Hello everyone,
In a few months, I will be installing the patio slabs and garden paths. I really like light-colored stone. From my experience, porous stones (such as sandstone) tend to develop a lot of algae and moss over the years, especially in shaded areas. New sandstone looks great when fresh, but unless you regularly use a pressure washer, it won’t stay that way for long.
Can anyone recommend types of stone that are less prone to algae growth (for example, granite or similar)? Are there light-colored stone varieties suitable for this?
P.S.: I know the stone can be sealed, but that’s too much effort for me, especially since the sealing needs to be renewed regularly.

Color: Bianco fine, homogeneous surface, thermo-sealed facade with colored natural stone aggregates and UV-resistant color pigments INTRACLEAN for a dirt-repellent surface With this “high-tech description,” they shouldn’t even get dirty.
You should be able to clean the panels with water and a brush since the dirt is only superficial.
How “bad” do they look? Any pictures?
But cleaning only in spring, right?

Especially older concrete slabs develop very fine porous channels over the years.
Some moss roots can grow into these channels.
If you scrub only the surface, the roots remain inside the fine channels and will keep growing back.
The only way to completely remove them is by thermal treatment through overheating (sterilization).

What is the best way to clean these when high-pressure washers are not an option?Last year, in the courtyard (concrete pavers), we switched from high-pressure washing to just scrubbing with a broom after pretreating with baking yeast. The water is applied from a hose with a spray nozzle, so it’s lower pressure. From my experience, high-pressure washing has a mixed effect: the strong pressure mostly just splashes back what it had pushed deeper into the pores. The alkaline reaction from the baking soda solution removes dirt more effectively than the brute force approach of a pressure washer lance.https://www.instagram.com/11antgmxde/
