Uneeda says its new Ekadiamond sponges have a flexible foam backing designed specifically to reduce loading, when hand sanding curves, contours, mouldings and complex profiles. Unlike conventional abrasive sponges, the company adds, Ekadiamond sponges give out almost no grain shedding, offering a cleaner and smoother sanded surface for all applications. The unique diamond shape pattern also allows for faster heat dispersion for a longer lifespan.
