A fresh interior paint job can instantly transform a home making it feel brighter, cleaner, and more modern. But without the right approach, that transformation can quickly turn into frustration. Poor planning, wrong materials, or skipping essential steps often leads to peeling, uneven finishes, or even expensive repairs down the line.
Here’s a closer look at five common interior painting mistakes that can end up costing more in the long run and how to avoid them for a flawless, long-lasting result.
1. Skipping Surface Preparation
One of the most overlooked steps in painting is proper surface prep. Walls may look clean, but hidden dust, grease, or small cracks can interfere with how paint adheres to the surface. Without preparation, even premium paints won’t last.
What to Do:
- Clean walls thoroughly using a mild detergent or sugar soap.
- Fill holes and cracks using putty or filler.
- Sand rough areas and ensure the surface is smooth.
- Apply primer where necessary especially on repaired patches or new drywall.
At Re Decorators, thorough preparation is always included in every interior painting service. Skipping this step leads to early peeling, uneven coverage, and a finish that doesn’t hold up over time.
2. Using the Wrong Paint Finish
Each room in a home has different conditions some are humid, others are high-traffic, and a few need extra washability. Using the wrong paint finish can result in fast wear, difficult cleaning, or an unappealing look.
Quick Finish Guide:
- Flat or matte: Great for low-traffic areas and ceilings.
- Eggshell or satin: Ideal for living rooms and bedrooms.
- Semi-gloss or gloss: Best for bathrooms, kitchens, trims, and high-moisture areas.
Choosing the right finish helps preserve the look of your room and saves money on repainting, which is why our services include expert guidance tailored to each project.
3. Not Testing Paint Colors First

Paint colours can look dramatically different on the wall compared to a swatch or digital preview. Lighting, room size, and surrounding furniture all affect how a colour appears once applied.
Smart Tip:
Apply a test patch on the wall and observe the color at different times of the day morning light, evening shadows, and artificial lighting can all reveal different tones.
Avoiding this step is one of the most common reasons homeowners repaint sooner than expected. Re Decorators includes free color consultations to ensure the final result meets both expectations and the home’s design.
4. Using Low-Quality Paint or Cheap Tools
It might seem economical to choose low-cost paint or rollers, but in most cases, it leads to streaks, uneven coats, and fast fading. Poor-quality brushes and rollers also shed bristles or leave bubbles behind.
Why Quality Matters:
- Better paints offer stronger coverage and richer colour.
- High-quality tools provide smooth application and better control.
- The finish lasts longer and is easier to maintain.
Re Decorators uses only trusted brands like Resene, Dulux, and Wattyl to deliver professional, lasting results. Learn more about our terms and conditions, warranty and process on our About Us page.
5. Skipping the Second Coat
A single coat may seem “good enough” initially, but it often results in patchy areas and reduced durability. Over time, the paint may fade unevenly or fail to protect the wall surface.
Why a Second Coat Matters:
- Enhances colour depth and consistency.
- Strengthens the paint layer for longer durability.
- Covers up underlying surface flaws more effectively.
For every interior job, Re Decorators applies at least two coats as part of a professional-standard finish ensuring the final result looks seamless and lasts for years to come.
Don’t Let These Mistakes Cost More Later
Interior painting may seem straightforward, but the difference between a quick job and a high-quality finish often lies in the details. From surface prep to final touch-ups, skipping key steps results in premature peeling, uneven surfaces, and additional costs for repairs or repainting.
