Can I Use Silicone to Install Backsplash?

Installing a beautiful backsplash in your kitchen or bathroom can really transform the look and feel of the space. Backsplashes not only look great, but they also serve the practical purpose of protecting your walls from water damage and stains. When it comes to installation, using the right materials is key for getting a long-lasting, high-quality result. One common question that comes up is whether silicone adhesive can be used to install backsplash tiles. Below we’ll go over the pros and cons of using silicone and give recommendations for best practices when installing a backsplash.

What is Silicone?

Silicone is a flexible, waterproof sealant that comes in squeeze tubes or caulking cartridges. It is a type of polymer made up of silicon, oxygen, and other elements that cures into a rubber-like solid when exposed to moisture in the air.

Some key properties and uses of silicone include:

  • Flexible – It can expand and contract with building materials as they shift due to temperature changes. This flexibility prevents cracks from forming.
  • Waterproof – Silicone has excellent water repellency, making it ideal for wet environments like bathrooms and kitchens. It creates a watertight seal.
  • Adheres well – Silicone bonds reliably to many common construction materials such as metal, plastic, glass, and tile.
  • Heat resistant – It can withstand high temperatures up to more than 500°F (260°C), so it can be used around stoves, ovens, and other cooking appliances.
  • Sealing and caulking – Silicone is commonly used to seal joints and gaps around sinks, tubs, showers, backsplashes, countertops and more. Its flexibility allows for joint movement.

So in summary, silicone has properties that make it suitable for waterproofing and adhering tile in kitchen and bathroom environments. It remains flexible over time and can withstand heat.

Can Silicone Be Used to Install a Backsplash?

Silicone can be used to install backsplash tile, but there are some important caveats. Here are the pros and cons of using silicone adhesive for backsplash installation:

Pros of Silicone for Backsplash Installation

  • Flexibility – Silicone allows for small movements in the backsplash which helps prevent grout cracking and tile popping off. This is beneficial for materials like glass tile that may expand and contract.
  • Waterproofing – Silicone provides a waterproof seal between the backsplash tiles and the wall, preventing moisture damage.
  • Ease of use – Silicone sealant is easy to apply from a squeeze tube. No mixing or preparation is required.

Cons of Silicone for Backsplash Installation:

  • Not ideal for heavy tiles – Silicone alone may not be strong enough to support heavier porcelain, ceramic, or stone tiles. These heavier tiles are more prone to slipping over time.
  • Difficult to remove – Silicone is extremely hard to remove once cured. This can make it difficult to replace any damaged tiles later on.
  • Gives less finished look – The silicone beads between tiles are visible. This gives the backsplash a less polished, finished look compared to grouted tile.
  • Not for shower walls – Silicone should only be used for backsplashes, not full shower walls. Building codes often require mortar for shower tile installation.

So while silicone has its benefits in certain backsplash situations, it also has some distinct disadvantages that limit its use for many tile installations.

Best Practices for Using Silicone to Install Backsplash

If you do opt to use silicone sealant for your backsplash project, here are some tips to get the best possible result:

  • Only use 100% silicone, not silicone-modified acrylics or latex sealants which are less reliable.
  • Thoroughly clean and prep the wall surface before applying silicone. Remove any grease, grime, or soap residues.
  • Apply a primer/sealer first if painting over silicone. Unprimed silicone will not accept paint well.
  • Ensure at least 2-3 mm gaps between tiles to allow for silicone application and expansion.
  • Apply silicone in a continuous bead using a caulking gun, ensuring no gaps are left.
  • Use painter’s tape along the edges for easier clean up and straight silicone lines. Remove tape before the silicone skins over.
  • Let the silicone fully cure (typically 24-48 hours) before exposing it to moisture.

Even when following best practices, keep in mind that silicone will likely not last as long as traditional mortared tile, and repairs may be difficult. Weigh the pros and cons carefully before using silicone adhesive for your backsplash installation.

Recommended Alternatives to Silicone for Backsplash Installation

For most backsplash projects, we recommend using a more robust installation method over silicone adhesive:

Tile Mortar

Mortar provides a much stronger, long-lasting bond than silicone. It also allows for easy replacement of any damaged tiles. We recommend mortar for heavier tile materials like ceramic, porcelain, or stone. Use a notched trowel to spread a thin, even layer on the wall, then firmly press tiles into place.


Grout fills the joints between tiles with a cement-based material. This protects the underlying wall, prevents moisture intrusion, and gives a polished finished look. After tile has been set with mortar, grout is pressed into the joints and wiped clean. White grout is common with most backsplashes.

Mastic Adhesive

Mastic is an adhesive specifically designed for tile. Similar to silicone, it remains somewhat flexible. Fibered mastic adds fiber material for extra strength and stability. Mastic works well for many lightweight backsplash materials like glass, aluminum and plastic tiles.

