Do You Grout Between Backsplash and Countertop?

Installing a backsplash is one of the best ways to add visual interest and protect the walls behind a kitchen countertop. But one decision that often comes up is whether to grout between the backsplash and countertop. Here’s what you need to know about grouting this joint.

What is Grouting?

Grout is a cement-based material used to fill in the joints between tiles. It creates a waterproof seal that prevents moisture from seeping behind the tiles. Grout also locks the tiles together for a more stable surface.

When installing a backsplash, grout is typically applied between each tile and along the perimeter edges. But the decision of whether to grout between the backsplash and countertop is not always straightforward.

Should You Grout Between Backsplash and Countertop?

Whether you should grout between the backsplash and countertop depends on a few factors:

Aesthetics

Some homeowners prefer the straight, clean line created by not grouting this joint. The countertop forms a distinct border at the bottom of the backsplash.

Skipping the grout line here can make the transition between backsplash and countertop more seamless. The materials appear as one continuous surface.

Countertop Material

What material your countertop is made of is one of the biggest considerations. Grout works well with ceramic tile, stone, or porcelain backsplashes. But with some materials, the grout line could create an undesirable appearance.

For example, grout between a glass backsplash and solid surface countertop may look disjointed. The countertop material often dictates whether grouting this joint will have the best visual effect.

Water Protection

One of the main reasons to grout is to seal surfaces from moisture damage. The kitchen backsplash is often prone to splashes, spills, and debris.

Grouting provides crucial waterproofing where the backsplash meets the countertop. This prevents liquid from dripping down behind the backsplash and damaging the walls.

If you’re concerned about water penetration, it’s a good idea to grout between surfaces.

Movement Prevention

On its own, the backsplash tile may have some natural movement or vibration. Heavy use in the kitchen can cause subtle shifting.

Grouting between the backsplash and countertop helps anchor the tile. This prevents cracks, loosening, and other movement issues over time.

Cleanliness

Without grout, the joint between the backsplash and countertop can trap food particles, grease, and other grime. This small space often becomes an unsightly collection point.

Filling it with grout creates a flush surface that’s easier to wipe down. Grout also resists staining better than an open joint.

Best Practices for Grouting

If you decide to grout between the backsplash and countertop, here are some tips to get the best results:

  • Allow a small 1/8 inch gap between the materials. Don’t grout flush to the countertop. This allows room for natural movement and prevents cracking.
  • Use a grout float to force grout into the gap. Make sure there are no voids.
  • Apply caulk, not grout, where the countertop meets sinks or appliances. Caulk offers more flexibility.
  • Choose an unsanded grout for joints 1/8 inch or smaller. Sanded grout can scratch certain surfaces.
  • Seal the grout once dry to protect from stains. Apply a grout sealer annually.
  • When cleaning, use a soft sponge and mild cleaner. Avoid abrasives.

Grout Color Considerations

If grouting between the backsplash and countertop, choose a grout color that complements both materials. Here are some tips:

  • Match the grout color to the tile for a monochromatic look.
  • Choose a darker grout for light stone backsplashes to define the tile edges.
  • Use bright white grout for dramatic contrast against darker tiles like slate or granite.
  • Select a neutral mid-tone grout for a more subtle effect.
  • Consider a clear grout for glass tile backsplashes to highlight the tile itself.

Alternatives to Grouting

Some alternative options if you prefer not to grout between the backsplash and countertop include:

  • Caulk: Caulk offers flexibility and can resist water. Make sure it’s 100% silicone.
  • Metal trim: Brushed nickel, copper, or other metal trim can cover the joint attractively.
  • Wood trim: Stained wood adds a rustic accent between surfaces. Use a water-resistant variety.

Conclusion

Deciding whether to grout between the backsplash and countertop comes down to the specific materials used, your aesthetic tastes, and water protection needs. Following best practices for prep and application will lead to long-lasting, high-quality results. And explore creative alternatives like trim if skipping the grout altogether. With some careful planning, you can make the perfect design decision for your kitchen.

Frequently Asked Questions

Should you caulk or grout between backsplash and countertop?

Either caulk or grout will work, but they each have different properties. Grout provides a waterproof joint, but caulk offers more flexibility. Use 100% silicone caulk if you want to allow independent movement between the surfaces.

What color grout should I use between backsplash and countertop?

Choose a grout color that matches or complements the backsplash tile. Darker grout works well with light stone tile. Bright white grout contrasts nicely with bold or dark tile. Or select a neutral, mid-tone grout color.

How big should the gap be between backsplash and countertop?

Leave a small 1/8 inch gap between the backsplash and countertop when installing. This gap allows room for any subtle shifting and prevents cracking of grout or tile.

Can you use sanded grout between backsplash and countertop?

For joints less than 1/8 inch, use unsanded grout. The fine sand particles in sanded grout can scratch certain surfaces like natural stone. Unsanded grout results in a smoother finish.

Should you seal grout between backsplash and countertop?

Yes, it’s highly recommended to apply a penetrating grout sealer once the grout has fully cured. This protects the grout from moisture damage and stains. Reapply the sealer periodically for ongoing protection.
