Solid Wood – Product selection The world of plants, which includes trees and shrubs, is one of huge variety. There are between 30,000 and 40,000 different kinds through out the world, of which around 500 types of wood are processed to make furniture and wood-based materials. For the sake of simplicity, we have divided the different varieties of trees into hardwood, softwood and wood containing resins and oils. Each type of wood being processed is made up of different content depending on where it was grown, and these affect both the wood’s physical and mechanical properties when being machined. These factors are critical for the finishing process: woods that contain high levels of resins (spruce, pine) or oils (teak) are sanded using a product with an open grit coating in order to obtain a perfect surface. In the case of wood that contains some mineral content, a product with a silicon carbide grit should be selected.

Hardwood Because of its fibrous nature and close vascular structure, hardwood is a strong, heavy wood. Its slow rate of growth makes the wood dense and hard and thus difficult to finish.
Wenge
Sipo
Ramin
Birch
Softwood Wood that is lighter than hardwood is cate gorised as softwood. It grows more quickly than hardwood and has a looser, open vascular structure. This wood is therefore softer and more sensitive to pressure but is easier to finish.
Redwood
Wood containing resins or oils Both hardwoods and softwoods can contain resins or oils in their cellular structure. These protect the tree from extreme weather conditions and help it to heal after physical damage. The oils and resins, however, adversely affect the wood’s sanding properties.

Wood-based materials – Product selection Wood-based materials are made up of layers of wood of different strengths or strips,chips or fibres of various types of wood. Pressed-wood materials are created by bonding a mixture of different forms of wood particles with natural and/or synthetic adhesives.
Materials
Plywood consists largely of veneers The term plywood refers to sheets of wood made up of a number of layers of veneer glued one on top of the other. Each layer is rotated through 90° before being glued down to the layer beneath. The grain on the two visible sides runs parallel so there is usually an uneven number of layers. Plywood can be obtained in various kinds of wood and should be finished with an abrasive appropriate to the relevant wood; only the outermost layer is sanded, and this contains no adhesive. Plywood is used mostly for making furniture, models and also for interior finishing.
Chipboard consists largely of wood chips Chipboard is a subgroup of wood particle board. It is a flat, compressed sheet with a surface made of especially fine-grade chips. It is made by gravity- or air-spreading processes, and during its manufacture there is a gradual transition from the coarse-grained inner layer to the fine-grained outer layer. Chipboard is in most cases veneered or covered with an outer coating. Because the edge faces of chipboard are very rough, these are rarely finished and are usually covered, for instance with an edging of solid wood.
MDF consists largely of wood fibres MDF (medium-density fibreboard) is a sheet material made from wood fibres. MDF’s technical properties make it one of the world’s fastest-growing wood products. Based on finely crushed fibres of conifer wood, usually without bark, and produced by a gentle compression process, the result is a wood product which is consistently homogeneous in both its length and width. MDF board is very easy to work with and is highly versatile in its applications. It is often used as base panels for flooring and in the furniture industry, where the ability to finish its edges is a highly desirable property.

Varnishes – Product selection A varnish is a coating material in liquid or powder form which is applied to surfaces in thin layers. A continuous film is obtained by applying chemical or physical pro cesses (e.g. solvent evaporation).
Materials
The main types of varnish in current use are:
UV-hardened varnishes
• Solvent-free • Approx. solids content 99 % • UV curing leads to a short processing time • Thin varnish layer (furniture industry) • Work pieces usually flat, varnish frequently applied by roller on production line
UP (polyester) varnishes
• Normally a 2-component system hardening started with a crosslinking additive • Approx. solids content 90 % • Thick varnish layers possible • Minimal varnish shrinkage • Very hard, robust varnish • Intermediate sanding best with coarse sizes (P150 – P240), giving improved adhesion
Water-based varnishes
• Water used as thinner • Approx. solids content 30 – 40 % • Drying is a physical process, curing partially a chemical process • Drying time somewhat lengthy and more difficult to control • Wood fibres raised by water absorption • Usually thermoplastic • Sanding material tend to clog easily
NC (nitrocellulose) varnishes
• Contains solvent • Approx. solids content 20 % • Drying is a physical process • Thin layers • Thermoplastic • Scratches from sanding in wood and varnish quickly visible
PUR (polyurethane) varnishes
• Contains solvent • Approx. solids content 30 – 40 % • Drying is a physical process, curing is a chemical process • The better the varnish has set, the lower the tendency to clog
Oil/wax
• Natural wood protection, e.g. linseed oil (impregnation) • Oil is absorbed by the wood, filling up the cell cavities • Does not form a film

Tips The following points must be followed in particular for a perfect surface: • Always follow the recommendations of the varnish manufacturer. • Always use an aggressive abrasive. A blunt grit presses the wood fibres together instead of sanding them off. • Apply low pressure and choose the correct abrasion speed (see the chapter on belt sanding, page 35). • The higher the gloss from the varnish, the more readily scratches show up in the wood and varnish. Thus finish with fine-grade sanding. • Always cross-sand assembled work pieces (mitres). • On difficult veneers, sand with a grit size 1– 2 grades finer than usual. • The final sanding pass prior to varnishing must always be made in the direction of the grain to avoid crosswise scratches becoming visible after varnishing.

