Which Sealer Do I Use for My Application?

Food Safe vs Non Food Safe Concrete Sealers

When choosing a concrete surface for your home or business, the finish matters just as much as the design. One of the most common questions we hear at Newbold Stone is:

Which sealer should I use for my application?

The answer depends on how the surface will be used. Some applications need a food safe sealer, while others perform best with a durable non food safe coating designed for heavy wear or moisture exposure. Choosing the right sealer matters because it impacts safety, stain resistance, longevity, and how well the surface holds up in everyday use.

What Is a Concrete Sealer?

A sealer is the protective top layer applied to concrete surfaces after fabrication. It helps protect against:

• Stains
• Moisture penetration
• Scratches and wear
• UV fading
• Daily use damage

The right sealer can extend the life of your custom concrete while keeping it looking clean and polished.

When You Need a Food Safe Sealer

Food safe sealers are ideal for surfaces where food prep or direct food contact may happen.

Best applications include:

• Kitchen countertops
• Outdoor kitchens
• Bars and serving areas
• Restaurant counters
• Dining surfaces

These sealers are formulated to be safe once fully cured and are commonly selected for homes and commercial spaces where hygiene and safety matter.

If you plan to prepare vegetables, place food directly on the surface, or use the area regularly for serving, food safe is the right move.

When a Non-Food Safe Sealer Makes Sense

Some applications do not require direct food contact, so performance and durability may be the bigger priority.

Best applications include:

• Bathroom vanities
• Fireplace surrounds
• Accent walls
• Furniture tops
• Decorative concrete pieces
• Commercial reception desks

These sealers may offer stronger chemical resistance, a different sheen level, or enhanced durability depending on the environment.

Other Factors to Consider

Beyond food contact, the right sealer also depends on:

Indoor vs Outdoor Use

Outdoor surfaces need protection from sun, moisture, and temperature swings.

Matte vs Gloss Finish

Some sealers give a natural matte look while others create a richer polished sheen.

Maintenance Expectations

Some systems require occasional reapplication, while others are built for long-term performance.

Residential vs Commercial Traffic

Busy commercial spaces often need stronger protection than a low-use residential area.

Our Recommendation

Every project is different. A kitchen island has different needs than a bathroom vanity. A restaurant bar has different demands than a fireplace mantel. That is why Newbold Stone helps clients choose the right sealer based on how the piece will actually be used, not just how it looks on day one.

Need Help Choosing the Right Sealer?

Choosing the right sealer is just as important as choosing the concrete itself, and making the wrong call can impact appearance, maintenance, and long-term performance. At Newbold Stone, helping clients select the proper finish is part of the process, not an afterthought.
