Mr Paper Card Sandpaper #240

Mr. Paper Card Sandpaper, 240 grit (Gunze)

Sandpaper from the Japanese manufacturer Gunze in a handy card format, in 240 grit. This is the coarser end of the range, meant for the first stage of sanding: removing the remains of sprue gates after a part has been cut from the runner, leveling parting seams and flattening uneven surfaces. The card format sits well between the fingers and does not curl the way a loose sheet does, so you can work with it precisely even on a small area. The dimensions, the number of sheets in the package and whether it suits wet sanding are stated on the box.

Use

• Use 240 grit as the first step and never as the last one, because it leaves visible scratches that have to be sanded out with a finer paper.
• Sand with short strokes in one direction and keep checking the shape of the part against the light.
• Do not press on the plastic; a coarser grit removes material fast and an over-sanded detail cannot be brought back.
• Clean the dust off the surface after sanding, otherwise it will show through the primer as a grainy texture.
• It is worth putting a filler primer on the sanded spot, which closes the remaining scratches.

Who it is for

For anyone who builds plastic models, because a coarser grit is basic equipment and without it the seams on hulls and bodies cannot be dealt with decently. For finishing the surface, add finer grits to it; the same line also comes in 400, 600, 800 and 1000 grit, so you can put together the whole sequence.

Do not inhale the sanding dust and work in a ventilated space; on larger areas a respirator is useful. Keep the sandpaper dry.
