Epoxy Resin Microbubbles: Small Issue, Big Impact
The Reality of Bubbles in Cured Resin
A New Surface: Achieving Clarity Again
While removing the bubbles from cured resin isn't feasible, there are ways to restore the surface's smoothness and clarity. Here's a two-step process to help:
Start with Sanding: Use coarse-grit sandpaper (200 grit) to sand the entire surface, particularly areas with bubbles. This roughens the surface, prepping it for the next layer of resin.
Clean the Surface: Clean the surface and remove any debris that is leftover from sanding. Compressed air can be very helpful in this step to remove stubborn debris.
Apply a Fresh Layer: After sanding and cleaning away the dust, mix a new batch of resin. Apply it over the sanded piece. This new resin layer will fill in any indentations from the bubbles and render a smooth, clear finish.
