Overview:

Refresh your paths, patios and other outside surfaces to look like new, removing black spot that ruins the appearance of masonry and natural stone surfaces.

Bring tired paving back to life with Flow Ultimate Black Spot Remover. This powerful, ready-to-use cleaner is designed to tackle tough black spot, algae, lichen and ingrained grime on paths, patios and other hard external surfaces.

Formulated by Flow for demanding outdoor conditions, it penetrates deep into porous stone and concrete to break down stubborn staining, helping to restore a clean, brighter finish with minimal effort. Ideal for homeowners, landscapers and maintenance teams who want fast, visible results on patios, driveways and walkways.

What the Product Does:

Flow Ultimate Black Spot Remover is an ultra-strong outdoor cleaner that:

• Targets black spot algae, lichen and organic build-up

• Lifts deep-seated dirt and weathering from stone, slabs and concrete

• Helps restore the original appearance of patios, paths and masonry

• Reduces the need for heavy scrubbing or pressure washing in many cases

Use it periodically to keep outdoor areas looking fresh, tidy and well-presented throughout the year.

How Does Flow Ultimate Black Spot Work:

• High-Strength, Ready-to-Use Formula
  No mixing or dilution required – simply pour or spray straight from the 5L container for consistent strength every time.

• Deep Penetration into Porous Surfaces
  The cleaner soaks into the surface structure, helping to loosen black spot, algae and ground-in grime that ordinary cleaners often leave behind.

• Fast-Acting Performance
  Starts working as soon as it’s applied. In many cases, noticeable improvement is seen after a single treatment, with further gains on repeat applications for heavily stained areas.

• Low-Effort Cleaning
  Apply, leave to work, then rinse if desired. Agitation with a stiff brush can be used on the worst patches, but is not always necessary.

• Multi-Surface Use
  Suitable for most patios, paths, driveways, concrete, stone slabs and other hard external surfaces. Always test first in a small, inconspicuous area.

How to Use:

• Preparation:

  • Ensure the surface is dry and free from loose debris such as leaves and soil.

  • Protect nearby plants, lawns, ponds and decorative metals where possible.

• Application:

  • Using a garden sprayer or watering can, apply Flow Ultimate Black Spot Remover liberally to the affected area.

  • Make sure the surface is thoroughly wetted; do not dilute.

• Activation Time:

  • Leave in contact for a minimum of 2 hours.

  • Do not allow the product to dry out during this time – lightly re-wet if necessary.

• Rinsing:

  • Rinsing is optional but recommended for best results.

  • Wash down with clean water using a hose or low-pressure washer to remove loosened contamination.

• Severe or Old Staining:

  • For stubborn black spots, repeat the application and allow extra dwell time before rinsing.

  • A stiff outdoor brush can be used to agitate very persistent areas.

• Precautions:

  • Avoid applying in rainy or very wet conditions, as this will dilute and reduce performance.

  • Do not decant into external containers and leave overnight.

  • Prevent runoff into drains, ponds or watercourses.

  • Keep away from children, pets and unprotected plants until the area is fully rinsed or dry.

Designed For the following users:

• Homeowners:
  Ideal for keeping patios, garden paths, driveways and terrace areas looking clean and inviting with minimal effort.

• Gardeners & Landscapers:
  Perfect for refreshing paving and hard landscaping before handover, photography or property sale.

• Commercial & Lettings:
  Suitable for forecourts, entrance paths, outdoor seating areas and communal spaces where a smart, well-maintained appearance is essential.

Additional Information:

• All-Season Use:
  Can be used at different times of year whenever staining becomes visible – avoid extremes of temperature or very wet weather.

• Reduces Scrubbing:
  Strong chemical action means less manual labour, especially when used regularly to prevent heavy build-up.

• Multi-Surface Performance:
  Effective on many concrete, stone and slabbed surfaces commonly used in patios and driveways. Always test first, particularly on coloured or delicate finishes.

• Test Patch:
  As with all Treatments, always treat a small, inconspicuous area first to confirm compatibility and finish before treating the full area.

FAQs:

• • Do I need to dilute Flow Ultimate Black Spot Remover?
  No, it is a ready-to-use formula. Apply directly from the container without dilution.

• • Can I use this on all types of stone and paving?
  It is suitable for most concrete, stone and paving slabs, but always test on a small area first, especially on decorative or coloured surfaces.

• • Is scrubbing required?
  Often, no. The product is designed to work chemically, but a stiff brush can help on particularly stubborn or long-standing black spot.

• • Can I use it near plants and lawns?
  Take care to protect surrounding planting and avoid runoff into beds or lawns. Rinse treated areas thoroughly and keep pets and children away until dry.

• • Will one application remove all black spots?
  Light to moderate staining may improve after one treatment, while heavy or older black spots may need repeat applications for best results.

• • Can it be used with a pressure washer?
  Flow Ultimate is applied first and left to work; you can then use a hose or pressure washer on a suitable setting to rinse off loosened contamination.
