What exactly is LET’S RESIN Bubble Free Epoxy Resin?

This is a two-part, 1:1 epoxy resin system designed for crafts, coatings, and casting small objects—especially where clarity and minimal bubbles matter. The 23oz kit is sized for beginners and hobbyists: enough to make multiple pendants, coasters, dominos, bookmarks, or a handful of small molds and toppers, with a bit of room to experiment with alcohol ink techniques.

Notably, the formulation is tailored to excel with alcohol inks. If you’ve tried Petri-style drops (where pigments bloom downward through the resin to create ethereal floral and galaxy effects), you know not all resins behave the same. LET’S RESIN tuned this kit to achieve clean blooms with the right balance of viscosity and cure kinetics so your inks have time to spread gracefully before locking into place.

Who it’s best for

  • Beginners who want a forgiving, bubble-resistant, low-odor resin with a simple 1:1 mix ratio
  • Artists exploring the Daniel Cooper-inspired Petri effect and other alcohol ink techniques
  • Makers creating crystal-clear jewelry, keychains, bookmarks, coasters, and small castings
  • Mixed-media artists coating canvases or adding a glossy, glassy top layer to artwork
  • Hobbyists making small wood inlays, paperweights, or floral keepsakes
  • Crafters who need better UV resistance to help slow yellowing over time

If that’s you, this kit hits a sweet spot between ease-of-use and clarity—especially if you value low bubble formation without wrestling with your torch every 10 seconds.

What’s included

  • Two bottles: Resin (Part A) and Hardener (Part B) totaling 23 fl oz
  • A measuring/mixing cup
  • Stir stick
  • Instructions

The starter-friendly add-ins (cup + stick) are great if you’re just building your setup or want to do a quick test pour without rummaging for supplies.

Key features and real-world benefits

1) Alcohol ink optimized (Daniel Cooper Petri effect)

If you’ve ever tried to capture those mesmerizing “bloom” or “cloud” effects with alcohol inks, the resin’s viscosity and open time are critical. Too thick and your inks clump on the surface; too runny or fast-cure and they spread too chaotically or lock up before they bloom.

LET’S RESIN’s craft-specific formulation strikes a nice balance for:

  • Petri blooms
  • Cloud effects
  • Butterfly-like wing patterns
  • Nebula and galaxy swirls

Pair this with a white alcohol ink “sinker” (often used in Petri techniques), and you’ll see more predictable sinking and defined layers. If you’re following Daniel Cooper tutorials or similar Petri ink guides, this resin responds consistently—making it easier to replicate those compelling results.

2) Crystal clarity with enhanced UV protection

Clarity is the difference between “okay” and “wow.” This formula pours water-clear and self-levels to a glossy finish, making inclusions and metallics pop. The manufacturer highlights 3X UV resistance compared to standard craft resins—protection that helps slow the natural yellowing of epoxies. If your work sees window light or you’re gifting/selling pieces, that extra protection matters. No epoxy is totally immune to UV over many years, but added UV inhibitors help preserve clarity longer.

Use cases where UV matters:

  • Coasters placed near windows
  • Jewelry that sees outdoor light
  • Clear keychains with embedded flowers, leaves, or photos
  • Sealed artwork and canvases

3) “Bubble Free” and low odor

Beginners often battle bubbles. While no resin is magically bubble-proof in every scenario (especially with porous fillers or botanical inclusions), this kit noticeably reduces trapped air when:

  • Warmed slightly before mixing (more on that below)
  • Mixed slowly with scraping of sides and bottoms
  • Poured in thin layers
  • Gently torched or heat-gunned after pour

Low odor is another plus—more comfortable sessions in a ventilated space. It’s still a reactive chemical system, so use PPE and good airflow, but you don’t get overwhelmed by fumes.

4) Self-leveling, durable, and scratch resistant

This resin flows smoothly and levels out nicely, leaving a high-gloss finish with minimal ripples. Once cured, it’s tough—great for jewelry and keychains that bounce around in bags or on tables. For coasters and small table inlays, that scratch resistance helps maintain that glassy look.

5) Easy, 1:1 by volume mix ratio

Mixing is straightforward: equal parts A and B by volume. For anyone intimidated by variable ratios or gram scales, this is as simple as it gets. Just measure carefully, mix thoroughly, and pour.

Pro tip: Keep your workspace around the temperature recommended on the label (many craft resins like 70–75°F / 21–24°C). Warmer rooms reduce viscosity and help bubble release; colder rooms can thicken resin and slow curing.

Hands-on performance: What I experienced

I pulled together multiple small projects to stress test this kit across common use cases.

