What is a Penny Floor? (5 Reasons to Love This Unique DIY)

Introduction: Why I Fell in Love with Penny Floors and Eco-Friendly Living

You know how I’m always looking for ways to make my home more eco-friendly without losing style? A few years ago, I discovered something that totally changed my approach to DIY flooring—penny floors. These floors aren’t just a quirky novelty; they’re a creative, sustainable way to reuse materials while adding a unique charm to your home. Honestly, it felt refreshing to find a project that was both good for the planet and deeply satisfying to make.

When I first heard about penny floors, I was skeptical. How could pennies glued to a floor really hold up over time? But after researching and trying it myself, I realized there’s a lot more to this technique than meets the eye.

If you’re someone who enjoys hands-on projects and cares about reducing waste while making your home stand out, penny floors might be exactly what you’re looking for. I want to share with you what a penny floor really is, why it’s special, and why I think it’s worth considering for your next home project.

What Is a Penny Floor?

Let’s start with the basics: What exactly is a penny floor?

A penny floor is a surface covered entirely with pennies arranged in a pattern or design and sealed with a clear epoxy resin or similar finish. The result looks like a shimmering mosaic of copper coins creating a smooth, glossy floor.

But this isn’t just about aesthetics. It’s about craftsmanship, recycling, and making something functional out of everyday objects that would otherwise be overlooked.

The History and Origin of Penny Floors

The idea of using pennies as flooring materials started gaining traction in the early 2000s as part of a larger DIY trend focused on creative reuse. People began experimenting with coins as decorative elements on countertops, backsplashes, and floors. Over time, the penny floor became recognized as a legitimate flooring alternative for those wanting something original and sustainable.

What makes penny floors stand out is how they combine old-world charm with modern materials science. By sealing pennies with epoxy, you create a surface that’s both beautiful and tough enough to handle foot traffic.

Materials Involved in Penny Flooring

To make a penny floor, you need:

  • Pennies: The stars of the show. Since 1982, US pennies are mostly zinc coated with copper plating, but older pennies are solid copper.
  • Adhesive: A strong glue or construction adhesive to stick pennies to the subfloor.
  • Epoxy resin: A clear coating that seals and protects the floor.
  • Subfloor: Usually plywood or concrete, cleaned and prepped.

Dimensions and Coverage

A standard penny is about 0.75 inches (19 mm) in diameter. To cover one square foot, you’ll need roughly 400-500 pennies depending on spacing.

For example:

  • A 100 sq ft room requires about 40,000-50,000 pennies.
  • That’s a lot of coins but collecting over time or buying in bulk can make it manageable.

How It’s Installed

The process involves:

  1. Subfloor Preparation: Clean, smooth surface free from dust or grease.
  2. Laying Out Pennies: Arranged tightly together covering the entire area.
  3. Gluing Pennies: Using adhesive to secure each penny in place.
  4. Applying Epoxy: Several coats of resin poured over the surface to embed coins fully.
  5. Curing: Allowing epoxy to harden and form a durable finish.

With patience and care, the result is a floor that looks like copper tiles but is far more affordable and unique.

Why I Chose Penny Flooring: 5 Reasons to Love This Unique DIY

I want to share the reasons I fell for penny flooring after trying it myself. These insights come from my own experience combined with research and feedback from others.

1. It’s an Eco-Friendly Way to Reuse Materials

How often do we think about the waste created by traditional flooring? Hardwood requires logging; tiles need mining clay and firing; vinyl is plastic-based with environmental costs.

Penny floors offer an alternative by repurposing existing coins—often ones no longer in circulation or damaged—and turning them into artful flooring.

Here’s what I learned:

  • The U.S. Mint produces about 8 billion pennies annually.
  • Many of these coins become obsolete or damaged and are taken out of circulation.
  • Mining copper for new materials has significant environmental impact including habitat disruption and energy use.

By reusing pennies, you’re reducing demand for new raw materials and diverting waste from landfills. It felt good knowing my floor wasn’t just pretty but also aligned with my values around sustainability.

2. The Cost Can Be Surprisingly Low

I was initially worried about how much thousands of pennies would cost. After all, buying coins individually at face value isn’t cheap if you need tens of thousands.

But here’s what helped:

  • Collecting pennies from change jars, friends, family over months reduced cost.
  • Bulk coin sellers offer pennies slightly above face value but still affordable.
  • The main expense beyond coins is epoxy resin and glue—around $100-$250 depending on quality.
  • Doing the installation yourself cuts out expensive labor fees typical with hardwood or tile.

For context:

  • Hardwood flooring averages $6-$12 per sq ft installed.
  • Tile ranges $5-$15 per sq ft installed.
  • Penny floors can be done for $5-$8 per sq ft if you DIY.

3. Visually Stunning and Customizable

The look of a penny floor is unlike anything else—it has this warm copper glow that shifts with light and time.

