Moss not only grows under trees and on flower beds, but also on paving slabs and terraces when they are damp. Smooth surfaces can be removed from moss relatively easily, but exposed concrete is a little more difficult and labor-intensive.
How to remove moss from exposed concrete slabs?
Moss on exposed concrete slabs can be removed by flaming, using a high-pressure cleaner or using a joint scraper. Caution should be exercised when using flame burners to avoid causing fires. Regularly cleaning the joints prevents future moss growth.
S alt and vinegar are often mentioned as home remedies for moss. However, since they are harmful to the environment, large areas should not be treated with them. Scrubbing with hot water is very tiring unless your patio is small. Here you should use another method.
Can I just flame the moss?
Flaming is actually a pretty easy way to remove moss from concrete. It is environmentally friendly and leaves no harmful residue on the treated area. However, it is not entirely safe, as burning can easily cause other things to catch fire, such as your own feet or nearby combustible materials.
Is a high-pressure cleaner suitable for removing moss?
You can also use a high-pressure cleaner to remove moss from patio and sidewalk slabs. To make it easier for stubborn moss to come off the panels, you should spray them from a short distance away so that the pressure is particularly high. On the other hand, you can treat sensitive surfaces with a greater distance between the nozzle and the surface; you can also treat light dirt this way.
How do I clean the joints?
The joints are best cleaned with a special joint scraper or an old knife. However, you should carry out this cleaning relatively regularly, otherwise not only moss but also grass and other weeds will grow in the joints and may push the exposed concrete slabs up or apart.
Scraping is no longer enough to make your terrace or path nice and straight again. You should pick up the panels, straighten the surface and then re-lay the panels. Regularly scraping out joints is certainly a more pleasant job.
Ways to remove moss:
- Flame
- High-pressure cleaner
- Joint scraper
Tip
Never use flame burners near combustible materials, such as wood paneling.
