Aleene’s Spray Acrylic Sealer, Gloss Finish
Aleene’s Spray Acrylic Sealer provides a clear, glossy topcoat that protects crafts and art projects. This aerosol finish dries quickly and is designed to resist yellowing with age, making it suitable for indoor and some sheltered outdoor uses. It is best for projects that benefit from a shiny, protective layer without adding significant texture.
Best for: Crafters seeking a fast-drying, high-gloss sealant for paper, fabric, wood, or lightweight plaster items. It’s particularly useful when you want a bright, glassy look and a protective coating that won’t obscure fine details.
Why selected: Its non-yellowing, fast-drying formula helps preserve color and clarity, making it versatile for mixed-media art and home decor projects.
Caution: Use in a well-ventilated area and avoid over-application to prevent drips or optically cloudy spots on delicate surfaces.
Counter Culture DIY Quick Coat Clear Resin Sealer 4 oz
Quick Coat is a clear, VOC-free sealer designed to prep surfaces for the next resin layer. It seals glitter, decals, vinyl, and paint, creating a stable base that helps prevent fisheyes and ensures a crystal-clear finish when resin is applied. It’s a practical first step for many resin art projects.
Best for: Resin artists working on small projects like jewelry, keychains, tumblers, or signs that require a reliable, non-yellowing base before pouring resin.
Why selected: The sealer’s multi-surface compatibility (glitter, vinyl, decals) plus its non-yellowing formula makes it ideal as a preparatory layer before resin pours.
Caution: Apply evenly and fully dry before resin to avoid surface lumps or adhesion issues in high-gloss pours.
Counter Culture DIY Quick Coat Clear Resin Sealer 8 oz
This 8-ounce Quick Coat expands on the 4-ounce version, offering a larger surface area for sealing before resin pours. The VOC-free, clear, non-yellowing sealer provides a smooth base layer to prevent movement of art pieces and ensures a pristine, glass-clear resin finish after pouring.
Best for: Medium-to-large resin projects that require a robust base coat before resin application, helping keep artwork in place and preventing surface imperfections.
Why selected: The larger size increases workflow efficiency for ongoing projects, while maintaining the same protective, crystal-clear results.
Caution: Ensure full dry time before resin application to avoid trapped moisture or surface tackiness under thick coats.

This two-part epoxy system penetrates and seals wood, providing rot resistance and a stable base for further coatings. It is especially suited for outdoor wood, marine applications, and wood restoration projects. The sealer hardens and stabilizes, helping finishes adhere better and last longer.
Best for: Wooden boats, rotted wood repairs, exterior wood projects, and areas requiring durable protection against moisture and wear.
Why selected: It combines penetrating sealing with rot control, offering a robust solution when wood integrity is a concern.
Caution: Follow mixing instructions carefully and ensure proper ventilation due to epoxy components.

Why selected: The kit’s anti-yellowing formula and self-leveling features help produce a professional-looking, durable finish across a variety of applications.

Buying Guide
What should you consider when choosing a sealer for epoxy resin?
- Surface compatibility: Confirm the sealer works with your substrate (wood, metal, plastic, fabric) and with epoxy resin.
- Gloss level: Decide between gloss, semi-gloss, or matte finishes based on the look you want for your project.
- Drying time: Faster-drying formulas save time but may require careful handling to avoid rush mistakes.
- VOC content: Lower VOCs are better for indoor use and indoor air quality; some sealers are VOC-free.
- Protection scope: Some sealers are ideal as base layers, others provide topcoat protection; consider whether you need a penetrating sealant or a surface sealant.
- Color stability: Anti-yellowing formulations help preserve color clarity in UV exposure scenarios.
- Project size: Larger projects may benefit from bigger containers to minimize reordering and seam issues.

Frequently Asked Questions
- What is the difference between a sealant and a topcoat for epoxy resin?
– A sealant primes and protects the surface before resin, while a topcoat protects the finished resin surface from scratches and UV damage. - Do these sealers yellow over time?
– Some are labeled non-yellowing or anti-yellowing; read the product description to confirm long-term color stability. - Can I use a spray sealer on epoxy resin projects?
– Yes, spray sealers can be effective for clear coats on crafts, but ensure compatibility with epoxy without trapping moisture. - Is a water-based or solvent-based sealer better for resin projects?
– VOC-free or water-based options are generally safer for indoor use, but always follow manufacturer guidance for resin compatibility. - How do I choose between a small 4 oz and a larger 8 oz sealer?
– Consider project size, frequency of use, and whether you need to cover multiple surfaces in one session. - Should I seal wood before resin on a boat or outdoor project?
– For outdoor wood or boat restorations, a penetrating sealer that resists moisture is often beneficial before resin.
