Does Epoxy Stick to Starboard? | All You Need to Know

However, when it comes to it’s compatibility with specific materials, one might wonder whether it can effectively adhere to Starboard. Starboard, a popular marine-grade polymer, is widely utilized in multiple marine and outdoor applications due to it’s exceptional durability and resistance to harsh weather conditions. To determine whether epoxy can stick to Starboard, one must delve into the chemical composition and surface characteristics of this robust synthetic material, and explore potential surface preparation techniques that might facilitate a successful epoxy bond.

Does Epoxy Stick to Plastic?

When it comes to the question of whether epoxy sticks to plastic, the answer is a resounding no. Plastic items such as cups, bowls, and Tupperware are ideal surfaces for working with epoxy because they don’t bond with it. This characteristic of plastic makes it easy to work with epoxy in various applications. Whether you’re creating artistic pieces or repairing broken plastic items, epoxy can be used without worrying about it sticking to the surface.

It allows for easy release of the epoxy from the plastic surface, ensuring a clean and smooth finish. Whether you’re casting intricate designs or embedding objects into epoxy, plastic provides a convenient and hassle-free surface to work with. This makes it a favorite choice among craftsmen and DIY enthusiasts alike.

This not only saves you money, but it also makes the process of working with epoxy more sustainable and environmentally friendly.

Tips for Using Epoxy on Plastic Surfaces

  • Make sure the plastic surface is clean and free of any dirt or grease before applying epoxy.
  • Use sandpaper to lightly roughen the plastic surface, which will help the epoxy adhere better.
  • Apply a thin layer of epoxy onto the plastic using a brush or applicator.
  • Allow the epoxy to dry completely before applying any additional coats.
  • If necessary, apply multiple thin coats of epoxy rather than one thick coat for better adhesion.
  • Be mindful of the temperature and humidity conditions when applying epoxy on plastic surfaces as it can affect the curing process.
  • Avoid applying epoxy on flexible or highly bendable plastic surfaces as it may crack or peel over time.
  • Consider using a primer designed specifically for bonding epoxy to plastic surfaces for better results.
  • Follow the instructions provided by the epoxy manufacturer for the best application and curing techniques.
  • Always wear protective gloves and work in a well-ventilated area when handling epoxy.

When working with epoxy resin, one common concern is preventing it from sticking to the mold. To address this issue, a simple yet effective solution is to use Vaseline as a mold release. By applying a thin layer of Vaseline over the mold before adding the epoxy resin, you can create a barrier that prevents the resin from sticking. This ensures a smooth and effortless release of the resin from it’s mold.

Will Vaseline Prevent Epoxy From Sticking?

When working with epoxy resin, it’s often crucial to find ways to prevent it from sticking to molds or surfaces. One effective method is to use Vaseline as a mold release agent. By applying a thin layer of Vaseline over the mold before adding the epoxy resin, you create a barrier that prevents the resin from adhering to the mold.

Make sure to cover all areas that will come into contact with the epoxy resin. Remember, if you apply too much Vaseline, it may interfere with the resins ability to cure properly.

Some crafters and professionals prefer using specialized mold release sprays or powders specifically designed for epoxy resin.

Step-by-Step Guide on Using Specialized Mold Release Sprays or Powders for Epoxy Resin

  • Choose the right mold release spray or powder for your specific epoxy resin.
  • Read and follow the instructions provided by the manufacturer.
  • Clean and prepare your mold surface before applying the mold release.
  • Shake the mold release spray bottle well to ensure proper mixing of the ingredients.
  • Spray a thin and even coat of the mold release onto the textured or smooth mold surface.
  • Make sure to cover the entire mold surface, paying attention to any intricate details or corners.
  • If using mold release powder, apply a small amount to a clean and dry cloth or brush.
  • Gently dust the powder onto the mold surface, ensuring even coverage.
  • Allow the mold release to dry completely before pouring the epoxy resin into the mold.
  • Follow the recommended curing time for your epoxy resin before removing the cured piece from the mold.
  • Carefully release the cured piece from the mold by applying gentle pressure or using a release tool if necessary.
  • Clean and store your mold release spray or powder according to the manufacturer’s instructions for future use.

Source: What Is The Best Release Agent For Epoxy Resin?

When it comes to adhering epoxy to StarBoard, there are a few options available. While mechanically fastening or welding King StarBoard is typically the preferred method, there are instances where an adhesive is necessary. In such cases, Lord 7542-AB, 3M’s Scotch-Weld DP-8005, or Chem-Setâ„¢ 6105 Polyolefin Bonder can be used effectively. These products provide a reliable bond with StarBoard, ensuring a secure and lasting attachment.

What Epoxy Will Stick to StarBoard?

When it comes to finding the right adhesive for sticking to StarBoard, the preferred method is to mechanically fasten or weld it. However, in cases where an adhesive is necessary, there are a few options available. One product that works well is Lord 7542-AB, which provides a strong bond with StarBoard. Another option is 3Ms Scotch-Weld DP-8005, a reliable adhesive known for it’s durability and compatibility with various materials.

For those looking for an alternative, Chem-Setâ„¢ 6105 Polyolefin Bonder is also an effective choice. It’s specifically designed to bond polyolefin plastics like StarBoard. This adhesive offers excellent adhesion and is formulated to provide long-lasting results.

Before applying any adhesive, it’s essential to ensure the surfaces are clean and free from any debris or contaminants. This will enhance the adhesion and ensure a secure bond. It’s recommended to follow the manufacturers instructions for proper application and curing time for the adhesive chosen.

This provides a stronger and more reliable bond, especially in high-stress applications or outdoor environments where exposure to harsh conditions is a concern.


While Starboard is generally a low-surface energy material that can present challenges for adhesion, the use of proper surface preparation techniques, primers, and specific epoxy formulations can enhance the bonding capabilities. It’s important to note that individual experiences may vary, and it’s always recommended to consult with manufacturers' guidelines and carry out small-scale tests before committing to a large-scale project. Ultimately, finding the most effective solution for bonding epoxy to Starboard will require a combination of knowledge, expertise, and a willingness to adapt to the unique characteristics of the materials at hand.
