Featured Snippet

If your aluminium window frames have been brush painted, they can often be restored with professional spray painting instead of replacing the entire window. Spray painting delivers a smooth, factory-like finish, improves durability, enhances property value, and costs significantly less than installing new aluminium windows.

Overview

Problem: Brush painted window frames often leave visible brush marks, uneven texture, peeling paint and poor aesthetics.
Cause: DIY painting, incorrect surface preparation, low-quality paint and weather exposure.
Solution: Remove loose paint, prepare the surface properly and professionally spray paint the frames.
Prevention: Use industrial-grade coatings and proper spray application instead of brushes.
Recommendation: Professional spray painting offers the best balance of appearance, durability and cost.

Tired of Looking at Brush Marks Every Day?

Many Singapore homeowners regret painting their aluminium window frames with a brush. It may have looked like a money-saving idea initially, but after a few months, the paint becomes uneven, brush strokes become obvious, and peeling starts to appear.

The good news? You don’t need to replace your windows.

Professional spray painting can restore your existing aluminium frames to a smooth, modern, factory-like finish at a fraction of the replacement cost.

Why This Problem Is Common in Singapore

Singapore’s hot sun, frequent rain and high humidity place constant stress on painted aluminium surfaces.

We frequently find window frames that were:

DIY brush painted
Painted by inexperienced contractors
Coated without proper primer
Painted over dirt, oxidation or silicone residue

These shortcuts lead to premature paint failure.

Common Problems with Brush Painted Window Frames

Visible Brush Marks

The most common complaint is an uneven finish that looks rough instead of smooth.

Symptoms

Brush lines
Paint overlap
Thick paint edges

Root Cause

Paint applied manually instead of sprayed evenly.

Peeling Paint

Poor adhesion causes paint to peel after months.

Warning Signs

Paint lifting
Bubbling
Flaking

Usually caused by poor surface preparation.

Colour Inconsistency

Brush application often leaves dark and light patches.

This becomes obvious under sunlight.

Rough Surface

Dust particles, roller fibres and brush hairs become trapped in the paint, leaving a coarse texture that cannot be corrected without proper refinishing.

Real Homeowner Experiences

“I thought brush painting would save money. Six months later it looked worse than before.”

“The painter finished quickly, but every brush stroke was visible.”

“We almost replaced all the windows until we discovered spray painting.”

“Our condo windows now look brand new after spray painting. We saved thousands.”

What 9reno Commonly Finds On Site

With over 15 years of experience across HDB flats, condominiums and landed homes in Singapore, we commonly discover:

Brush painted over existing peeling paint
Paint applied directly onto oxidised aluminium
No primer used
Incorrect household paint
Paint covering window rubber gaskets
Overspray from previous renovation works

Rather than replacing the entire window system, many frames can be professionally restored through careful preparation and spray application.

Hidden Risks of Delaying Restoration

Ignoring deteriorating paint can lead to:

Accelerated aluminium corrosion
More extensive surface preparation later
Higher restoration costs
Reduced property appeal
Lower rental attractiveness
Shorter lifespan of window frames

Early restoration is usually more economical than waiting until the coating completely fails.

Singapore-Specific Considerations

Follow HDB renovation guidelines where applicable.

Coastal properties require coatings with enhanced corrosion resistance.

UV-resistant finishes help maintain colour and gloss longer.
