This is a 230mm x 280mm abrasive sandpaper sheet designed for manual sanding, hand blocks and sheet clamps. The primary use is general surface preparation—smoothing timber, removing old paint, deburring metals and preparing substrates for finishing. The sheet size is a standard half-sheet format that fits most hand sanding blocks and can be cut to suit third-sheet holders or detail work.

The sheets are available in several abrasive grains and backing constructions. Common abrasive materials offered include aluminium oxide (general-purpose, durable on hardwoods and steel), silicon carbide (sharp, used for glass, ceramics and fine finishing) and natural garnet (preferred for hand-sanding and fine woodworking). Grit grades are specified to FEPA “P” designation and ISO 6344 grain-size conventions, typically ranging from P40 coarse to P400 fine; waterproof (wet/dry) silicon carbide versions are available for wet sanding. Backing options include paper-backed (suitable for hand use) and heavier cloth-backed grades where greater tear resistance is required. Sheets may be supplied in open-coat (reduced loading on soft materials) or closed-coat formats depending on application.

The product is manufactured to recognised abrasive designations and quality systems, conforming to FEPA/ISO 6344 grit identification and produced to meet relevant British and DIN quality expectations for abrasive media. Thread, head and drive types are not applicable for sheet abrasives.

Typical applications include carpentry and joinery, cabinetmaking, painting and decorating, automotive refinishing and metal fabrication, plus marine and restoration work where controlled material removal and finish consistency are required. Key benefits include selection of abrasion type to match substrate (aluminium oxide for general use, silicon carbide for wet-sanding and fine work), consistent FEPA/ISO grit grading for predictable finish, and backing choices that balance flexibility and tear resistance for hand sanding. Waterproof variants permit wet-sanding and reduce dust, while cloth-backed options improve durability on aggressive tasks.
