What is Epoxy Resin?
Epoxy resin is a two-part synthetic polymer made from mixing two chemicals:
- Resin (Part A) – usually a Bisphenol-A or Bisphenol-F based liquid
- Hardener (Part B) – typically made with amines
When mixed together, a chemical reaction causes the mixture to cure into a solid, plastic-like surface. There’s no evaporation like with paint or varnish—epoxy cures through chemistry, not air-drying. It’s self-leveling, waterproof, and incredibly durable once fully cured. On wood furniture, it creates a high-gloss, crystal-clear finish that highlights natural wood grain and adds a layer of protection that’s hard to beat.
A Little History of Epoxy Resin
Epoxy resins were developed in the 1930s by German and Swiss chemists, and commercial production took off in the 1940s. While their first claim to fame was in the aerospace and electrical industries (hello, super-strong adhesive!), epoxy quickly found its way into marine and woodworking applications thanks to its extreme durability and waterproof nature.
Today, epoxy resin is beloved in the DIY and woodworking worlds for coating, filling, bonding, and beautifying wood surfaces—especially when a glass-like shine is on the wishlist.
Fun Fact: NASA uses epoxy resin in spacecraft construction due to its strength-to-weight ratio.
Where and Why to Use Epoxy Resin
Epoxy resin is like the glam red lipstick of the furniture world—bold, glossy, and unforgettable. But just like lipstick, it’s not always the right fit for the situation. Here’s a quick-glance guide to help you decide if this dazzling finish is the right match for your project.
| Best For | What’s to Love | What’s Not to Love |
|---|---|---|
| Table and bar tops | Glass-like, high-gloss finish that makes wood grain pop | Prone to yellowing over time (especially in sunlight) |
| High-use furniture (e.g., desks, coffee tables) | Extremely durable—resists scratches, water, and everyday wear | Long cure time—can take 3–7 days to fully harden |
| Decorative surfaces and artistic projects | Self-leveling and easy to pour in thick coats for dramatic results | Sensitive to mixing ratios—must be exact or it won’t cure properly |
| Filling voids, cracks, and live edges | Acts as a clear filler, sealing and stabilizing defects beautifully | Bubbles can form—requires heat gun or torch to remove |
| Custom pieces that need waterproofing | Completely waterproof once cured—no need for coasters or special care | Cannot be spot-repaired—fixes require full sanding and re-pouring |
| Showstopper finishes that wow on first glance | Enhances depth and clarity of wood tones like no other finish | Must be applied in controlled temps and humidity (ideally 60–80°F, 40–60% humidity) |
| Bonds tightly to wood | Susceptible to heat damage (use coasters!) | |
| Completely customizable – can be tinted or embedded with objects | Tricky cleanup (requires acetone or denatured alcohol before curing) |

What’s in the Finishing Toolkit?
Before you get started, you’ll need these tools and supplies!
Tools
- Silicone measuring cups and silicone stir sticks
- Nitrile gloves (a must!)
- Goggles
- Respirator
- Level surface + plastic drop cloth for protection
- Propane torch or heat gun (for popping bubbles)
- Finishing sander and sanding pads
- Metal scraper
Materials
- Epoxy resin (resin + hardener, typically mixed 1:1)
- Aluminum foil
- Dewaxed shellac (optional but helpful)
- Optional Add-ons:
- Color pigments or mica powders for effects
- Silicone molds or edging tape for creative projects
Pro Tips: Before You Begin
- Pour in a dust-free, temperature-controlled space (60–80°F, 40–60% humidity).
- Mix SLOWLY to avoid introducing bubbles.
- Always measure by volume, not weight.
- Don’t skimp on surface prep—clean, sanded, sealed wood is best.
How to Apply Epoxy Resin
- Prep the Wood
Sand the surface smooth (usually 120–220 grit). Remove any dust with a tack cloth. Make sure the surface is clean, dry, and level. Use a seal coat if your wood is porous (this is where the de-waxed shellac comes into play)—it helps prevent air bubbles from escaping and causing pitting. - Protect the Work Area
Place the plastic drop cloth on the floor under your project. Wrap or tape aluminum foil to any areas that you do not want sealed with resin. (For example, I wrapped the legs of this table in aluminum foil to protect them from drips. It worked perfectly!) - Mix the Resin
Combine the resin and hardener exactly as directed (usually 1:1 by volume). Mix slowly for 3–5 minutes until the mixture is crystal clear with no streaks. Scrape the sides and bottom of your container while stirring. - Pour the Resin
Pour your resin in the center and spread gently with a silicone scraper. Don’t overwork it—epoxy will self-level! - Pop the Bubbles
Use a propane torch or heat gun to gently wave over the surface, popping bubbles as you go. Be careful not to scorch the resin or the wood. - Let It Cure
Most epoxies cure in 12–72 hours, depending on the brand and temperature. Cover your work to keep out dust, and don’t touch it while it cures! - Trim Drips and Runs
Use the heat gun to soften any drips or runs along the edge of the project. These can then be scraped off with the metal scraper.
