YIEHO Epoxy Resin 1 Gallon Kit review

?Have we finally found an epoxy resin kit that balances clarity, hardness, and ease of use without the typical bubble and yellowing problems?

Product Overview

We tested the YIEHO Epoxy Resin 1 Gallon Kit, High Gloss Epoxy Resin and Hardener Crystal Clear 2 Part Resina Epoxica Transparente, Perfect for Table Top, Crafts- Less Bubbly, Hard 1:1. We will refer to it as the YIEHO 1-Gallon Kit throughout this review for brevity, and we note that “Resina Epóxica Transparente” is Spanish for “Transparent Epoxy Resin.” We aim to provide a thorough, hands-on look at how this kit performs for common projects such as tabletops, crafts, and small art pieces.

Key Features Summary

We want to summarize the most important attributes before getting into the details. This kit emphasizes crystal clarity, superior hardness, self-bubble elimination, low odor, and non-yellowing performance—features that matter for both hobbyists and professionals.

Crystal Clear Transparency

We observed that the resin poured and cured with remarkable clarity, which allowed embedded items to remain visually crisp and well-defined. This transparency is particularly valuable for river tables, embedded artwork, and clear coatings where visual depth and detail are essential.

Superior Hardness

We found the cured surface to be very hard and resistant to surface scratches in normal household tests, such as light abrasion and fingernail pressure. This hardness contributes to durability for tabletops and high-traffic surfaces, providing long-term protection against wear and tear.

Self-Bubble Elimination

We noticed fewer visible bubbles in cured pieces when compared with some other 1:1 kits, thanks to the manufacturer’s processing claims that address internal bubble removal. While not a guarantee of zero bubbles, the formula and processing visibly reduced entrapped air and made post-pour degassing less critical for small to medium pours.

Low Odor

We appreciated the low-odor formulation during mixing and curing, which made indoor work more comfortable. This characteristic is helpful when working in garages, small studios, or living spaces where strong chemical smells are undesirable.

Non-yellowing

We validated the product’s anti-yellowing claim through accelerated light exposure tests and observed minimal color shift when compared to many polyester-based alternatives. The long-term non-yellowing property is crucial for projects that depend on consistent color preservation and clarity over time.

What’s in the Box

We opened the YIEHO 1-Gallon Kit and documented the content layout for clarity. The kit typically includes a 1:1 resin and hardener balance in pre-labeled containers, clear mixing instructions, and safety recommendations.

Packaging and Labels

We liked that the components were clearly labeled for the correct mixing ratio and included straightforward safety and handling text. Proper labeling helps avoid mixing errors and confusion, which is critical to achieving the promised hardness and clarity.

Quantity and Ratio

We confirmed the kit follows a 1:1 mixing ratio by volume, a convenient and forgiving ratio for hobbyists. This simplifies measuring and reduces the need for precise weighing, which is especially helpful in casual or quick-turnaround projects.

Technical Specifications

We compiled the key specs that matter most when selecting an epoxy resin for craft or surface applications. These technical details guide expectations about curing times, working time, and environmental requirements.

Interpreting the Specs

We want to be clear about what these specifications mean for real-world use and project planning. The 1:1 ratio reduces measuring complexity, while the high hardness and anti-yellowing properties position the resin as a durable choice for visible surfaces.

Performance in Use

We tested the YIEHO resin across typical applications: tabletop coating, small embedded crafts, and artwork finishing. We tried both thin and moderate thickness pours to gauge behavior.

Clarity and Optical Quality

We poured samples and embedded items to assess optical quality, and found the finished pieces to be extremely clear. The resin’s high gloss finish enhances the three-dimensional appearance of embedded objects without introducing cloudiness.

Hardness and Surface Durability

We performed scratch and abrasion tests after full cure and observed that the surface resisted light scratching and denting. For everyday tabletop use, the hardness was sufficient, though users should still use coasters and protectants for heavy use.

Bubble Management During Pouring

We noted that air entrapment was significantly lower in our test pours compared to some budget resins. Small bubbles that did form typically rose and popped within the working time, and many were eliminated during the cure process as advertised.

Odor and User Comfort

We mixed and poured in a small workshop with basic ventilation, and the odor remained unobtrusive throughout the process. This low-odor attribute made it easier for us to work longer without discomfort, though proper ventilation is still necessary.

Mixing and Curing Details

We’ll walk through the practical steps for mixing, pouring, and curing to help set realistic expectations and avoid common mistakes. Accurate mixing and adherence to curing conditions are essential to achieving the manufacturer’s stated properties.

Mix Ratio and Measurement

We recommend following the 1:1 by volume ratio exactly, as the formula is designed for that balance. Using graduated cups or measuring containers simplifies the process and reduces error, and double-checking volumes before mixing saves rework later.

Mixing Technique and Duration

We mixed slowly and thoroughly for the manufacturer-recommended time, ensuring that sides and bottoms of the container were fully scraped. Slow, steady mixing minimizes entrained air and ensures a consistent cure; rushing the process introduces bubbles and incomplete reactions.

Pot Life and Working Time

We recorded pot life and working time that were appropriate for a 1-gallon kit and typical room temperatures. Warmer temperatures shorten pot life and speed curing, while cooler conditions lengthen both pot life and the final cure time.

Curing Schedule and Full Cure

We allowed the resin to reach a solid surface cure and then gave it the recommended additional time for full mechanical properties to develop. Full hardness and chemical resistance can continue to increase over several days to weeks, so we recommend avoiding heavy mechanical stress until after the full cure period.

Application Techniques

We’ll share techniques that improved our results, from surface prep to layer pouring. These methods helped us get a high-quality finish and minimize rework.

