Big epoxy spiked rollers are specialized tools used to release trapped air bubbles and flatten self-leveling epoxy coatings over large floor areas. Larger industrial widths typically span 500mm to 800mm (20 to 32 inches) to maximize efficiency and coverage. Heavy-Duty Frames: Large rollers use sturdy, double-arm steel frames to distribute pressure evenly. Spike Height Options: Typically feature 11mm to 21mm plastic or metal teeth depending on the thickness of the floor coating. Extension Pole Adapters: Outfitted with threaded handles to attach long extension poles so installers can roll the floor while standing upright.
