Epoxy resin has become an incredibly popular material for creators, crafters, and DIY enthusiasts. When combined with wood, epoxy resin allows you to create beautiful, glossy, and unique pieces of art, decor, and furniture. From river tables to live edge slabs, working with epoxy resin and wood opens up endless creative possibilities.

If you’re new to working with epoxy resin, the process can seem a bit daunting. But with some simple tips, materials, and safety precautions, you’ll be ready to start making gorgeous epoxy resin wood projects. This beginner’s guide will walk you through everything you need to know to get started.

Benefits of Using Epoxy Resin with Wood

There are several reasons why woodworkers and crafters love using epoxy resin:

  • Protects and preserves wood – The epoxy resin seals and protects the wood, preventing moisture damage, scratches, and wear. This helps preserve the natural beauty of the wood.
  • Enhances depth and dimensions – Epoxy resin is crystal clear, allowing you to see all the natural details of the wood grain and texture shine through. The resin adds depth and dimension.
  • Creates smooth, glossy finish – After curing, the epoxy resin forms a thick, glossy, glass-like coating over the wood. This sleek finish really makes the wood pop.
  • Fill cracks and holes – The liquid resin can fill knots, cracks, holes, and imperfections in the wood, creating a flawless look.
  • Adheres materials – You can adhere other materials like photos or glitter into the epoxy resin to create unique designs and effects.
  • Limitless creativity – With endless techniques like river tables, charcuterie boards, live edge slabs, and more, epoxy resin takes woodworking to a whole new creative level.

So if you want to take your woodworking projects to the next level with beautiful, glossy, polished results, epoxy resin is perfect. Now let’s go over the basics of how to work with it.

Choosing Your Epoxy Resin

When searching for epoxy resin, you’ll find different types available. The resin you choose will depend on your specific project needs. Here are the most common options:

Epoxy Casting Resin

This high-viscosity resin is great for coating and encapsulating objects. It is thick enough to fully coat and self-level on wood with a glossy finish. Casting resins are ideal for wood tables, live edge slabs, charcuterie boards, and jewelry. They resist yellowing.

Epoxy Laminating Resin

With a lower viscosity, these resins are designed for coating fabrics and laminating layers. They absorb into materials better than casting resin. Use for wood finishes and fiberglass coating. They tend to yellow over time.

Epoxy Adhesive

These have very low viscosities and bond tenaciously to materials. They are perfect to adhere wood, metal, glass, stone, and more. Use adhesive epoxy to join wood pieces. Goes on thin and cures transparent.

Epoxy Sealers

These thin resins penetrate into porous surfaces to seal and protect them. They make an excellent primer and sealer for wood before applying epoxy resin over the top. Helps prevent bubbles from porous wood.

For most woodworking projects, a high-quality epoxy casting resin works best to fully coat and seal the wood. Make sure to choose a brand formulated for coating wood that resists yellowing.

Selecting Your Wood

You have endless options when choosing wood for epoxy resin projects. Consider hardness, porosity, color, grain patterns, board thickness, and more.

  • Hardwoods like maple, oak, walnut, teak, and mahogany work beautifully, providing rich color and grain. Softer woods may dent.
  • Porous woods like pine absorb more resin, which can cause bubbles. Use a sealing coat first.
  • Light woods like birch allow more light through the resin, creating a bright, luminous effect.
  • Darker woods like walnut show less grain but dramatic color effects.
  • For wood slabs, select boards at least 1.5″ thick to support the weight of resin.

Consider the visual look you want to achieve. Play around with different wood species, grains, colors, shapes, and textures. Also factor in how the wood will be used – if making a dining table, choose durable, harder woods.

How to Prepare the Wood

Proper preparation is crucial for success with epoxy resin and wood. Follow these key steps:

  1. Cut and sand – Cut your wood to the desired size and shape with a table saw or circular saw. Sand starting with 80 grit up to at least 220 grit for a smooth finish.
  2. Seal porous woods – Woods like pine and cedar are quite porous. Use an epoxy sealing coat or sanding sealer first to prevent air bubbles from escaping through the wood into your epoxy topcoat.
  3. Clean and dry – Wipe wood with acetone or denatured alcohol to remove oils, dust, or debris. Allow to fully dry. Wood moisture can ruin epoxy results.
  4. Fill imperfections (optional) – Use colored epoxy resin to fill any cracks, holes, or dents in the wood if desired. Let cure completely.
  5. Add accent colors (optional) – For added interest, you can use artist oil paints, alcohol inks, or powdered pigments to color the wood before coating with clear epoxy resin.

Properly preparing your wood will allow the epoxy resin to fully cure and adhere correctly for a flawless glossy finish.

How to Mix and Apply Epoxy Resin

Once your wood is prepped, it’s time to mix and pour the epoxy resin. Follow all safety precautions when working with epoxy resins – work in a well-ventilated area and wear gloves and goggles. Here’s an overview of the process:

Mixing Epoxy Resin

  1. Plan your project size to buy the right epoxy resin amount. Mix only as much as you can use before it cures.
  2. Combine the resin and hardener at the proper mixing ratio. This is usually 2:1 or 1:1 resin to hardener by volume.
  3. Mix thoroughly for 3-5 minutes, scraping the sides and bottom of the container. Mixing properly is critical – don’t rush this step!
  4. Optional – you can add powdered colorants or other additives once fully mixed.
  5. Allow to sit for a few minutes to let air bubbles rise and pop.

You now have mixed epoxy resin ready to pour.

Applying Epoxy Resin

  1. Pour the resin slowly and steadily over the surface to control the flow. Use a plastic spreader to distribute evenly.
  2. Torch the surface lightly with a propane torch to pop any remaining air bubbles.
  3. For second coats, reapply within the epoxy’s open working time, usually within 24 hours.
  4. Allow the resin to fully cure, usually 24-48 hours until hardened.
  5. Once cured, the surface can be sanded starting with 220 grit up to 3000 grit for a high-gloss polished finish.
  6. Buff and polish the epoxy coating using polishing pads and compounds if desired.

Applying the epoxy resin is an easy process. The key is taking the time to properly mix, pour, spread, and allow for full curing to achieve flawless results.

Epoxy Resin Wood Project Ideas

Now that you know the basics, it’s time for the fun part – deciding what to make! Here are some great beginner project ideas:

  • River table – Fill cracks and voids in a wood slab with colored epoxy resin to look like a river flowing down the table.
  • Live edge slab – Showcase the natural shape of wood with bark accents using glossy epoxy.
