The best conditions to apply are when there is as little dust or other airborne particles as possible. Clean your work area as thoroughly as possible and allow some time for the dust literally to settle. Consider using a dust collection system or air purifier. When applying a finish with a brush or roller you may notice some bubbles pop up.

Don't panic. Many times these will settle out as the finish dries. If it's a problem, simply use a rag to wipe it down. You can often avoid this by applying a thinner coat. Also, shaking a can of finish will certainly add bubbles, so try stirring instead. After the first coat dries, you'll need to either sand it with fine-grit sandpaper grit or use steel wool.

You may have heard to only use steel wool, but many manufacturers recommend either one. Just be careful not to deeply scratch the finish and certainly do not sand off the finish to the point where you reach raw wood. Wipe off the dust created and apply another coat. A couple of coats are usually enough, but you can apply additional coats more wiped-on coats can be applied than brushed or rolled to create a thicker and more durable finish. Try not to exceed four or five coats of finish.

Choosing a Finish Follow this advice for picking out a proper wood finish. Our expert helps you decide. Drying oils cure through an exothermic reaction between the polyunsaturated portion of the oil and oxygen from the air. Originally, the term "varnish" referred to finishes that were made entirely of resin dissolved in suitable solvents, either ethanol alcohol or turpentine. The advantage to finishes in previous centuries was that resin varnishes had a very rapid cure rate compared to oils; in most cases they are cured practically as soon as the solvent has fully evaporated.

By contrast, untreated or "raw" oils may take weeks or months to cure, depending on ambient temperature and other environmental factors. In modern terms, "boiled" or partially polymerized drying oils with added siccatives or dryers chemical catalysts have cure times of less than 24 hours.

However, certain non-toxic by-products of the curing process are emitted from the oil film even after it is dry to the touch and over a considerable period of time. It has long been a tradition to combine drying oils with resins to obtain favourable features of both substances.

Many different kinds of resins may be used to create a varnish. Natural resins used for varnish include amber , kauri gum , dammar , copal , rosin colophony or pine resin , sandarac , balsam , elemi , mastic , and shellac.

Varnish may also be created from synthetic resins such as acrylic , alkyd , or polyurethane. A varnish formula might not contain any added resins at all since drying oils can produce a varnish effect by themselves. Originally, turpentine or alcohol was used to dissolve the resin and thin the drying oils.

The invention of petroleum distillates has led to turpentine substitutes such as white spirit , paint thinner , and mineral spirit. Modern synthetic varnishes may be formulated with water instead of hydrocarbon solvents. Violin varnishing is a multi-step process involving some or all of the following: primer, sealer, ground, color coats, and clear topcoat. Some systems use a drying oil varnish as described below, while others use spirit or solvent varnish. Touchup in repair or restoration is only done with spirit varnish.

Drying oil such as walnut oil or linseed oil may be used in combination with amber , copal , rosin or other resins. Traditionally the oil is prepared by cooking or exposure to air and sunlight, but modern stand oil is prepared by heating oil at high temperature without oxygen.

The refined resin is sometimes available as a translucent solid and is then "run" by cooking or melting it in a pot over heat without solvents. The thickened oil and prepared resin are then cooked together and thinned with turpentine away from open flame into a brushable solution.

The ingredients and processes of violin varnish are very diverse, with some highly regarded old examples showing defects e. Some violin finishing systems use vernice bianca egg white and gum arabic as a sealer or ground. There is also evidence that finely powdered minerals, possibly volcanic ash, were used in some grounds.

Some violins made in the late 18th century used oxen's blood to create a very deep-red coloration. Today this varnish would have faded and currently be a very warm, dark orange. Most resin or "gum" varnishes consist of a natural, plant- or insect-derived substance dissolved in a solvent, called spirit varnish or solvent varnish.

The solvent may be alcohol , turpentine, or petroleum -based. Some resins are soluble in both alcohol and turpentine. Generally, petroleum solvents, i. The resins include amber , dammar , copal , rosin , sandarac , elemi , benzoin , mastic , balsam, shellac , and a multitude of lacquers.

Synthetic resins such as phenolic resin may be employed as a secondary component in certain varnishes and paints. Over centuries, many recipes were developed which involved the combination of resins, oils, and other ingredients such as certain waxes. These were believed to impart special tonal qualities to musical instruments and thus were sometimes carefully guarded secrets.

The interaction of different ingredients is difficult to predict or reproduce, so expert finishers were often prized professionals. Shellac is a very widely used single-component resin varnish that is alcohol-soluble. It is not used for outdoor surfaces or where it will come into repeated contact with water, such as around a sink or bathtub. The source of shellac resin is a brittle or flaky secretion of the female lac insect, Kerria lacca , found in the forests of Assam and Thailand and harvested from the bark of the trees where she deposits it to provide a sticky hold on the trunk.

Shellac is the basis of French polish , which for centuries has been the preferred finish for fine furniture. Specified "dewaxed" shellac has been processed to remove the waxy substances from original shellac and can be used as a primer and sanding-sealer substrate for other finishes such as polyurethanes, alkyds, oils, and acrylics. Prepared shellac is typically available in "clear" and "amber" or "orange" varieties, generally as "three-pound cut" or three pounds dry shellac to one US gallon of alcohol.

Other natural color shades such as ruby and yellow are available from specialty pigment or woodworker's supply outlets. Dry shellac is available as refined flakes, "sticklac," "button lac," or "seedlac. Shellac clean-up may be done either with pure alcohol or with ammonia cleansers.

Modern commercially produced varnishes employ some form of alkyd for producing a protective film. Alkyds have good solvent, moisture and UV light resistance. Alkyds are chemically modified vegetable oils which operate well in a wide range of conditions and can be engineered to speed up the cure rate and thus harden faster. Better and more expensive exterior varnishes employ alkyds made from high performance oils and contain UV -absorbers; this improves gloss-retention and extends the lifetime of the finish.

Various resins may also be combined with alkyds as part of the formula for typical "oil" varnishes that are commercially available. Spar varnish also called marine varnish was originally intended for use on ship or boat spars , to protect the timber from the effects of sea and weather. Spars bend under the load of their sails. The primary requirements were water resistance and also elasticity , so as to remain adhering as the spars flexed.

Elasticity was a pre-condition for weatherproofing too, as a finish that cracked would then allow water through, even if the remaining film was impermeable. Appearance and gloss was of relatively low value. Modified tung oil and phenolic resins are often used. When first developed, no varnishes had good UV -resistance.

Even after more modern synthetic resins did become resistant, a true spar varnish maintained its elasticity above other virtues, even if this required a compromise in its UV-resistance.

Although their names may be necessarily the best choice for ash, were used in some grounds.

Varnish is a clear transparent hard protective finish or film. It is neither a paint nor stain. In its native state it has little or no color, but may be pigmented as desired, and is sold commercially in various shades. Varnish is primarily used to seal wood finishes where, stained or not, the distinctive tones and grains in the wood are intended to be visible. Varnish finishes are naturally glossy, but satin or semi-gloss sheens are available.