Double-Sided Wall Tape

For ultra lightweight materials like laminate panels, stainless steel, or peel-and-stick mosaic, double-sided acrylic foam tape offers a fast, simple installation. Clean the wall thoroughly, press the tape onto the back of the panels, peel off the outer facing, and stick to the wall.

So in summary, while silicone may work in certain backsplash situations, we typically recommend mortar, grout, tile adhesives, or double-sided tape for a more secure and permanent installation result. Always check the tile manufacturer’s recommendations for the best installation method for your specific tile material.

How to Use Silicone Along with Mortar for Backsplash Installation

If you want the additional flexibility and waterproofing of silicone along with the strength of mortar, it is possible to use both adhesive methods together:

  1. Spread thinset mortar using a notched trowel and firmly press tiles into place.
  2. Let mortar fully cure according to directions, typically 24-48 hours.
  3. Mix grout according to package instructions and apply to tile joints, ensuring full coverage.
  4. Let grout cure fully, then buff and seal grout lines.
  5. Apply a bead of silicone sealant along all joint lines and the perimeter edge using a caulking gun. Tool the silicone for a smooth finish.
  6. Wipe away any excess silicone with a damp cloth before curing begins.
  7. Allow 24 hours for silicone to fully cure before exposing to moisture.

This combines the strength and advantages of mortar and grout with the added flexibility and waterproofing of silicone. The silicone essentially acts as a sealant to fortify problematic areas or provide extra leakage protection.

Using silicone in addition to (not in place of) mortar and grout in this way can give you great results. Just be aware that if any repairs are needed later, the silicone can make tile removal more challenging.

FAQs about Using Silicone for Backsplash Installation

Here are answers to some frequently asked questions about using silicone adhesive for backsplash tile:

Can I use silicone to install backsplash over drywall?

Yes, silicone can be used to adhere lightweight backsplash tiles to drywall. Ensure the drywall is primed and painted first for proper adhesion. Silicone provides a waterproof seal to prevent moisture damage to the drywall over time.

What about using silicone on cement board backer?

Cement board provides an excellent surface for mortared tile. But silicone can still be used for additional flexibility and waterproofing, in combination with mortar and grout as outlined above.

Is silicone okay for glass backsplash tile?

Silicone is a good option for glass backsplash. The silicone allows the glass to flex naturally and prevents cracked grout joints. Ensure at least 2-3mm spacing between glass tiles. Clean thoroughly and use 100% silicone for best results.

Can I just use silicone instead of grout for backsplash?

It’s not recommended. Silicone alone often does not provide a polished finished look, can stain over time, and is difficult to keep clean. Grout still provides major advantages for appearance and performance. Use silicone only in addition to properly grouted tile.

How long does silicone last on a backsplash?

With proper prep and application, 100% silicone will typically last at least 10-15 years on a backsplash installation. Ensure you use the manufacturer specified cure time before exposing it to moisture. Proper maintenance helps extend the silicone’s lifespan.


Installing a beautiful, functional backsplash can really take your kitchen or bathroom to the next level. While silicone sealant has some advantages, traditional installation with mortar, tile adhesive, and grout provides the most secure, lasting result for most backsplash projects.

Carefully consider the pros and cons before deciding if silicone is suitable for your particular backsplash design and tile type. If using silicone, be sure to prep properly and use 100% silicone sealant. Combining silicone with mortar and grout can give you added flexibility and waterproofing along with a robust tile installation.

With attention to detail during installation and proper ongoing maintenance, you can enjoy your new backsplash for many years to come. Just take care to choose quality installation materials suited to your specific tile type and application. If ever in doubt, consult a professional tile setter for their recommendations. And remember – putting in the extra effort during installation will pay off for decades down the road with a backsplash you can be proud of.

Designing an Eye-Catching Backsplash Layout

You’ve selected the perfect tile or panels for your backsplash. Now comes the fun part – deciding on the layout design! Follow these tips for an attractive backsplash configuration:

Select a Focal Point

Every great backsplash has one area that grabs your attention. This could be behind the stove, over the kitchen sink, or a single section covered in an accent material.

Use Patterns and Textures

Consider elevating your backsplash with patterns like chevron, herringbone or subway tile layouts. Textured materials like stone, brick, or pebbled tile add visual interest.

Incorporate Accent Tiles

Work in tiles of a contrasting color, interesting shape or unique material like glass or metal to draw the eye. Limit accent tiles to 15-20% of the area for best results.

Vary Orientation

Mixing up the direction of rectangular tiles, or using shaped tiles like hexagons, creates depth. Horizontal, vertical, and diagonal tile orientations prevent monotony.

Combine Materials

Using two or more complementary materials can add layers to the design. For example, pair metal and glass tile, or ceramic tile with a stone or wood accent strip.

Include Borders

Frames your backsplash with borders along the edges and as dividers between sections to make the design more polished
