Tannin - Imprinted Concrete

How to Remove Tannin Stains from Pattern Imprinted Concrete

Tannin stains often leave brown or yellow patches on pattern imprinted concrete, making it look dirty, old, and stained. Many people mistake these marks for dirt, but tannins come from natural plant matter and are tricky to remove.

Regular cleaners usually don’t work well on tannin stains and can damage the colour or seal if used incorrectly. A specially made cleaner lifts tannin stains without harming the surface or weakening your concrete’s colour and sealant.

What Causes Tannin Stains on Imprinted Concrete?

Tannins are natural compounds in plants and wood that stain surfaces when rain or water pulls them out.

Common sources include:

• Leaves and Twigs – Fallen leaves rot and leave stains after heavy rain.
• Timber Furniture and Planters – Wood, especially untreated, can release tannins when it gets wet.
• Tree Sap and Bark Mulch – Bark and sap run off in rain and stain nearby surfaces.
• Compost and Garden Beds – Soil and mulch near concrete can wash tannins across the surface.

Tannins stick to textured concrete and sink into the surface, so basic cleaning won’t remove them easily.

How to Clean Tannin Stains from Stamped Concrete

If your concrete is sealed or coloured, always use a cleaner made for tannins to avoid damage.

Our specialist cleaner:

✅ Breaks down tannins, even on textured or rough concrete
✅ Won’t affect colour or sealers—no acids included
✅ Requires no hard scrubbing or pressure washing

Most stains go away after one treatment, but darker patches might need a second clean a few days later.

How to Stop Tannin Stains Before They Start

You can reduce tannin build-up by keeping the surface clean and protecting it from moisture and plant debris:

✅ Use a proper concrete sealer – Keeps tannins and water from soaking in
✅ Sweep often – Clear leaves and twigs before they rot
✅ Avoid direct wood contact – Put planters or furniture on risers, not directly on concrete
✅ Rinse after heavy rain – Wash the area to prevent tannins from sticking

Why You Should Avoid Acid Cleaners

Some people use vinegar or lemon juice, but acids damage stamped concrete and ruin colour or sealant.

Acidic products may:

❌ Fade the surface or make it dull
❌ Strip the colour or top coat
❌ Speed up surface wear, leading to more stains later
