50 tips for using UV resin in your crafts

Here are 30 tips for using UV resin, for crafting! Gone are the days of waiting 24 hours for resin to cure, UV is so much easier and faster. BUT it’s only great for small projects.

That’s why it is UV resin crafting is popular for jewelry making, charms, keychains, and mixed media projects because it cures quickly and creates a glossy finish.

First off, use a good brand. I really like Let’s Resin. This is not sponsored, I’m sharing my faves! This is the kit I started with and I still use it faithfully.

Whether you’re brand new to UV resin or refining your technique, these tips will help you avoid common mistakes and create professional-looking pieces.

Essential tools: 

• A UV lamp is essential for curing resin quickly and evenly. Choose one with sufficient wattage to fully cure layers without leaving sticky spots.
• Silicone molds or silicone mats are important because UV resin does not permanently stick to silicone, making cleanup easy and results smoother.
• Disposable gloves protect your hands from sticky resin and prevent fingerprints from forming on finished pieces.
• Precision applicators such as squeeze bottles, toothpicks, or fine-tip tools help control resin placement and remove bubbles from small areas.
• Isopropyl alcohol wipes are necessary for cleaning tools, surfaces, and accidental spills before the resin cures.

Overall tips

• Use thin layers of UV resin for proper curing. Thick pours can remain sticky or soft inside, even if the surface appears cured.
• Cure each layer completely before adding the next. Layering too soon can trap uncured resin underneath and cause cloudiness or flexibility.
• Work under a dust cover whenever possible. Dust, lint, and pet hair are common issues with UV resin, and a simple plastic container works well.
• Protect your workspace with a silicone mat. UV resin sticks to most surfaces but peels cleanly from silicone.
• Test your UV lamp strength regularly. Weak lamps lead to under-cured resin, so replace bulbs or upgrade your lamp if curing times increase.
• You can place items in direct sunlight to give them a nice final cure.

NOTE: DO NOT use UV resin for heavy coats or casting, etc. UV resin is best for smaller projects.

How to prevent bubbles in uv resin

• Slightly warm the resin before use to improve flow and reduce bubbles. Placing the bottle in warm water for a few minutes is usually enough.
• Use a toothpick or needle to pop surface bubbles before curing, especially in detailed areas.
• Avoid shaking resin bottles. Shaking introduces bubbles that are difficult to remove later.
• Cure resin in short bursts rather than one long cycle. This helps prevent bubbles and overheating.
• Let resin rest briefly before curing. Allowing it to settle gives bubbles time to rise naturally.

Curing your resin

• Use clear or transparent molds so UV light can pass through evenly and cure the resin properly.
• Flip pieces and cure the back side (while still in the mold) to ensure full hardness and prevent soft spots.
• Avoid overfilling molds. Overfilled molds can leak and cause uneven edges.
• Cure small details separately when possible. Tiny embellishments cure more evenly when handled on their own.
• Allow pieces to cool between curing cycles. Excess heat can cause warping or cloudiness.

Take care of your UV resin supplies

• Wear gloves to prevent fingerprints and direct skin contact. UV resin can be irritating and leaves marks that are hard to remove.
• Store UV resin away from sunlight. Natural light can cause resin to cure inside the bottle.
• Keep bottles tightly sealed when not in use to prevent thickening and contamination.
• Clean tools immediately using alcohol wipes. Once cured, UV resin is difficult to remove.
• Maintain a dedicated UV resin tool kit to avoid cross-contamination with other craft supplies.

UV resin finishing and design tips

• Cure clear base layers before adding inclusions. This helps embed items cleanly and prevents floating.
• Check pigment and glitter compatibility before mixing. Some additives can interfere with curing.
• Use pigments sparingly. Too much colorant can leave resin soft or tacky.
• Lightly sand surfaces before adding a topcoat to help new layers adhere better.
• Finish pieces with a glossy UV resin topcoat to enhance shine and durability.

Beginner UV resin mistakes to avoid

• Avoid embedding porous materials without sealing them first. Paper, fabric, and wood should be sealed to prevent bubbles.
• Always test new supplies on scrap molds. Different brands of resin, pigments, and molds can behave differently.
• Don’t rush the curing process. Patience produces stronger, clearer results.
• Practice with simple projects before attempting complex layered designs.
• Work on a flat and even surface.

How to clean up UV resin

• Wipe spills immediately with alcohol wipes. UV resin is easiest to remove before it cures, and isopropyl alcohol works best on tools and work surfaces.
• Peel cured resin off silicone mats once it has fully hardened. Silicone allows cured resin to lift cleanly without scraping or damage.
• Use painter’s tape or packing tape to lift sticky residue. Press the tape onto tacky areas to remove uncured resin without spreading it.
• Clean tools before curing by wiping brushes, mixing sticks, and tweezers right after use. Once UV resin hardens, it becomes difficult to remove.
• Cure paper towels, gloves, or disposable items under a UV lamp before discarding them. This prevents leaks and keeps uncured resin from making a mess in the trash.

Unexpected ways to use UV resin

• Use UV resin to repair tiny chips in ceramics or pottery. A small dot of UV resin can fill a chip, smooth the surface, and seal it so it doesn’t worsen. Once cured, it adds strength and a subtle gloss that blends in beautifully. DO NOT use where your mouth would be – like on a mug rim.
• Seal embroidery knots or thread ends on mixed media pieces. A micro-drop of UV resin on the back of embroidery or stitched art keeps threads from unraveling without adding bulk like glue.
• Create raised details on paper, labels, or artwork. UV resin can act like a dimensional accent for lettering, line art, or illustrations, adding texture and shine where you’d normally use puff paint or embossing. Add drops with glitter mixed in, and cure on a silicone mat, and peel off. So cool!
• Reinforce fragile jewelry connections. Apply UV resin to wire-wrapped joins, jump rings, or delicate attachment points to lock them in place and prevent wear over time.
• Fix peeling stickers, decals, or vinyl edges. A thin layer of UV resin can reseal lifting edges on mugs, notebooks, or craft tools, protecting the design and extending its life.
