I’m from Germany, but over here, there are no such forums. I recently came across a potential job, but one thing irritated me. The parking lots are all paved, but not as you would think, but with gaps in between the bricks that are like 3 centimetres wide. These gaps are filled with stone chippings. Using a surface cleaner, I fear, would wash all the filling material out. This could lead to destabilization of the whole paving. How would you do it? I don’t feel like hauling tonnes worth of stone chippings in after having finished.
I don’t do a lot of pavers or flat work, so take what I say with a grain of salt.
If you don’t want to re sand or replace the stone work between the pavers. Soft wash it with a hot mix. Hopefully the SH will lighten the pavers enough to make it look a lot better.
Might take a couple of passes, and some lower pressure rinsing in between. There should be improvement.
Maybe get a quote from a landscape guy for re sanding the pavers and give the client 2 options: Low pressure SH wash (lower price), or high pressure wash with re sanding (higher price including sub contracting to the landscaper)
Im just figuring out if I’m allowed to use SH. Germany, the country of laws and rules… Pretty high chance that using SH is forbidden. Until now, I only pressure washed without chemicals. SH as a pool mix with 13% is around 1,30 Euros the litre.
What can i use as a detergent? In germany, there are no pressure washing stores etc. Things like Elemonator aren’t available. Just normal Dish soap or laundry detergent? That will be a foamy chaos.
