Fixing Bubbles or Runs in New Resin Coating

← Back to How to cover resin tiles?

New resin coatings occasionally develop bubbles or unwanted runs, especially on tiles or vertical surfaces. Here’s how to achieve a smooth, flawless finish every time.

Why Do Bubbles or Runs Occur?

Bubbles in resin often result from mixing, rapid application, or trapped air beneath the surface. Runs are common with fluid resins applied to vertical or uneven tiles, since gravity pulls the coating downwards. Understanding these issues can help you select the right materials and methods.

Techniques for Removing Bubbles and Preventing Runs

• Removing bubbles: As soon as resin is poured, pass a heat gun lightly over the surface. Keep the tool moving to avoid overheating and damaging the finish. This encourages bubbles to rise and disappear, leaving a glassy effect.
• Preventing runs: Choose thicker, non-drip resins especially formulated for vertical tiles or wall coatings. For example, Art Pro epoxy resin has a dense consistency ideal for even coverage without drips.
• Minimise disturbance: Work in a dust-free, draught-free area and ensure your substrate is properly primed.

When This Matters Most

If you’re covering decorative or vertical surfaces, addressing bubbles and runs early is crucial for a presentable, durable finish. Using a resin like Vertical Glass makes application on sloped or upright tiles much simpler by reducing the risk of unsightly drips.
