Choose the right wood coating to extend the life of your surface

Wood is a wonderful, versatile building material that has been used for thousands of years to construct everything from walls and floors of the family home to the furniture and cabinetry that fill it – also in Singapore. In order to keep wood functioning at its best and most beautiful, it needs to be protected from abrasion, chemicals, moisture, UV radiation, weathering, and attack from microbes such as fungi and mould. This is the job of wood coating. With such a wide range of substrates (hardwood, softwood, MDF, aged wood, or green wood) and applications (exterior, interior, furniture, building, residential, industrial) it is no surprise that wood coating is a billion dollar industry with a glut of players and products.

In this article we provide an overview of wood coatings technologies and products, and the big brands and companies that make up the industry. As well as traditional coatings such as stains and varnishes we look at newer technologies such as powder coating, polyurethanes, and specialised wood coatings.

Shellac, lacquer, stain and varnish – Common wood coatings in Singapore

The type of suitable wood coating is defined by the end use of the substrate.

Varnishes, shellacs, stains, lacquers, polyurethanes, epoxies, and other wood finishes all have properties which work best when paired with the right application. Which wood coating you need depends on the type of wood and the end use of the substrate. A lot of these terms are used to refer generally to a finish, even though they denote specific finishes. Below is a brief description of different wood coating types popular  in SIngapore and their properties.

  • LACQUER – Lacquer is a form of finish in which the resin is dissolved in a solvent (unlike shellac which uses alcohol). It is harder than shellac, and is used to give a clear or coloured shiny, glossy finish for furniture. The high VOC content in wood lacquer makes it a less  popular option than water-based varnishes. These are also used for protecting and finishing wooden floors such as parquet.
  • VARNISH – A wood varnish is a transparent protective finish that dries hard and usually glossy (though they can be matte or semi-gloss). The basic components of varnish are a drying oil, resins, and a solvent, and the resin can be acrylic, oil, polyurethane, epoxy, and others. A varnish is a hard-wearing finish which is suitable for both indoor and outdoor use as it is waterproof, durable, tough, and versatile.
  • STAIN – A wood stain is a coating which consists of dyes or pigments dissolved in a vehicle with a small amount of binder. When applied it soaks into the wood substrate and, depending on whether it is transparent or opaque, accentuates the wood grain or flatten out the wood with a colour. Stains are used to give wood a particular colour, and not for protective properties. If protection is needed a clear varnish is often applied over the top.
  • SHELLAC – A shellac is a softer form of finish which uses naturally-occurring resin (the shellac) dissolved in ethanol to provide a colour and high-gloss finish for wood products. Shellac is now mostly used for furniture and instruments as it is not as durable as varnish, and alcohol spills will cause the shellac to dissolve.

A quick look into the wood coating process

Whether using paint, varnish, or stain it is important to use the correct application methods and processes. A primer cannot be used as a final topcoat, and though some topcoats can be applied as all-in-one systems, not all can.

Preservatives as industrial wood coating

Impregnation is a wood preservation method where protective chemicals are ‘impregnated’ into timber through the application of pressure. It makes the timber more durable and protects it from pests such as mould, fungi and insects. The preservatives are copper-based (a natural biocide), sodium silicate, thinned epoxy resins (preservative and sealer in one), or oil-based (coal-tar creosote). There are also fire-retardant impregnation chemicals which reduce the surface spread of flame, heat, and smoke.

Impregnation is an industrial wood coating treatment used to protect telegraph poles, railway sleepers, outdoor structures such as decks and playground equipment, as a building material in domestic, commercial, and public buildings, and more.

Finishing the protective system with primers to topcoats

When it comes to wood coatings, the intended end use of the wood is vital for choosing the coating system. Exterior wood needs all the protection it can get, and a primer not only protects the wood from the environment, but also prevents cedar bleed and tannin stain – where the tannins from the wood are drawn to the surface and stain the paintwork. Acrylic sealing primers are one such coating, that both seals and protects. A primer also works to connect the wood substrate with the coating, ensuring adequate adhesion.

Surface finishes are those that do not penetrate the wood. Decorative paints, varnishes, lacquers, and shellacs are surface finishes, and so they dry to form a protective film on top of the wood. A clear topcoat protects the layers beneath while enhancing the final finish and providing abrasion and stress resistance. When working with a stain (which is a penetrative coating), a varnish or other surface coating will enhance and protect the colour.

Latest developments and inventions in the wood coatings market

Wood coatings are not just about protecting the substrate while letting the beauty of the wood shine through. With technologies improving all the time, it is possible to powder coat wood substrates now, as well as protecting them from fire or making a deck anti slip. Below is more information on these specialty wood coatings.

  • Wood powder coating – Powder coating is the process of using electrostatic charge to cause a dry powder to adhere to a substrate and then baking and curing the powder in an oven. The resulting coating is immensely durable and attractive, as well as being environmentally friendly due to the lack of solvent. Powder coating wood is now gaining widespread popularity, particularly for coating furniture.
  • Fireproof systems for wood – Fire is one of the greatest dangers for wood. There are two coatings that act as passive fire protection measures for wooden substrates: intumescent and fire retardant coatings. Intumescent coatings swell up in the presence of extreme heat, forming a protective layer of char between the wood and the fire. Fire retardant paints work by releasing flame-damping gases to prevent ignition.
  • Making wood slip resistant – Wood surfaces can be very slippery when wet, whether decking, stairs, ramps, or walkways. Anti skid paint works through the inclusion of a non-slip aggregate or by creating a rough surface that provides more grip in wet or dry conditions.

    May I know how to waterproof a part of my toilet wooden door frame which gets splash with water as it’s beside a face basin? Thank you.

      Dear Stewart,

      A nano coating or polyurethane high gloss wood lacquer applied to the wooden frame of your door should provide the waterproofing properties you seek. Whichever coating you use, always apply according to the manufacturer’s instructions, and make sure your door frame is dry and clean before application. Nano coatings are applied by spray or wipe on applications, while lacquers and varnishes commonly use a brush.

      Best regards,

      Dear Sum,

      Thank you for your interest in wood coating. For your project we would recommend you use an interior wood stain with a matt finish. These products can be used to transform your pine into a darker colour, bring out the natural wood grain, and provide a range of finishes. There are a number of brands that provide wood stains including Osmo, Ronseal, and Woodmax Paint. Head to your local hardware store to check out the full range. Good luck with your project!
