Installing tile over an existing laminate backsplash can completely transform the look and feel of your kitchen. With the right preparation and materials, tiling over laminate is a straightforward DIY project that allows you to upgrade your backsplash on a budget. This comprehensive guide will walk you through each step of the process to ensure your new tile backsplash looks beautiful and lasts for years to come.
Materials Needed to Tile Over Laminate Backsplash
Before starting any tiling project, it’s important to have all the necessary materials on hand. Tiling over laminate requires just a few specialty tools and materials beyond the tile itself:
- Tile adhesive: Choose a premium lightweight polymer modified thinset mortar designed for walls and backsplashes. This specialized adhesive will form a strong, water-resistant bond between the laminate and tile.
- Grout: Pick an unsanded grout in a color that complements your tile. Unsanded grout is optimal for grout joints 1/8 inch or smaller.
- Trowel: Use a notched trowel specifically made for backsplashes to spread the adhesive. A 1/4″ x 3/16” v-notched trowel works well.
- Tape measure and spacers: Measure carefully and use tile spacers to get straight, evenly spaced grout lines.
- Tile cutter: Cut ceramic or porcelain tiles to fit around outlets and other obstacles.
- Grout float and sponge: Use these tools to spread and wipe away excess grout.
Pick high-quality tile that will stand up to heat, moisture, and everyday wear and tear in the kitchen. Ceramic, porcelain, or natural stone tiles are good options. Measure the backsplash area thoroughly so you know exactly how many tiles are required.
Prepping the Laminate for Tile
Preparing the existing laminate backsplash is one of the most important steps in achieving a successful end result. Taking the time to properly prep will allow the tile adhesive to bond tightly.
Cleaning
First, clean the entire surface with a grease-cutting degreaser and rinse thoroughly. This eliminates any dirt, debris, or oils that could interfere with adhesion.
Sanding
Lightly sand the laminate using 100-150 grit sandpaper. This roughens up the smooth surface so the adhesive can grip better. Be careful not to sand too aggressively and damage the integrity of the laminate.
Applying Primer
Sweep away all dust after sanding, then apply a coat of primer formulated for laminate surfaces. The primer gives the thinset an additional surface to cling to for maximum hold.
Checking for Moisture
Since laminate itself is not waterproof, it’s important to check for any moisture issues behind the laminate before tiling. Look for dark spots or areas of swelling and test with a moisture meter if needed. Address any moisture problems before moving forward.
With the laminate prepped, you can begin applying the tile.
How to Apply Tile Adhesive Over Laminate
Spreading the thinset adhesive properly is the foundation of a long-lasting tile backsplash. Follow these tips for success:
- Apply a thin, even layer of adhesive using the notched trowel. Cover just one small section of laminate at a time to prevent the thinset from drying out.
- Use the flat side of the trowel to first “butter” the back of each tile. Then set tiles firmly in place, twisting slightly, to embed them in the thinset.
- Check tiles periodically to ensure at least 80-90% coverage on the back of each tile.
- Use tile spacers between each tile to get straight, evenly spaced grout lines.
- Scrape away excess thinset squeezed up between tiles with putty knife or trowel edge.
- Allow tiles to set for 24 hours before grouting. Do not disturb or walk on them as they cure.
Applying the adhesive properly takes some finesse. Follow the product directions closely and work in small sections for best results.
Grouting Tile Over Laminate
Once the tile adhesive has fully cured, it’s time to grout. Follow these tips for professional-looking finished grout lines:
Applying the Grout
- Work in small sections, wiping away excess grout before it dries.
- Use the grout float to force grout into the seams between tiles. Hold the float at a 90° angle and use a swirling motion.
- Add more grout and repeat until all joints are completely filled.
Cleaning Up
- Allow grout to cure for 5-10 minutes until semi-firm. Use as little water as possible when cleaning.
- Hold sponge flat against tile and wipe diagonally across joints to prevent pulling grout out.
- Rinse sponge frequently and change rinse water often.
- Check for haze and missed spots. Re-wipe with damp sponge when needed.
- Let grout dry fully before using backsplash. Avoid water and cleaning for 48-72 hours.
With some careful grouting technique, you can get flawless finished grout lines on your new backsplash.
Tiling Laminate Backsplash Do’s and Don’ts
Follow these do’s and don’ts to ensure success tiling over laminate:
Do:
- Clean and sand the laminate before priming and tiling.
- Use a high-quality polymer modified thinset mortar designed specifically for walls.
- Apply primer to the sanded laminate before applying thinset.
- Allow thinset adhesive to cure fully (24 hours) before grouting.
- Seal grout with a penetrating sealer to protect from stains.
Don’t:
- Tile over laminate in a high-moisture area like directly behind a sink.
- Use a standard multipurpose or mastic adhesive. Stick to specially formulated thinset.
- Spread more thinset than you can tile over in 30 minutes. It may dry out.
- Grout until tile adhesive has cured for a full 24 hours.
- Neglect to seal grout lines. Unsealed grout will stain easily.
Following these guidelines carefully will lead to success on your laminate backsplash tiling project.
Tips for Cutting Tile Around Obstacles
One tricky part of any tile installation is accurately cutting tiles to fit around outlets, pipes, corners, and other obstacles. Here are some tips for making careful tile cuts:
- Mark the area needing cut with a pencil line for reference. Double check your measurements.
- Set tile to be cut in place next to last full tile and align against a spacer. Mark along edge.
- Clamp a straightedge like a yardstick to the tile as a cutting guide if needed.
- Score the tile by tracing the marked line several times with the tile cutter wheel.
- Snap the tile downward over the tile cutter bar for a clean break along the score line.
- Use a rubbing stone or sandpaper to smooth rough edges on cut tiles.
- Dry fit the cut tile pieces and continue to adjust until you achieve a perfect fit.
With some practice and good measurement techniques, you can master the art of cutting tile for a professional look.
Troubleshooting Problems Tiling Over Laminate
Even if you follow all the preparation steps and tiling best practices, you may run into a few issues with your laminate backsplash tile project. Here are some common problems and how to fix them:
Tiles loose or falling off: This usually means the thinset did not adhere properly to the laminate. Ensure the laminate is sanded, primed, and the thinset covers 80-90% of the tile back.
Cracked, broken tiles: Tiles may crack if you walk on them or grout too soon. Allow 24 hours for thinset curing before grouting. Use knee pads to avoid walking on newly tiled area.
Uneven grout lines: Check that tiles are level and use spacers. The laminate itself must be in good condition without warps or damage.
Discolored grout: Apply grout sealer to prevent staining. If already discolored, try cleaning with an oxygen bleach cleaner. May require re-grouting affected areas.
Moisture under tiles: Stop and address any moisture issues behind the laminate immediately. Remove affected tile and resolve before proceeding.
With proper thinset application and grouting technique, you can minimize issues tiling over laminate. Promptly addressing any problems that do appear will give you a stunning, long-lasting backsplash.