  1. Jewelry bezels with mica and foil flakes
  • Clarity: Excellent. Foils gleamed and mica shimmered with depth.
  • Bubbles: Minimal. A quick pass with a small torch (held at a safe distance) popped surface microbubbles quickly.
  • Set and finish: Pours leveled nicely—edges stayed clean with little dome distortion.
  1. Alcohol ink Petri effect in shallow molds
  • Flow: Inks bloomed and sank predictably when paired with a white alcohol ink sinker.
  • Layering: Multiple color drops retained separation, creating intricate petal-like structures.
  • Timing: There was enough open time to work without panicking, but I still recommend prepping inks and tools in advance.
  1. Coasters with inclusions
  • Inclusion behavior: Dried florals worked well after a quick seal (I use a light spray sealer to reduce moisture-related microbubbles).
  • UV: The extra UV inhibitors give peace of mind for coasters that see daylight—especially if you’re selling or gifting them.
  1. Art topcoat on a small panel
  • Leveling: Smooth, glossy, glass-like finish with minimal torching required.
  • Dust control: I still recommend a clean box or cover while curing; clarity means dust will show if it lands.

Overall, this kit hits a sweet spot between clarity, control with alcohol inks, and ease-of-use. The “Bubble Free” label really shows in basic pours and simple molds; if you’re embedding porous, damp, or uneven materials, your technique and prep will still matter—but the resin itself isn’t fighting you.

Step-by-step: How to create the alcohol ink Petri effect with this resin

Here’s a beginner-friendly workflow adapted to resins like LET’S RESIN that pair nicely with alcohol inks. Always cross-check timing and temperature details on the product label and in the tutorial you’re following (Daniel Cooper’s or others), then adjust to your environment.

What you’ll need:

  • LET’S RESIN Bubble Free Epoxy Resin (Part A + Part B)
  • Silicone molds or bezels (clean and dry)
  • Alcohol inks (several colors + a white “sinker”)
  • Nitrile gloves, protective surface cover, apron
  • Mixing cup + stir stick (included)
  • Heat gun or small craft torch (optional but helpful)
  • Toothpicks or silicone tools for fine adjustments
  • Dust cover for curing (a clear box or container works well)

Instructions:

  1. Prep your space:
    • Aim for a dust-free area with good ventilation.
    • Warm bottles in a bowl of warm (not hot) water if they feel thick or look cloudy from cold. Dry the bottles thoroughly before opening (water drops create defects).
  2. Measure and mix (1:1 by volume):
    • Pour equal parts A and B. Mix slowly for a few minutes, scraping sides and bottom until uniform. You’re minimizing air here—slow and steady wins.
  3. Pour your base layer:
    • Pour a shallow layer into your mold or bezel. For many Petri effects, a thinner base layer helps inks bloom more elegantly.
  4. Drop your inks:
    • Start with a pattern of colored alcohol ink drops on the surface.
    • Follow each color drop with a small drop of white sinker in the same spot. Alternate color/white/color/white to push colors downward.
    • Work in small, strategic drops rather than flooding the surface. Watch how colors begin to spread and sink.
  5. Gentle heat, if needed:
    • A quick pass with a heat gun (lowest setting) can pop surface microbubbles and encourage gentle motion. Avoid aggressive heat that might blow inks together or scorch the resin.
  6. Let it develop:
    • Early on, the piece will morph. Resist the urge to overwork it. The magic happens as inks sink and the resin begins to set.
  7. Optional second pour:
    • If your project needs a flat back or a protective cap layer, wait until the first layer is set to the recommended tack level or fully cured per the label, then pour a clear top.
  8. Cover and cure:
    • Place a dust cover over your piece and allow it to cure as indicated on the product directions. Temperature impacts cure time; colder rooms slow everything down.

Tips:

  • Use less white than you think—too much can muddy colors.
  • Test inks on a small scrap pour to understand how they behave in your room conditions.
  • Keep moisture away: damp inclusions can cause froth or haze.

Tips to get a bubble-free, glassy finish

  • Warm resin bottles slightly in a warm water bath before mixing; dry well to avoid introducing moisture.
  • Mix slowly and scrape the sides and bottom of the cup to fully incorporate.
  • Pour in thinner layers; deep, single-pour volumes trap bubbles more easily.
  • Use a gentle pass with a heat gun or craft torch shortly after pouring—don’t linger in one spot. Keep flame away from silicone molds for prolonged periods to avoid damage.
  • Seal porous inclusions (dried flowers, wood slices, paper) with a light sealer beforehand; moisture is your enemy.
  • Keep your workspace warm and dust-free.
  • Avoid whipping air in with aggressive stirring or vigorous shaking.

