Sandpaper 400,500,600

Wamod Abrasive Papers, 400, 500 and 600 Grit

A set of abrasive papers in three consecutive grits covers the part of sanding where the marks left by the mold parting line, the remains of sprue gates and sanded-back filler are taken off a model. The numbers 400, 500 and 600 in the name are the designation of the coarseness of the grit: the higher the number, the finer the paper and the smoother the surface after sanding. Three grits make it possible to work in steps, which is the only way to reach a smooth surface with no scratches.

Use

• Sanding down parting lines, sprue nubs and mold seams on plastic parts.
• Sanding filler level with the surface around it before spraying.
• Knocking back glossy plastic so that it holds primer and paint better.
• Fine leveling of a surface between coats of varnish.

How to sand

Always work from coarser to finer, that is 400, then 500 and finally 600; a skipped step gives itself away only under the paint, when the scratches from the coarser paper come out. It pays to back the paper with a block or a strip, so that the area being sanded stays flat and no hollows appear. On plastic, wet sanding works well: the paper is dipped in water with a drop of detergent, the sanding dust does not stick and the surface is cleaner. Degrease the model and clear the sanding dust off it before spraying. Sanding plastic and filler dry over a larger area without respiratory protection is not advisable.

Who the set is for

• Builders of plastic models who want a surface ready for paint.
• Modelers working with filler, where sanding in steps is a necessity.
• Beginners, who will appreciate a ready-made trio of consecutive grits.
