A Beginner-Friendly Epoxy Resin Guide for Woodworking Projects
Epoxy resin has become one of the most popular materials in modern woodworking. It is used for river tables, moulds, void fills, charcuterie boards, decorative castings, top coats, and all kinds of custom projects where wood and resin come together.
If you are just getting started, this epoxy resin guide for beginners will help you understand the basics without overcomplicating things. You will learn what epoxy resin is, how it works, what it is used for, and how to avoid some of the most common beginner mistakes.
Quick Take
- Epoxy resin is a two-part material made from resin and hardener.
- It is widely used in woodworking for river tables, void fills, moulds, coatings, and decorative projects.
- Different epoxy products are made for different uses, including deep pours and top coats.
- Mix ratio, temperature, and pour depth matter if you want good results.
- Choosing the right epoxy is one of the most important parts of a successful project.
What Is Epoxy Resin?
Epoxy resin is a two-part system made up of resin and hardener. When the two parts are measured and mixed properly, they react together and cure into a solid material. Depending on the product and the project, the cured epoxy can be clear, coloured, glossy, durable, and highly decorative.
In woodworking, epoxy resin is often used to fill voids, create river effects, cast objects into moulds, coat surfaces, and add colour or depth to a project. It is popular because it can create results that are difficult or impossible to achieve with wood alone.
What Is Epoxy Resin Used for in Woodworking?
Epoxy resin is used in a wide range of woodworking applications. Some projects are structural, some are decorative, and many are a mix of both.
- River tables
- Void fills and knot repairs
- Charcuterie boards and serving boards
- Mould and form pours
- Top coats and protective surface layers
- Decorative castings and inlays
- Pigmented resin art and custom colour effects

How Epoxy Resin Works
Once resin and hardener are mixed together in the correct ratio, a chemical reaction starts. Over time, the liquid mixture begins to harden and eventually cures into a solid mass. The speed of that reaction depends on the product, the mix ratio, the room temperature, the size of the batch, and the depth of the pour.
This is why epoxy projects need more than just good pouring technique. They also need the right product, the right prep, and the right conditions.

Types of Epoxy Resin
Deep Pour Epoxy
Deep pour epoxy is designed for thicker pours, larger voids, river tables, and mould projects where you need to pour resin at a greater depth. It is formulated to manage heat differently than thinner coating products.
Top Coat Epoxy
Top coat epoxy is designed for thinner applications on the surface of a project. It is commonly used when you want a smooth, glossy finish over wood or over a previously cast epoxy section.
Casting and Project-Specific Epoxy
Some epoxy products are designed with specific project types in mind, including mould casting, artistic pours, coating applications, or woodworking pours with particular depth ranges. The exact product matters because the wrong epoxy can lead to bubbles, overheating, poor curing, or disappointing clarity.
The Most Important Rule
The best epoxy resin is not just the one with the clearest finish or the strongest marketing. It is the one that matches your specific project, pour depth, and working conditions.
How to Choose the Right Epoxy Resin
1. Start with the Project Type
A river table, mould pour, void fill, top coat, and charcuterie board all place different demands on epoxy. Start by thinking about what the epoxy is actually being asked to do in the project.
2. Think About Pour Depth
One of the biggest mistakes beginners make is using the wrong epoxy for the depth they want to pour. Thicker pours usually require a product designed for deeper casting applications, while thin surface coats need a product designed for coating.
3. Think About the Final Look
Some projects call for crystal-clear epoxy. Others are meant to be coloured, tinted, opaque, metallic, or artistic. Your pigment choice and the type of epoxy you use both affect the final look.
4. Think About Surface vs Casting Use
If the epoxy is mainly being used as a thick cast material, your needs are different than if it is just going over the surface of a project. This is why top coat and deep pour products should not be treated as interchangeable.
Common Epoxy Resin Problems
Epoxy can produce excellent results, but it is also one of the easiest materials to get wrong when the prep, measuring, or product selection is off.
- Bubbles in the pour
- Yellowing over time
- Sticky or soft uncured epoxy
- Excess heat during curing
- Cloudy or poor-looking results

What You Need Before You Start
Good epoxy results usually come from preparation, not luck. Before you start, it helps to have the right resin, the right pigments or additives, the right mould or form, and a plan for mixing and pouring.
Epoxy Resin and Woodworking Projects
Epoxy is often most effective when paired with the right wood and project type. River tables, live edge serving boards, decorative castings, and custom shelves all benefit from matching the resin choice to the scale and purpose of the project.

Frequently Asked Questions
What is epoxy resin?
Epoxy resin is a two-part material made by combining resin and hardener. When mixed properly, it cures into a solid material used in woodworking, casting, coatings, and decorative resin projects.
What is epoxy resin used for in woodworking?
Epoxy resin is commonly used for river tables, void fills, top coats, moulds, charcuterie boards, inlays, and decorative wood-and-resin projects.
What is the difference between deep pour epoxy and top coat epoxy?
Deep pour epoxy is meant for thicker pours, while top coat epoxy is designed for thinner surface layers. Using the right one matters for cure quality and final appearance.
Why is my epoxy resin not curing properly?
Epoxy may not cure properly if the mix ratio is off, the product was not mixed thoroughly, the temperature is too low, or the wrong epoxy was used for the application.
How do I choose the right epoxy resin for my project?
Choose epoxy based on the project type, the pour depth, the finish you want, and whether you need a deep pour or surface coating product.
