrack over already wiped tiles.

This last cleaning process is important to help reduce the amount of  grout haze the next day when everything is completely dry.

The next day, I used a dry towel to dust off the tiles and remove any remaining haze. from the grout.

Here’s a close-up of the finished tile backsplash:​

Applying a Tile Sealer

With the grout applied to the tiles, I had almost completed the kitchen tile backsplash.

Since the natural stone tiles were porous,  I waited a few days after grouting and wiped on a tile sealer to help keep water out and protect the stones from daily kitchen use.

​All in all, it took two days to complete the backsplash, and even though I learned a few things the hard way, I successfully installed the tiles in the kitchen.

Months later, the DIY tile backsplash looks the same as the day it first went on.

It’s amazing how much of a difference the DIY tile backsplash makes. It really ties the whole kitchen together.

In learning how to install backsplash, I used new tools and added quite a few skills to my toolkit. It was a fun project to work on.

If you are looking to install your own tile backsplash, it’s really quite simple – and it turned out amazing.

As for our kitchen, it is slowly coming together. The next phase of the kitchen overhaul is painting the window trim lighter to match the newly modern feel of the kitchen.

Then, installing some pendent lighting, and finally converting the desk area to a cabinet.
