Abrasive pastes

Sanding pastes for dust-free sanding in woodworking

Craftsmen who work with wood, resin and other materials are aware of the health risk posed by sanding dust. The finer the dust, the deeper it penetrates into the respiratory tract and can seriously affect health. But as we know, to achieve a perfect finish, we have no choice but to work in an environment where these ultra-fine dust particles are generated. It is these ultra-fine dust particles that pose a high risk from a health perspective.

Reduce the formation of sanding dust

There are numerous methods to counteract the formation of dust. One of the most common is probably the use of an extraction system. Wet sanding is also extremely effective at reducing sanding dust. With wet sanding, it may be sufficient to saturate the abrasive with oil or water. Although an excellent finish can be achieved in this way, it is still necessary to protect the surface with oils or waxes after wet sanding.

Sanding and priming in one step

This is where sanding pastes come into play. These ingenious sanding products not only allow you to sand as dust-free as possible. They also build up a surface finish at the same time. The result is a finish that is flawless in terms of sanding quality and priming. Thanks to their priming properties, some sanding pastes ensure that no additional coating is required.  In addition, abrasive pastes create the perfect basis for polishing the surface of your workpieces to a high gloss.

The range of AbraZive sanding products

AbraZive sanding compounds are the result of collaboration with experienced craftsmen from the epoxy resin and woodworking industries. The sanding pastes make fine sanding and polishing of wood, epoxy resin and the combination of both materials surprisingly easy. The range includes polishing and sanding pastes in grit sizes from 1200 to 200,000. All products consist of specially selected abrasives that are processed into pastes using environmentally friendly raw materials. They contain soya wax, olive oil, eucalyptus oil and a natural oxidising agent.

Some tips for the perfect finish on wood

The sanding pastes have been developed to achieve a surface finish that goes beyond the typical fine sanding with sandpaper. In other words, the usual grit of 320 to 400.

These grits provide a good basis and are at least the prerequisite for further processing. By applying a sanding paste, however, you can achieve a high-end finish comparable to 1200 grit sandpaper in a very short time, starting from 400 grit.

You also have the advantage of a dust-free sanding process, as the paste binds the sanding dust.

Epoxy resin and wood-epoxy resin joints

For epoxy resin and wood-epoxy resin bonded workpieces, we recommend using fine steel wool after you have finished with 320/400 grit to remove any major imperfections in your workpiece. We have found that for both resin and resin and wood applications, the best results are achieved if you focus the movement of the steel wool so that it cuts across the marks of the sanding application. The reconditioning process is started by applying the Abrasive Polishing Paste followed by the 5K Abrasive Diamond Paste and, if necessary, processed through the grit to the Abrasive 200K Diamond Paste.

Get the ultimate finish on turned wooden workpieces

When turning, the abrasive paste is applied to the workpiece while it is still mounted on the lathe. The surface should be cleanly turned, sanded to 320/400 grit and free of dust and grease.
The best results are achieved with a lint-free cloth. We recommend that you use one cloth for the first application and a second cloth for the final finish.

Step 1:

Apply a thin layer of abrasive polishing compound to the workpiece surface. As soon as it is completely wet, polish the surface with the lathe switched on at a speed of approx. 350 rpm. Apply firm pressure and make sure that you keep the cloth in constant motion.

Step 2:

Apply the second thin layer of paste with the machine running slowly. The final finish is achieved by increasing the speed of the lathe to the safe maximum speed. Use a clean, lint-free cloth and apply firm pressure to achieve an excellent finish.

Remove all residue from the surface with a clean cloth. Then move on to the next finer grit and repeat the above steps.

How to achieve the perfect finish on flat surfaces

If you want to polish worktops, chopping boards or rivertables made of wood and/or epoxy resin, the surface should be cleaned and sanded to at least 320 or 400 grit. For epoxy resin grouting, it is recommended to use fine to very fine steel wool to remove any imperfections from the sanding process.

Once the surface is ready, use a lint-free cloth to apply a thin layer of abrasive paste to the entire surface.

Then use a rotating polishing disc to achieve the desired finish.

For even better results, use a separate polishing disc for each grit size. Work through the grits from coarse to fine. Clean the surface with a clean cloth to remove any paste residue before moving on to the next finer grit.