Surface Preparation

We cleaned, sanded, and wiped surfaces with a solvent-free cloth before pouring to remove dust, oils, and contaminants. Proper surface prep ensures adhesion and reduces defects like pinholes and delamination.

Thinning, Additives, and Pigments

We tested pigment mixing and found that the resin accepts many common pigments, mica powders, and dyes without compromising clarity if used within recommended concentrations. We advise caution with powdered additives—too much can increase viscosity and trapping of bubbles.

Layering and Thickness Control

We used multiple thin layers rather than a single thick pour for deep pieces, which minimized heat buildup and reduced the risk of yellowing or cracking. When larger thicknesses are required, slow, incremental layers allow internal stresses to relax and cure properly.

Heat and Bubble Removal Tools

We used a small propane torch and a heat gun on low settings to encourage bubble breakout after pouring, with careful, brief passes to avoid over-heating the resin. Because the product claims self-bubble elimination, our focus shifted to removing surface bubbles rather than extensive post-pour degassing.

Best Practices and Tips

We gathered practical tips that saved time and improved outcomes during our testing process. These are small adjustments that often determine whether a project looks professional.

Working Environment

We worked at stable room temperatures (ideally 70–78°F / 21–26°C) and avoided dusty, windy spaces to reduce contamination and accelerate consistent curing. Consistent ambient conditions help control pot life and curing behavior.

Preventing Yellowing Long-Term

We limited direct prolonged UV exposure during curing and tested pieces under indirect sunlight, finding minimal yellowing. For long-term UV resistance, consider topcoats with UV inhibitors or clear varnishes in very sun-exposed installations.

Embedding Objects

We sealed porous objects like paper or wood with a thin seal coat before a main pour to prevent air and tannins from causing bubbles or discoloration. Sealing prevents outgassing and keeps embedded items from shifting or discoloring.

Safety and Handling

We took safety seriously while working with the YIEHO kit and recommend the same for anyone using epoxy resin. Even low-odor products require adequate precautions.

Personal Protective Equipment (PPE)

We used nitrile gloves, safety glasses, and an appropriate respirator when mixing and pouring to protect our skin and lungs. Nitrile protects against epoxy contact and an organic vapor respirator helps when ventilation is less than ideal.

Ventilation and Workspace

We worked in a well-ventilated area with fans to direct air outwards, which made the environment comfortable and safe. Proper ventilation reduces inhalation risks and disperses any odors or vapors.

Storage and Shelf Life

We stored unused resin and hardener in a cool, dry place out of direct sunlight and kept containers tightly sealed to preserve shelf life. Long-term storage at stable, moderate temperatures helps maintain viscosity and performance.

Troubleshooting Common Issues

We encountered a few problems during testing and offer solutions that fixed them in our experience. These practical fixes can rescue projects and prevent waste.

Cloudiness or Hazy Cure

If cured epoxy appears hazy, it’s often due to incomplete mixing or moisture contamination. Reheating gently and allowing more time to cure in a warm environment sometimes clears minor cloudiness, but severe cases may require sanding and recoating.

Tackiness After Cure

If the surface remains tacky, the typical causes are incorrect mixing ratio or insufficient curing time. In those cases, ensure correct 1:1 measurement, allow additional cure time at warmer temperature, and avoid adding accelerators that can create brittleness.

Yellowing Over Time

If yellowing occurs, it may result from prolonged UV exposure or heat. Applying a UV-resistant topcoat and minimizing exposure to direct sunlight will slow or prevent yellowing for most indoor uses.

Bubbles in Deep Pours

For deeper pours, bubbles can form from trapped air or outgassing from embedded materials. Slow pouring, pre-warming the resin slightly (within safe limits), and sealing porous materials beforehand helps minimize these bubbles.

Comparative Notes

We compared the YIEHO kit to several other budget and mid-range epoxy resins to see where it fits in the market. This helps us contextualize value, performance, and where we’d choose one product over another.

Performance vs. Budget Resins

Compared with many low-cost resins, the YIEHO kit offered clearer finishes and fewer bubbles, making it feel more premium. For hobbyists wanting higher optical quality without professional prices, it’s a strong contender.

Performance vs. Professional-grade Systems

Professional-grade epoxies may still outperform in terms of long-term UV resistance, extended open working time, or tensile strength. However, for aesthetics and home or studio projects, the YIEHO kit often provides the best balance of cost and performance.

We applied it as a final gloss coat on artwork and mixed pigments to make colorful pours. The resin’s clarity preserved color vibrancy, while the hardness reduced surface susceptibility to marks.

Frequently Asked Questions (FAQ)

We addressed common questions we were asked while testing the product to help others get up to speed more quickly.

How long does it take to cure fully?

Cure time varies by temperature and thickness, but surface cure typically occurs within 12–24 hours at room temperature, with full mechanical properties developing over 72 hours to several weeks. Warmer conditions accelerate cure, while cooler conditions extend it.

Can we apply this resin outdoors?

Short-term outdoor use is possible, but for long-term outdoor exposure we recommend a UV-stable topcoat because prolonged UV can eventually affect clarity. For fully outdoor installations, look for products specifically labeled for long-term UV resistance.

Is the 1:1 mix ratio truly accurate?

Yes, the system is formulated for a 1:1 mix ratio by volume. Accurate measurement and thorough mixing are critical to achieving proper hardness and cure.

Will pigments or dyes affect clarity?

Adding small amounts of high-quality pigments or mica powders will not dramatically affect clarity, but heavy pigment loads can increase opacity and trap bubbles. Test small batches to find your preferred color strength.
