Walk into any paint store in New Zealand and you'll quickly notice a wide range of price points on the shelves. The difference between a budget tin and a top-shelf product isn't just marketing — it comes down to real differences in ingredients, performance, and how easy the paint is to work with. Understanding these differences can save you time, money, and frustration on your next painting project.
What Makes a Paint "Trade" Grade?
Trade paint is formulated primarily for professional painters who apply large volumes regularly. These products are designed to be efficient and consistent, but they typically use a lower concentration of pigment and binders compared to premium options. Trade paints are widely available at paint specialists and hardware stores like Bunnings and Mitre 10.
Key characteristics of trade paint:
- Lower pigment load — may require more coats to achieve full, even coverage
- Thinner consistency — easier to apply quickly over large areas
- Adequate durability for lower-traffic areas or surfaces that will be repainted regularly
- Lower upfront cost per litre
Trade painters often choose these products because they can apply them efficiently and factor repainting into their service schedule.
What Makes a Paint "Premium" Grade?
Premium paint contains a higher concentration of quality pigments, binders (usually 100% acrylic), and additives that improve performance. Brands like Resene and Dulux offer premium ranges specifically engineered for superior coverage, washability, and longevity.
Key characteristics of premium paint:
- Higher pigment and binder content — better hide and coverage, often in fewer coats
- Superior washability — stands up to scrubbing, ideal for kitchens, bathrooms, and hallways
- Better adhesion — less likely to peel or crack over time
- Improved flow and levelling — reduces brush marks and roller stipple for a smoother finish
- UV resistance — particularly important for NZ's high UV environment, especially in exterior applications
Coverage: The Real Cost Comparison
One of the biggest misconceptions is that premium paint is simply more expensive. In reality, when you factor in coverage per litre and the number of coats required, premium paint can be comparable in cost — or even cheaper — than trade paint over the life of a job.
| Feature | Trade Paint | Premium Paint |
|---|---|---|
| Cost per litre | Lower | Higher |
| Coats typically needed | 2–3 | 1–2 |
| Coverage per litre | Lower | Higher |
| Washability | Moderate | High |
| Durability / lifespan | Moderate | Long |
| Finish quality | Good | Excellent |
| Best for | Large commercial jobs, frequent repaints | High-traffic areas, long-term results |
As a rough guide, premium paints often cover more square metres per litre than trade equivalents — always check the technical data sheet for the specific product you're considering.
NZ Climate Considerations
New Zealand's climate varies enormously — from the humid, wet conditions of Auckland and Northland to the harsh UV exposure of Central Otago and the salt-laden air of coastal areas. BRANZ research consistently highlights that exterior paint systems in NZ face significant weathering stress, making paint quality a critical factor for exterior work.
For exterior surfaces, investing in a premium paint with strong UV and moisture resistance is generally worthwhile. For interior low-traffic areas like spare bedrooms or ceilings, a quality trade paint may be perfectly adequate.
Sheen Levels and Where to Use Them
Both trade and premium ranges come in various sheen levels — flat/matte, low sheen, semi-gloss, and gloss. The sheen level affects both appearance and durability:
- Flat/matte — hides surface imperfections, best for ceilings and low-traffic walls
- Low sheen — a popular all-rounder for living areas and bedrooms
- Semi-gloss / gloss — highly washable, ideal for trims, doors, kitchens, and bathrooms
In wet areas like bathrooms, look for products specifically formulated to resist mould and moisture — this is especially relevant under the Healthy Homes Standards for rental properties.
Which Should You Choose?
Here's a simple way to decide:
- Choose trade paint if you're painting a low-traffic area, working to a tight budget, or the surface will be repainted within a few years.
- Choose premium paint if you want a long-lasting result, are painting high-traffic or wet areas, or you want the best possible finish with fewer coats.
For most homeowners doing a full interior or exterior repaint, premium paint is usually the better investment — the improved coverage and durability mean you'll repaint less often and get a better-looking result.
Tips for Getting the Best Result
- Always use the correct primer for your surface — even the best topcoat won't perform well over a poorly prepared surface.
- Follow the manufacturer's recoat times — rushing between coats is one of the most common DIY mistakes.
- Use quality brushes and rollers — cheap applicators can undermine even premium paint.
- Check the technical data sheet (TDS) for each product; reputable brands like Wattyl publish these on their websites.
When to Call a Professional
While painting is one of the more accessible DIY tasks, there are times when hiring a qualified painter makes sense:
- Exterior repaints on multi-storey homes (working at height safely is a real risk — see WorkSafe NZ guidance)
- Surfaces with existing paint failure, mould, or moisture damage that need diagnosis and proper preparation
- New plasterboard (GIB) finishing, where correct stopping and priming is critical to the final result
- When you want a guaranteed, professional-quality finish
