Scraping out the grout is probably the most tedious job when cleaning sidewalks and patios. You have to get down on your knees for better or worse. How nice it would be to prevent the growth of moss in joints.
Moss doesn't stand a chance with sealed joints
There are various ways of protecting terrace surfaces or concrete slabs from moss growth. You can impregnate or seal the surfaces. However, this does not protect the joints or protects them only slightly. An effective prevention against moss in joints is a weed killer. However, this measure has to be carried out again and again and pollutes the environment.
What is the difference between sealing and impregnating?
A seal should form an impermeable film on the treated area and seal it completely. As a result, the surface shines and is particularly easy to clean. If the sealing gets into the joints, then at least less moss and weeds will grow there, narrow joints can even be completely sealed. However, concrete may become more sensitive to frost as a result of this treatment.
In contrast to sealing, impregnating agents penetrate the pores of the stone or concrete slabs but do not form an impermeable film. They are moisture permeable but repel dirt. Accordingly, they are not as effective in joints as a seal.
How do I remove moss from the joints?
Without sealing, impregnation or weed remover, sooner or later moss will grow in your joints. You should use a knee pillow so that your knees do not hurt or at least do not hurt too much after being scratched.
You can get this cushion for little money on the Internet or in garden shops, as well as special joint scrapers that make it easier for you to remove moss and weeds and also remove the roots (at least partially). Alternatively, you can of course scrape out your joints with an old knife.
The essentials in brief:
- Sealing: complete sealing of the surface
- Impregnation: penetrates pores, not an impermeable film
- apply as early as possible
- Be sure to clean the joints beforehand
- Weed killers help, but are not necessarily environmentally friendly
tips
Use weed killers as little as possible and only sparingly, so you not only protect the creatures in your garden.
