Product Range
Sanding Discs
150mm and 178mm siafast hook-and-loop discs for rotary and edge sanders. Available in grits from 24 through 180 for coarse levelling, mid-cut, and fine finishing. The 1815 siatop range delivers fast, cost-effective results on hardwood and softwood species.
Sanding Belts and Rolls
Belts for drum sanders in standard Australian machine sizes. Consistent grit distribution for even scratch patterns and smooth transitions between grits.
Why sia?
Swiss precision manufacturing. Consistent grit bonding means longer belt and disc life. Designed for the demands of Australian hardwoods which dull abrasives faster than European softwoods.
Frequently Asked Questions
What grit sequence should I use for floor sanding?
A typical sequence for Australian hardwoods: start with 40 grit to level the floor, then 60, 80, 100, and finish with 120 or 150 grit depending on the finish system. Some finish manufacturers specify a maximum grit — check the finish technical data sheet before final sanding.
What is the difference between 1749 and 1815 series discs?
The 1749 series uses a heavier cloth backing suited to aggressive initial cuts and edge sanding. The 1815 siatop series is optimised for fine finishing with consistent scratch patterns. Use 1749 for coarse work and 1815 for mid-to-fine grits.
How long should a sanding belt last?
Belt life depends on timber species, grit, machine condition, and operator technique. On Australian hardwoods (which are significantly harder than European softwoods), expect shorter belt life than manufacturer ratings based on European species. Replace belts when cut rate drops noticeably — pushing a dull belt causes heat buildup and burn marks.
Do sia discs fit my sander?
sia siafast discs use the hook-and-loop (velcro) attachment system, which is compatible with all major sander brands including Bona, Lagler, Festool, and Galaxy. Check your sander's disc diameter — EcoGrit stocks 150mm and 178mm sizes.
