Polax polyurethane sanding block 220x420 mm model 200-005

Polax polyurethane sanding block 220x420 mm model 200-005 is a hand-held backing block designed to support abrasive sheets for manual sanding of large surfaces. The block measures 220 x 420 mm and combines a firm core with slight flexibility to maintain even contact with wood, plaster, paint and composite panels. It is intended to help achieve uniform material removal, consistent surface preparation and reduced hand fatigue during extended sanding sessions.

Advantages

The polyurethane construction offers a balance of stiffness and resilience, enabling the block to conform slightly to surface contours while providing stable pressure for an even sanding result. Its large working area reduces the number of passes required on broad surfaces and supports full-size abrasive sheets. The material resists abrasion and moisture, extending useful life under normal workshop conditions. The block’s dimensions make it suitable for covering wide swathes quickly and for maintaining a consistent sanding pattern across panels and boards.

Suitable for

• Sanding large wooden panels and furniture components
• Smoothing plaster, drywall and skim coats before finishing
• Preparing painted surfaces for repainting or refinishing
• Levelling composite panels and fiberglass surfaces

Key specifications

• Material: polyurethane backing
• Nominal size: 220 x 420 mm working surface
• Flexibility: firm with slight conformability for even contact
• Intended use: manual hand sanding with adhesive or clamped abrasive sheets
• Applicable materials: wood, plaster, paint coatings, composites
• Durability: abrasion- and moisture-resistant under normal use

How to use

Attach a compatible abrasive sheet to the sanding block according to the abrasive manufacturer’s instructions; ensure the sheet is secured flat across the full working surface. Hold the block with both hands and apply even pressure while moving it across the workpiece in overlapping, consistent strokes. Use long, controlled passes along the grain on wood, and employ light, circular or cross-hatching motions where needed on plaster or paint to achieve uniform abrasion. Inspect the abrasive periodically and replace it when worn to maintain effective material removal and avoid surface irregularities.

Usage recommendations

For best results, match abrasive grit to the task: coarser grits for rapid stock removal and finer grits for final smoothing. Keep movements steady and avoid excessive localized pressure to prevent grooves or unevenness. Store the block in a dry place away from direct sunlight and solvents to maintain material properties, and clean off dust build-up on the block and abrasive between uses.
