Sanding is a must-do in any paint or coating project. It is essential for giving your work an amazing smooth finish. To make sanding faster and effortless, we recommend power tools over manual sanding. Random Orbital Sanding is highly recommended for aggressive sanding due to its proclivity for removing a lot of material.

Choosing the correct abrasive for the job is also important.

S Performance: cleaner, safer and more efficient thanks to a new hole pattern. Optimised air flows guarantee maximum extraction performance of the multi-hole sanding discs in the new S Performance range from sia Abrasives. Sanding dust is extracted more efficiently and the lifetime is increased. In addition, the hole design reduces dust emissions.

1944 siaone combines the quality with aggressive cut and optimum lifetime. For price-conscious users for working with various materials, for example: bodyfiller, primer filler, varnish, paint and wood.

Ensure you have the correct PPE for sanding. We recommend disposable FFP2 Face Masks, as they provide optimum protection from airborne particles such as dust, mist and fumes. FFP2 Masks are suitable for plastering and sanding. Wear eye protections such as safety glasses and goggles to prevent flying debris from sanding. Wear Safety Gloves when using power tools such as sanders and grinders.

Ensure you have the correct backing pad and/or disc saver for the siaone sanding disc.


1944 siaone discs are hook and loop and have abrasive-material backing similar to Velcro. The backing pads have microscopic hooks on their surface, while the hook and loop discs have corresponding tiny loops on their backings.

To attach the 1944 siaone disc to your sander, face your sander upside down and place the surface of the disc on the backing pad and press both surfaces together. Ensure all holes are aligned for extraction. Peel back whenever you want to change the disc.


Please dispose of the abrasive material correctly. Please seek local advice for dealing with this material.


It is important to understand when using abrasives to check whether your full system is suitable for the task in hand. We are able to advise you on sanding equipment and materials to achieve the perfect finish. Please click the contact us button for advice.
