cheap abrasive sandpaper pads sanding pad

Sandpaper is produced in different grit sizes and is used to remove small amounts of material from surfaces,either to make them smoother (for example, in painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make the surface rougher (for example, as a preparation for gluing).

They can be punched into different shapes as triangular, circular, rectangular and other irregular shapes.

Convenient loop backing can be used with any velcro disc holder or sander.

The sandpaper is easy to replace when worn. The everlasting grains and paper backing significantly extend the already long life.

The sandpaper can be fixed on electrical or pneumatic tools to grind, polish for stainless steel, ship, automobile, furniture, aviation, machinery, building, instrument, metal and so on.

Sandpaper Buying Guide

Sandpaper is available for use with power tools and for sanding by hand:

Power-sanding products remove material quickly and efficiently. They're a good choice for getting rid of blemishes and for shaping and leveling wood. Power sanding is an effective method of preparing metal surfaces for paint. Sandpaper for power sanding comes in sheets, discs and belts designed to fit specific power tools. Some tools also accept sheets cut to size.

Hand-sanding products give you a lighter touch for woodworking and finishing. You have better control and can sand areas that a power sander can't reach. With proper technique, the scratches align with the wood grain and are less visible. Hand sand wood as final preparation for finishes and between finish coats. Sandpaper for hand sanding comes in sheets you cut to the size you need. You can use some sandpaper for both hand sanding and power sanding.

Sandpaper types

One way to determine which sandpaper will work best for a particular job is to know the abrasive materials and their properties.

Some papers use natural abrasives:

• Garnet is good for hand sanding. It works well on raw wood — removing light scratches and preparing the surface for finishing. The abrasive particles break during use, providing new edges for removing material, but garnet sandpaper wears quickly.
• Emery works for both hand sanding and power sanding metal. Use coarser grits to remove rust or paint and finer grits to polish. Emery sandpaper often has a cloth backing and is also known as emery cloth.

Other abrasives are manmade:

• Aluminum oxide is a common sandpaper type that works on wood, plastic, metal and drywall. The particles break during sanding, constantly exposing new, sharp edges. Aluminum oxide sandpaper is long-lasting, making it a popular choice for power sanding, but you can also use it for hand sanding.
• Silicon carbide sandpaper removes material more quickly than aluminum oxide, but doesn't last as long. Use it on wood, plastic and metal for tasks such as rough sanding, paint or rust removal and sanding between coats when finishing. Use it on drywall to smooth joints. Silicon carbide products often have a waterproof backing that allows you to wet sand. Wet sanding uses liquid to lubricate the work surface, minimizing scratches. This technique also helps prevent the sandpaper from clogging with dust, removes loose abrasive particles and reduces airborne dust.
• Zirconia alumina is suitable for wood, fiberglass, metal and painted surfaces. You'll find it in the form of belts, pads and discs for power sanding. Like garnet and aluminum oxide, the particles break during use, maintaining sharp edges that remove material quickly. However, zirconia alumina lasts longer than aluminum oxide.
• Ceramic alumina is available in belts and discs for power sanding and is good for aggressive material removal on wood. Ceramic abrasives are durable — lasting longer than aluminum oxide.

You may see sandpaper labeled closed-coat or open-coat. Closed-coat products feature abrasives covering all of the backing. This construction removes more material — making it effective for hand sanding — but can clog more quickly than open-coat products. Open-coat products have empty space on the backing, giving waste material room to accumulate without reducing performance. Since they don't clog as quickly, they're effective for power sanding.

Sandpaper Grit Numbers

The grit number of a sanding product indicates the size of the abrasive particles. The lower the number, the larger the abrasive particles — they remove more material but create more noticeable scratches. A higher number indicates smaller particles which don't remove as much material but leave a finer, more polished appearance. Sanding projects use several grit sizes, starting with lower-number grits and moving up the scale to finer, higher-number grits. Each higher grit removes scratches from the previous grit, creating an increasingly smooth surface.

There is a wide range of grit numbers available, from 24 for heavy material removal to 2000 and beyond for working with automotive finishes. Grit numbers between 60 and 220 will handle most household projects.

The specific grit numbers you need vary by project and the material you're sanding, so follow the abrasive product manufacturer's recommendations. Here are some general guidelines:

Grit numbers from 36 to 100 are good for removing material and work well with power sanders. Applications include:

• Stripping away finishes such as paint or varnish
• Removing rust on metals or flaws in wood
• Leveling and shaping wood

Grit numbers from 100 to 180 perform well with both hand sanding and power sanding, preparing bare surfaces for finishes. This range is good for:

• Smoothing work pieces
• Removing scratches
• Final preparation for finishing

Grit numbers from 180 to 320 work for finishing. Hand sanding is good for these applications:

• Removing raised wood grain fibers
• Scuffing between finish coats
