Types of Paint & Finishes: Complete Guide for Coastal Homes
Choosing paint means two decisions: the paint type and the finish. The type sets the base chemistry, while the finish sets the sheen. For coastal NSW homes in Newcastle, both choices affect how long a coating lasts against salt, moisture, and UV.

What are the main types of paint?
Most home paint falls into two families. Water-based acrylic is the modern standard for walls and ceilings. It dries fast, smells less, and cleans up with water. Oil-based enamel is tougher and smoother, so it still suits some trims, doors, and metal. However, water-based enamels now match most of that durability with far less odour.
Beyond those two, a few specialty products matter. Primers and undercoats seal new or patched surfaces so the topcoat bonds well. Ceiling paints are low-spatter and flat. Exterior paints add UV and mould resistance for our coastal climate. For a full breakdown of outdoor products, see our exterior paint types guide.
Understanding sheen levels
Paint finish refers to how much light the dried coating reflects. The spectrum runs from flat (no reflectivity) through low-sheen and satin, up to semi-gloss and high-gloss. Each level has different trade-offs. These cover durability, cleanability, and how the surface looks in different light. For a deeper comparison of each level, see our paint sheen levels explained guide.
Flat and low-sheen finishes — best uses
Flat finishes absorb light instead of reflecting it. So they hide wall flaws and give a clean, soft look. They are the standard choice for ceilings. Low-sheen adds a little more binder, so it cleans better. That makes it the most common wall finish in Australian homes. Neither suits wet areas or high-traffic surfaces.
Satin and semi-gloss finishes — durability and washability
Satin has a soft sheen and good durability. So it suits hallways, kitchens, and children's rooms. Semi-gloss reflects more light and dries to a harder film. That makes it the standard for trims, architraves, skirting, and doors. On the coast, semi-gloss on outside trims also resists moisture and mould better than lower-sheen paints.
Gloss finishes — when to use them
High-gloss suits a few jobs. Think front doors, metal work, and garage doors. These need top durability and a premium look. But gloss shows every flaw. So it demands careful prep and a skilled hand. We rarely use it on interior walls or most cladding.
Choosing the right finish for coastal exteriors
Coastal homes face more moisture and stronger UV than inland ones. So for outside walls here, a satin or semi-gloss topcoat beats a flat finish. The higher sheen sheds water better. It also holds salt for less time. And it is easier to keep clean with routine washing.
Finish selection by surface type — quick reference
- Ceilings: Flat or low-sheen ceiling white
- Interior walls (living, bedrooms): Low-sheen
- Interior walls (wet areas, kitchens): Semi-gloss or satin
- Trims, architraves, skirting boards: Semi-gloss
- Doors: Semi-gloss or gloss
- Exterior walls (coastal): Satin or semi-gloss exterior acrylic
- Exterior trims (coastal): Semi-gloss or gloss exterior
