    SIA 7983 siasponge flex is a double-sided flexible sanding sponge designed for manual surface preparation, matting and intermediate sanding. Thanks to the soft PU foam backing, the sponge adapts well to curved, profiled and hard-to-reach areas and can be used for dry and wet sanding.

  • SIA 7983 siasponge flex double-sided sanding sponge 98 x 120 x 13 mm is a professional flexible abrasive sponge designed for manual surface preparation, matting, intermediate sanding and processing of hard-to-reach areas.

    This product card is prepared without specifying the grit, because the grit will be selected as a product variant. The SIA 7983 siasponge flex range includes different grit options, so one product can conveniently be offered with selectable variants depending on the required sanding stage.

    7983 siasponge flex is a double-sided sanding sponge with aluminium oxide abrasive, soft PU foam backing, elastic bonding agent and mechanical coating. The Flex Pads version measures 98 x 120 mm, has a thickness of 13 mm and is suitable for dry and wet sanding.

    SIA 7983 siasponge flex is especially suitable for curved, profiled, round and complex-shaped areas. Thanks to the very soft foam backing, the sponge adapts to the surface shape and helps achieve an even sanding result even on more difficult surfaces.

    The sponge can be used dry or wet. This provides more flexibility when working with different coatings, preparation stages and surfaces. Wet sanding can be useful when cleaner, gentler processing and less dust are required, while dry sanding is convenient for fast preparation work.

    7983 siasponge flex is used for roughening surfaces before painting or clear coating, as well as for intermediate sanding of old and new clear coats, primers, filler primers and paints. It is suitable for roughening wood and plastics, roughening old and new clear coats, filler primers and paints, fine sanding of filler primer in hard-to-reach areas, matting clear coats and intermediate clear coat sanding.

    The double-sided abrasive coating allows both sides of the sponge to be used conveniently, making it suitable for manual work where pressure must be controlled and the tool must adapt to the surface shape. This is especially important in automotive body preparation when working around edges, corners, profiles, curves, bumpers, plastic parts and other more complex areas.

    Thanks to the 3D properties created by the foam backing, bonding system and abrasive, the sponge has reduced clogging. This helps maintain more even processing and a stable sanding result when working with paint, primer, filler primer, plastic, old clear coat layers and composite materials.

    The sponge structure helps reduce the risk of sanding through when working with higher contact pressure. This is important when sanding edges, curved areas and surfaces where overly aggressive sanding could damage the coating or remove too much material.

    SIA 7983 siasponge flex is suitable for automotive body preparation, paint preparation work, primer processing, clear coat matting, intermediate sanding and surface roughening before further coating. It can also be used with wood, plastic, paint, primers, clear coats, composite materials and polyester fillers.

    SIA 7983 siasponge flex double-sided sanding sponge is a practical choice for professional and precise manual sanding when flexibility, good shape adaptation, an even sanding pattern and comfortable work in hard-to-reach areas are required.

    Use recommendations:

    Select the correct grit according to the task and surface preparation stage.
    Use for manual dry or wet sanding.
    Before work, make sure the surface is clean and properly prepared.
    When working with paints, primers or clear coats, follow the recommendations of the selected paint system.
    On curved areas, allow the sponge to adapt to the surface shape and avoid excessive pressure.
    Work carefully on edges and corners to avoid sanding through the layer.
    Sand with even movements while controlling pressure.
    For wet sanding, use clean water or a suitable sanding liquid according to process requirements.
    During work, periodically remove sanding residue from the surface and sponge.
    Do not use an excessively worn or contaminated sponge on sensitive surfaces.
    After sanding, remove dust or sanding residue and prepare the surface for the next coating stage.
    Store dry, clean and protected from contamination.
