Creating Stunning Inclusions in Resin Casting Woodworks

Why Use Resin Casting in Woodworking Projects?

Being a synthetic substance with two parts- a resin and a hardener – resin is a versatile material. They mix chemically to create a solid that is clear, stiff, and long-lasting. By modifying resins with colors, dyes, or fillers, woodworkers may express their artistic side and produce breathtaking visual effects.

Enhancing visual appeal

The most exquisite masterpieces may be made while working with wood and resin. The details in the grain of wood may be brought out by applying clear resin, and your creations will truly stand out if you add colored epoxy next to the wooden components. The classic pairing of wood and resin is unmatched. It transforms a decent woodworking project into something amazing. More significantly, it also increases its durability. ·        

Projects combining wood and resin are growing in popularity as more people search for original ways to customize their homes. The applications for resin-based crafts are virtually limitless, ranging from cutting boards to coffee tables. Resins may be used to manufacture everything from jewelry to skateboards, surfboards, bookmarks, and tables to resin/wood cutting boards. It also works well for upcycling old wooden furniture, revitalizing it with a variety of colors and designs. The best aspect is that even inexperienced craftsmen can produce stunning resin-wood creations since resin is a simple material to deal with.

A solid grasp of working with wood is helpful for some tasks. While certain projects might be highly complex and require expensive instruments to complete, others can be more straightforward and still look spectacular.

Strengthening wood structures

Its remarkable endurance is one of the main advantages of using resin in woodworking projects. Craftspeople may shield their wooden works from regular wear and tear, dampness, and scratches by coating them with a layer of resin. For tabletops, counters, and other furniture items that need strong protection without sacrificing their natural beauty, resin is a particularly good choice.

Natural flaws in wood, including voids, cracks, and knots, can take away from the material’s overall visual appeal. Woodworkers can fill in these gaps with ease thanks to resin, which provides a useful solution. Arts and craftspeople may turn imperfections into striking design elements that give their works character and individuality by painstakingly filling holes and fissures with colored resin.

3.1 The Impact of Resin Casting on Woodworking Aesthetics

Creating stunning inclusions

Resin may be used in a multitude of inventive ways in woodworking projects. Because it is versatile and produces eye-catching, impactful effects, resin is becoming more and more popular among artistic artists, craftsmen, and enthusiasts.

When using resin in combination with live edge timber in woodworking, one approach to maximize its benefits is to do so. Here, trees are chopped such that their mostly uncleaned surface retains its inherent imperfections, adding character to objects manufactured from them. A visually striking item may be made by pouring resin over the living edge. This material can be used to build slides for wooden planters, vases, candle holders, or any other imaginative project. 

Resin in a woodworking project can be used in a variety of ways outside of just using it with live edge timber. While it could seem alluring to just pour liquid resin onto objects, it would be more fascinating to add color pigments to the mixture beforehand to produce interesting patterns and effects. To include items into your creation permanently, you may even try embedding them in the wet resin while it’s still curing. Seashells or polymer clay work great for this! Embedding gemstones is another well-liked method that adds appeal and value. This is particularly useful if you intend to sell your creations at markets or online.

Additionally, woodworkers may experiment with complex inlay designs using resin, which improves their level of skill. Craftsmen can add vivid colors, patterns, or even custom designs to their creations by employing resin inlays. Seashells, wood, or gemstones may all be embedded using epoxy resin and carpentry techniques to provide eye-catching focus points and striking visual contrasts.

When it comes to experimenting with resin applications in woodworking, the options are endless, so feel free to explore any and all ideas that occur to you!

Color and texture variations

Resin casting can produce many colorful results. Have you ever been curious about the painting process? To make several hues, use smaller, dry, and clean mixing cups. Transfer a tiny quantity of resin into your smaller cups and mix gently to ensure everything is well combined. Add pigments in lesser increments at first until the desired hue is achieved.

Many resin casting employ various coloring methods. Here are some methods:

Airbrush paint

All paints that are often used in relation to airbrushes or are generally suitable for airbrushing are included in the phrase “airbrush color.” These colors are available as acrylic hues or water-based hues, and they are very water-based.

