Step 1: Removing Old Kitchen Backsplash Tile
The first big hurdle is getting the old material off the wall. This step can be messy and dusty. Take your time to avoid damaging the drywall underneath.
Protecting the Area
First, protect your counters and floors. Remove everything from the countertop. Lay down heavy drop cloths or plastic sheeting over the counters and the floor near the work area. Tape the edges down well. This keeps grout dust and tile shards away from surfaces you don’t want to clean later.
Taking Out the Old Tile
We start by attacking the grout lines.
- Score the Grout: Use a utility knife or a grout saw to scrape out as much of the old grout as possible. This helps loosen the bond between the tile and the wall.
- Break the Seal: If the tile is ceramic, use a hammer and a sharp chisel. Place the chisel at a slight angle underneath a tile edge. Tap the end of the chisel gently with the hammer. Work slowly around the tile. The goal is to crack the thin-set behind it, not shatter the wall.
- Pry Loose: Once you see a gap, use a pry bar to gently lift the tile away from the wall. Be careful near electrical outlets or cabinet edges.
- Dealing with Stubborn Spots: Some tiles may need more persuasion. If a tile won’t budge, try cutting through the center of the tile with a rotary tool if you have one. Then, chip away the pieces.

Step 2: Preparing Wall for New Backsplash
A beautiful new kitchen backsplash tile installation needs a perfectly flat surface. If the wall is bumpy or damaged, your new tiles will look crooked.
Cleaning Off Old Mortar
After the tiles are gone, you will see patches of old thin-set mortar stuck to the wall.
- Use a hammer and chisel again, but this time, chip away the old mortar until the surface is mostly smooth. Use short, light taps.
- For the remaining thin layer of mortar, use a sturdy putty knife to scrape the surface clean. You need to remove any debris, grease, or soap residue. The wall must be completely clean for the new adhesive to stick well.
Repairing Damage
Inspect the exposed drywall. If you see large gouges or holes:
- Fill Holes: Use lightweight spackling paste to fill in any deep gouges in the drywall. Let the spackle dry completely according to the package directions.
- Sand Smooth: Once dry, use a sanding block to lightly sand the filled areas until they are perfectly flush (even) with the surrounding wall. Wipe all dust away with a damp cloth. A smooth, dust-free surface is crucial for good adhesion.
Step 3: Planning Your Layout
Good planning prevents wasted tile and awkward cuts. This is where you decide how the tiles will look before you mix any adhesive.
Measuring the Space
Measure the height and width of the entire backsplash area. Find the center point of the longest wall section. This center point is usually where you should start laying full tiles. Starting in the middle ensures that any small cuts you have to make will be split evenly on both sides of the counter, which looks much better.
Dry Laying the Tiles
Take a few tiles and lay them out on your countertop in the pattern you plan to use. This helps you see how the pattern flows and where cuts will fall, especially around corners or under cabinets.
- Mark Reference Lines: Transfer your center point onto the wall using a long level and a pencil. Draw a faint vertical line down the center. Draw a faint horizontal line where the bottom of the tile row will meet the countertop. These lines are your guides.
Step 4: Mixing and Applying Adhesive
The success of your DIY backsplash tile replacement hinges on the adhesive you use.
Choosing the Best Adhesive for Backsplash Tile
For most standard kitchen tile projects, a high-quality thin-set mortar is the best choice.
- What to Look For: Look for a thin-set mix specifically rated for wall tile applications. If you are using heavy stone or glass tiles, you might need a white thin-set mortar. White mortar prevents dark gray thin-set from showing through light-colored tiles.
- Mixing: Follow the instructions on the bag precisely. Add water slowly to the dry mix in a bucket. Use a drill with a mixing paddle attachment. Mix until the mortar is smooth, like thick peanut butter. Let the mixed mortar “slake” (rest) for about 10 minutes. Then, remix it briefly before use.
Spreading the Mortar
You must work in small sections because the mortar dries quickly. Only spread enough mortar for the area you can tile in about 15–20 minutes.
- Use the Right Trowel: The size of the notches on your trowel depends on the size and thickness of your tile. Smaller tiles need smaller notches. Check the thin-set manufacturer’s recommendation.
- Apply Evenly: Hold the notched trowel at a 45-degree angle. Spread the mortar onto the wall surface in smooth, even ribbons.
- Comb the Mortar: Once the ribbons are down, hold the trowel nearly perpendicular (straight up and down) and “comb” the mortar. This creates uniform ridges. These ridges provide the surface area needed for the tile to bond properly.
Step 5: Setting the New Tile
This is where your layout planning pays off.
Placing the First Tile
Start at your center vertical reference line. Gently press the first tile into the mortar bed with a slight twisting motion.
- Back Buttering: For larger tiles (over 6×6 inches) or if you notice the mortar ridges are not completely filling the back of the tile, you should “back butter.” This means applying a thin, even layer of mortar directly onto the back of the tile using the flat side of the trowel before setting it. This ensures 100% contact, which is vital for preventing cracks later.
Maintaining Spacing
You need consistent gaps for the grout.
- Use Spacers: Place tile spacers in the corners where the tiles meet. These keep the gaps uniform. For standard tile, 1/8 inch is common, but check your chosen tile specifications.
- Checking Level: After setting every few tiles, check both the vertical and horizontal alignment with your level. Adjust tiles by gently pressing them into the mortar if they are too high or tapping them lightly with a rubber mallet if they are too low.
How to Cut Backsplash Tile
Corners, edges, and outlets require cuts. This is often the most intimidating part of kitchen backsplash tile installation.
