Manual sanding supply Proline 49020 — abrasive sheet 75 mm × 457 mm, 1 pc

Proline 49020 is a manual sanding supply consisting of a single abrasive sheet sized 75 mm × 457 mm. The sheet is manufactured on a flexible heavy cloth backing (Type X) with a normal full alumina abrasive coating and a synthetic resin binder. It is designed for hand sanding of wood, paint, varnish, light metal and plastic surfaces, providing a replaceable sanding surface compatible with manual sanding blocks or templates for detail work, leveling and surface preparation.

Advantages

The flexible heavy cloth backing ensures durability and conformability to curved or irregular surfaces while resisting tearing during intensive manual use. Full alumina abrasive offers consistent cut rate and long life on a range of materials, and the synthetic resin binder provides stable adhesion of abrasive grains and moderate resistance to clogging. Supplied as a single sheet, it is easy to cut to custom sizes and fit into hand sanding blocks or jigs.

Suitable for

• Hand sanding and finishing of wood surfaces
• Paint and varnish surface preparation and removal
• Light metal deburring and finishing on steel, cast iron and non‑ferrous metals
• Sanding plastics and composite materials
• Detail work, contours and small-area leveling

How to use

Measure and cut the abrasive sheet to fit your manual sanding block or template if required. Use the sheet by wrapping it around a block or holding it by hand for detail sanding. Apply even pressure and move with the grain on wood or follow the surface contour on metals and plastics. Replace the sheet when abrasive performance decreases or when clogging prevents effective sanding.

Usage recommendations

For best results, start with a coarser grit for material removal and progress to finer grits for finishing. Use light to moderate pressure to avoid premature wear of the abrasive and to maintain surface control. When sanding painted or varnished surfaces, periodically inspect and replace the sheet to prevent glazing; when working on metals, clean swarf from the surface to reduce clogging.