The coloring pigments in airbrush paints are remarkably liquid in their carrier media and extremely finely ordered, in contrast to conventional acrylic or water-based paints. Airbrush paints are frequently used to color casting resins since they are also easy to mix and have a high brightness.

The cost of this resin casting coloration is the primary issue. It’s can really be pricey. However, casting resins can be utilized with color powder.

The casting resins can also be colored effectively using pure pigment powder. In any case, before adding the hardener, mix the color powder with the resin throwing pitch. When using pure pigments, a base measurement is usually sufficient.

You may get pigments in any conceivable kind. You will find every color imaginable, ranging from plain tones to shiny, shimmering colors.

Alcohol-based inks

Due to their high concentration and great amount of coloring pigment, alcohol-based inks can be minimally dosed into casting resins. Usually, a few drops will be sufficient to tint the casting resin. However, this quantity also applies to inks on water premises in addition to those on liquor premises. Every coloring technique for resin casting must be used with extreme caution. 

Exercise caution to avoid ruining the entire project. Using the appropriate tools will guarantee that your resin castings turn out as good as possible.

4. Tools and Materials Needed for Resin Casting

The adage “use the right tools for the job” holds true when it comes to dealing with resin. Since each resin tool has a distinct function, it’s critical to utilize the right ones for the job to save time, money, and effort.

Tools and Materials

Casting resin

In molds, they cure clear and durable. Bubbles are easily released by casting resins. That is crucial if you are pouring thick layers or big amounts of resin all at once.

When applied in a mold, any resin that mixes thick enough to form a coating will produce microbubbles.  Furthermore, bubbles are the terrible enemy of resin crafts.

Mixing cups 

It is essential to measure resin pieces accurately. If not, it might not solidify. Cups for mixing might be useful here. To get exact proportions for the resin and hardener, resin mixing cups are equipped with lines.

Stirring Utensils

Using plastic stir paddles is an excellent method for fully mixing your resin. You may use them again because they are durable and easy to clean.  To guarantee that your resin cures without any sticky places, thorough mixing is necessary. One of the main causes of sticky resin is insufficient mixing.

Safety equipment 

Safety glasses and gloves are essential for your health. Because they are chemicals, resins must be handled carefully.

Level surface for casting 

When lying on the floor, make sure your workspace is level and flat. If you fill your molds with resin, you don’t want to discover later that the cure is uneven.

Wax paper, freezer paper, or protective tarp 

When resin casting, it is difficult to avoid having resin leak or spill anywhere. You may allow spilled resin on the surface to cure by covering your work area with anything having a waxy surface. When it’s solid, pull it off. Given how affordable these materials are often, you could even opt to toss it out.

Resin mold

Among the resin supply list, this is the most enjoyable. Using this tool is a lot of fun, whether you’re molding jewelry, coasters, or something else entirely. An open mold with minimal detail will be the simplest to use for novices.  

Mold release 

This aids in the resin castings’ release from the molds. The life of resin molds is further extended via mold release. Popping and twisting can cause microtears that shorten the mold’s life or distort the mold. Having it is also beneficial in case something goes wrong.

Molds and mold-making materials

Sellotape or brown tape

Using brown or sellotape is the most straightforward way to create your own mold. These may be used to draw the contour of a form on top of boards, creating a dammed region into which you can pour resin.

The tape and board may be taken out from underneath the item once it has completely dried. Making sure your tape is sealed tightly and doesn’t leave any gaps is what you should watch out for in this situation; you might want to stack it up to be sure.

The drawback of utilizing tape is that it can be quite challenging to use it to create the precise form you want. This might imply that more sanding will be required once your piece has dried in order to get the desired finish.

PVC sheet material 

Transparent PVC sheet, which doesn’t have to be extremely thick, is another material that may be used to create a mold. With a knife or pair of scissors, this may be readily cut to the desired shape and proportion. After that, secure the parts together with sellotape. Verify that the mold is not missing any spaces. Next, add the resin and allow it to cure, adhering to the mixing, pouring, and curing time recommendations provided by the resin manufacturer.


