Product Overview<\/h2>\n

GUSHI Diamond Sanding Sheets are flexible diamond abrasives for hand finishing materials that defeat conventional paper. Electroplated nickel-bond sheets in 60# to 400# grit handle aggressive shaping, chip repair and edge smoothing; resin-bond sheets in 800#, 1500# and 3000# grit hone and polish afterwards. An open dot pattern keeps the sheet flexible and clears swarf, and because the abrasive is diamond there is no pigment to bleed into light stone. Sizes are 55 \u00d7 90 mm, 100 \u00d7 100 mm and 120 \u00d7 180 mm, the sheets work wet or dry, and they typically last 10 to 30 times longer than silicon carbide paper. They are made by Huzhou Gu’s Imp. & Exp. Co., Ltd., a Zhejiang diamond tool and abrasives manufacturer founded in 2004 that is ISO 9001:2015 certified and exports to more than 20 countries.<\/p>\n

Diamond is not simply a finer abrasive, it is a different class of one. At Mohs 10 it cuts granite, engineered stone, porcelain and glass rather than wearing against them, so the sheet removes material steadily instead of glazing over. That is why a single diamond sheet can finish an edge that would consume a stack of conventional paper.<\/p>\n

The two bond types exist because coarse and fine work need opposite behaviour. Electroplating anchors a single layer of diamond in nickel, leaving maximum grain exposure for fast, aggressive cutting. Resin embeds finer diamond in a softer matrix that yields slightly, which is what produces a polished rather than a scratched surface. Used in sequence, they cover the whole job from a chipped edge to a final gloss.<\/p>\n<\/div>\n

How Diamond Sheets Cut Hard Material<\/h2>\n

Cutting rather than rubbing<\/h3>\n

Conventional abrasives such as silicon carbide work by scratching, and on materials harder than the grain they stop scratching and start rubbing. Diamond is harder than granite, quartz and glass, so it keeps cutting. The practical difference is that the sheet removes material at a steady rate from first contact to the end of its life, instead of the rapid decline seen with ordinary paper on dense stone.<\/p>\n

Why the dot pattern matters<\/h3>\n

A continuous diamond coating would be stiff and would clog within seconds. The open dot pattern leaves gaps between the diamond islands: the sheet stays flexible enough to follow a curve or a bullnose edge, and swarf and water escape through the gaps instead of packing the surface. Flexibility and clogging resistance come from the same design feature.<\/p>\n

Exposure and why the bond changes with grit<\/h3>\n

Electroplating holds each diamond particle in nickel with most of the grain exposed, which is what makes coarse sheets so aggressive \u2014 but that same exposure leaves a scratch pattern too coarse to polish with. Resin holds finer diamond in a matrix that wears back slightly during use, keeping grit exposure low and controlled, which is exactly what produces a honed and then polished surface.<\/p>\n

Heat is still the enemy<\/h3>\n

Diamond conducts heat well, but the bond does not. Overheating a resin sheet softens the matrix and sheds diamond prematurely; overheating glass or engineered stone can crack or discolour it. Water is not optional on fine work \u2014 it carries heat and swarf away and is the single biggest factor in both sheet life and finish quality.<\/p>\n<\/div>\n

\n

Key Features Explained<\/h2>\n

High grinding efficiency<\/h3>\n

Because the exposed diamond cuts continuously, these sheets remove stock faster than any conventional abrasive at the same grit. On a chipped countertop edge or a badly scratched glass panel, that translates directly into less time per repair and fewer sheets consumed per job.<\/p>\n

No dye left on the surface<\/h3>\n

Some abrasive papers and pads use coloured pigments or minerals that can bleed into pale stone, leaving a stain that has to be ground out \u2014 a costly problem on white marble, onyx and light engineered stone. Diamond carries no pigment, so there is nothing to transfer. This is one of the most valued properties of diamond sheets on light-coloured material.<\/p>\n

Flexibility for real geometry<\/h3>\n

The sheet folds around a bullnose, follows an internal radius and reaches into corners that a rigid pad cannot. Cut with scissors to a smaller shape when needed, it handles the awkward geometry that makes up most on-site repair work rather than only flat panels.<\/p>\n

Long service life<\/h3>\n

Anchored in metal or resin rather than glued to paper, diamond grains stay in place. Sheets typically last 10 to 30 times longer than silicon carbide paper on hard material, which more than offsets the higher unit price and reduces the number of consumables a crew has to carry.<\/p>\n

Wet or dry flexibility<\/h3>\n

Wet is recommended for dust control, cooling and finish quality, but dry use is entirely practical for quick touch-ups and small repairs where water is inconvenient. The same sheet does both, so a single stock covers workshop and site work.<\/p>\n<\/div>\n

Pro Tip:<\/strong>\u00a0Rinse or wipe the surface between grit stages. A single coarse grain carried over to the next stage will leave a scratch that runs the full length of the edge, and it will only become visible after polishing \u2014 which means starting the sequence again.<\/div>\n<\/div>\n

