? Think Twice Before You Brush Paint Aluminium Windows

You’re staring at your old, faded aluminium window frame. The paint is dull, maybe even chipping. You’ve bought a brush, a can of paint, and you’re ready to give it a quick facelift.

Hold up.

Brush painting your aluminium window might seem like an easy DIY fix, but it often leads to disappointing results — from uneven strokes to fast peeling.

Before you waste your weekend and your energy, here’s why spray painting is the smarter and more professional solution.


? Why Brush Painting Aluminium Windows Doesn’t Work Well

Aluminium has a sleek, non-porous surface. While it’s great for durability, it’s terrible for brush paint to stick on evenly.

Here’s what typically goes wrong with brush painting:

  • Visible brush strokes
  • Peeling after a few months
  • Uneven texture
  • Dust or hair trapped in paint
  • Clumsy corners and edges

You might end up needing to repaint it again — wasting time and money. Not ideal, especially in humid climates like Singapore, where poor paint jobs degrade even faster.


? The Spray Paint Advantage for Aluminium Windows

Spray painting solves all of these issues in one clean swoosh.

? Smooth, Even Finish

Spray paint delivers a professional-grade finish with no brush marks, giving your windows that factory-fresh look.

? Stronger Adhesion

With proper prep, the spray paint adheres better to aluminium — especially when primers and topcoats are used.

? Faster Application

While prepping takes time, spraying covers more surface in less time than brushing.

? Long-Term Durability

Spray-painted aluminium stands up to Singapore’s heat, humidity, and rain better than a DIY brush coat.


? How 9reno Handles Aluminium Window Spray Painting (Step-by-Step)

When you engage 9reno, our trained technicians follow a detailed process to ensure perfection:

1. Site Preparation & Masking

We carefully mask off glass, walls, and surrounding areas to protect your space.

2. Degreasing & Sanding

We thoroughly clean the aluminium, removing oils, dirt, or previous paint layers for better adhesion.

3. Priming

A high-bond primer is applied to ensure long-lasting results.

4. Spray Painting

We use high-pressure sprayers to coat the surface evenly with professional-grade paint.

5. Final Finishing & Inspection

We ensure a flawless coat with no drips, bubbles, or marks before wrapping up.

? Fun Fact: We even match custom colours to suit your window frames and interior themes!


? Ideal Situations for Aluminium Window Spray Painting in Singapore

  • HDB flat upgrades
  • Condo window restoration
  • Landed property window refresh
  • Reinstatement work
  • Home staging before resale

Instead of replacing your entire frame — which costs a bomb — spray painting offers a budget-friendly makeover with premium appeal.


? Don’t Try it — Here’s Why

Yes, you can buy a spray can from a hardware store. But trust us, aerosol DIY cans don’t match professional tools and quality of paint

You’ll run into:

  • Overspray
  • Drips
  • Patchy coverage
  • Toxic fumes in small rooms
  • No long-term durability

Hiring 9reno ensures you get clean work, safety, and lasting beauty.
