Complete Guide to Epoxy Resin:
Uses, benefits, and applications of epoxy resin
Transparent epoxy resin has established itself as the preferred material for both artisans and construction professionals in Costa Rica. Its versatility, crystal-clear shine, and high resistance make it ideal for projects ranging from jewelry pieces to coating large surfaces.
If you are looking to transform your spaces or start a creative project, understanding what this "liquid glass" is and how to use it is the first step toward achieving success in your work.
What is transparent epoxy resin and what is it used for?
Epoxy resin is a thermosetting polymer that, when mixed with a catalyst (hardener) agent, changes from a liquid to a solid state. The result is an extremely hard, shiny, and completely transparent surface.
Unlike other conventional varnishes, epoxy resin does not shrink when drying and offers superior protection against moisture and wear. You can use it for:
Encapsulation: preserve objects inside a highly durable transparent layer.
Wood finishes: create the famous "river tables" with professional finishes.
Crafts: ideal for creating keychains, costume jewelry, and custom coasters.
Industrial coatings: high-traffic floors and concrete surface protection.
Benefits of Arti Sur epoxy resin
At EPA, we recommend the Arti Sur line for its formulation designed to offer professional results with great ease of use. By choosing an epoxy resin kit, you get:
Crystal transparency: Prevents yellowing over time, maintaining the original aesthetic of your work.
Self-leveling properties: the mixture spreads evenly, naturally eliminating imperfections during application.
High resistance: withstands impacts and chemicals, and is also extremely easy to clean.
Multi-surface versatility: works perfectly on wood, metal, ceramic, and cement.
For your small projects or if you wish to start in this technique, the Arti Sur Transparent Epoxy Resin 1 Liter is the perfect size to experiment with just the right amount of material.
Step-by-step: how to apply the kit correctly?
Achieving a mirror finish requires you to work with precision. Below, we explain how to use the 1/8 gallon Arti Sur multi-surface epoxy resin kit:
1. Surface preparation
Ensure the base is clean, dry, and free of grease. If you plan to work on wood, we suggest sanding it beforehand so that the resin adheres optimally.
2. Mixing ratio
Most failures in resin applications occur due to improper mixing. Strictly follow the instructions on the container. Generally, a two-part system is used (Resin A and Hardener B).
Pour both components into a clean container.
Mix gently for 3 to 5 minutes, making sure to scrape the walls and bottom of the container well.
3. Eliminate bubbles
It is normal for small bubbles to appear during mixing. Once the resin is poured onto your project, you can use a small heat torch or a blow dryer to eliminate them quickly before the material begins to harden.
4. Curing time
Let your piece rest in a place free of dust and drafts. Although the dry-to-the-touch time is usually 24 hours, full curing can take up to 72 hours, depending on the relative humidity of the environment.

Frequently Asked Questions (FAQ)
How much resin do I need for my project?
This will depend on the thickness of the layer you want to apply. As a general rule, 1 liter of mixture covers approximately 1 square meter with a thickness of 1 mm.
Can it be applied over concrete floors?
Yes, epoxy resin is the basis of the liquid porcelain system. It provides a continuous, joint-free, and highly hygienic finish for your home or business.
Is it heat resistant?
Once the product has fully cured, it withstands moderate temperatures (like a cup of coffee). However, we do not recommend direct contact with pots or pans fresh off the stove.
