How to Apply Backsplash Tile

Installing a backsplash tile in your kitchen or bathroom can transform the look and feel of the space. A tile backsplash serves both form and function – protecting the walls from moisture damage while also providing an attractive, easy-to-clean surface. With some planning, patience, and basic DIY skills, you can achieve stunning results and save on installation costs by learning how to apply backsplash tile yourself. This comprehensive guide will walk you through the entire process step-by-step.

Getting Started with Your Backsplash Tile Project

Before you can start applying tiles, there are a few important steps to take for a successful installation. Proper planning and preparation will ensure your backsplash looks amazing and lasts for years to come.

Choose the Right Tile for the Space

With so many backsplash tile options to pick from – ceramic, porcelain, glass, stone – it’s essential to choose one suitable for the location. Consider the following:

  • Kitchen backsplashes – Look for moisture-resistant tiles like porcelain or ceramic that can withstand heat and stains. Glass tiles can work too but require extra sealing.
  • Bathroom backsplashes – Tile needs to stand up to frequent water exposure. Porcelain, ceramic, or natural stone are great bathroom tile options.
  • Style – Match the tile material, color, and design to your overall room decor. Sleek subway tiles or mosaics perfectly complement modern kitchens, while elaborate patterns like Moroccan fish scale tiles work for traditional spaces.
  • Budget – Backsplash tile pricing varies greatly. Set a budget and find tiles within that affordability range.
  • DIY Skills – Beginners may want to start with simple ceramic, porcelain or glass subway tiles which take less time and skill to install. Elaborate tiles require more tile-cutting and thin-set mortar work.

Calculate How Much Tile Is Needed

Measure the total surface area of the backsplash and purchase 10-15% extra to account for broken tiles, miscuts and uneven walls requiring additional tiling. Use a tile calculator or this formula:

Length of backsplash (inches) x Height (inches) = Total Square Inches

Total Square Inches ÷ Tile Size (Square Inches per tile) = Approximate Number of Tiles Needed

Don’t forget the grout! About 25% more grout than tiles is needed.

Gather the Necessary Materials

Installing backsplash tile requires specific tools and supplies. Ensure you have all of them ready before starting:

  • Tile adhesive (thinset mortar)
  • Notched trowel for spreading adhesive
  • Grout
  • Grout float for applying grout
  • Spacers for consistent tile spacing
  • Tile cutter for custom cuts
  • Wet saw for intricate tile shaping (optional)
  • Grout sealer
  • Tile sealer, if needed per tile type
  • Rubber grout float
  • Mixing buckets
  • Tile nippers
  • Safety gear – gloves, goggles, knee pads
  • Clean rags
  • Bucket for cleaning tiles
  • Tile leveling system (for large format tiles)
  • Painter’s tape

Prepare the Surface

The backsplash installation surface must be smooth, clean and dry for the tiles to adhere properly.

  • Remove existing backsplash if there is one
  • Eliminate any wall projections, old adhesive or grout
  • Fill any holes or imperfections with spackle
  • Sand rough areas
  • Clean and dry the surface thoroughly
  • Apply painter’s tape around the edges to protect the surrounding walls

Now the real tile installation work can begin!

How to Apply Backsplash Tile – Step-By-Step

Follow these key steps to properly install a backsplash tile area with professional results:

Step 1 – Plan the Tile Layout

Decide on the tile pattern and layout before starting to place any tiles. A basic straight or offset brick pattern is suitable for many backsplash designs. Here are some tips:

  • Draw the backsplash area on paper and experiment with tile arrangements.
  • Choose a layout that minimizes small cut tiles around the edges and window.
  • Mix tile packages during installation to disperse any color/pattern variations.
  • Align tiles so the grout lines are consistent.
  • Use level lines for tidy, professional results. Laser levels or a straight piece of wood can serve as guides.
  • For outlets, decide if tiles will fit fully or be cut around them.

Step 2 – Mix the Mortar

Combining the thinset adhesive powder with water to achieve the right consistency is key for optimal tile bonding:

  • Use the type of adhesive recommended for the tile material being installed.
  • Mix it to a thick but spreadable consistency per product instructions.
  • Only blend small batches that can be used within 2 hours. Discard any unused adhesive.
  • If the mix is too thin, the tiles won’t adhere properly. If it’s too thick, application will be difficult.
  • Let the mixture slake for about 10 minutes after blending, then remix before using.