I found that:

  • Older pennies have richer color because they are mostly copper.
  • Newer pennies have brighter zinc centers but still add interesting texture.
  • You can arrange pennies in patterns (herringbone, spirals) or even mix in other coins like nickels or dimes for contrast.
  • Applying different finishes (glossy vs matte) changes the vibe dramatically.

People often comment on how penny floors become conversation starters because they’re so unusual yet elegant.

4. Durable and Easy to Maintain

I was worried pennies would loosen or dull fast. But epoxy sealing creates a strong surface that:

  • Resists scratches and stains
  • Handles moisture (great for kitchens or bathrooms)
  • Lasts decades if maintained properly

Cleaning is simple too—regular sweeping and damp mopping without harsh chemicals keeps it shining.

Epoxy manufacturers rate their coatings comparable to polished concrete or hardwood finishes in durability.

5. It’s a Fun Project That Builds Skills

This might sound odd but working on my penny floor taught me so much about patience and technique.

You get to:

  • Plan layouts carefully
  • Practice precision gluing
  • Learn epoxy mixing/application methods
  • Solve small problems creatively (dealing with uneven pennies or bubbles)

I found myself proud not just of the finished product but of mastering new skills along the way.

My Personal Penny Floor Journey: Detailed Lessons Learned

Since you’re here for the full scoop, let me share my experience step-by-step so you can avoid some common pitfalls:

Step 1: Planning the Space

I chose my laundry room first—a small 50 sq ft area perfect for testing out the process without committing huge time or money.

I measured carefully and sketched out designs on graph paper. Deciding on a simple grid pattern helped keep things manageable for my first attempt.

Step 2: Collecting Pennies

This was surprisingly fun! I raided my change jars, asked friends and family for donations, and even bought bulk rolls online.

Sorting them was key—I separated old copper pennies from newer zinc cores to create a consistent look. Damaged or corroded coins were tossed out to avoid rough patches later.

Step 3: Preparing the Subfloor

I sanded down plywood until smooth and cleaned thoroughly with vinegar solution to remove dust and oils. This step took longer than expected but made all the difference for adhesion.

Step 4: Gluing Pennies Down

I used construction adhesive applied in small sections so it wouldn’t dry before placing coins.

It took hours spreading glue and pressing each penny tight against neighbors. Some gaps appeared; I filled them with small bits of epoxy later.

Step 5: Epoxy Application

Mixing epoxy was intimidating at first—getting the ratio right is crucial to avoid sticky or cloudy finishes.

I poured slowly over sections and used a squeegee tool to spread evenly without bubbles. Applying multiple thin coats produced the best result instead of one thick layer.

Step 6: Curing Time

Patience was needed here—epoxy takes at least 24 hours per coat to cure fully.

Avoid walking on it too soon or dust settling during drying can embed imperfections.

Outcome

After about three weeks total (including curing times), my penny floor looked amazing—a smooth copper mosaic glowing under my feet!

It has held up well since then—no peeling or discoloration despite heavy use.

Deeper Technical Insights into Penny Flooring Materials

To help you understand why penny floors work so well, here’s some technical background on materials involved:

Copper Properties in Pennies

Older pennies are nearly pure copper (95% copper). Copper is durable, corrosion-resistant, and develops an attractive patina over time which many people love aesthetically.

Since 1982, pennies are mostly zinc (97.5%) coated with a thin layer of copper (2.5%). Zinc cores are softer than copper but still provide decent wear resistance when sealed properly.

Adhesives Used

Construction adhesives like Liquid Nails or Gorilla Glue work well because they bond metal tightly to wood or concrete surfaces without flexing too much over time.

Avoid using regular white glue or hot glue—they won’t hold under foot traffic stress.

Epoxy Resin Chemistry

Epoxy resins consist of two parts—a resin and hardener—that chemically react when mixed causing hardening into a tough plastic layer.

Important qualities:

  • UV resistance prevents yellowing over time.
  • Low viscosity helps epoxy flow around coins filling gaps.
  • High hardness ratings ensure scratch resistance.
  • Water-resistant properties protect underlying wood/concrete from moisture damage.

Case Studies from Real Penny Floor Projects

Here are some detailed reports from others who tackled penny floors recently:

Case Study: The Johnson Family – Seattle

They renovated their kitchen with 120 sq ft of penny flooring made from donated coins collected over years from friends/family jars.

Results:

  • Material cost: $850 total (coins + epoxy + adhesive)
  • Installation: Completed over three weekends with family helping
  • Maintenance: “So far just sweeping daily”
  • Visitors response: “Everyone asks if it’s copper tile!”

Their biggest tip? “Sort your coins ahead of time—it makes layout go faster.”

Case Study: Retail Café – Austin

A boutique café installed 250 sq ft of penny floors in seating areas as part of their branding emphasizing local craftsmanship and sustainability.

Impact:

  • Cost savings vs tile: ~40%
  • Increased customer interest noted by owners
  • Floor holding up under heavy foot traffic at six months post-installation
  • Staff report easy cleaning; no special maintenance needed

They recommend professional installation due to size but said DIY is doable for smaller spaces.
