Best for: contractors and serious DIYers who need reliable, long-lasting sheets for aggressive material removal. Caution: may appear stiff in very dense abrasives, requiring careful handling on delicate surfaces.
Mercer Industries 60 Grit 12″ x 18″ Sheets
Product features: 20 pre-cut sheets for standard 12″ x 18″ buffers. Silicon Carbide grain supports consistent performance for hardwood or concrete. Extra heavy backing provides tear resistance and durability. Best for: users who need faster material removal than finer grits or when addressing old finishes. Caution: coarser grits may leave visible scratches if not followed by finer grits.
HUAALIUCHE 220 Grit Sanding Screen Sheets (10-Pack)
Product features: 12″x18″ screen discs, 220 grit, designed for floor buffers or rotary machines. Use to remove old finishes and wax, between coats, and to restore worn wood floors.

Buying Guide: Key Considerations For 12″ X 18″ Sanding Sheets
- Material and grit range: Silicon Carbide offers clean cuts and good dust control. A mix of coarse (60-80) and finer (120-220) grits covers initial stock removal through final smoothing.
- Backing durability: Extra-heavy or heavy-weight backings increase tear resistance, ideal for repeated use on tougher surfaces. If you’re a weekend DIYer, look for sheets that balance durability with cost.
- Compatibility: Ensure sheets fit your buffer or rotary machine (12″ x 18″ standard). Check for square buff compatibility and whether the sheets are pre-cut for your specific machine model.
- Clog-resistance and reusability: Mesh or screen sheets (like 60–220 grit options) tend to clog less, especially on finishes and wax. Consider reusable designs if you have frequent refinishing projects.
- Project type: For hardwood floors, start with 60–80 grit for heavy finish removal, then progress to 120–180 grit for smoothing, and finish with 220 grit for a fine surface. For concrete, follow similar grit progression based on the finish you want.
- Wet vs. dry use: Some sheets are suitable for wet sanding to reduce dust and heat. Verify use cases if your project requires wet or dry sanding.
FAQ
- What grit should I start with for refinishing hardwood floors?
Begin with 60–80 grit for heavy stock removal, then move to 120–180 grit for smoothing, and finish with 220 grit for a fine surface. - Are 12″ x 18″ sheets compatible with most floor buffers?
Yes, most 12″ x 18″ sheets are designed to fit standard square buffers and many rotary floor machines. - What is the benefit of silicon carbide backing?
Silicon carbide offers durable cutting and good tear resistance, helping sheets last longer under heavy use. - When should I use screen sheets versus solid sheets?
Screen sheets (mesh) are best for clog-prone finishes and finish removal; solid paper sheets are sturdy for heavy stock removal. - Is it better to use multiple grits in sequence or stick to one grit?
A sequence improves finish quality and reduces noticeable scratches; start coarse for stock removal, then progressively finer grits. - Can I use these sheets for both wood and concrete?
Yes, many of the listed sheets are suitable for hardwood and concrete, but follow the manufacturer’s recommendations for each surface type.
