Sanding Sponges

Flexible Support for Curved Surfaces

The cushioned backing helps the abrasive follow curves and contours, making sanding sponges useful on rings, bangles and shaped metalwork. They provide a comfortable hand-held abrasive for blending surface marks and refining areas that are awkward to sand with a rigid support.

Use light, even pressure and take care around crisp edges and raised detail: a flexible sponge can round these features if worked too heavily. For maintaining flat surfaces, consider abrasive paper on a firm backing or a suitable sanding stick.

Choosing Your Grade

The range includes medium through micro fine grades, along with numbered grits from 100 to 400 and a five-piece assortment. Start with the least coarse grade that will remove the marks present, then progress to finer abrasives as required. Higher grit numbers indicate a finer abrasive within the same grading system; named grades should be compared using the individual product details.

Remove the scratches from each stage before moving on. Changing the direction of sanding can help you see remaining marks, and checking under good lighting helps avoid carrying deeper scratches into polishing.

Jewellery and Workshop Uses

Suitable grades can be used for sanding and pre-polishing gold, silver, platinum, brass and copper. Choose the grade for your material and starting surface, and test first when working on unfamiliar finishes. Avoid sanding plated or coated surfaces unless removing or altering that finish is intended.

Keeping Your Abrasives Clean

Keep grades separate and clear loose abrasive debris from the work between stages. The washable sponges identified in the product descriptions can be cleaned and reused; follow the guidance for the particular product. Replace worn or damaged sponges when they no longer cut evenly.
