5 Ways to Achieve a Thick Layer of Resin Like a Pro

Resin art is a captivating art form that allows you to create lovely works with a glossy, high-quality finish. But what if you desire a thick resin layer for a more dramatic effect? While thicker pours can be trickier, there are ways to achieve them successfully. Enrol in a resin art workshop if you’re still worried about your creative skills. 

5 Ways to Achieve a Thick Layer of Resin 

Here are five methods to help you get that gloriously thick coat of resin:

1. The Layering Approach (24-Hour Method)

This method is perfect for situations where you want to build up the resin thickness gradually or incorporate embellishments between layers. Begin by pouring your first layer as usual and letting it cure for 24 hours. Once completely cured, the surface shouldn't feel sticky or soft. Now comes a crucial step: sanding. Use coarse sandpaper (around 80 grit) to roughen the cured resin surface. This creates a "tooth" for the new layer to adhere to, preventing delamination. Wipe away any sanding dust, and then you're ready to pour your next layer!

Pro Tip: Lightly sand the cured surface to create a "tooth" for the next layer to adhere better.

2. The Faster Layering Approach (3-5 Hour Method)

If you need more time, this method offers a quicker way to achieve multiple layers. Pour your first layer and wait 3-5 hours until it reaches a gel-like stage. This is your window to add desired objects before pouring the next layer. Remember, thicker layers take longer to cure completely, so plan accordingly.

Pro Tip: Monitor the first layer's cure time closely. Don't wait too long, or the layers won't bond properly.

3. The Warm Water Bath Technique

This method involves warming the sealed resin bottles in a warm water bath. Contrary to what you might expect, warm resin has a lower viscosity, making it thinner and more accessible to pour in slightly thicker layers (up to ¼ inch). The benefit? Less bubble formation! However, be mindful that heat accelerates curing, so you'll have less working time with the mixed resin. Ensure everything is prepped before pouring, and be cautious not to overheat the resin, as it can cure prematurely.

Pro Tip: Ensure the water temperature stays warm but not too hot (think baby bath temperature).

4. Choosing the Right Resin

Some resin formulas are naturally thicker than others. Look for brands designed explicitly for thicker pours. These resins often have a longer working time to accommodate the slower flow rate.

Pro Tip: Always follow the specific instructions and safety precautions for casting resin.

5. Mould Matters

When working with thicker resin layers, using a mould is highly recommended. Moulds provide a contained space for the resin, minimising the risk of spills and leaks. Opt for silicone moulds, known for their flexibility and ease of demolding.

Pro Tip: Regardless of the method, always ensure proper ventilation when working with resin. Wear gloves, eye protection, and a respirator for safety.

Safety First!

Remember, the resin can be hazardous. Always work in a well-ventilated area, wear gloves and protection glasses, and carefully review the manufacturer's instructions.

With these tips and techniques, you'll be well on your way to creating stunning resin art with thick, luxurious layers that will leave a lasting impression.

Why a Thick Layer of Resin Matters?

Here's why a thick layer of resin can take your project to the next level:

  • Empowering Embellishments: Thick resin allows you to embed larger objects and create a more dimensional piece. Imagine a crystal clear layer showcasing a delicate flower or a captivating seashell suspended in mid-air.
  • Creating Depth and Mystery: A deeper layer increases the optical play of light within the resin. You can achieve an almost water-like quality, where light seems to dance through the piece. This adds intrigue and makes the viewer want to explore the depths of your creation.
  • Building a Sturdy Base for Artful Add-Ons: For techniques like resin geode art or layered resin pours with paint, a thicker base provides a strong foundation for subsequent layers. This allows you to build up a more complex and visually exciting artwork.

Of course, achieving that perfect thick pour requires some extra care:

  • Bubble Battles: The enemy of thick resin is trapped air bubbles. To avoid an unwanted cloudy effect, pour using a technique that allows air bubbles to escape or use a heat gun to coax them out gently.
  • Heat Hazard: Thicker layers cure slower and can generate more heat. Use a resin formulated explicitly for thicker pours to avoid cracking or warping.
  • Layer by Layer: Sometimes, achieving the desired thickness requires multiple pours. Research techniques like the "partial cure method" ensure proper layer bonding.

So, when should you reach for the extra resin?

  • Encasing Objects: A thicker layer must fully encapsulate your chosen inclusions to preserve a unique souvenir or create a three-dimensional art piece.
  • Profound Dive Effects:  For projects where you want to create a sense of depth and explore the interplay of light within the resin, a thicker pour is the way to go.
  • Building a Canvas:  When using resin as a base for other artistic mediums like pigments or alcohol inks, a thicker layer provides a sturdy platform for creativity.

Ultimately, the best resin thickness depends on your project's specific needs. But don't be afraid to experiment with thicker pours! With some planning and the proper technique, you can unlock a new world of innovative possibilities in your resin art.


A thick resin layer can add depth and dimension to your resin art projects. By choosing the suitable resin, using the proper techniques, and allowing for adequate cure time, you can make stunning works that showcase the magnificence of a thick resin layer. Experiment with different methods and materials to find the best approach for your projects, and watch as your creations come to life with a luxurious, thick layer of resin.  If you are ready to explore your skills, visit the Arts Shala website and get a chance to turn your passion into profit.
