Installing a glass subway tile backsplash can add a touch of elegance and visual interest to any kitchen. With their classic rectangular shape and sleek, reflective finish, glass subway tiles make a simple yet stylish statement. While subway tile backsplashes are relatively easy DIY projects, proper planning and preparation are key to achieving a successful result. This step-by-step guide will walk you through everything you need to know to install a beautiful and functional glass subway tile backsplash in your kitchen.
Planning Your Glass Subway Tile Backsplash
Before you start tiling, there are some important factors to consider in your backsplash planning and preparation:
Choose Your Tile
Glass subway tiles come in a range of sizes, colors, finishes, and quality levels. Consider the overall look you want to achieve and choose tiles accordingly. Some things to consider:
- Tile size – The most common options are 3×6 inch or 4×8 inch. The elongated 4×8 size has a more contemporary look.
- Gloss level – Glass tiles come in gloss, satin, or frosted finishes. Gloss is very reflective, satin has a soft sheen, and frosted is matte.
- Color – From crisp whites to bold colors like blue and green, the options are endless. Neutrals work well for a clean look.
- Quality – Higher quality tiles have uniform sizing and thickness, as well as straighter edges. Check reviews and samples before purchasing.
- Accents – Consider using accent tiles sparingly to add interest. Subway tile shapes like circles or diamonds can be nice.
Calculate How Much Tile You Need
Measure the backsplash area thoroughly and use an online calculator to determine how many tiles you’ll need. Don’t forget to account for pattern matching and waste. It’s always better to overestimate.
Choose Your Grout
Grout fills the joints between tiles. Contrasting grout draws more attention. For a seamless look, choose grout that matches the tile color. Grout also comes in different materials like cement, epoxy, or silicone.
Gather the Right Tools
Installing subway tile backsplash requires some specialized tools. Be sure you have on hand:
- Tile cutter and plenty of replacement wheels
- Grout float
- Grout sealer
- Mixing bucket
- Notched trowel
- Tile spacers
- Level
- Hammer
- Rags
- Safety gear – gloves, goggles, knee pads
Prepare the Surface
The backsplash area must be clean and smooth. Remove any old backsplash material or wallpaper. Fill any holes or uneven spots with spackle. The surface should be wiped down and free of grease, dust, or soap residue which can prevent adhesion.
How to Install the Tile Backsplash
Once you’ve completed the planning phase, it’s time for the fun part – install the tile! Follow these steps for proper installation:
Step 1 – Mark Your Layout
Mark a horizontal line at the very bottom of where you want your backsplash to begin using a level and pencil. This keeps the rows straight and evenly spaced. It also gives you a guide to follow.
Then mark vertical lines at each end where the tiles will stop. This helps keep the edges straight.
Step 2 – Apply Thinset Mortar
Mix thinset mortar according to package directions to a toothpaste-like consistency. Apply it to the wall area using a notched trowel held at a 45° angle.
Step 3 – Place the Tiles
Starting at the bottom left marked line, press the first tile firmly into the thinset. Use spacers between each tile to keep consistent grout line spacing.
Work row by row from left to right, bottom to top. Periodically check levelness with your initial horizontal line as you go. Cut edge tiles as needed for a precise fit.
Step 4 – Let Tile Set
Allow thinset to cure for 24 hours without disturbing the tiles. Remove spacers and check for secure adhesion by gently twisting each tile. Re-adhere any loose tiles.
Step 5 – Grout the Tile
Mix grout per package instructions. Apply it over the tiles using a rubber grout float. Push it deeply into joints and spaces. Allow it to set slightly, then scrape off residue with damp rags.
Step 6 – Seal the Grout
Once grout has cured fully (48 hours), apply grout sealer according to product directions. This will protect grout from stains and moisture. Allow sealer to dry completely.
Step 7 – Caulk Perimeter with Silicone
Use silicone caulk to fill the gap between the top edge of the backsplash and the wall. This seals the joint between tile and wall. Wet finger and tool into a neat bead.
That’s it! Now you can enjoy your brand new, professionally finished glass subway tile backsplash!
Tips for a Successful Subway Tile Backsplash Project
Here are some helpful tips to ensure your project goes smoothly from start to finish:
- Carefully plan the tile layout if incorporating patterns or designs. Draw it out to scale on graph paper first.
- When cutting tiles, go slowly and steadily. Rushing increases cracking and chipping risks.
- Make sure backsplash area is clean and dry before applying any materials. Contaminants can ruin adhesion.
- Don’t spread more thinset than you can tile over within 10-15 minutes. It will dry too quickly.
- Check level and plumb often as you tile. Even small inconsistencies become noticeable.
- Remove all spacers before grouting – you don’t want them getting stuck in the joints.
- When grouting, work in small sections for easier clean up and to avoid drying too quickly.
- Use a grout release product to make cleaning excess grout off the tile surface easier.
- Don’t walk on newly tiled area for at least 24 hours to allow materials to fully cure and bond.
FAQs About Installing a Glass Subway Tile Backsplash
Here are answers to some frequently asked questions about installing glass subway tile backsplashes:
Do glass subway tiles need to be sealed?
No, glass tiles do not need a sealant. Their non-porous, waterproof surface already provides maximum protection. Using any sealant could create a hazy film.
What’s the best grout to use with glass subway tiles?
Cement-based sanded grout works well for most glass tile installations. Make sure to use a flexible formulation containing latex. Match the grout color to your tile for a seamless look.
How do I cut glass subway tiles?
Use a quality wet tile saw with a diamond blade. Cut slowly and steadily, allowing water to flow over the tile surface. Safety gear like glasses and gloves are a must.
Should I use spacers for subway tile backsplash?
Yes, plastic spacers are highly recommended. They ensure even grout line spacing for a consistent layout. Remove them before grouting.
What thinset mortar is best for glass subway tiles?
Use a high quality unmodified thinset mortar meeting ANSI A118.1 specifications. Do not use mastic adhesive – it doesn’t provide enough durability for a long lasting bond.
How long does thinset take to cure before grouting?
Allow 24 hours after installation for the thinset mortar to fully cure before applying grout. This ensures a strong bond.
Can I use sanded grout with glass subway tiles?
Yes, sanded grout can be used. It provides better performance for joints wider than 1/8 inch. Make sure to seal it well to avoid abrasion on the smooth tile.