Straight Cuts:
For straight cuts, a wet saw offers the cleanest result, especially for porcelain or glass. If you don’t own one, many home improvement stores rent them or offer cutting services.
- Measure the exact distance needed, remembering to account for the width of the spacers on both sides of the cut piece.
- Mark the tile clearly.
- If using a snap cutter, score the tile deeply along the line and then snap it.
- If using a wet saw, keep the tile cool with water while cutting slowly.
Curved or Outlet Cuts:
For cutting around outlets or irregular shapes, a wet tile saw with a specialized diamond blade or a specialized tool like a tile nibbler or an angle grinder with a diamond wheel works best. Always wear safety gear when using power tools.
Curing Time
Once all tiles are set, resist the urge to touch them! Let the thin-set mortar cure completely. This usually takes 24 to 48 hours. Do not disturb the tiles during this time.
Step 6: Grouting Kitchen Backsplash
Grout fills the gaps, locks the tiles in place, and finishes the look.
Removing Spacers
Once the mortar is rock hard (24 hours later), pull out all the plastic tile spacers. Carefully scrape out any thin-set mortar that squeezed up into the joints using a utility knife or grout removal tool. The joints must be deep and clean for the grout to adhere properly.
Mixing the Grout
Grout comes as a powder that you mix with water, or sometimes as a pre-mixed paste. For DIYers, powder grout is common.
- Mix according to the bag instructions. Aim for a consistency similar to thick toothpaste. It should hold its shape on the trowel but still be spreadable. Let it slake for 5–10 minutes, then remix.
Applying Grout
Work in small sections again.
- Loading the Float: Scoop a manageable amount of grout onto your grout float (a hard rubber pad with a handle).
- Forcing it In: Hold the float at a 45-degree angle to the tile surface. Press the grout firmly into the joints, moving diagonally across the tiles. This diagonal motion forces the grout deep into the gap.
- Removing Excess: Once the joint is filled, tilt the float to a near 90-degree angle and drag it across the tile surface, skimming off the excess grout.
Cleaning the Haze
This is the trickiest part of grouting kitchen backsplash.
- Wait for Setting: Let the grout set up for about 15 to 30 minutes. It should feel slightly firm to the touch in the joints.
- First Wash: Use a large, clean sponge dampened with clean water (not soaking wet!). Gently wipe the tile surface in circular motions to remove the bulk of the grout haze. Rinse your sponge frequently in a bucket of clean water. Change the water often!
- Second Wash: After about an hour, a faint haze might appear on the tile. Use a fresh, almost dry sponge to lightly buff this haze away. Don’t press hard, or you will pull grout out of the joints.
Allow the grout to cure for the time specified on the package, usually 48 to 72 hours, before proceeding to the final step.
Step 7: Sealing Kitchen Backsplash Tile and Grout
Sealing is a vital final step, especially in the kitchen where grease and water are common.
Why Sealing Matters
Grout is porous, meaning it easily absorbs stains like wine, coffee, or oil splatter. Sealing the grout creates a barrier, making cleanup easy and keeping your new backsplash looking new longer.
The Sealing Process
- Ensure Grout is Dry: Make sure the grout is fully cured (usually 48–72 hours, check the product).
- Apply Sealer: Purchase a high-quality grout and tile sealer. Use a small brush or applicator to carefully apply the sealer only to the grout lines. Try to avoid getting too much sealer on the face of the tile itself, although most modern sealers are safe for most tile types.
- Wipe Excess: After the recommended dwell time (often 5–10 minutes), wipe any excess sealer off the tile surface with a clean cloth before it dries.
- Reapply: Most penetrating sealers require a second coat for maximum protection. Wait a few hours between coats.
Congratulations! You have successfully completed your DIY backsplash tile replacement.
Tips for Longevity and Maintenance
To keep your new tile looking great, follow these maintenance tips:
- Immediate Cleanup: Wipe up spills immediately, especially acidic liquids like lemon juice or vinegar.
- Regular Cleaning: Use a mild, pH-neutral cleaner specifically designed for tile and grout. Avoid harsh chemicals that can break down the sealer.
- Re-Sealing Schedule: Plan to re-seal your grout every 1 to 3 years, depending on the sealer used and the traffic/moisture level in your kitchen.
FAQ Section
How long does it take to replace a kitchen backsplash?
For an average 30-square-foot backsplash, the actual labor time (removal, prep, setting tile, grouting) usually spans 2 to 3 full days of active work. However, you must factor in 2–3 days for drying and curing time between steps. If this is your first time, budget at least 4 full days to allow for a slower, careful pace.
Can I tile directly over existing kitchen backsplash tile?
Sometimes, yes, you can tile over existing tile, but only under specific conditions. The existing tile must be clean, dull (not glossy—sand it if necessary), flat, and firmly adhered to the wall. If the existing tile has a very uneven or bumpy surface, it is always better to remove it completely, as outlined in Step 1, to ensure a professional finish for your kitchen backsplash tile installation.
What is the difference between thin-set mortar and mastic adhesive?
Thin-set mortar (cement-based) is mixed with water and is generally stronger and more water-resistant than mastic (a pre-mixed, sticky adhesive). Mastic is sometimes used for small, light tile projects, but for reliable, long-term kitchen backsplash tile installation, especially behind a stove where heat and moisture fluctuate, thin-set mortar is the recommended best adhesive for backsplash tile.
What is the easiest tile to install for a DIY beginner?
Subway tiles (3×6 inches) or simple square tiles are the easiest. They are easy to handle, require simple straight cuts, and their uniform size helps hide minor imperfections in the wall prep. Glass mosaics that come pre-mounted on mesh sheets are also excellent for beginners as they speed up placement.