Tips During intermediate sanding of varnish on wide-belt machines, please note the following: • Always follow the recommendations of the varnish supplier. • Sanding with a padded belt gives better results than a contact belt. • The use of an efficient dust-extraction system reduces dust on the work piece and prevents premature clogging of the abrasive. • Also recommend is the use of a blower system to clean the belt during sanding. This significantly prolongs belt life. • Using only as much pressure as necessary reduces overheating of the varnish to a minimum and thus significantly improves the surface quality of the work piece and considerably prolongs abrasive life. • Adjust the feed speed (8 –15 m/min) to suit the operation and varnish system to prevent surface overheating and reduce belt clogging. • Optimum sanding speed for varnish sanding is between 3 and 15 m/s. • Cross-sanding is recommended in order to achieve the most even finish possible (cross/pad sanding).

Types of abrasives
Flexible abrasives Classic flexible abrasives and complete finishing systems for conventional surface treatment on all types of materials. The basic construction is based on a flexible backing layer. The grit is initially fixed by using a base coat on the flexible backing. The second application of adhesive, the size coat, is made following a drying process and secures the grit more firmly to the backing. Other coatings may be added on top of the size coat. These consist mainly of substances to reduce early choking or clogging of the abrasive during the sanding process or of chemicals which provide a cooling effect during hard sanding on metal-based materials.
Nonwoven abrasives Products for preparatory and cleaning work as well as structuring, usually without changing the geometry of the work piece. In a continuous process, the fibres are carded, layered and needlepunched to form a nonwoven fabric. The resulting fine polyamide fibre forms a 3-dimensional backing. In a subsequent process it is sprayed with a blend of bonding agents and grit which penetrates into the fabric.
Foam-backed abrasives Foam-backed sanding blocks in the widest possible variety of shapes and grades for precision finishing of wood, fillers, paint and varnish. In a special process, polyurethane is made into large foam blocks which form the basis of the foam backing. The blocks are then further processed into sheets and strips. Afterwards, a thin layer of adhesive is applied in a spraying process. In a final processing stage, the grid is applied in multiple coating stages.

The most common materials used to make abrasive grit today are the synthetic minerals aluminium oxide and silicon carbide in their various forms. There is also a growing use of special minerals such as zirconia alumina, ceramic aluminium oxide and diamond. The use of natural minerals like garnet and emery, however, is rapidly declining. The grit’s hardness and toughness, which are a function of the minerals used, determine the properties and applications of the abrasives.

Flexible abrasives
siasoft – for optimum pressure distribution The optimum pressure distribution provided by the foam backing gives optimum sanding. Pressure from each fingertip is spread more evenly over the entire surface, thereby avoiding isolated deep scratches. Clogging is reduced, there is less danger of sanding through the varnish, and the finish is finer and more uniform.
Pressure distribution using conventional abrasives without siasoft, e.g. sandpaper sheets

When using a random orbital sander, take care to ensure that the most suitable backing pad is used. Soft or extra soft backing pads are recommended for intermediate sanding on varnish. For dust-free operation, we recommend the use of a powerful dust-extraction system. Because very little material is taken off when sanding on varnish, this operation should be carried out with care. When using machines, apply only a low pressure to keep sanding faults to a minimum.
15-hole backing pad – for every purpose We developed our 15-hole air-chamber backing pad on the basis of our renowned air-chamber technology used in industries throughout the world. It allows 6-, 7-, 9- and 15-hole discs to be used with one and the same backing pad, which provides major savings in the storage of different pads. Thanks to its ingenious system, the 15-hole backing pad can be used on all current orbital sanding machines. The 15-hole backing pad is available in hard, soft and extra-soft grades. Advantages and properties • suitable for use on 6-, 7-, 9- and 15-hole discs • air-chamber system available in three hardness grades • high-suction centre hole gives outstanding dust removal • special adapters for compatibility with all common orbital sanders • low vibration (discs and adapters are weight-optimised)

Antistatic finish Static charges
Antistatic effect
Any material-removal process generates friction and static charges, resulting in a positive or negative electrostatic voltage on the work piece and belt (kV/m). If these charges cannot be conducted to an earth ground, then the belt, the work piece and dust all become statically charged.
However, if sanding belts are used which contain carbon fibres, soot, graphite and/or dissolved salts (electrolytes) in the paper and/or adhesive, such static voltages can be grounded through contact points on the machine such as drive or guide rollers.
This charging process causes dust from the sanding process to stick like a magnet to the work piece and the machine, an effect made worse by using abrasives that have a low-grade antistatic finish. The result is a greater need for cleaning and, at the same time, a reduction in belt life.
Without antistatic finish
Effects and advantages of an antistatic finish • Conductivity releases/neutralises dust • Optimum dust removal • Longer belt life • Clean work piece surfaces and edges • Clean machinery • Improved surface quality
34
Paper, fabric and abrasive grit are insulators rather than conductors, so it is the abrasive’s construction which determines whether or not a belt’s antistatic properties are effective or not. For this reason, only the very best products are awarded the TopTec seal of quality.

Optimum grit sequence
Using the optimum grit sequence during the sanding process not only gives better sanding results but is also important in achieving the most economical surface treatment. For this reason it is important never to skip more than one grit size at one time!
For example:
P040
P060
P080
P100
P120
P150
P180
P220
The main exceptions to this are given below: From
