Wood Finishing in Northern Virginia

at | Category: Wood Finishing


Wood in its natural form cannot be used as it is. It needs lots of cosmetic changes to it before it can be supplied to the market. Northern Virginia wood finishing is one such change. The process of embellishing or protecting the surface of any wooden material means “Wood finishing ” Generally, it starts with the surface preparation which is done by sanding by hand, scraping or planing. Holes and Imperfections are filled with wood filler. Quite often the wood color is changed by staining, bleaching and number of other such methods. Once the wooden surface is prepared and stained, several numbers of coats of finish are applied. Often sanding between the coats. Finishing takes several hours to complete.

The most common Northern Virginia wood finishes include wax, shellac, tung oil or linseed oil, lacquer, varnish or paint. Other finishes called Oil Finish are actually just thin varnishes with relatively larger amount of oil and solvent. Very rarely water based finishes are used, because they cause ” raising in the grain ” wherein the surface fuzz emerges and requires sanding down. Finally, the surface may be polished or buffed using steel wool, pumice stone or rotten stone. Other polishing and rubbing compounds are also used depending on the shine desired. Mostly, whatever way the polishing is done, a final coat of wax is applied over to add protection to the wooden item

The Finishing of wood does not involve any special material. Any old rag, or a rubbing pad or spray guns can be used for applying wood finishes over the wood. The processes and the terminology involved are different in different parts of world. For example, the process of replicating the look of traditional French polished wood is more commonly done in the UK by “pulling over” precatalysed lacquer, within 24 hours of spraying, whereas in the U.S. a “rubbed” finish is more common. There are, in general, three types of finish viz… evaporative, reactive and Coalescing. Different types of wood need a unique way of finishing. We advice you to consult a expert carpenter.

In Evaporative Finishing, alcohol, acetone and nitro-cellulose lacquer thinners are used as solvents and thinners. Shellac and nitro-cellulose lacquers fall into this group.

In Reactive finishes, solvents like white spirits and naphtha are used. Linseed oil and oil varnishes are reactive finishes which change chemically when they cure, unlike evaporative finishes. Tung oil and linseed oil are reactive finishes.
