Over time, moss, algae, and lichen spread across roofs, decks, facades, and pavers. That green growth does more than spoil the look: it traps moisture on the surface, makes walkways slippery, and can damage the material. The right moss remover kills the green growth and slows its return.

Why Does Moss Grow?

Moss and algae thrive on shady, damp, and porous surfaces: north-facing roofs, areas under trees, concrete, and the joints between pavers. Pressure washing removes the visible layer, but microorganisms stay in the pores and the green growth comes back quickly.

How to Choose a Moss Remover

  • Roofs and facades: a professional biocidal concentrate such as TopEfekt MOSS, which kills moss, algae, and fungi and helps prevent regrowth.
  • Decks, balconies, paving stones: moss remover is suitable for removing green growth from a variety of outdoor surfaces.
  • Pavers and preventive protection: moss and lichen remover cleans the surface and leaves a protective effect.
  • General outdoor grime: heavy-duty APC OUT for facades and outdoor surfaces.

How to Use a Moss Remover, Step by Step

  1. Pick a dry day: the product needs time to work, and rain shouldn’t wash it off right away.
  2. Remove loose moss with a brush or scraper.
  3. Dilute the concentrate according to the product data sheet and apply it with a sprayer or brush.
  4. Let it work for the time stated on the product data sheet. Dead moss darkens and loosens.
  5. Clean the surface with a brush or a low-pressure washer.

Tip: treat the surface preventively once a year so the green growth never gets a chance to build up.

Safety

  • Wear gloves and safety glasses; use fall protection when working at height.
  • Protect plants and lawns by covering them or wetting them with water before and after treatment.
  • Do not let the product enter bodies of water or drains.
  • Read the product’s safety data sheet before use.

Frequently Asked Questions

Isn’t a pressure washer enough?

Pressure washing only removes the top layer and can damage porous surfaces. Without a moss remover, moss grows back quickly.

When is the best time to remove moss?

In spring or fall, during dry, mild weather when temperatures are above freezing.
