Moss and algae are common on tarmac, driveways and patios in Ireland, particularly on damp or shaded surfaces. Regular cleaning and early treatment can help keep exterior areas cleaner and easier to maintain.
How to remove moss from tarmac
Start by sweeping away loose leaves, dirt and debris with a stiff outdoor brush. Heavy surface growth can be loosened carefully before applying a suitable moss and algae treatment. Avoid excessive pressure on older or worn tarmac, as aggressive pressure washing can damage the surface.
Using a moss and algae treatment
For established organic growth, a dedicated exterior treatment can be useful. Drive Clear Moss Killer & Algae Remover is a concentrated, water-based treatment suitable for tarmac, driveways, patios, paving, paths, brickwork, tiled roofs, timber walkways, wooden fences, tennis courts, sports surfaces and glasshouses.
Drive Clear is diluted at 1 part product to 5 parts water. Apply the diluted solution evenly to the affected hard surface in suitable dry conditions using a sprayer, watering can or brush, following the product label and safety information.
Can you use moss killer on a tarmac driveway?
Yes, provided the product is suitable for the surface and is used according to its instructions. Tarmac can be damaged by overly aggressive mechanical cleaning, so using an appropriate treatment and controlled cleaning method can be preferable to repeatedly blasting the surface at high pressure.
How to reduce moss returning
Moss thrives where surfaces remain damp and shaded. Keep driveways and paths clear of leaves and organic debris, maintain drainage where possible, and deal with new green growth before it becomes heavily established. Areas under trees, beside walls and on north-facing surfaces may need more regular attention.
Moss removal for patios, paving and paths
The same general approach can be used on many exterior hard surfaces: remove loose debris, apply a treatment that is suitable for the surface, allow it to work as directed and remove the inactive growth. Always check the product instructions before treating a new surface.
Drive Clear sizes
Drive Clear is available from Emerald Hygiene Stores in 5 litre, 10 litre and 20 litre sizes, with delivery available across Ireland.
