siafast Delta Sheets are designed for abrading Bonaseal sealer to eliminate grain raise. Delta Sheets are used attached to Bona Conditioning Pads. The unique delta shape and nature of the abrasive compound provide superior performance with a minimum of loading.
Note: siafast Delta Sheets are only necessary on open wood grains, such as red or white oak, that are subject to grain raise. A Conditioning Pad alone is usually sufficient for tight grain woods such as maple, birch or cherry.
