How to Resin a Large Piece of Art?

May 22, 2024

Take a moment to imagine a beautiful work of art, not just painted on a canvas but transformed by a layer of crystal-clear resin. This is the magic of resin art on a grand scale. Resin, typically a synthetic epoxy, becomes an excellent artistic element when applied to large pieces.  The result? A breathtaking fusion of texture, depth, and a high-gloss finish that elevates the artwork to a whole new level.

This technique isn't just about aesthetics. The resin is known to act as a protective layer, shielding your projects from dust, scratches, and even UV damage, ensuring its beauty endures for years to come. In this blog, we will guide you through the process of resin coating a large piece of art, from preparation to finishing touches. Applying resin to a large piece of art requires more consideration than smaller pieces. With practice and exploration, you can make incredible art pieces! Many resin art workshops are available to help you on your creative journey.

Preparation is Key

When using resin for a large piece of art, preparation is key. Here's a breakdown of the crucial prep steps to ensure a smooth and successful application:

  • Wood is King: For large artworks, ditch the canvas and opt for a sturdy wooden panel. Canvas can warp under the weight of the resin, potentially ruining your piece. Wood provides a stable and reliable base.
  • Panel Prep: Ensure your panel is clean, dry, and free of dust and dirt. You can wipe it down with a moist cloth followed by a light sanding to create a slightly textured surface for better resin adhesion.
  • Leak Prevention: Remember to consider the sneaky drips of resin! Use painter's tape to create a tight seal around the back edges of the panel. This prevents drips from seeping through and ruining the backside of your artwork.
  • Size Matters: When choosing your panel, consider the weight of the cured resin. Opt for a thick panel that can support the weight of the resin without warping.

[Pro Tip: Level Up: Ensure your panel is perfectly level for a flawless finish. Use a spirit level to check and adjust if necessary. A level surface allows for even resin distribution and prevents pooling in unwanted areas.]

These preparation steps will create a solid foundation for your large-scale resin art masterpiece. Remember, a well-prepped surface is essential for a flawless final product.

Steps to Resin a Large Piece of Art

Transforming your large artwork with resin adds depth and a glossy finish. But with a bigger canvas comes bigger considerations. Here's a breakdown of the process to ensure a successful outcome:

Resin Application

  • Mixing in Batches: Mix the resin in smaller batches for large areas. This prevents premature curing before application. Consider using a drill attachment for thorough mixing of larger quantities.
  • Pouring Technique: Slowly and evenly pour or spread the resin across the artwork. Use tools like squeegees or pouring cups for better control and even distribution.

Dealing with Bubbles

  • Torch Time: A propane torch can be your friend for removing bubbles that rise to the surface. Caution is key! Keep a safe distance to avoid harming the artwork with heat.

Additional Tips

  • Work in Stages: Consider pouring the resin in sections for very large pieces. This ensures proper coverage and prevents the resin from setting too quickly.
  • Extra Hands: Especially in hot weather (which accelerates curing), having an extra person to help pour and spread the resin is beneficial.
  • Curing and Dust Protection: Once applied, monitor the curing process for the first hour. After curing, use a large cardboard box to protect the artwork from dust.

Things to Avoid While Applying Resin to a Large Piece

When working with resin on a large scale, avoiding certain pitfalls is crucial for a successful outcome. Here's what to watch out for:

Improper Mixing

  • Inaccurate Measurements: Inaccurate resin-to-hardener ratios can disrupt curing, leaving your resin sticky or uncured.
  • Under-Mixing: Unevenly mixed resin can lead to cloudy patches or uncured areas. Scrape your mixing container for a thorough mix.
  • Temperature Troubles:  Resin has ideal curing temperature ranges. Working in very cold or hot environments can affect curing times or cause the resin to become too thick for proper application.

Air Bubbles

  • Pouring Too Quickly: Rushing the pour can trap air bubbles within the resin. Pour slowly and steadily to allow air to escape.
  • Improper Tool Use: Using tools with rough edges or improper pouring techniques can introduce air bubbles. Opt for smooth tools and pouring cups designed for resin application.

Resin Depth Mishap

  • Applying Too Much Resin: For large pieces, resist the urge to use a massive amount of resin at once. A deep resin layer can take a long time to cure and may even generate excessive heat, leading to cracking. Consider pouring the resin in sections for better control and cure time.

A Dusty Disaster

Dust settling on the wet resin can create imperfections. Work in a clean, dust-free environment and cover your workspace if necessary.

Benefits of Using Resin on a Large Piece of Art

Resin can offer several advantages for large-scale artworks:

  • Durability: Resin creates a hard, protective layer that shields your artwork from scratches, dents, and moisture. This is especially important for large pieces that are more prone to accidental bumps or spills.
  • UV Resistance: High-quality resin offers protection from UV rays, which can cause fading over time. This is crucial for preserving the vibrancy of your artwork, particularly if it's displayed in a well-lit area.
  • High Gloss Finish: Resin creates a beautiful, glossy finish that enhances the colours and depth of your artwork. This can make a real statement piece, especially on a large scale.
  • Crystal Clear: Clear resin allows the artwork beneath to shine flawlessly without distortion or clouding.
  • Self-Levelling: Resin can self-level to a smooth, even surface, ideal for achieving a polished look on a large piece.
  • Embellishments: Resin can embed various objects within the artwork, adding a unique 3D element to your large-scale creation.


Resin coating a large piece of art can seem daunting, but it can be rewarding and fulfilling with the right tools and techniques. Following the steps summarised in this blog, you can achieve a professional-looking finish that will enhance and protect your artwork for years.
