Frequently asked questions
What is this set consisting of backing pad and accessories for?
It is used with wood and metal sanders for sanding, polishing, or finishing operations on the specific material indicated in the model.
The choice of model depends on the backing pad diameter and type of fastening (self-adhesive or velcro) and the type of application. Compatible with sanders of the corresponding diameter.
Which grit to choose?
K36-K60 for aggressive roughing, K80-K120 for intermediate sanding, K150-K240 for pre-painting finishing, K320+ for mirror surfaces.
The most common mistake is skipping intermediate grits: going from K60 to K240 leaves deep marks that cannot be removed. Always proceed in consecutive steps (e.g., K80 → K120 → K180).
What materials is it compatible with?
The model indicates the specific material (stainless steel, aluminum, wood, plastic). Using the correct abrasive optimizes durability and processing quality.
For stainless steel, use abrasives with a suitable binder to avoid heating and deformation. For aluminum, prefer abrasives with reduced loading. For wood, normal corundum is the standard choice.
How many pieces does the package contain?
The number of pieces is indicated in the model (e.g., 4 or 5 or 6 pieces). Multiple packages allow for managing replacements without machine downtime.
For intensive use, it is advisable to keep at least 2-3 packages of the most used grits in stock, so as not to interrupt production when a belt/sleeve runs out.
How are abrasives stored?
Store in a dry place, away from humidity that can alter the binder. Keep them in their original packaging until use to preserve grit and adhesive.
Humidity particularly damages self-adhesive backing pads and paper-based abrasive belts. Ideal temperatures: 18-25 °C, relative humidity 40-60%. Closed and ventilated warehouse.
