Spray guns for wood finishing vary greatly according to the technology in place. For that reason, you cannot just grab your spray gun for automotive to paint wood. There is not a one-size-fits-all solution.<\/p>

So, in this article we are going to explain why they are different, but most importantly, we will share with you 5 spray guns for wood chosen by experts in industrial finishing.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

There are four key reasons why specialized spray guns for wood finishing are recommended. Let\u2019s now consider each one of these reasons.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Wood and metal are different as a surface<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

There are several key differences between wood and metal as a surface. They require different coatings and painting technology.<\/p>

Composition<\/strong>: Wood is an organic, porous material composed of cellulose fibers. Metals are inorganic, non-porous materials that are mined or extracted.<\/p>

Structure<\/strong>: Metals have a crystalline molecular structure while wood has a fibrous grain structure. The grains and patterns in wood are unique to each piece.<\/p>

Hardness<\/strong>: Most woods are softer than metals. On the Janka hardness scale, oak is about 1,300 lbs while stainless steel is around 5,800 lbs (about 2,630.83 kg). Some exotic woods approach the hardness of softer metals.<\/p>

Stability<\/strong>: Wood shrinks\/swells and can warp with changes in moisture and humidity. Metals are dimensionally stable and unaffected by humidity or moisture.<\/p>

Thermal properties<\/strong>: Wood is a poor conductor of heat compared to metals which readily conduct heat. Metals feel cold to the touch unlike wood.<\/p>

Finishing<\/strong>: Wood requires more prep work and finishing like sanding and staining to achieve a smooth appearance. Metals just need cleaning.<\/p>

Weather resistance<\/strong>: When unfinished, wood deteriorates when exposed to weather. Metals resist weathering and oxidize or corrode minimally.<\/p>

Environmental impact<\/strong>: Wood is a renewable resource but metals require mining and refining which can generate pollution.<\/p>

So, in a few words, regarding painting, the porous, fibrous, softer, less thermally conductive nature of wood and its instability require more preparation and finishing compared to metals.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The coatings used for wood vary greatly from those used for, let\u2019s say, automotive refinishing. Here are some of the most common types of coatings used to paint or finish wood:<\/p>

Stains<\/strong>: Used to accentuate the natural wood grain. Come in oil-based, water-based, gel stains. They need a top clear protective coat.<\/p>

Oil-based paints<\/strong>: Provide a smooth, durable glossy finish. Typically contain alkyd resins. Require mineral spirits for cleanup.<\/p>

Water-based paints<\/strong>: Based on latex or acrylic. Easy soap and water cleanup. Less odor than oils. Not as durable.<\/p>

Lacquer<\/strong>: Derived from nitrocellulose. Dries to a very smooth, durable finish. Spray on easily. Requires lacquer thinner to clean.<\/p>

Shellac<\/strong>: An alcohol-based resin secreted from the lac beetle. Classic wood finish. Dries quickly. Requires denatured alcohol to thin and clean.<\/p>

Varnish<\/strong>: Alkyd resins suspended in oil. Forms a hard, protective clear finish. Requires mineral spirits.<\/p>

Polyurethane<\/strong>: Plastic-like protective clear coat. Oil-based or water-based versions. Resistant to scratching and marring.<\/p>

Milk paint<\/strong>: Water-based paint made from milk protein, lime, and pigment. Natural, flat finish. Non-toxic.<\/p>

Exterior paints and stains<\/strong>: Formulated similarly to regular paints and stains, but with additives designed to made the wood withstand weathering. Often oil or latex based.<\/p>

Summarizing this up, oil-based paint, lacquer, shellac, varnish and polyurethane are good options for durable wood finishes. Water-based acrylics work for indoor projects. And stains allow the natural wood to show through.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
