Although vinegar and green soap are home remedies that can slightly reduce stains, we advise against using them because they can damage the structure of tiles and grout. It is better to use an eco-friendly cleaner such as Osmo Terrasreiniger.

How do I get green algae off my patio?

Start by removing dirt, apply a solution of Osmo Terrasreiniger, let it work, scrub thoroughly, and rinse with water.

Does Osmo Terrasreiniger also work on my patio tiles?

No, Osmo Terrasreiniger is only intended for wood, such as wooden decks, decking, fences and garden furniture. We therefore do not recommend an Osmo product for patio tiles. We also advise against a pressure washer, because it makes the tiles more porous, which gives algae and dirt more chance to take hold.

Preparation

Sweep the patio clean and remove dirt and leaves. Pay attention to damp spots, as green algae usually forms there fastest. Also ensure good drainage to prevent standing water.

Mix the Osmo Terrasreiniger with water in a bucket. Use the correct dosage based on the amount of buildup:

Light green buildup: Mix 1 part cleaner to 25 parts water (1:25).
Stubborn green buildup: Use a 1:1 ratio for maximum power.

Pouring Osmo Terrasreiniger into a bucket

Apply the cleaner

Apply the mixture to the patio with a patio brush. Ensure the product is evenly distributed and let it sit for 10-15 minutes without drying out.

Scrub thoroughly

Use a stiff brush and scrub the surface vigorously to loosen the green deposits, algae, and moss. For stubborn spots, you can repeat the treatment.

Rinse with water

Rinse the patio thoroughly with lukewarm water, for example with a garden hose. Avoid using a pressure washer, as this can damage the structure of the wood.

Check the patio for any remaining residue. If necessary, you can repeat the treatment to completely remove stubborn spots.

Prevent green deposits

After removing green deposits, it is important to protect your terrace against future deposits, dirt, moisture, and sunlight. Osmo Terras-Olie provides a durable protective layer that prepares your terrace or decking for all weather conditions. Based on natural oils and waxes, this product penetrates deep into the wood and protects the surface against water and dirt for a long time. Furthermore, it reduces the risk of discoloration caused by UV radiation.

Osmo Terras-Olie is suitable for various wood types, such as Afrormosia, Bankirai, Douglas fir, spruce, teak, and larch. With the right treatment, your terrace will not only continue to look beautiful but will also last longer.

Color examples

Osmo Terras-Olie is available in 10 colors, inspired by various wood types such as Teak, Bankirai, and Larch. This allows you to give your terrace the desired look, from natural to modern. Oils with color pigment offer better protection against UV radiation and graying than the colorless variant 007.

Unsure about the color? With Osmo color samples, you can easily test which shade suits your terrace best. Whether you choose a warm, tropical shade or a sleek, modern look, Osmo Terras-Olie preserves the natural wood grain and protects against the elements.