Application Best Practices
- Temperature: Ideal room temp is 70–75°F.
- Humidity: Keep humidity below 85% for best curing and clarity.
- Drying Time: Initial cure happens in 12–24 hours. Full cure in 3–7 days, depending on brand.
- Coats: For most furniture pieces, 2–3 coats offer max durability. Lightly sand between coats for best adhesion.

When and How to Refresh Epoxy Resin Furniture Finish
Before diving into refinishing or removal, it’s essential to assess whether your epoxy resin surface needs attention. Over time, epoxy can become dull, scratched, or slightly yellowed. Minor issues like these often require just a light refresh rather than a complete overhaul.
Signs it’s time to refresh:
- The surface appears dull or has lost its original shine.
- Minor scratches or scuffs are visible.
- Slight yellowing, especially in areas exposed to sunlight.
Quick Refresh Steps:
- Clean the Surface: Use a mild soap and water solution to remove any dirt or residues.
- Light Sanding: Gently sand the surface with fine-grit sandpaper (around 400-600 grit) to scuff it slightly, promoting better adhesion for the new layer.
- Apply a Fresh Coat: Mix a small batch of epoxy resin and apply a thin layer over the sanded area. This will restore clarity and shine.
This approach is ideal for surfaces that are structurally sound but are showing a little wear and tear from life.
Refinishing Epoxy Resin
If your epoxy surface has more pronounced issues—like deeper scratches, uneven areas, or significant dullness—a more thorough refinishing is in order.
Refinishing Steps:
- Deep Cleaning: Ensure the surface is free from contaminants.
- Sanding: Use medium-grit sandpaper (around 220 grit) to remove the existing finish uniformly.
- Clean Again: Wipe away all sanding dust with a cloth dampened with isopropyl alcohol and let it dry completely.
- Apply New Epoxy Layer: Mix and pour a new layer of epoxy resin, ensuring even coverage.
- Bubble Removal: Use a heat gun or torch to eliminate any air bubbles.
- Curing: Allow the resin to cure as per the manufacturer’s instructions, typically 24-72 hours.
This process rejuvenates the surface, making it look brand new.
Removing Epoxy Resin
In cases where the epoxy is extensively damaged—such as deep cracks, severe yellowing, or improper curing—removal might be the best option.
Removal Steps:
- Safety First: Wear appropriate protective gear, including gloves, a respirator, and eye protection.
- Heat Application: Use a heat gun to soften the epoxy, making it easier to remove.
- Scraping: Gently scrape off the softened epoxy using a putty knife or scraper.
- Sanding: After the bulk is removed, sand the surface to eliminate any remaining residue.
- Clean Up: Wipe the area clean with a suitable solvent like acetone.
Once the old epoxy is entirely removed, you can proceed with refinishing the surface as desired.
Pro Tip: This is a job best done outside with LOTS of ventilation. Regardless, still wear your respirator and goggles, as the resin will either turn into some nasty plastic dust or fill you with fumes. Be creatively conscious, my friend!
Epoxy Resin Care 101
Once your masterpiece is cured, you want to keep it looking fabulous! Here’s how to care for epoxy-finished furniture:
| Care Tip | Why It Matters |
|---|---|
| Use soft cloths | Avoid scratches from rough sponges or scrubbers |
| Clean spills promptly | Epoxy is resistant, not invincible—especially to strong solvents |
| Avoid heat | Use trivets! Epoxy can soften with sustained heat over 120°F |
| Minimize scratches | Avoid dragging items across the surface and use coasters, and placemats to prevent scratches. |
| Skip waxes | They can dull the surface—use a plastic polish instead |
| Refresh with polish | Use automotive or resin polish to restore shine every few months |
| Avoid extreme temperatures | Store in a climate-controlled space (extreme temps can cause cracking). |
Pro Tips for Epoxy Success
- Mix thoroughly: Under-mixing leads to sticky, uncured surfaces—always follow the brand’s instructions.
- Temperature matters: Ideal working temp is 70–75°F. Too cold and resin stays tacky; too hot and it cures too fast!
- Dust is your enemy: Work in a clean, dust-free area and cover your project while curing.
- Seal first: On live-edge or open-grain wood, a thin seal coat helps eliminate bubbles.
- Protect your hands: Always wear nitrile gloves—epoxy is sticky and unforgiving.
- Keep it level: Use a level surface and protect your workspace.
- Practice patience: Don’t rush the cure—cover your piece and walk away!
- Stay in the shade: Never apply epoxy in direct sunlight—it speeds up curing unevenly and can cause bubbles.
- Choose wisely: Use UV-resistant epoxy if the piece will be exposed to light.
Common Epoxy Resin Mistakes (And How to Fix Them)
| Mistake | Fix |
| Sticky or soft finish | Mixing ratio was off—remove and re-pour |
| Bubbles or dimples | Use heat gun/torch immediately after pouring |
| Yellowing finish | Choose UV-resistant products or add a UV stabilizer |
| Uneven surface | Make sure your project is level before pouring |
| Scratches over time | Buff with plastic polish or recoat |
