Put a stop to black spots with
The Preventer

  • For use on both artificial and natural stone
  • Targets the black lichen spores, killing them before they can germinate, avoiding the use of harmful and impractical pesticides
  • Also kills green and red algae that grows on garden paths, patios and other decorative stonework
  • Can be used with a simple pneumatic garden type sprayer
  • Removes the needs for power washing
  • Offers complete protection when used annually

The method

1 – Using a pneumatic garden sprayer, add one part Patio Black Spot Preventer to 3 parts water (1:3).

2 – Mix Well and Use at a rate NOT EXCEEDING 5 square metres per litre (5m x 10m) area.

3 – Apply a flood coat working in sweeping strokes across the stonework. A second pass should be made at right angles to the first to ensure complete coverage.

4 – Allow to dry - DO NOT WASH OFF.

5 – Green algae will disappear within days.

6 – For application to NEW unaffected stone, the first application should be used undiluted.

Use annually for complete protection - where any green algae appears during the year, around down pipes and drains, treat locally. You do not need to retreat the whole area.

NB. DO NOT APPLY PATIO BLACK SPOT PREVENTER WHEN THE THREAT OF RAIN OR FROST IS IMMINENT