Silicone is one of the greatest materials to use for molds since resin doesn’t attach to it very well and it’s quite flexible, making it reasonably easy to remove your resin after it’s completely set. You may buy silicone molds online or make your own at home. Given that they are reusable, their prices can be really fair. 

Predetermined forms can be achieved by pouring natural and synthetic resins into silicone molds, which are usually composed of flexible rubber. Resin molds can be used to create lightweight jewelry pieces, parts for manufacturing, and parts that resemble plastic. The most adaptable mold is silicone as it doesn’t need a separating agent to stop resin from sticking to it.

With silicone molds, pyramids, coasters, and sculptures can be casted. Silicone molds can be purchased in a wide variety of forms and designs. 

Other materials

Additional materials for resin molds include of latex, gypsum, metal, and glass fiber. 

Rigid mold materials, including plaster, glass fiber, metal, and wood, are difficult to warp when reused, whereas softer mold materials, such silicon and soft rubber, are simpler to pop up completed resin sheets.

Investing in a releasing agent is worthwhile for all molds. This will make it easier to remove and stick less while de-molding the job. Larger projects benefit greatly from this, since it reduces the possibility of harming the mold or the product itself.

Use three-dimensional (3D) items to give the resin mold its form while making one. We refer to this item as a model. To create intricate resin molds, set the model inside a container and cover it with clear rubber. The rubber may be divided into two pieces once it has dried, each of which can serve as a mold for producing half of the resin block.

Soft resin molds can occasionally distort with frequent usage. Spare molds are stiffer molds that are used to support rubber molds that are flexible while resin is being cast. The backup rubber mold can stop the primary rubber mold from deforming when casting resin is introduced. These molds can be composed of fiberglass, gypsum, or occasionally wood.

Cast resin is put into the resin mold to cure after the mold has been made and the spacer has been placed. The majority of resin molds may be reused several times to create almost identical resin blocks; this helps to reduce distortion, especially when extra molds are employed. To alter the final product’s color, colorants can be applied to remove the resin. Transparent resin can suspend and encapsulate tiny items or additives if they are applied during the casting process.

Before using the silicone molds again, they must be completely cleaned to get rid of any leftover resin mixture. Should any residue or hardened resin remain on the mold, it will adhere to the freshly created piece during subsequent usage. This might make your new project fail. Thus, carefully clean the mold after each usage, let it dry, and then use it again. If there is any residual moisture on the mold, it might potentially endanger the following job. Next, ensure sure the molds are kept dry and clean by storing them in an airtight container.

4.1 Specialized Tools for Advanced Resin Casting Techniques

Pressure pots

For resin castings that are free of air traps and bubbles, a pressure pot is necessary. This is particularly important when making transparent resin casts since trapped air can distort the look of a casting that is perfectly clear. Resin may be forced into thin parts of a mold and air can be forced out of it using a pressure pot. By doing this, air traps and bubbles in the cured castings are removed. All the additional fittings and a gauge are included with this pressure pot. 

The finest method for producing resin castings of superior quality is casting under pressure. This is particularly valid for intricate molds and challenging recesses. Pressure casting produces a nearly bubble-free casting by compressing air to sizes that are invisible to humans.

Vacuum chambers

For any professional resin artist, a vacuum chamber—also referred to as a vacuum pot for resin, a resin vacuum chamber, or a vacuum degassing chamber for resin—is an indispensable instrument. Its main function is to eliminate air bubbles from resin before to the curing process, guaranteeing your finished work will have a smooth, transparent surface. The way this gadget operates is by applying a regulated suction to the resin. As a result, the air bubbles rise to the surface and leave, leaving your resin flawless and professional-looking.

Vacuum chamber use for resin is very simple. First, fill the cup that is given with your blended resin. Make sure the cup has adequate room for the resin to expand throughout the degassing process. The cup should then be gently placed into the vacuum chamber and sealed tightly.

After everything is ready, activate the vacuum chamber and watch the magic begin. You will be able to see the air bubbles explode and rise to the surface as the machine creates a vacuum. Your resin comes out perfectly bubble-free from the procedure.

Depending on the kind and volume of resin, there may be a different suggested length of time to keep it in the vacuum chamber, but for me, it’s usually between 9 and 14 minutes.
