Professional-Strength Outdoor Surface Cleaner

This commercial-grade outdoor cleaner tackles stubborn moss, algae, black spot and lichen stains that accumulate on Irish paving, stone and decking. The Stontex formula contains higher active ingredient concentrations than standard DIY products, delivering professional cleaning results for homeowners.

Irish weather creates perfect conditions for organic growth on outdoor surfaces. Persistent rain and mild temperatures allow moss and algae to establish quickly on paving, patios and decking. This cleaner addresses these common problems effectively, restoring your surfaces to their original appearance.

Fast-Acting Formula

Apply the cleaner to pre-washed surfaces and allow 10-15 minutes for the formula to work. The active ingredients penetrate organic growth, breaking down moss, algae and lichen at their root systems. After the dwell time, rinse thoroughly with water to reveal clean surfaces underneath.

The fast action saves time compared to mechanical cleaning methods. Rather than spending hours scrubbing with brushes, the chemical action does the hard work whilst you wait. This efficiency makes maintaining larger patio areas practical without dedicating entire weekends to cleaning.

Coverage and Dilution

One bottle covers approximately 10 square metres when used neat for heavily stained surfaces. Dilute 1:1 with water for lighter staining, extending coverage to 30 square metres. Assess your surface condition to determine appropriate dilution strength.

Pre-wash surfaces before applying cleaner to remove loose debris and dirt. This preparation allows the cleaner to contact organic growth directly rather than working through layers of surface grime. Better contact means more effective cleaning results.

Suitable Surfaces

The cleaner works safely on multiple outdoor surface types common in Irish gardens:

Natural Stone: Sandstone, granite, limestone and slate paving all respond well to treatment. The formula removes organic growth without damaging stone surfaces.

Concrete Products: Concrete paving slabs, cobble blocks and concrete patios clean effectively. The cleaner handles the porous nature of concrete that tends to harbour moss and algae.

Porcelain Tiles: Modern porcelain paving benefits from occasional cleaning to remove surface algae that can make tiles slippery.

Timber Decking: Composite and natural timber decking accumulates algae in Irish weather. This cleaner addresses the growth without harsh scrubbing that damages wood surfaces.

Garden Features: Small boundary walls, steps and edging stones also respond to treatment, maintaining a consistent clean appearance across your garden.

Application Considerations

Exercise caution when using this cleaner near plants and grass. The concentrated formula can damage organic material if applied directly. Dilute the product and rinse away from planting areas as much as possible. Cover delicate plants during application if working near borders.

Apply on dry days when rain isn’t forecast for at least 2-3 hours after treatment. This dwell time allows the cleaner to work effectively before rainfall dilutes it. Check weather forecasts before starting your cleaning project.

Post-Cleaning Treatment

After cleaning and allowing surfaces to dry completely, apply appropriate sealer to protect your investment. Sealing prevents rapid re-establishment of moss and algae whilst protecting the surface from staining and weathering.

Different materials require specific sealers. Natural stone needs breathable sealers that allow moisture movement. Porcelain rarely needs sealing. Timber decking benefits from protective oils or sealers suited to wood. Choose products appropriate for your specific surface type.
