Spring is finally here, the days are getting warmer and the hunger for bratwurst is growing. How nice it would be if we could finally grill again if there wasn't just so much moss on the terrace! What to do?
How do I remove moss from concrete in an environmentally friendly way?
To remove moss from concrete, use an old household scrubber, a hard garden broom or a special joint scraper to remove the moss mechanically. Damp moss is easier to remove, so working on damp days or in the morning is recommended.
Of course there are various cleaners that remove moss and verdigris from a wide variety of surfaces and materials, but you can also try home remedies. These have some advantages over chemical cleaners because they are usually significantly cheaper and protect the environment.
Removing moss mechanically
Mechanical removal of moss is very labor-intensive and time-consuming. The moss has to be scraped or scrubbed from the concrete and laboriously scraped out of the joints. You will need an old household scrubber or a sturdy garden broom with relatively hard bristles as well as an old knife or a special joint scraper.
You can often remove a thin layer of moss or verdigris with a hard garden broom. However, an old household scrubber is usually more effective. If the moss is dry, pour water over it to make it easier to detach from the substrate. It's best to use the free water from the rain barrel. On a damp day or if the moss is wet with dew, moistening is not necessary.
Special joint scrapers make it easier to scrape out joints, alternatively an old knife is sufficient. You have to try out which tool is better for your work. The joint scrapers are shaped in such a way that they cut off any weeds that may be present relatively deeply and even remove smaller roots completely. Then it won't grow back as quickly. With a relatively inexpensive knee pillow you can avoid or reduce pain after strenuous work.
The most important things in brief:
- mechanical removal: with scrubber and water
- Clean joints: with an old knife or special joint scraper
- possibly use knee cushions
- Home remedies less harmful than chemical agents
Tip
If you want to remove the moss from the concrete slabs with a scrubber, choose a damp day or early morning when the moss is still damp from the dew. This makes it easier to scrub off.
