Wood finishing Wikipedia. Microsoft Project 2010 Portable Gratis. A worker sprays a urethane finish onto a timber. Wood finishing refers to the process of refining or protecting a wooden surface, especially in the production of furniture where typically it represents between 5 and 3. Finishing is the final step of the manufacturing process that gives wood surfaces desirable characteristics, including enhanced appearance and increased resistance to moisture and other environmental agents. Finishing can also make wood easier to clean3 and keep it sanitized, sealing pores that can be breeding grounds for bacteria.

In addition, finishing provides a way of giving low value woods the appearance of ones that are expensive and difficult to obtain. Planning the finish thinking ahead6editFinishing of wood requires careful planning to ensure that the finished piece looks attractive, performs well in service and meets safety and environmental requirements. Planning for finishing begins with the design of furniture. Care should be taken to ensure that edges of furniture are rounded so they can be adequately coated and are able to resist wear and cracking. Careful attention should also be given to the design and strength of wooden joints to ensure they do not open up in service and crack the overlying finish. Care should also be taken to eliminate recesses in furniture, which are difficult to finish with some systems, especially UV cured finishes. Planning for wood finishing also involves thinking about the properties of the wood that you are going to finish, as these can greatly affect the appearance and performance of finishes, and also the type of finishing system that will give the wood the characteristics you are seeking. For example, woods that show great variation in colour between sapwood and heartwood or within heartwood may require a preliminary staining step to reduce colour variation. Alternatively, the wood can be bleached to remove the natural colour of the wood and then stained to the desired colour. Woods that are coarse textured such oaks and other ring porous hardwoods may need to be filled before they are finished to ensure the coating can bridge the pores and resist cracking. The pores in ring porous woods preferentially absorb pigmented stain, and advantage can be taken of this to highlight the woods grain. Some tropical woods, such as rosewood Dalbergia nigra, cocobolo Dalbergia retusa and African padauk Pterocarpus soyauxii, contain extractives such as quinones, which retard the curing of unsaturated polyester and UV cured acrylate coatings, and so other finishing systems should be used with these species. Planning for wood finishing also involves being aware of how the finishing process influences the end result. Careful handling of the wood is needed to avoid dents, scratches and soiling with dirt. Wood should be marked for cutting using pencil rather than ink however, avoid hard or soft pencil. HB is recommend for face work and 2. Trey Songz Intermission 1 And 2.

Care should be taken to avoid squeeze out of glue from joints because the glue will reduce absorption of stain and finish. Any excess glue should be carefully removed to avoid further damage to the wood. Woods moisture content affects staining of wood. Changes in wood moisture content can result in swelling and shrinkage of wood which can stress and crack coatings. Both problems can be avoided by stored wood indoors in an environment where it can equilibrate to a recommended moisture content 6 to 8 that is similar to that of the intended end use of the furniture. Finally, consideration needs to be given to whether the finished wood will come into contact with food, in which case a food safe finish should be used,1. SandingeditSanding is carried out before finishing to remove defects from the wood surface that will affect the appearance and performance of finishes that are subsequently applied to the wood. These defects include cutter marks and burns, scratches and indentations, small glue spots and raised grain. Sanding should not be used to eliminate larger defects such as gouges, and various forms of discolouration. Other techniques are used to remove these defects see below.

The key to preparing a defect free surface is to develop a sanding schedule that will quickly eliminate defects and leave the surface smooth enough so that tiny scratches produced by sanding cannot be seen when the wood is finished. A sanding schedule usually begins with sandpaper that is coarse enough to remove larger defects typically 8. How to end skirting boards Get a neat professional baseboard end.

Our services including tiling, drywall, flooring and moreA typical sanding schedule prior to wood finishing might involve sanding wood along the grain with the following grades of sandpaper, 8. The precise sanding schedule is a matter of trial and error because the appearance of a sanded surface depends on the wood you are sanding and the finish that will subsequently be applied to the wood. According to Nagyszalanczy,1. Conversely, sanding scratches are more easily seen in finer grained, harder woods and also end grain, and hence, they require finer sandpaper 2. The sandpaper selected for the final sanding stage affects the colour of stained wood, and therefore when staining is part of finishing avoid sanding the wood to a very smooth finish. On the other hand, according to Nagyszalanczy if you are using an oil based finish, it is desirable to sand the wood using higher grit sandpaper 4. Scanning Electron Microscopy of 1.

Sanding is very good at removing defects at wood surfaces, but it creates a surface that contains minute scratches in the form of microscopic valleys and ridges, and also slivers of wood cell wall material that are attached to the underlying wood. These sanding ridges and slivers of wood swell and spring up, respectively, when sanded wood is finished with water based finishes, creating a rough fuzzy surface. This defect is known as grain raising. It can be eliminated by wetting the surface with water, leaving the wood to dry and then lightly sanding the wood to remove the raised grain.

These defects should also be removed before finishing, otherwise they will affect the quality of the finished furniture or object. However, it is difficult to completely eliminate large defects from wood surfaces. Removing dents from wood surfaces is quite straightforward as pointed out by Flexner. Add a few droplets of demineralized water to the dent and let it soak in. Then put a clean cloth over the dent and place the tip of a hot iron on the cloth that lies immediately above the dent, taking great care not to burn the wood. The transfer of heat from the iron to the wood will cause compressed fibres in the dent to recover their original dimensions. As a result the dent will diminish in size or even disappear completely, although removal of large dents may require a number of wetting and heating cycles. The wood in the recovered dent should then be dried and sanded smooth to match the surrounding wood.
