Lacquer thinners, also known as cellulose thinners do come in different flavours, e.g., 'hot' or 'fast' thinners and 'cool' or 'slow' thinners depending on how the formulation is meant to perform. lacquer thinners will soften cured lacquer, and alcohol softens cured shellac.Ĭellulose polishes and thinners and lacquer and lacquer thinners are in the same family of finishes. The solvent will re-soften the film, e.g. Successive layers burn in to one another and form a contiguous whole. The solids are soft and string-like in solution but as the solvents evaporate they lock together in a solid mass like dried spaghetti. Nitro-cellulose lacquers and shellac fall into this group.

Check with your reseller or manufacturer for up-to-date details. Timber finishes are constantly being improved and new options developed. For instance, the process of replicating the look and feel 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. The processes involved and the terminology for the materials used are quite different in Britain than the processes and terms used in the USA. Special tools used to apply wood finishes include rags, rubbing pads, brushes and spray guns. Often, a final coat of wax can be applied over the finish to add a slight amount of protection.įrench polishing is not polishing as such, but a method of applying many thin coats of shellac using a rubbing pad, yielding a very fine glossy finish. Water-based finishes can cause what is called "raising the grain" where surface fuzz emerges and requires sanding down.įinally the surface may be polished buffed using steel wool, pumice, rotten stone and other polishing or rubbing compounds depending on the shine desired. Other finishes called "oil finish" or "Danish oil"are actually thin varnishes with a relatively large amount of oil and solvent. Commonly used wood finishes include wax, shellac, drying oils (such a linseed oil or tung oil) lacquer or paint. Once the wood surface is prepared and stained, a number of coats of finish may be applied, often sanding between coats. Gel stains can also be used to avoid blotching. To avoid blotching, a barrier coat such as shellac or a conditioner should be applied before the stain. Note that some woods such as pine or cherry do not absorb stain evenly, which results in "blotching". Imperfections or nail holes on the surface may be filled using wood putty or pores may be filled using wood filler, the wood's colour is changed by a variety of techniques that typically involve staining, bleaching or ammonia fuming. The process starts with surface preparation, either by sanding, scraping, or planing. Timber finishing refers to the process of embellishing and/or protecting the surface of a wooden material.
