Your Ultimate Guide on How to Use Epoxy Resin Like a Pro

Epoxy resin has gained immense popularity in the world of DIY and crafting due to its versatility and ability to transform ordinary objects into stunning, glossy creations. Whether you’re a seasoned epoxy enthusiast or just getting started, this comprehensive guide will help you master the art of epoxy resin like a pro. In this Epoxy guide, we’ll cover everything from understanding the basics to troubleshooting common challenges, so you can achieve beautiful results with every project.

Understanding the Basics: What is Epoxy Resin?

Before diving into the world of epoxy, it’s essential to grasp the fundamentals. Epoxy resin is a two-part polymer composed of a resin and a hardener. When these two components are mixed, a chemical reaction occurs, creating a durable and transparent material that can be used for a wide range of applications. Understanding the properties and characteristics of epoxy resin is crucial to successful use.

MPC-100 is a 2-component, 100% solids, self-leveling and high-build epoxy floor coating. It is designed to be used as a protective floor coating on concrete, over an existing epoxy coating or to create metallic/decorative flooring systems. It can also be used as the binder component for resurfacing or patching surfaces exposed to severe and aggressive industrial environments. MPC-100 is a specifically formulated cycloaliphatic coating that reduces water spotting and amine blushing while providing excellent adhesion, abrasion, impact and chemical resistance. 

Choosing the Right Epoxy Resin for Your Project

Selecting the appropriate epoxy resin for your project is a critical decision. Different projects require different types of epoxy resins. Consider factors such as viscosity, curing time, UV resistance, and intended use when making your choice. We’ll explore the various options available and offer guidance on how to match the right epoxy resin to your specific project.

Preparation is Key: How to Prep Your Workspace for Epoxy Application

Remove dust, dirt, grease, oil and all other contaminants with proper cleaner/degreaser. Prepare the surface mechanically as per ICRI-CSP2 profile by diamond grinding to ensure removal of laitance, curing agents and sealers. The compressive strength of a newly poured concrete substrate must be at least 25 MPA (3635 psi) after 28 days cure and at least 1.5 MPA (218 psi) tensile strength. Be careful with condensation (within 10 degrees of the dew point). All cracks, holes and irregularities must be repaired with our epoxy crack filler (MPC-125) prior to applying the coating.

Step-by-Step Guide: Mixing and Applying Epoxy Resin

The products must be conditioned between 18°C (65°F) and 30°C (86°F) prior to application. 

Clear/Colored version: Pre-mix each component separately for 2-3 minutes each. Open a container with 2 parts of component A in it, then add the 1 part of component B to it (mixing ratio 2:1). Mix the components for at least 2-3 minutes using a low-speed drill (300-450 rpm) to reduce air entrapment and to obtain a homogeneous mixture. 

Metallic version: Pre-mix each component separately for 2-3 minutes each. Open a container with 2 parts of component A in it, then add 6 ounces of metallic pigment and mix approximately 1 minute using a low speed drill (150-200 rpm). Let the colored resin sit for at least 30 minutes to ensure proper pigment wetting. Then add 1 part of component B (mixing ratio 2:1). Mix the components for at least 2-3 minutes using a low-speed drill (300-450 rpm) to reduce air entrapment and to obtain a homogeneous mixture. 

Troubleshooting Common Epoxy Resin Challenges

Working with epoxy resin can be a rewarding experience, but like any craft, it comes with its share of challenges. Don’t be discouraged if you encounter issues along the way. This section is dedicated to helping you troubleshoot and overcome common problems that may arise during your epoxy resin projects. Here are some of the most frequent challenges and how to address them:

1. Bubbles in Your Epoxy:

Issue: It’s not uncommon to find small air bubbles trapped in your epoxy surface, which can diminish its clarity and finish.

Solution: To prevent or remove bubbles, use a heat gun or a butane torch to gently pass over the epoxy surface. The heat will cause the bubbles to rise and pop. Additionally, be sure to mix your epoxy thoroughly but avoid vigorous stirring, which can introduce more bubbles.

2. Uneven Curing:

Issue: Sometimes, epoxy may not cure evenly, leading to blotchy or tacky areas on your project.

Solution: Ensure your workspace has a consistent temperature and avoid working in extreme humidity or cold. Use a temperature-controlled curing environment if possible. Properly measure and mix your resin and hardener as per the technical sheet’s instructions to ensure even curing.

3. Improper Adhesion:

Issue: Epoxy may not adhere well to certain surfaces, leading to delamination or peeling.

Solution: Proper surface preparation is key. Clean and sand surfaces to create a rough texture, which helps epoxy bond more effectively. Make sure the surface is free of dust, dirt, and grease. Choose an epoxy resin suitable for the specific material you’re working with, as some resins are formulated for better adhesion to certain surfaces.

4. Excessive Heat and Cracking:

Issue: In high-temperature environments, epoxy can generate excess heat and may crack.

Solution: Use an epoxy resin with a higher heat resistance if you anticipate exposure to high temperatures. Be mindful of the curing environment and avoid direct sunlight during the curing process, as excessive heat can lead to cracking.

5. Incomplete Curing:

Issue: Sometimes, epoxy may remain sticky or uncured even after the recommended curing time.

Solution: Ensure your epoxy is mixed accurately according to the technical sheet. Incomplete curing can be due to improper ratios. If the epoxy is still uncured, you might need to remove it and reapply a fresh layer.

Remember that practice makes perfect when working with epoxy resin. Learning to troubleshoot these common issues will enhance your epoxy craftsmanship over time. As you gain experience, you’ll become more adept at creating flawless epoxy projects. If you encounter a unique challenge not covered here, consult the technical sheet of the specific epoxy you’re using and, if necessary, seek advice from experienced epoxy artists or professionals in the field.
