Sandpaper & Sanding Blocks

Effective sanding - the surface preparation step that determines the quality of every painted, stained, or varnished finish - depends on having the right abrasive grade and the right backing for the material and the task. At the DIY Hardware Store, our sandpaper and sanding blocks range covers the sheet abrasives, sanding sponges, and cork and rubber sanding blocks used across woodworking, decorating, metalwork, and automotive finishing projects.

Sandpaper grit selection follows a consistent numbering system: lower numbers (40-80 grit) are coarse, for initial material removal and shaping; medium grades (100-180) suit general sanding and scratch removal; fine grades (220-400) prepare surfaces for the final coat; very fine (600+) is used for between-coat flatting and finishing on lacquer and varnish systems. Starting too fine wastes time; starting too coarse risks leaving scratches that show through the finished coat.

Sanding blocks provide a flat, rigid backing that ensures the abrasive cuts evenly across a surface rather than following the contours of the fingers - essential for achieving a flat, even result on joinery and furniture. Available at the DIY Hardware Store in individual sheets, assorted packs, and cork and rubber block sets.
