Tile Selection

• A backsplash can make a huge difference in the personality of a kitchen. Use bold or bright colors to lighten up a drab space. Alternate plain colored tiles with picture tiles to create a wall that tells a story. Choose stone, slate or tumbled marble tiles to add depth and dimension. Mix and match tiles of different textures and colors to create a tile design that is truly unique. Choose border tiles that complement your overall design. Practice creating different patterns with the tiles until you find one you like. You can also select a pattern from a tile how-to book.
  
  

Preparation

• Start with clean walls that are totally free of grease and dirt. Remove all old tile and debris. Patch any holes with a drywall repair kit. Remove switch plates and cover openings with painter's tape. Cover the countertop with a plastic drop cloth.
  
  You can use a cementitious backerboard or you can attach the tiles directly to the wall. If attaching directly to the wall, lightly sand the area first. Use tile mastic instead of tile-setting mortar. The mastic does not require mixing and forms a stronger bond.
  
  

Application

• Draw a perfectly vertical line in the center of the area you will cover. This is where you will begin securing the tiles to the wall. With a V-notched trowel, use long sweeping motions to apply the mastic to the wall. Hold the trowel at a slight angle. You want to cover an area large enough to accommodate 6 to 8 tiles. Check to see if there are any bare spots. Begin pressing the tiles onto the wall surface on both sides of the vertical line, starting with the bottom row first. Use spacers to standardize the space between tiles. Continue applying mastic and tiles until your backsplash is complete. Make sure you set the tiles according to your decorative pattern. Use a tile cutting tool for pieces that need to be trimmed or notched.
  
  Allow the backsplash to dry overnight before applying the grout. Use unsanded grout for gaps between the tiles less than 1/8". For wide gaps, use sanded grout. Apply grout according to the manufacturer's directions. Use caulk to put the finishing touches on your masterpiece between the first row of tile and the counter surface.
  
  

Practice Makes Perfect

• If you're nervous about the project outcome, take a few lessons before you start. Most home improvement stores offer classes on using tile and grout. Alternatively, you can practice on a piece of plywood, using less expensive or scrap pieces of tile.
