Sanders are used to sand wood and similar products, painted surfaces,
metal, stone, etc. There are sanders of various different shapes in order
to do specific jobs:
- The delta sander or triangular sander ideal for restoration work such as the sanding
of shutters (louvre shutters) or staircases. Thanks to its shape, it can get into tight
angles. It is compact and easy to use.
- The vibrating sander recommended for sanding flat surfaces such as doors or furni-
ture. Move the sander slowly and regularly, in the direction of the wood fibres.
- The orbital sander which enables you to sand, buff or polish, using the suitable
accessories. It is precise and manoeuvrable, and can be used on surfaces that are not
flat. It is a very versatile machine. Move the sander with slow and regular circular
movements.
- The belt sander is used to take off much more material and to sand wide surfaces
such as wooden floors. The belt moves longitudinally and sands this way. Therefore,
work in the direction of the wood fibres, without pressing down on the machine. Hold
the machine tight, because it is a powerful tool. Attention, if you leave the tool in one
place, there is a risk that you will carve out a hollow in what you are sanding.
When you are positioning the abrasive belt, ensure that it does not block the inlet
holes (if the machine has any)
Generally speaking, it is better to begin with coarse grain sandpaper (e.g. A40) and
move up to finer grained papers (e.g. A120). The basis weight is inversely proportio-
nal to the abrasive power.
The adjustment of the speed, if you machine has this equipment, enables you to adapt
the speed of vibration to the material you are working with. For example, you need
to use a low speed for stripping, in order to prevent heating or liquidising the paint,
which would damage the sandpaper.
It is better to hook your machine up to a vacuum cleaner in order to collect as much
dust as possible
