Troubleshooting Bubbles or Dust in Resin Wall Finish

← Back to How can I apply resin to a wall?

Even with careful application, bubbles or dust can occasionally mar your resin wall finish. Understanding how to rectify and prevent these common issues helps you achieve a flawless, professional result.

Addressing Bubbles in Fresh Resin

Bubbles often form as a result of mixing or pouring the resin. Shortly after applying your resin to the wall, inspect the surface for trapped air. Using a heat source, such as a torch or gentle warm air from a hair dryer, lightly pass over the resin to encourage bubbles to rise and pop. Take care to avoid overheating the surface, and keep moving the heat source to protect both the resin and underlying material.

If you spot bubbles after the initial setting, minor flaws can usually be corrected by allowing the resin to cure fully, then gently sanding the affected area. After sanding, wipe the surface clean before applying another thin layer of resin for a consistent finish.

Keeping Dust Away from Resin Surfaces

Dust can settle onto the resin while it’s still tacky, leading to unwanted marks or texture. To minimise this, thoroughly clean your workspace ahead of time and avoid movement or other projects nearby while the resin cures. Cover freshly applied resin with a makeshift dust cover, such as a clean box or sheet held above the surface, ensuring it doesn’t actually touch the resin.

If some dust does get caught in the finish, allow the resin to harden fully before gently sanding the surface smooth. Remove all residue, then reapply a thin coat of resin for a flawless appearance. The right application tools, such as short-pile rollers, can help achieve a smooth coat and reduce disturbances—browse our resin application rollers for suitable options.
