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.

Alternatively, if you already have a pressure washer, take a look at the Kärcher surface cleaner. It can be finely adjusted and produces a much gentler, circular spray.

And with that, you wouldn’t damage the surface coating either?

According to my tiler, yes, you can. But it can be adjusted so gently that you could easily hold your hand underneath.
