How to Remove Bubbles from Resin Wall Coatings

Q: Best Practices to Avoid Bubbles

Mix slowly: Stir your resin gently and steadily to reduce air incorporation. Apply in thin layers: Thin coats allow bubbles to escape before the resin sets, ensuring a smoother finish. Select the right tools: Using purpose-made application rollers, like the Resin & Paint Application Rollers , helps distribute resin evenly and can further discourage bubble formation on walls. Always work at the recommended room temperature to allow the resin to self-level and bubbles to rise.

Dealing with Bubbles in Resin Wall Coatings

Bubbles appearing in resin wall coatings are a common frustration, but with the right approach, they can be minimised or eliminated for a flawless surface. This guide explains why bubbles form, how to prevent them, and quick solutions if they show up during your project.

Why Do Bubbles Form in Resin?

Bubbles in resin coatings usually occur during the mixing or application process. Fast or vigorous mixing traps air inside the resin, while applying thick layers can also cause bubbles to rise and get trapped before curing. Environmental factors like high humidity or temperature fluctuations can make the issue worse, especially when working on vertical surfaces.

How to Remove Bubbles After Application

If bubbles do appear shortly after application, act quickly but gently before the resin begins to cure. Use a heat gun or hair dryer on a low setting, passing it briefly over the surface to encourage trapped air to rise and pop. Take care not to overheat or scorch the resin or wall surface.

When This Matters Most

Bubbles are particularly noticeable in glossy finishes or when using transparent or clear resin wall coatings, such as Vertical Glass. If a decorative, seamless result is important—such as in kitchens, bathrooms, or feature walls—extra care with bubble prevention and removal will ensure professional-looking results.
