In facade cleaning, the material decides the method. An insulated facade needs very different treatment from a clinker wall or a period building with stucco. SB Exclusive.S has been a master craft firm (Meisterbetrieb) for monument, facade and building cleaning since 2015. Facades are part of the trade name and of the master examination. Before every job we check material, condition and type of growth, and then decide which pressure and which product to use.
Master firm for facades
Our master qualification explicitly covers facade and monument cleaning. That matters for old render, natural stone and stucco, which do not forgive the wrong treatment.
Pressure to suit the material
We clean ETICS and soft renders with low pressure and a cleaning solution. Higher pressure is only used on robust materials such as concrete and clinker brick.
Protection after cleaning
An anti-algae follow-up treatment and, on request, a water-repellent treatment slow down new growth. Whether this makes sense depends on the existing render.
Site visit in person
A facade cannot be assessed from a photo. We visit you free of charge in Graz or the surrounding area and look at material and access.
Which facades do we clean, and how?
In short: every common facade, but not every one in the same way. Here are the main materials and the right approach.
Render and ETICS
With an external thermal insulation composite system (ETICS) only a few millimetres of render sit on the insulation. We clean with low pressure and a cleaning solution so the render is not damaged and no water gets into the insulation.
Algae, moss and fungi
Green and black growth is treated with an algae and fungus remover and rinsed off after the contact time. A follow-up treatment delays regrowth.
Clinker, concrete and natural stone
Clinker and concrete can take more pressure. With natural stone it depends on the type: limestone and marble are sensitive to acid, sandstone is soft. Here we choose products and pressure with particular care.
Water-repellent treatment
A water-repellent impregnation reduces water absorption without sealing the facade. It stays vapour-permeable. Silicone resin renders are usually water-repellent already.
Plinths, reveals and cornices
Splash water on the plinth and streaks below window sills are often the most visible spots. We clean them specifically and cover windows, doors and plants first.
Graffiti removal
We remove graffiti from render, clinker, metal and glass with specialist cleaners suited to the material. On request we then apply an anti-graffiti coating.
Why is high pressure risky on insulated facades?
An ETICS facade consists of insulation boards, a reinforcing layer and a thin top render. A hard high-pressure jet can roughen this render, force water into the insulation through hairline cracks and damage edges. That is why we clean ETICS with low pressure and a product that loosens the growth. Insulated facades also grow algae faster than solid walls. The outer surface cools down strongly at night, so dew stays longer. North and west sides and walls near trees are affected most.
With historic buildings it is about more than appearance. Old lime renders, stucco and natural stone are sensitive to acids, hard blasting media and high pressure. In Graz's old town, a UNESCO World Heritage site, the Graz Old Town Conservation Act (Grazer Altstadterhaltungsgesetz) also applies. For protected buildings, check in advance whether work needs to be agreed with the authority or the Federal Monuments Office (Bundesdenkmalamt). We usually start with a test area so you can see the result before the whole facade is cleaned.
How does facade cleaning work?
We clean facades in the frost-free season, usually between spring and autumn. Anti-algae products need a few dry hours after application.
