Does Marble Backsplash Need To Be Sealed?

Marble is a popular choice for kitchen and bathroom backsplashes because of its timeless beauty and elegance. However, many homeowners wonder if they need to apply a sealer to marble backsplash tiles to protect them. Understanding whether sealing is necessary, what sealers do, and how to seal marble can help you make the best decisions for your backsplash installation and upkeep.

What Is A Marble Sealer?

A marble sealer is a liquid protective coating that is applied to the surface of natural stone tiles like marble. Sealers work by bonding with the pores in the stone to create a barrier that prevents stains from penetrating into the stone.

There are two main types of marble sealers:

Impregnating Sealers

  • Soak into the stone pores without leaving a coating on the surface
  • Provide invisible protection below the surface
  • Allow stone to breathe and don’t change natural appearance
  • Protect against stains

Topical Sealers

  • Form a protective coating on the stone surface
  • Enhance shine and glossiness of the marble
  • Repel water, oil, and stains on the surface
  • Require more frequent reapplication than impregnating sealers

Both offer protective benefits, but impregnating sealers are more commonly used for backsplashes.

Do You Need To Seal Marble Backsplash?

Sealing a marble backsplash is a smart preventative measure, but not strictly necessary. Here are some factors to consider when deciding whether to seal:

Stone Variety

  • Carrara and Calacatta marble are more porous than other marble types. Their higher porosity makes them more prone to staining and etching. Sealing these varieties is highly recommended.
  • Denser marbles like Emperador are less permeable and don’t necessarily require sealing.

Backsplash Location

  • Backsplashes in kitchens or bathrooms with frequent exposure to water, oils, and acids benefit more from sealing.
  • Low-use backsplashes in formal dining rooms or powder baths have less need for sealing.

Desired Appearance

  • If you want to enrich the color and make the marble glossier, a topical sealer can help achieve that enhanced sheen.
  • If you simply want to maintain the natural matte finish of honed marble, an impregnating sealer would be a better match.

Upkeep Preference

  • Sealers help minimize maintenance and make stains easier to clean. If easy upkeep is important to you, sealing is a wise idea.
  • If you don’t mind putting in more regular maintenance work, sealing is less critical.

While sealing may not be an absolute necessity, it offers inexpensive protection to enhance longevity and appearance. Consulting a stone installation professional can also provide recommendations based on your specific backsplash marble and design.

What Are The Benefits Of Sealing Marble Backsplash?

Sealing your marble backsplash tiles provides a range of helpful protective benefits:

Stain Resistance

  • Sealers prevent stains from oil, grease, food, drinks, soap scum, and other kitchen and bathroom residues from setting into the stone.
  • Treated stone repels stains so they occur less often and are easier to wipe away.

Etch Mark Prevention

  • Marble is prone to etching from acidic substances like wine, juice, vinegar, etc. Sealers provide a barrier to help resist etching and corrosion.

Easier Cleaning

  • Sealing minimizes the amount of dirt, grime, and stains that can penetrate the marble. Less buildup in the stone means easier daily upkeep.

Enhanced Shine

  • Topical sealers add a glossy sheen and wet look to bring out the marble’s inherent veining and colors.

Moisture Resistance

  • Sealers protect marble against water exposure and mitigate moisture damage like mildew growth.

Investing in sealing your backsplash keeps your marble tiles looking their best for longer with less required maintenance.

What Should You Know Before Sealing Marble?

Before applying a sealer to your backsplash, keep these tips in mind:

Clean Thoroughly First

Any dirt, soap residue, oils, etc. should be cleaned from the marble before sealing. Leftover buildup can block the sealer from properly bonding.

Read Product Instructions

Different sealers require specific application and drying times. Read instructions carefully to ensure correct usage.

Consider a Sample Test

Try sealing a single backsplash tile first to confirm the sealer provides the desired look and protection.

Work in Sections

Seal smaller sections of backsplash at a time so the product doesn’t dry before you wipe off any excess.

Use Precautions

Proper ventilation, gloves, and goggles are important when working with sealers.

Add Additional Coats

For optimal protection, applying two coats of sealer is typically recommended.

Thorough planning helps ensure the sealing process improves the backsplash without any unwanted issues.

How To Seal A Marble Backsplash

Sealing a marble backsplash involves carefully preparing the surface and applying the sealer correctly. Follow these step-by-step instructions:

Supplies Needed

  • Marble impregnating or topical sealer
  • Clean microfiber cloths
  • Gloves
  • Eye protection
  • Ventilation fan
  • Paintbrush or applicator pad

Step 1: Clean the Surface

Use a pH-neutral cleaner and warm water to wash the marble backsplash tiles. Rinse thoroughly and allow to fully dry.

Step 4: Apply the First Coat

Use a clean paintbrush or applicator pad to apply an even layer of sealer over the marble. Cover small sections at a time.

Step 5: Allow to Penetrate

Let the first application sit for 15-20 minutes so it can soak in fully. Gently wipe any pools or drips.

Step 6: Wipe Away Excess

Use a dry microfiber cloth to thoroughly buff off any remaining sealer residue from the surface.

Step 7: Allow to Cure

Let the first coat cure for the time specified on the product instructions before adding a second coat.

Step 8: Apply Second Coat

Repeat steps 4-6 to add a second protective layer of sealer to the marble backsplash.

Step 9: Remove Masking

Once fully cured, remove all plastic sheeting and painter’s tape.

Step 10: Admire Results

Your sealed marble backsplash is now protected with an enhanced stain-resistant surface and lustrous glow.

Be sure to reseal the backsplash at least once a year moving forward. Proper sealing keeps natural stone backsplash looking like new!

Frequently Asked Questions About Sealing Marble Backsplashes

What types of sealers work best for marble backsplash?

Impregnating sealers that soak below the surface without altering appearance are ideal. Topical options like epoxies can also be used but may darken or add gloss.

How can you tell if marble backsplash needs resealing?

If spills and stains start soaking in rather than wiping away easily, it likely indicates the sealer is wearing off and due for renewal.

Will sealing prevent etching on marble?

Sealers help minimize etching but don’t provide full acid protection. Take care to promptly wipe acidic spills to limit potential etching damage.

Can you use a marble sealer in a bathroom?

Yes, marble sealers are safe for use in bathrooms. Make sure the product is designed for wet areas and provides mold/mildew resistance.

Is it better to seal marble before or after installation?

Sealing prior to installation helps protect from staining during the installation process. But you’ll still need to reseal once installed.

How long does sealer last on marble backsplash?

Sealer durability often ranges 12-18 months. Higher quality sealers may last 2-5 years. Reapply annually for best ongoing results.

Will sealer make marble backsplash shinier?

Topical sealers enhance shine, while impregnating options maintain natural stone appearance. Test products to ensure it provides the luster you desire.

Protecting the beauty and longevity of a marble backsplash is easy with proper sealing. Evaluate your specific backsplash situation to determine if sealing is right for you. When in doubt, consult a tile installation specialist for product recommendations. Investing a small amount of time and money into sealing can maintain your backsplash’s stunning appearance for many years of enjoyment.

Conclusion
