Buying Guides - Sanders


Your guide to buying a sander

For stripping or smoothing large surfaces before re-coating, the right power sander can make the task far more manageable. Various grades of abrasive are available for different materials and finishes - though you may still need to use sandpaper to achieve a really smooth surface (for example, before applying a clear finish). Read our handy guide to help you choose the best power sander for the job.

Belt sander

Ideal for removing a lot of material quickly, this is probably the best tool for sanding large areas such as tabletops, doors and edge sections of timber flooring. It is also good for squaring or shaping wood (for example, sanding doors to fit). It uses a belt of abrasive paper stretched over rollers. Some models can be secured to the workbench for stationary use. A sanding frame is another useful feature, for limiting the depth of sanding.

Orbital sander

An orbital (or 'finishing') sander is the best tool for achieving a smooth finish on large flat areas. It can also be used for smoothing plaster, paint or varnish between coats. The base plate, available in different sizes, moves with a tight, rapid orbital action which minimises scratching.

Random orbital sander

Also described as 'eccentric', a random orbital sander can be the most useful first choice, combining the smoothness of an orbital sander with the speed of a belt sander. It uses circular sanding discs which 'orbit' and rotate simultaneously, leaving the surface virtually scratch-free and distributing wear on the sanding sheets more evenly, so they last longer. A flexible backing pad enables the sander to cope with gently curved surfaces.

Detail or delta sander

Light and easy to handle, this type has a triangular (delta) shaped base for sanding into corners and other tricky areas, making it ideal for fine detail, and for tasks such as preparing panelled doors or irregular shapes (for example, turned stair rails).

Multi-sander

Combining features from both delta and orbital models, this can be used for sanding both flat and contoured surfaces, with special attachments for working on 'profile' sections such as skirting boards and architraves.


Features

Corded or cordless

Most types of sander are corded, but detail sanders are also available in cordless versions, useful for working outdoors.

Variable speed

A variable speed function lets you preset maximum speeds, giving greater control.

Dust extraction

Since sanding can create a lot of dust, a dustbag or vacuum cleaner attachment is a useful facility.
