Application:

  • Routine Cleaning: Dilute Fila PS87 at 1:10 with water. Spray the solution on affected areas, especially where moss or mould is present. Let it sit for 5-10 minutes.
  • Deep Cleaning: For stubborn stains, apply Fila PS87 Use a stiff-bristle brush to scrub the stone surface, paying particular attention to grout lines or joints.
  • Final Step: Rinse the surface thoroughly with water. A pressure washer on a low setting can be helpful for the effective removal of moss or mould.

Fila Deterdek (Acidic Descaler)

It is ideal for removing grime, saline efflorescence, and lime deposits that commonly occur on outdoor tiles.

Application:

  • Routine Cleaning: Dilute Fila Deterdek at 1:5. Apply with a long-handled brush, focusing on any area where moss or mould has formed.
  • Deep Cleaning: For heavily soiled areas or where deep efflorescence has occurred, use a more substantial dilution (1:3) or apply undiluted for tough spots. Scrub the tiles with a brush and rinse thoroughly with water.

Daily Maintenance:

  • Use a soft broom to sweep away dust and dirt.
  • Mop the area with Fila Cleaner Pro (diluted 1:100) for regular maintenance, using a microfiber mop to avoid scratching.

MOSS AND MOLD REMOVAL

Moss and mould thrive in shaded, moist environments and can stain natural stone or porcelain tile surfaces if not addressed promptly.

Step-by-step process to remove these contaminants:

  • Apply Cleaning Solution: Choose Fila PS87 for natural stone or Fila Deterdek for porcelain tiles. Apply the product to the affected areas and allow it to penetrate for 5-10 minutes.
  • Scrub the Surface: Use a stiff-bristle brush to agitate the moss or mould and remove any buildup.
  • Rinse Thoroughly: Rinse the surface with clean water. Using a garden hose or a pressure washer on a low setting is ideal for rinsing off the cleaning solution and any remaining debris.

For routine prevention, keep surfaces dry where possible, as moss and mould are more likely to grow in consistently wet areas.

RESEALING NATURAL STONE SURFACES

Sealing natural stone is critical to preventing further water absorption, which can lead to moss and mould growth, discolouration, and surface degradation.

  • Product: Fila Hydrorep (Waterproofing Sealer) or
  • Fila MP90 (Stain-Proofing Sealer)

Purpose: Protects natural stone from water infiltration, helping to prevent further moss and mould growth while maintaining the stone's natural appearance.

Application:

  • Clean the surface thoroughly and ensure it is dry before application.
  • Apply Fila Hydrorep or Fila MP90 evenly across the stone surface using a clean roller or microfiber cloth.
  • Let the product sit for 10-15 minutes. Wipe off any excess product with a clean cloth to avoid streaks.
  • Allow 24 hours for the sealer to cure before using the area.
