Without the proper finish, the wood may crack, dry, swell (exposure to moisture), and deteriorate. However, although the primary goal of each type of wood finish is to add a protective layer, it can also help improve the aesthetic attraction of the wood.

Each type results in a unique appearance and protection, making it necessary to choose the right type of finish.<\/p>\n<p><strong style=\"font-size: 1.4rem;\">Penetrating Finishes<\/strong><\/p>\n<p>Penetrating <a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/search?k=%22Wood+Finishes%22&amp;st=31&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Wood_Coatings&amp;utm_term=2024PC&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">wood finishes<\/a> offer a more natural look as they enter deep into the surface of the wood. You may have to use a cloth to add a protective layer of wood oils to ensure better sheen and surface penetration.<\/p>\n<p><strong>Linseed Oil<\/strong><\/p>\n<p><a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/Product\/search?k=Linseed+Oil&amp;st=31&amp;so=k_0&amp;sl=359471663\" target=\"_blank\" rel=\"noopener\">Linseed oil<\/a>, which comes from flax plant seeds, is an easy to apply wood finish, also with a brush or cloth. However, curing may take longer. It soaks into the pores, resulting in a shiny appearance. Linseed oil enhances natural appearance. A downside is that it darkens with age, but it is ideal for firearm stocks, surfboards, etcetera.<\/p>\n<p><strong>Tung Oil<\/strong><\/p>\n<p>Obtained from the nut or seed of the tung tree,\u00a0<a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/search?k=%22Tung+Oil%22&amp;st=31&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Wood_Coatings&amp;utm_term=2024PC&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Tung oil\u00a0<\/a>is one of the most universal penetrating finishes. It is an environmentally-friendly wood finish and relatively safe when completely cured. It is ideal for boat decks and floors, and results in a light satin look with a slight golden tint. It generally is applied with a cloth or brush.<\/p>\n<hr \/>\n<h3>Introducing ULTRUS<sup>TM<\/sup>, a brand for UL Solutions powerful software to manage regulatory, supply chain and sustainability challenges. <a href=\"https:\/\/www.ul.com\/software\/ultrus?utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Wood_Coatings&amp;utm_term=2024PC&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Explore now<\/a>.<\/h3>\n<hr \/>\n<p><strong>Cedar Oil<\/strong><\/p>\n<p>Known as\u00a0cedarwood oil, this wood finish has a characteristic woody odor. Cedar has a natural resistance to insects, disease, and rot resulting from exposure to moisture or water, which makes it desirable in exterior applications particularly on facades and siding. It has a warm, hand rubbed and natural appearance which is also ideal for polishing and furniture. An undesirable trait is that it becomes light silvery gray when fully weathered.<\/p>\n<p><strong>Danish Oil<\/strong><\/p>\n<p>It is a mixture or oil (usually <a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/search?k=%22Tung+Oil%22&amp;st=31&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Wood_Coatings&amp;utm_term=2024PC&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">tung oil<\/a> or boiled <a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/Product\/search?k=Linseed+Oil&amp;st=31&amp;so=k_0&amp;sl=359471663\" target=\"_blank\" rel=\"noopener\">linseed oil<\/a>), varnish, and thinner.\u00a0Danish oil\u00a0offers better surface protection than plain\u00a0oil\u00a0wood finishes.\u00a0It is relatively easy to apply and moderately durable. It does enhance the natural appearance of wood, and it&#8217;s typically used for wooden utensils and handles. It results in a buffed to matte finish or gloss, and is applied using previous methods cited.<\/p>\n<p><strong>Surface Finishes<\/strong><\/p>\n<p><a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/search?k=%22Surface+finishes%22&amp;st=31&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Wood_Coatings&amp;utm_term=2024PC&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Surface finishes<\/a> are applied on the top of the wood to create a protective layer. This type of wood finish makes an outstanding choice for furniture and materials that are exposed to much news and therefore wear and tear.<\/p>\n<p><strong>Shellac<\/strong><\/p>\n<p><a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/search?k=%22Shellac%22&amp;st=31&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Wood_Coatings&amp;utm_term=2024PC&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Shellac<\/a> wood finish\u00a0looks very attractive on wooden objects made from walnut, fine veneer, and mahogany. However, it is not durable and dissolves in water and solvents like alcohol. In recent years, water based shellac has been developed but it is not anymore durable then alcohol based shellac. Shellac results in a fine finish that accentuates the natural grain of the wood. It can be rich orange to super blonde, and can be used on a variety of substrates. We are discussing wood finishes here, but shellac does an excellent job of smoke and fire stain suppression.<\/p>\n<p><strong>Lacquer<\/strong><\/p>\n<p><a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/Applications\/19534\/Wood-and-Furniture-Coatings\/search?k=%22Lacquer%22&amp;st=31&amp;so=k_0&amp;sl=359485819&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Wood_Coatings&amp;utm_term=2024PC&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Lacquer<\/a>\u00a0is a combination of different shiny wood finishes. Lacquer is used in many cases when it really isn&#8217;t known what the finish is and really can be a misnomer. For example, you can find lacquer wood finish based on shellac, <a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/Applications\/19534\/Wood-and-Furniture-Coatings\/search?k=%22Nitro+cellulose&amp;st=31&amp;so=k_0&amp;sl=359489023&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Wood_Coatings&amp;utm_term=2024PC&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">nitro cellulose<\/a>, and urushiol, among others. Usually, the drying process involves solvent evaporation, resulting in a hard and durable finish. The appearance is dull, medium to high gloss. Ideally used for wooden furniture such as cabinets, doors and shelves. <a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/Applications\/19534\/Wood-and-Furniture-Coatings\/search?k=%22Nitro+cellulose&amp;st=31&amp;so=k_0&amp;sl=359489023&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Wood_Coatings&amp;utm_term=2024PC&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Nitro cellulose<\/a> was the most popular furniture finish for many years. It has a distinction of being able to rewet the coated substrate if a mistake is made in finishing. Water based lacquers have suffered in this regard.<\/p>\n<p><strong>Varnish<\/strong><\/p>\n<p><a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/Formulations\/4892\/Wood-Coatings\/search?k=%22Varnishes%22&amp;st=31&amp;so=k_0&amp;sl=359486581&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Wood_Coatings&amp;utm_term=2024PC&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Varnishes<\/a> are generally a more complex coating, as it is a clear and transparent wood finish that usually comprises drying oil, resin, and thinner or solvent.

Varnish like lacquer, is used interchangeably for many finishes when either the person using the word, knows what the finish is or not.

However, you can find wax finishes with practically any type of wax currently.\u00a0Wax furniture finish\u00a0is easy to apply and offers some abrasion resistance.
