In this video (click below) Ben demonstrates how to treat pebble dash ("dry dash") render with Benz Bio Cleanze. This is our usual method and product for treating dry dash/pebble dash render.
Bear in mind that the stains, especially red algae may take a few days to fully fade. This effect will happen more so at cooler times of the year and when the days are shorter.
The render will become progressively cleaner over the coming year because the natural cleaning effect of a Bio Cleanze treatment continues to deep clean over time. And it adds residual protection against re-colonisation.
Yes, but the first question to ask your customer is, “Why would you want to paint the pebble dash?”
The reason to ask is because pebble dash can easily be restored to near new condition with Benz biocidal treatments. And of course, once painted it will need to be re-painted on a regular basis, a process that can easily be put aside. We’ve seen many cases of paint peeling on poorly maintained painted render.
To give your customer the fastest results (if they are about to move home, for example) spray the whole elevation with Lightning Cleanze at 5:1.
Allow it to activate for 30-60 mins before lightly rinsing with garden hose pressure and/or a very wide angle fan nozzle on a pressure washer with the pressure turned down.
After rinsing, give the render some time to dry out. It does not need to be fully dry but should not be saturated. Then gently brush in a second application at 4:1, allowing time for activation before rinsing. You should see some very good results using this method.
Quick tip: Bear in mind that pebble/dry dash render can be quite delicate and a gentle approach to treatment is essential. Aggressive brushing and/or high-pressure power washing is strongly contra-indicated.
Dry pebble dash is delicate and can be challenging to clean when the colonisation is particularly severe and it has been poorly maintained for several years.
In this situation the repeated rinsing and brushing required to clean highly colonised pebble dash with Lightning Cleanze alone could dislodge some pebbles from the render.
A Bio Cleanze treatment is a highly effective way of removing organic staining. But by itself it may not give the best results on dry pebble dash that's been very highly colonised. It could take up to a year to show acceptable results and even then some deep black algae stains may remain.
The process we've found to be highly effectively for cleaning dry pebble dash:

After pressure washing (power, jet) algae spores rapidly recolonise, and properties return to square one in a very short time. So what's the alternative?

It's a free resource for people wanting to learn about the soft washing industry, to expand an existing business, or build a new business.
Soft washing reduces, or even eliminates, the need to use high-pressure washing.
Instead, once the build up of algae, lichen, fungus and mould – the root causes of properties looking "dirty" – has been treated, the natural "self-cleansing" of sun, rain and wind removes the surface residue through time.
By educating the cleaning trade and public about soft washing we are helping develop an industry that offers sustainable treatments to clean and maintain exterior hard surfaces.
