The 9" Spike Roller No Frame is engineered to remove air bubbles and break surface tension in epoxy coatings, self-leveling underlayments, and decorative overlays. With 1-¼” nylon spikes, it ensures smoother, more uniform surfaces by releasing trapped air and preventing imperfections. Ideal for medium-sized projects, the 9” width offers great control without sacrificing coverage. This roller pairs best with a wide-frame handle (sold separately) to prevent contact with spikes during application.
