The Use of Finishes

The Use of Finishes

Reasons for Using Finishes

  • Finish application serves various purposes aimed to enhance and better a product’s functionality, aesthetics, and longevity.
  • They offer additional protection against environmental factors such as moisture, corrosion, UV radiation, and general wear.
  • Finishes can enhance a product’s aesthetics, improving its appearance and feel, often a driving factor in consumer choice.
  • Applying specific finishes can create specific textures or visual effects on a product.
  • They can also serve functional purposes, such as increasing grip or reducing reflectivity.

Types of Finishes

  • Paints and varnishes offer an extensive colour range, with options for matt or gloss effect. They are flexible and used on a variety of materials.
  • Oil finishes (like linseed oils) are used on materials like wood to provide a warm, natural sheen, along with resistance to water and dirt.
  • Lacquers provide a high-gloss finish and are used on metals and woods to prevent tarnishing and scratching.
  • Powder coating is a technique used on metals, providing a durable and corrosion-resistant surface.
  • Plating (such as gold, silver, or chrome) can provide a high-quality finish as well as corrosion resistance.

Application of Finishes

  • The method of application depends upon the type of finish. It could be applied by brush, spray, dipping, or by using a cloth.
  • Preparation of the material before application is key. The surface may need to be cleaned, smoothed, or primed.
  • Each type/specifications of finish will come with a set of manufacturer’s instructions that must be followed for best results.
  • Multiple coats may be required to achieve the desired result. This often involves applying a layer, allowing it to dry, and then lightly sanding before applying the next layer.

Post-Application Care

  • Following application, finishes often need a specified time to cure or harden right.
  • They may require ongoing maintenance such as cleaning, buffing, or the application of further layers over time.
  • Long-term care can include repair or restoration if the finish becomes damaged.

Understanding the range and purposes of finishes will enable you to suggest appropriate finishes in your own design work, whether for protection, aesthetic, or functional reasons.
