Wet sanding of epoxy resin – Step by step guide

As a rule, wet sanding of cast resin is carried out by hand. For your own safety, do not use an electric sanding machine for this method. Since water is used, the risk of suffering an electric shock is simply too high. However, an air-powered sander is a good alternative if you want to work on a large surface.

To keep the abrasive paper smooth during wet sanding, we recommend a hard rubber sanding block. If the surface is curved, it may be necessary to use a suitable backing. As an alternative to an underlay or block, you can simply place the abrasive paper in your hand and then dip it in water. Unfortunately waterproof sandpaper is relatively rigid and inflexible. This can be a problem if you want to work on structured or very irregular surfaces such as a sculpture. Here the paper does not adapt sufficiently to the existing curves. For these cases we recommend a sanding pad, e.g. the 3M Scotch Brite. This is much more flexible than sandpaper and can also be used wet.

Material used in this process;

3M Scotch Brite Schleifpads sehr fein, 25 Stück: Hochwertige Schleifpads von Scotch Brite, 25 Stück. Sehr feine Körnung. Flexibel für bequemes Schleifen von Hand.

Prepare a slightly larger container of water near your workplace. If the surroundings are very cold, you can of course also use warm water. sand the surface evenly with circular movements and dip the sandpaper into the water again and again. At the end there should be no more sanding marks of the previous grain.

Instead of constantly wetting the sandpaper again, you can also wet the surface. Use a spray bottle filled with water and spray your work piece again and again.

During your work, remove the existing sanding residue more often with a cloth. This way you can check the progress of the sanding process from time to time. If you change to a finer grain, the surface must be cleaned beforehand to prevent the coarser grains of sand from causing new sanding marks.

“Tip: Remove the existing sanding residues on your workpiece immediately after you have finished sanding. Once they have dried, they are very difficult to get off the surface.”