Step 3 – Apply the Tile Adhesive

With the thinset mortar ready, it’s time to start spreading it onto the installation surface:

  • Use a notched trowel held at a 45-degree angle to scrape adhesive onto the wall in straight rows.
  • Apply only enough mortar that tiles can be set before it skins over – work in small sections.
  • Use the trowel notches to create ridges of even thickness and an optimal adhesive bed.
  • Back-butter tiles with adhesive for maximum adhesion, if needed.
  • Take care to keep adhesive off previously installed tiles. Immediately clean any messes.

Step 4 – Set the Tiles

Once the mortar is spread onto the wall, carefully set each tile into place:

  • Place tiles firmly into the adhesive bed, using spacers to maintain even grout line spacing.
  • Align tiles so edges line up cleanly and consistently. Use leveling tools if needed.
  • Work methodically and systematically row by row from the bottom up for the most controlled installation.
  • To avoid lippage issues between tiles, use a leveling system for large format tiles.
  • For intricate mosaics, pre-setting tiles face-up on a mesh sheet makes installation much easier.
  • Allow the adhesive to cure fully (usually 24-48 hours) before grouting or using the area.

Step 5 – Cut and Shape Border Tiles

The perimeter tiles require custom cutting to fit against walls and around outlets and fixtures. Here’s how to achieve those perfect cuts:

  • Mark tiles to the correct size and shape using a pencil or tile marker.
  • Score the tile face with a cutter tool, then snap it along the scored line.
  • For curved cuts, use tile nippers to nibble away small fragments until the shape is right.
  • A wet saw (tile saw) filled with water can make precision cuts and shaped tiles, including L-cuts and holes.
  • Rub the cut tile edges smooth with an abrasive stone. Apply sealer if needed.
  • Set custom cut tiles just like full ones, utilizing spacers to align grout lines.

Step 6 – Apply and Grout the Tiles

Grouting fills the joints between tiles, unifying them into one cohesive surface:

  • Mix grout powder with water or latex additive to a thick peanut butter consistency.
  • Use a rubber grout float or squeegee to press the grout into the tile joints firmly.
  • Hold the float at a 45-degree angle and scrape diagonally across tiles to fill joints.
  • Wait 10-15 minutes for the grout to firm up slightly in joints. Then polish the tiles clean with minimal water.
  • Apply a sealer to the grout once fully dried to lock in color and strengthen water resistance.
  • Follow all drying times recommended by the product manufacturer.

Step 7 – Seal and Finish the Tile

The final step is applying any needed protective sealers and caulk:

  • For grout joints where backsplash meets countertop, tub or sink, use a flexible silicone caulk.
  • If necessary for the tile material, apply a penetrating or surface sealer as an extra layer of protection.
  • Let caulk and sealers fully cure before using the backsplash.
  • Lastly, buff the tiles gently with a soft, dry cloth to reveal their full luster.

With proper care and maintenance, your stunning new backsplash tile will provide many years of beauty and function in your kitchen or bath.

Frequently Asked Questions about Applying Backsplash Tile

Still have questions about DIY tiling? Here are answers to some frequently asked queries:

How Long Does It Take to Install a Backsplash?

For an experienced DIYer, expect the installation process to take 2-3 days based on the backsplash size. Beginners should budget 5 days or more. Rushing raises the chance of mistakes.

What’s the Best Grout Color for Backsplash Tile?

Use grout that matches or blends in subtly with the tile color for a seamless look. Bright white grout can look harsh between dark tiles. Go for gray, ivory or tan instead.

How Is Backsplash Tile Installed Around Outlets?

Carefully measure and cut tiles to fit neatly around outlets. Remove the outlet covers first. Leave a tiny gap for grout rather than butting tiles against the box.

Should Backsplash Tile Go All the Way to Ceiling?

Full height backsplashes look bold and sleek. However, taking tile only 3/4 of the way up is common. Just make sure the bottom and top edges align properly.

What To Do with Backsplash Tile Edge Against Wall?

You can “scribe” the final tiles meaning shaving off the backside edge so the front maintains a straight grout line where needed. Or use caulk between the tile edge and wall.

Can You Install Backsplash Tile Over Existing Backsplash?

It’s possible but not ideal. Removing the old backsplash allows you to remedy any underlying problems and start fresh with the proper surface.
