How to Fix Bubbles or Dust in a Resin Wall

What Should I Do If There Are Bubbles or Dust in My Resin Wall?

Perfecting a resin wall finish means managing unwanted bubbles and dust that can settle during application and curing. Here’s how to achieve a pristine result every time.

Removing Bubbles for a Smooth Finish

Bubbles are a common concern when working with resin on vertical walls. To avoid them marring your surface, use a heat gun immediately after applying the resin. Hold the tool a short distance from the resin and move it in a sweeping motion. This encourages trapped air to rise and pop, producing a glassy surface. Techniques may vary depending on the resin’s viscosity, so always follow the manufacturer’s guidance for your chosen product. Vertical Glass – Thick Resin Decorative Wall Coating is formulated for vertical applications and responds well to careful heat gun use.

Preventing & Managing Dust During Curing

Dust can quickly undermine the clarity of your resin wall. Once the resin is applied and levelled, cover the area with a protective barrier such as a clean plastic sheet or dust canopy. This reduces airborne particles settling on the surface as the resin cures. In cases where a little dust does appear, a light sanding after full curing can help restore smoothness. Products like Art Pro Deluxe, which are suitable for vertical surfaces, also cure to a sandable finish.

When This Matters

Dealing with bubbles and dust is particularly important for feature walls, decorative panels, or installations in kitchens and bathrooms, where appearance and hygiene are paramount. Taking steps to eliminate these imperfections is key to a flawless, professional result.
