5 Signs Your Brick Needs Re-Coating Now

By /

Fading colour, efflorescence, water staining — these are early warning signs that your brick exterior needs attention. Catching them early saves significant repair costs down the track.

1. Fading or Uneven Colour

If your brick exterior has lost its vibrant colour or shows uneven patches, the protective coating has likely worn down. UV exposure and weather gradually break down surface coatings, leaving brick vulnerable to moisture penetration.

2. Efflorescence (White Salt Deposits)

White, chalky deposits on brick surfaces indicate moisture is moving through the masonry. This efflorescence is a clear sign that the existing coating is no longer providing adequate waterproofing.

3. Water Staining

Dark streaks or stains running down brick walls after rain mean water is penetrating the surface rather than beading off. This can lead to serious structural issues if left untreated.

4. Crumbling Mortar Joints

When mortar between bricks starts to deteriorate, it’s often because moisture has been getting in through a failed coating. Re-coating after mortar repair prevents recurrence.

5. Visible Mould or Algae Growth

Green or black growth on brick surfaces indicates persistent moisture — a sure sign your coating needs renewal. Professional re-coating creates a breathable yet waterproof barrier.