Bottom line:<\/strong>\u00a0Use electroplated sheets to remove material, resin sheets to refine it, and keep silicon carbide paper for softer materials where diamond is unnecessary. Buying the seven-piece sequence means every stage is matched to the one before it, which is what produces a consistent finish rather than a hopeful one.<\/p>\n<\/div>\n

How to Use: Step-by-Step Guide<\/h2>\n
    \n
  1. Assess the damage and choose the coarsest grit needed \u2014 60# for chips, 200# or 400# for light scratches.<\/li>\n
  2. Clean and dry the surface so grit cannot be carried into the next stage.<\/li>\n
  3. Cut the sheet with scissors if the area is small, tight or profiled.<\/li>\n
  4. Wrap it around a sanding block or hold it flat; keep the whole surface in contact.<\/li>\n
  5. Wet the area, or plan dry work with dust control and respiratory protection.<\/li>\n
  6. Work the electroplated grits first, 60 \u2192 120 \u2192 200 \u2192 400, with light, even pressure.<\/li>\n
  7. Rinse the surface between every grit stage and check the scratch pattern under good light.<\/li>\n
  8. Move to the resin grits, 800 \u2192 1500 \u2192 3000, for honing and polish.<\/li>\n
  9. Keep the sheet and the material wet during fine stages to control heat.<\/li>\n
  10. Use the dot side down; a sheet that loads should be rinsed rather than pressed harder.<\/li>\n
  11. On glass and gemstones, use light pressure throughout and never let the surface heat up.<\/li>\n
  12. Inspect the finished area at an angle to the light, then dry and protect the surface.<\/li>\n<\/ol>\n
    Important:<\/strong>\u00a0Wet sanding is strongly recommended \u2014 silica dust from stone, engineered stone and concrete is hazardous to breathe, and dry sanding without extraction and respiratory protection is not safe. Never skip more than one grit step, never let the sheet or workpiece overheat, and always test the sequence on an offcut or an inconspicuous area before working on a visible surface.<\/div>\n

    Preguntas frecuentes<\/h2>\n
    \n

    What is the difference between the electroplated and resin diamond sheets?<\/h3>\n

    Electroplated sheets hold a single layer of diamond in a nickel bond and come in 60, 100, 120, 200 and 400 grit. They are aggressive, remove material fast and are used for shaping, chip repair and edge smoothing. Resin sheets embed finer diamond in a resin layer at 800, 1500 and 3000 grit and are used after the electroplated stages to hone and polish. Use electroplated first, then resin.<\/p>\n<\/div>\n

    \n

    What grit sequence do I need, and what do the colours mean?<\/h3>\n

    A standard seven piece set runs 60, 100, 200 and 400 in electroplated bond, then 800, 1500 and 3000 in resin bond. The conventional colour coding is green for 60, black for 100 or 120, red for 200, yellow for 400, white for 800, blue for 1500 and orange for 3000. Work through every stage in order and never skip more than one grit.<\/p>\n<\/div>\n

    \n

    Do diamond sheets leave colour or dye on light coloured stone?<\/h3>\n

    No. Diamond is the abrasive, so there is no coloured pigment or mineral to transfer. That is a real advantage over some conventional abrasive papers and pads, whose pigments can bleed into light marble, onyx and engineered stone and leave a stain that has to be ground out. Diamond sheets are the safe choice on pale material.<\/p>\n<\/div>\n

    \n

    Should they be used wet or dry?<\/h3>\n

    Both work. Wet use is recommended because water keeps the sheet and the stone cool, carries away swarf, suppresses silica dust and extends sheet life considerably. Dry use is convenient for small on-site repairs and touch-ups, provided dust is controlled and respiratory protection is worn.<\/p>\n<\/div>\n

    \n

    How long do they last compared with silicon carbide paper?<\/h3>\n

    Because diamond is the hardest known abrasive and the grains are anchored in metal or resin rather than glued to paper, these sheets typically last 10 to 30 times longer than silicon carbide paper on granite, engineered stone and porcelain. The gap is widest on hard, dense material, where conventional paper glazes quickly.<\/p>\n<\/div>\n

    \n

    What sizes are available and can they be cut?<\/h3>\n

    Standard sizes are 55 x 90 mm, 100 x 100 mm and 120 x 180 mm, with other dimensions made to order. The flexible backing can be cut with scissors or shears to a smaller shape for tight corners, internal radii and detailed work, so one sheet can be divided to suit several awkward areas.<\/p>\n<\/div>\n

    \n

    Can they be used on glass and gemstones?<\/h3>\n

    Yes. The fine resin grits smooth ground glass edges and remove scratches from glass panels, and the sheets are widely used in lapidary work for shaping and pre-polishing gemstones and soft stone. Use light pressure and keep the surface wet, because glass and many gemstones are sensitive to heat.<\/p>\n<\/div>\n

    \n

    What is the MOQ and what can be customised?<\/h3>\n

    The OEM MOQ is 500 pieces, and sizes, grits and bond types can be mixed in one order. Customisation covers sheet size and shape, grit range, bond type, backing material, velcro or plain back, colour coding, set composition and private-label packaging. Production runs under ISO 9001:2015; lead time is 5 to 10 days for standard items and 15 to 30 days for custom.<\/p>\n<\/div>\n<\/div>\n
