Sandpaper, Sanding Blocks & Pads

When it comes to smoothing surfaces, explore RS Australia's selection of sandpapers, sanding blocks, and sanding pads. Our variety of grades, grain materials, and sheet sizes enables you to prepare any surface, from general sanding to achieving an ultra-smooth finish.

Choose from three primary abrasive materials: aluminium oxide, silicon carbide, and synthetic fibres, offered by top brands like 3M, Flexovit, RS PRO, and Norton.

How Do Sandpaper, Sanding Blocks & Pads Work?

Sandpapers or sanding pads function by using abrasive grains, like aluminium oxide or silicon carbide, to frictionally wear down surfaces. Whether you’re using sheets or rolls of sandpaper, these tools effectively level imperfections, transitioning from coarse grit to a fine surface for a professional finish.

The core mechanical principle of an abrasive paper sheet relies on grain distribution:

• Closed Coat: This design covers the entire sanding paper surface for aggressive stock removal.
• Open Coat: This design leaves gaps between grains. This open spacing is crucial for softer materials, as it prevents "loading" or clogging.

Types of Sandpaper, Sanding Blocks & Pads

RS Australia stocks a range of sanding paper options tailored to specific surface preparation tasks and material densities:

• Sheets and Rolls: Standard sandpaper sheets are the go-to choice for manual finishing and can be cut to size for various applications. For high-volume projects or woodturning, a sandpaper roll provides bulk stock that offers excellent flexibility when wrapping around curved workpieces or long timber sections.
• Hand Abrasives: Ergonomic sanding blocks and sponges are designed to hold a sanding sheet securely, providing even pressure across flat surfaces. These are ideal for manual cleaning or polishing where precision control is required to prevent over-sanding.
• Machine Abrasives: Circular or delta-shaped sanding pads are engineered for use with power tools. These sanding pads are also appropriate for rapid material removal on large areas or reaching into tight corners with detail sanders.

How to Install Sandpaper, Sanding Blocks & Pads

Properly securing your abrasives ensures safety and a consistent finish. Whether you are using a manual tool or a power sander, follow these general installation steps:

• Measure and Cut: If using a sandpaper roll, measure the required length against your tool. Cut the sanding paper cleanly to avoid overhanging edges that could tear during use.
• Align the Abrasive: For manual sanding blocks, centre the sandpaper sheets over the base. Ensure the grit face is pointing outward and the backing is flush against the block to prevent slipping.
• Secure the Fasteners: Most modern blocks use clamps or internal pins to hold the sanding sheet in place. Ensure these are tight to maintain tension across the abrasive surface.
• Machine Attachment: When fitting sanding pads to orbital sanders, align the dust extraction holes perfectly with the base plate to ensure efficient debris removal and prevent clogging.

Essential Sanding Tips for Professional Results

To achieve the best results for specific surfaces, consider these techniques:

• Sand with the Grain: When working with timber, always move your sanding paper in the direction of the wood fibres. This prevents cross-grain scratches that can become highly visible once a stain or varnish is applied.
• Utilise Wet-Sanding: For metal or automotive paint, using a waterproof abrasive paper sheet with water acts as a lubricant. This "wet-sanding" technique carries away dust particles, prevents heat build-up, and results in an ultra-smooth, mirror-like finish.

How to Choose the Right Sandpaper, Sanding Blocks & Pads

Selecting the correct abrasive ensures efficiency and prevents surface damage. Here’s a simple step-by-step guide to find the perfect sanding paper for your project:

• Step 1: Identify Your Material: For hardwoods or metal, choose a durable sandpaper roll with aluminium oxide. If you are working on plastics or finishing paint, a silicon carbide abrasive paper sheet provides the necessary precision and flexibility.
• Step 2: Determine the Stage: Use a heavy-duty sanding sheet for stripping old varnish or levelling rough timber. For final surface preparation, lightweight sandpapers are better suited for light scuffing between coats.
• Step 3: Select the Grit Grade: Start with a coarse grit (40–60) for rapid removal. Progress to a medium grit (80–120) with manual sanding blocks to smooth out scratches, and finish with a fine grit (150–220+) sanding pads for a professional, touch-dry surface.
