ᐅ Waterproofing concrete pavers with a hydrophobic treatment

Hello,

I want to install standard gray rectangular pavers. Is it worthwhile to treat the pavers with a hydrophobic coating immediately after installation?

The goal is for the stones to resist dirt buildup and be easier to clean.
- Has anyone had long-term experience with this?
- How often does the hydrophobic treatment need to be reapplied to remain effective?

That is simply nonsense! Leave the stones as they are! After a few years, they will become dirty or unattractive. There is an attachment for the yellow pressure washer that cleans them.

Hello,

I haven’t had good experiences cleaning concrete pavers with a pressure washer. Although the pavers were initially clean, the dirt buildup actually accelerated afterwards. I wouldn’t necessarily recommend doing it again.

That's exactly what our landscaping contractor recommended for pressure washing. He said that using a root brush and scrubbing is the best method.

Applying a water-repellent coating to a horizontal surface can also have the disadvantage in winter that water on the surface freezes. This is especially true if there is a strong beading effect.

I am also planning to apply a water-repellent treatment to a vertical surface to reduce freeze-thaw damage. A water-repellent wall also has the advantage of significantly less algae and similar growth.
