Sanding: the indispensable basis for quality and durability

How high-quality sanding materials and techniques contribute to the end result

Sanding is an indispensable technique in various industries, but does not always get the attention it deserves, Maiburg says. In woodworking, sanding not only provides a smoother finish, but also improves the adhesion of coatings, enhancing the life and appearance of the product. In addition, sanding can create decorative effects. Product manager Marvin Dutour-Geerling of Maiburg clarifies, "With the right sanding techniques, each surface comes out at its best and creates a durable end result."

Maiburg has been supplying abrasives from Swiss manufacturer sia Abrasives to the Dutch market for almost a century. In addition to a wide range of products, the company offers training and demonstrations for professionals. Dutour-Geerling: "We show how professionals can work more efficiently and effectively with the right sanding materials."

The building blocks of high-quality abrasives

High-quality abrasives consist of multiple layers, each with a specific function. Dutour-Geerling explains which components contribute to the durability and effectiveness of abrasive materials:

- Backing: "The backing determines the stability and flexibility of the material. Backing materials can range from paper and plastic to linen, depending on the application."

- Base coating: this initial bonding layer fixes the abrasive grains and contributes to long life and even wear. "A good base coating ensures that the material performs consistently," says Dutour-Geerling.

- Abrasive grains: the choice of abrasive grain determines the final result and ranges from fine grains for wood to diamond for hard materials such as glass and stone. For an even finish, the grains are distributed evenly via electrostatic or mechanical techniques.

- Additional coating: the second layer of binder strengthens grain adhesion and increases durability. "This makes it possible to work more efficiently and with fewer replacements," said Dutour-Geerling.

Nonwoven abrasives, also known as non-woven abrasives, are becoming increasingly common. These are versatile abrasive products used for machining surfaces. They consist of a fiber structure impregnated with abrasive grains and resin, which provides a flexible, open and durable abrasive material. With nonwoven abrasives we mattify and create adhesion. It does not remove unevenness or damage. But by using it dry or wet between sanding steps and after the final sanding step, you get the best results.

Innovation in abrasive technology

The sanding industry is constantly evolving, benefiting from technological innovations that allow for more efficient, cleaner and sustainable operations. "For example, laser-perforated multi-hole discs promote optimal dust removal, which not only speeds up the sanding process, but also significantly extends the life of the sanding material. These discs are also easier to use on any machine," explains Dutour-Geerling. 

"In addition, integrated dust extraction systems help prevent clogging, ensuring a cleaner working environment and an even finish. Modern sanders with sensor technology automatically adjust pressure and speed for consistent results." Maiburg also signals that professionals are increasingly opting for sustainable binders and natural fibers. This is in line with the growing demand for environmentally friendly production methods. 

Practical sanding tips for professionals

Finally, Dutour-Geerling shares some practical tips for achieving optimal sanding results: "Start with the right grit size: start as coarse as necessary, but as fine as possible. In fact, sanding too coarse can cause deep scratches that are more difficult to remove later. Keep a logical build-up in grit size: skipping a maximum of one grit at each step allows for smoother and faster removal of sanding scratches."

This method is suitable for both machine and manual sanding. Each with its own advantages. Machine sanding often offers more even results, while manual sanding is useful in tight spaces and corners. For questions and personal advice, professionals can contact Maiburg's sanding specialists, who share their knowledge through training sessions in demo rooms or on site, focused on the customer's specific work processes.
