What this dot point is asking
This dot point asks you to describe common surface finishes and treatments and to explain how they affect a design's appearance, feel, function and durability. A finish is what is applied to the surface of a material after it is made or shaped, and it can transform how an object looks, feels, performs and lasts. You should know the main finishes (matte and gloss, paint and coatings, texture treatments, protective treatments), and be able to explain that finishes are functional as well as decorative. The skill is choosing a finish that suits the design's purpose, not just making something shinier.
The answer
What a surface finish does
A surface finish is a treatment applied to the surface of a material. Finishes serve several purposes at once: they change appearance (colour, shine, texture), alter feel (smooth, soft, textured), improve function (grip, hygiene, glare reduction), and increase durability (protection from wear, moisture and corrosion). A good designer treats the finish as part of the design decision, because the same object can feel cheap or premium, fragile or robust, depending only on its finish.
Matte and gloss
The most basic finish choice is the level of shine. A matte finish is non-reflective, with a flat, soft, understated look that resists glare and hides fingerprints, making it good for premium products and readable surfaces. A gloss finish is shiny and reflective, making colours look richer and images sharper, which suits vibrant, eye-catching work, though it shows fingerprints and can reflect glare. There are also satin or semi-gloss finishes between the two. The choice affects both look and practicality.
Paint and coatings
Paints and coatings add colour and a protective layer. They can give an object a brand colour, a uniform appearance, or a special effect (metallic, soft-touch). Coatings such as varnish, lacquer or powder coating seal the surface, protecting it and changing its feel and shine. Soft-touch coatings, for example, add a pleasant, slightly rubbery feel and better grip. Coatings are a key way to make different materials share a consistent look.
Texture treatments
Finishes can change a surface's texture, not just its colour. A surface might be polished smooth, sandblasted or etched to a matte texture, brushed (as on brushed metal), or embossed with a pattern. Texture affects how an object feels in the hand, how it grips, how light plays across it, and even how it hides wear: a textured finish can disguise scratches and fingerprints that would show on a smooth one. Texture is a powerful, often underused design tool.
Protective and functional finishes
Many finishes exist for function and durability rather than looks. Varnish and lacquer protect wood from moisture and wear; anti-rust coatings and treatments protect metal from corrosion; laminates protect printed paper; anti-glare and anti-fingerprint coatings improve screens; and non-slip finishes improve safety and grip. These finishes extend a product's life and improve how it performs, showing that finishing is an engineering decision as much as an aesthetic one.
Examples in context
Example 1. A premium phone. A high-end phone may use a matte glass or metal back rather than gloss, because matte feels premium, resists fingerprints and reduces glare. The finish choice, more than the shape, makes the device feel expensive and considered, showing finish shaping perceived quality.
Example 2. A wooden chopping board. A chopping board is finished with a food-safe oil that protects the wood from moisture, prevents it cracking, and is safe for food contact, while keeping the natural look and feel. This functional, protective finish extends the board's life, illustrating a finish chosen mainly for durability and safety.
Try this
Cue. Find one matte object and one glossy object and compare how each looks and feels, including fingerprints and glare. Explain which finish suits each object's purpose better.
Cue. Choose a product and identify its finish. List one way the finish improves its appearance and one way it improves its function or durability, showing the finish does both jobs.
Cue. For an outdoor or frequently handled object, recommend a surface finish and justify it against the conditions of use (weather, handling, cleaning, grip). Explain why a purely decorative finish would not be enough.

Original5 marksExplain the difference between a matte and a gloss finish, and describe a situation where each would be the better choice.Show worked answer →
A matte finish is non-reflective, with a flat, smooth, soft appearance. A gloss finish is shiny and reflective.
A matte finish is the better choice where you want an understated, premium or easy-to-read result, for example the body of a high-end product or the pages of a text-heavy book, where glare would be distracting and fingerprints should not show.
A gloss finish is the better choice where you want vibrancy and impact, for example a photographic poster or magazine cover, because gloss makes colours look richer and images sharper, though it shows fingerprints and can reflect glare.
What markers reward: a correct contrast (non-reflective and soft versus shiny and reflective), and an appropriate, justified situation for each linked to readability, vibrancy or feel.
Original5 marksExplain three reasons a designer might apply a surface finish to a product, giving an example for each reason.Show worked answer →
Three reasons, each with an example:
To improve appearance. A finish can add colour, shine or a premium look, for example painting a product in a brand colour with a smooth gloss.
To protect and increase durability. A finish can guard against wear, moisture or corrosion, for example a clear lacquer or varnish on wood, or a coating on metal to prevent rust.
To change the feel or function. A finish can alter texture or grip, for example a soft-touch coating that feels pleasant and improves grip, or a textured finish that hides scratches.
What markers reward: three distinct reasons (appearance, protection/durability, feel/function) each with a sensible example, showing that finishes are functional as well as decorative.