Troubleshooting common resin issues

  • Sticky or tacky cure:
    • Likely under-mixed or incorrect ratio. Measure carefully by volume and mix more thoroughly next time.
    • If the top is tacky: a thin re-coat of freshly mixed resin can sometimes fix the surface.
    • If it’s soft throughout: removal may be necessary; cure problems often can’t be salvaged.
  • Excess bubbles:
    • Warm the resin, mix slower, pour thinner, and use brief heat.
    • Check that inclusions are dry and sealed.
    • Ensure your workspace isn’t cold; lower temps = thicker resin.
  • Cloudy resin in bottle (before mixing):
    • Often a cold-weather effect. Warm the sealed bottles in warm water and the cloudiness should clear up. This does not mean the resin is expired.
  • Fisheyes or craters:
    • Usually contamination or oils on the surface. Wipe surfaces with isopropyl alcohol (let dry fully) before pouring.
  • Yellowing over time:
    • All epoxies amber gradually, but UV inhibitors help slow it. Avoid prolonged direct sunlight when possible.

Warm tips and shelf life

The manufacturer notes:

  • Shelf life is approximately 1 year.
  • Cloudiness in the unopened resin can be caused by cold. A gentle warm-water bath typically clears it—this is not expiration.
  • For product questions or issues, reach out to LET’S RESIN for after-sales support.

Store in a temperature-stable place with tightly sealed caps and minimal exposure to humidity.

Safety and best practices

  • Wear nitrile gloves and protect your surfaces.
  • Work in a well-ventilated area.
  • Avoid skin contact and do not ingest. Keep away from pets and children.
  • Do not assume food safety unless the manufacturer explicitly states it. Most craft epoxies are not certified for direct, prolonged food contact. For coasters or décor, it’s fine; for cutting boards or surfaces that contact food regularly, you’ll need an epoxy explicitly rated for incidental/food contact or another finishing method.
  • Clean up uncured drips with isopropyl alcohol or acetone. Once cured, resin is difficult to remove mechanically.

Project ideas to try with this kit

  • Petri-effect coasters with galaxy color schemes
  • Dainty floral pendants with dried baby’s breath
  • Metallic flake earrings and keychains
  • Bookmark molds with mica ribbons and gold leaf
  • Resin-sealed mini canvases with ink swirls
  • Ocean-pour coasters with layered white waves
  • Small wood inlays (seal wood beforehand)
  • Photo charms (laminate or properly seal images first)

What this resin is—and isn’t—ideal for

Great for:

  • Jewelry, small castings, and medium-thin layers
  • Alcohol-ink art and Petri blooms
  • Art topcoats, small wood accents, coasters

Not ideal for:

  • Very deep single pours (e.g., thick river tables); use a deep-pour resin formulated for large masses
  • High-temperature applications (hot pans, trivets). Most craft resins have practical heat limits; use trivets or select a high-temp-rated formula if that’s your goal.

How it compares to other resin options

  • Versus ArtResin (tabletop/art coating):
    • ArtResin is a well-known art-topcoat with strong UV stabilization. LET’S RESIN is typically more budget-friendly and specifically tuned for alcohol inks/Petri techniques. If you primarily do alcohol ink blooms or cast small items, LET’S RESIN offers a strong value.
  • Versus ProMarine Table Top:
    • ProMarine is a popular tabletop finish with a slightly thicker feel in some conditions. LET’S RESIN’s “Bubble Free” craft orientation can feel a touch easier in small molds and jewelry where delicate degassing matters.
  • Versus UV-cure resin:
    • UV resins cure in minutes under UV lamps and are awesome for tiny, quick projects. However, they can be more brittle and may yellow faster. Two-part epoxies like LET’S RESIN typically deliver better durability and long-term clarity, especially with UV inhibitors.
  • Versus deep-pour epoxies:
    • Deep pours are engineered to handle larger volumes and dissipate heat slowly—great for 2–4 inch pours. LET’S RESIN is a general craft resin better suited to thin layers and small-to-medium molds. For river tables or thick blocks, choose a deep-pour specific resin.

FAQs

  • Can I use this in silicone molds?
    • Yes—this kit is excellent for small mold projects. Ensure molds are clean and fully dry.
  • Is it food safe?
    • Unless the product label explicitly states a food-safe certification, assume it is not intended for direct, prolonged food contact. Use it for décor and coasters, not for cutting surfaces or direct-contact utensils.
  • What’s the working time and full cure?
    • Working time and cure depend on temperature, volume, and conditions. Follow the timings on the label. As a general craft guideline, many 1:1 resins offer a workable window in the tens of minutes and a cure across 24–72 hours. Your results will vary with room temp and pour thickness.
  • Will it yellow?
    • Over time, all epoxies yellow somewhat, but this formula includes UV inhibitors to help slow that process. Store finished pieces out of direct sunlight when possible.
  • How do I prevent bubbles?
    • Warm the resin gently, mix slowly, pour in thin layers, use brief heat, and seal porous inclusions.
  • What if my resin arrives cloudy?
    • That can happen in cold weather. Warm the sealed bottles in warm water for a few minutes (not hot), dry, and use as normal.
  • Can I color this resin?
    • Yes—use resin-safe pigments, alcohol inks (especially for Petri effects), mica powders, or dyes made for epoxy. Avoid adding too much liquid colorant, which can impact cure.
