Practical Guide: How to Remove Algae, Mould, Moss and Lichen from Outdoor Porcelain Tile and Ceramic Surfaces
Outdoor surfaces made of porcelain tile and ceramic can develop algae, mould, moss and lichen over time, especially in damp and shaded areas.
Therefore, this guide explains when to take action and how to clean these surfaces correctly, removing biological growth without damaging the material. You will also learn how to remove algae, mould, moss and lichen from porcelain tile safely and effectively while restoring the original appearance of outdoor surfaces.
When to Clean
- dark stains and discolouration
- surface biological deposits
- algae, moss or lichen growing in grout joints
- slippery surfaces
- loss of visual uniformity
Type of intervention: extraordinary cleaning, to be repeated only when necessary.
Where to Use It
- outdoor porcelain tile floors
- outdoor ceramic surfaces
- terraces, balconies, courtyards and walkways
STEP 1 – Stain Removal Treatment
Product: ALGANET®
To remove algae, mould, moss and lichen from porcelain tile, use ALGANET® by carefully following the instructions below.

- before drying, make sure the product does not come into contact with plants or flower beds
When used correctly, ALGANET® provides a reliable and safe solution for cleaning outdoor surfaces, especially when removing algae, mould, moss and lichen from porcelain tile without damaging the material.
Final Result

Technician’s Tip
For routine cleaning of outdoor floors, we recommend using ECOMARBEC. It cleans and degreases effectively and is safe for plants when used correctly.
After completing the extraordinary cleaning with ALGANET®, and once the surface is perfectly clean and dry, you can also apply ANTISPORCO. This protective treatment is specifically designed for porcelain tile. It reduces dirt absorption, makes routine maintenance easier and helps limit the reappearance of algae and biological films over time.
