How Can I Minimise Bubbles in My Sink Resin Coating?

Bubbles in resin coatings can spoil the flawless finish you want for your resin sink. With careful preparation and the right techniques, you can achieve a clear, professional result.

Mixing Resin to Reduce Bubbles

Ensuring the resin and hardener are thoroughly mixed is critical. Stir slowly and consistently, scraping the sides and bottom of your mixing container. Vigorous or rushed mixing can introduce air, which then forms bubbles. If possible, use a container with a wide base to allow for easier mixing and less turbulence.

Techniques for Releasing Trapped Air

Once poured, you may notice surface bubbles rising as the resin settles. Using a heat gun or torch, carefully pass the device over the surface in a sweeping motion a few centimetres above the resin. The gentle warmth helps pop bubbles before the resin begins to cure, resulting in a clearer finish.

Practical Coating Tips for Sinks

Coat your sink in a dust-free, sheltered space for the best results. Choose a self-levelling resin such as Art Pro for even surfaces and easier bubble release. Apply the coating in layers suitable for your chosen product’s recommended thickness, avoiding overly deep pours at once. Always wear gloves and follow the instructions included with your resin kit.
