How to Use Epoxy Resin in Woodworking Projects
Epoxy has become one of the most popular materials in woodworking because it gives builders new ways to solve problems, add colour, create dramatic visual effects, and finish projects with a more custom look. From river tables and live edge boards to mould pours and knot fills, epoxy can be both practical and creative when used the right way.
This guide explains how epoxy is used in woodworking, which types of projects it works best for, what beginners should watch out for, and how to choose the right products for better results.
Quick Take
- Epoxy is widely used in woodworking for river tables, void fills, top coats, moulds, inlays, and decorative projects.
- The best epoxy depends on the job, especially the pour depth and final look you want.
- Epoxy works especially well with live edge wood and custom serving boards.
- Prep, measuring, and mixing matter just as much as the resin itself.
- Good project planning helps avoid bubbles, curing problems, and wasted material.
What Is Epoxy Used for in Woodworking?
Epoxy is used in woodworking anywhere you want to fill, cast, seal, coat, or create a visual effect that wood alone cannot achieve. Some woodworkers use epoxy mainly as a problem-solving material for cracks, knots, and voids. Others use it as a major design feature in projects like river tables and decorative serving boards.

Popular Woodworking Projects That Use Epoxy
River Tables
River tables are one of the best-known epoxy woodworking projects. They combine two wood slabs or boards with an epoxy pour between them to create a river effect. These projects usually rely on the right mould, correct pour depth, and careful planning.
Void Fills and Knot Repairs
Epoxy is often used to fill cracks, knots, checks, and voids in slabs and dimensional lumber. This can help preserve the natural character of the wood while creating a smoother finished surface.
Charcuterie Boards and Serving Boards
Epoxy is commonly used in serving boards to create rivers, fill natural defects, or add decorative colour. These projects are a great way to blend wood grain and resin without the scale of a full table build.
Top Coated Surfaces
Some woodworkers use epoxy as a top coat when they want a glossy, built-up surface over wood or over a previously poured epoxy section. This is a different use case than deep pouring and usually calls for a different product.
Mould and Form Pours
Epoxy is also widely used in moulds and forms for casting projects, small art pieces, sample pours, and custom shapes. A good mould setup can make a big difference in both the process and the finished result.
Choosing the Right Epoxy for Woodworking
One of the biggest mistakes beginners make is treating all epoxy as if it works the same way. In reality, woodworking projects often call for different epoxy types depending on the depth of the pour and the final use of the project.
Deep Pour Epoxy
Deep pour epoxy is the better fit for thicker pours, larger moulds, and river-style projects where the resin needs to cure through a deeper section.
Top Coat Epoxy
Top coat epoxy is made for thinner surface applications where the goal is a coated finish rather than a thick cast section.
Why the Difference Matters
Choosing the wrong epoxy can lead to overheating, bubbles, poor curing, or disappointing clarity. Matching the epoxy to the project is one of the most important parts of getting good results.
Best Results Come from Matching the Epoxy to the Project
A river table, a knot fill, a serving board, and a top coat all use epoxy differently. The more closely your resin matches the actual job, the better your project usually turns out.
Epoxy and Live Edge Wood
Live edge wood and epoxy are a natural fit. The organic shape of the wood works especially well with clear or pigmented resin, whether you are building a river table, serving board, or decorative piece.
This combination is popular because epoxy helps highlight the natural character of the slab instead of covering it up.
Pigments, Colour, and Decorative Effects
One of the biggest reasons woodworkers use epoxy is the ability to add colour, depth, shimmer, opacity, or contrast. Pigments can completely change the feel of a project, from subtle translucent colour to bold metallic effects.
