Woodworking enthusiasts often seek new ways to elevate their craft, and UV resin has emerged as a versatile medium for enhancing woodworking projects with unique artistic flair. 

In this article, I will delve into the world of UV resin, shedding light on its techniques, tips, and best practices for woodworking. Whether you’re a seasoned woodworker or just starting, this guide will help you master UV resin to create stunning pieces that capture attention.

The Magic of UV Resin

As a craftsman, it’s thrilling to work with materials like UV resin and UV LED resin. They’re cutting-edge materials that have revolutionized how artisans approach crafting.

Unlike traditional two-component epoxy resins that require meticulous mixing and extended curing times, UV resins come ready to use and cure rapidly when exposed to ultraviolet (UV) light. 

This exceptional advantage opens the door to quick-turnaround projects, encouraging creativity to flow freely.

Choosing the Right Lamp and Understanding Curing Times

Understanding curing times and the appropriate lamp is crucial to unlocking the potential of UV resin. UV LED resin requires a UV LED lamp, while UV resin relies on a UV lamp. 

The curing times may vary depending on the light source, with UV LED lamps offering optimal results. When using UV resin for jewelry, remember that it won’t cure effectively with a UV LED lamp.

As for lamp power, a 6-10W LED lamp usually does the job well for UV LED resin. If you’re using standard UV resin, aim for a 36W UV lamp for the best results. Curing times generally range from a few minutes to around ten minutes for UV resin.

Advantages and Disadvantages of UV Resin and UV LED Resin


UV resin and UV LED resin present a range of compelling advantages that make them a preferred choice for many crafters. The most striking benefit lies in their astonishingly rapid curing time. 

Unlike traditional epoxy resin, which can take 24 to 72 hours to cure, UV resins work their magic within minutes. This swift curing process allows artisans to witness their creations come to life almost instantly, fostering a sense of excitement and accomplishment.

Another significant benefit I’ve found is the elimination of the mixing stage. UV resins are a boon, especially when compared to the sometimes-tedious task of mixing two-component epoxies to just the right proportions.

This streamlined approach simplifies the crafting experience, allowing artisans to dive into their projects without the fuss of precise mixing ratios. This ease of use is particularly advantageous for those seeking efficient solutions for their creative endeavors.


In my experience, it’s clear that while UV resins provide excellent benefits, they come with constraints that are important to acknowledge. One notable drawback is the higher cost of UV resins than epoxy resins, especially in quantity-to-price ratio. 

This cost consideration might influence decisions, particularly for large-scale projects.

Another technical challenge I’ve encountered is shrinkage. As the resin cures, it may undergo slight contraction, leading to potential defects in molds. It can manifest as irregularities, such as waves or uneven surfaces. 

This phenomenon underscores the importance of understanding the resin’s behavior and planning accordingly to mitigate these effects.

Additionally, applying UV resins [1] is best suited for smaller-scale projects due to mold size and depth limitations. 

These resins require transparent molds to facilitate UV light penetration, which ensures even and effective curing throughout the project. The need for suitable molds may restrict the scope of projects, necessitating careful consideration of the intended outcome.

Creating the Ideal Workspace for Resin Crafting

Safety First

When working with resin, I cannot overstate the importance of safety for both yourself and the environment you’re working in. To achieve this, you should know that adhering to a series of safety measures is imperative. 

It’s critical to wear the right protective gear. I always make sure to put on gloves, a gas mask, and protective eyewear. This ensemble acts as a barrier against potential skin irritation and inhalation of resin fumes, safeguarding your well-being throughout the creative process.

Adequate ventilation plays a crucial role in maintaining a safe workspace. Given that liquid resin emits fumes that can be harmful when inhaled, I would highly encourage working in a well-ventilated area.

It prevents the accumulation of harmful vapors, promoting a healthier working environment.

I also stress the importance of keeping your work area secure. It should be out of the way of children and pets to prevent accidental contact with the resin, which could be hazardous.

Preparation and Protection

Adequate preparation and protection measures are essential to ensure a smooth and successful resin crafting session. 

Remove any jewelry that could contact the resin to prevent hindrances or accidents. This precautionary step protects your accessories from inadvertent resin exposure and prevents any interference with the crafting process.

Suitable craft attire should be worn to minimize the risk of resin staining or contact with your clothing. I would also recommend placing a silicone mat beneath your crafting area to protect your work surface.

The silicone mat acts as a protective barrier, shielding your workspace from potential resin spills and drips. Should any resin inadvertently come into contact with the mat, it can be effortlessly cleaned with household alcohol, restoring the pristine condition of your work area.

Comparing Different UV Resin Types

Padico's UV Curing Resin Variations

Padico offers a range of UV-curing resins, each with unique attributes. The original Padico UV resin features longer curing times of 2 to 10 minutes. Star Drop, the fastest-curing UV LED resin, boasts crystal clarity but may shrink in molds. 

Sun Drop is a slower-curing and affordable option, while Moon Drop UV LED resin addresses shrinkage issues while maintaining transparency.

Selecting the Right Resin for Your Project

Choose the resin that aligns with your project’s requirements. Use Padico UV resin for non-LED UV lamps or when a slower cure is desired.

Opt for Star Drop for precise and rapid curing. Sun Drop suits projects where slower curing is acceptable, and Moon Drop is ideal for larger pieces and bead-making.

Preventing Bubbles in UV Resin Art

Bubble-Free Crafting

Bubbles can mar the perfection of resin art. Avoid shaking the resin bottle vigorously to prevent bubble formation. If you’re mixing colors, allow the resin to settle before pouring it into molds. Utilize light-tight cases to preserve colored resin for extended periods.

Bubble Removal Techniques

Heating mats or gentle heat sources can aid in bubble removal. Bubbles rise and burst with heat, ensuring a smoother finish for your resin projects.


UV and LED resin have transformed woodworking and crafting, offering rapid curing and limitless creative potential. By understanding the proper techniques, workspace requirements, and resin types, you can elevate your woodworking projects to new heights. 

I’ve come to appreciate the ease and inventive possibilities that come with UV resin. It’s a journey of artistic discovery and skill, one I’m constantly excited about.
