Cleaning, hygiene measures and subsequent disinfection of surfaces are currently a sensitive topic. But how do the terms differ and what do you need to bear in mind when cleaning ceramic and sensitive natural stone surfaces? Construction chemicals manufacturer Fila provides tips for effective yet gentle cleaning.

In a press release, the construction chemicals manufacturer Fila refers to a circular from the Italian Ministry of Health dated 22.02.2020 for effective cleaning and hygiene measures. It contains instructions on how to carry out disinfection in three phases:

1. first, the surface must be cleaned of coatings – a crucial phase. This removes the superficial, visible dirt – such as dust, organic dirt, stains, etc. This provides the ideal habitat for the spread of germs and bacteria.

2) Secondly, hygiene measures should be taken to remove the germs and bacteria present on a surface.

3. finally, disinfection must be carried out with a certified disinfectant. “Disinfection” is a term that is often used as a synonym for hygiene measures, although it has a different meaning. A disinfectant removes 99.9 percent of any bacteria, fungi or viruses present. The Robert Koch Institute recommends the appropriate disinfectants for Germany.

It is crucial that the surfaces are first brought into a primarily “clean” condition before disinfection by completely removing the existing dirt. If the dirt is not thoroughly removed, it becomes a breeding ground for germs and bacteria, which multiply again shortly after disinfection. It is therefore pointless to disinfect a dirty surface.

The Italian Ministry of Health states that thorough cleaning of surfaces with water and a suitable cleaning agent is an effective and sufficient measure in homes, rooms and public offices. The Fila range of biodegradable cleaners such as the neutral cleaner Cleaner Pro and the alkaline basic cleaner PS87 Pro are suitable for this purpose. The use of 1% sodium hypochlorite is recommended for decontamination after cleaning. For surfaces that can be damaged by disinfectants containing sodium hypochlorite or 70 percent ethanol or more, neutral cleaning agents such as the Fila cleaners Cleaner Pro and Brio are suitable. Walls, doors and windows, toilets and sanitary facilities should be cleaned with particular care. Fila recommends the ready-to-use spray cleaners Brio (universal cleaner, also for sensitive surfaces) and the slightly acidic limescale remover Viabagno (not suitable for acid-sensitive natural stone) from its range. If necessary, you can then proceed with disinfection.

To remove layers of dirt from porcelain stoneware and other ceramic surfaces, Fila recommends the use of cleaners such as its PS87 Pro against organic dirt and Deterdek Pro against inorganic dirt.

Cleaning marble, other natural stone and parquet

For sensitive surfaces such as marble, natural stone, terrazzo, engineered stone, parquet, waxed flooring, etc., the construction chemicals manufacturer recommends using a cleaner with a neutral pH value that is gentle on the surfaces and leaves no residue, such as its Cleaner Pro and Brio.

Caution with disinfectants

Disinfectants based on sodium hypochlorite (bleach) or ethanol (ethyl alcohol) can discolor and irreparably damage sensitive surfaces. Therefore, before using a disinfectant, carefully check whether it is suitable for the flooring in question.

After cleaning, the flooring should be treated with a stain protection agent. It is essential that an absorbent surface is treated with a water and oil-repellent stain protector. This prevents dirt from penetrating the material.

As the population increases, so does the density stress in Swiss cities and conurbations. At the same time, outdoor recreation and sport are becoming more important. A 2014 publication on the greater Zurich area provides examples of how existing green spaces can be made more accessible. Pieter Poldervaart analyzes the results in the December issue of G+L. You can download the Freiraumnetz Zürich study here.

8.42 million people lived in Switzerland in 2017, compared to 7.08 million or 19 percent fewer twenty years ago. In the past, this annual growth of one percent and the increasing demand for living space per capita was accompanied by a partly unchecked urban sprawl. Greater Zurich is particularly affected by the rapid growth in the resident population. Three million people live in the perimeter defined as the Zurich metropolitan area, which includes not only the canton of Zurich but also numerous municipalities in neighboring cantons and even in neighboring southern Germany.

Forecasts suggest that 30,000 people per year will continue to move to Switzerland’s economic center. In addition to housing and jobs, these people also need recreational space. In 2014, the Zurich Metropolitan Area Association therefore published an outline that shows the way to a “settlement-related open space network” – as the title suggests. In addition to describing the problem, the guide aims to show how existing recreational areas can be upgraded and new ones created and how planning is possible across municipal and cantonal boundaries.

German Brick Award 2019 presented – one prize, many awards for exemplary energy projects

The results of the German Brick Award 2019 were announced on February 1: 120 submissions of exemplary energy-efficient brick projects from all over Germany made the decision difficult for the jury, chaired by Piero Bruno from the Berlin office of Bruno Fioretti Marquez. The high design quality ultimately led to a large number of awards – two main prizes, six special prizes in various categories and eight commendations.

The main prize for monolithic construction was deservedly awarded to Harris + Kurrle Architekten from Stuttgart for the municipal library in Rottenburg am Neckar. The jury praised “the sensitive positioning of the remarkable new building as a communicative and contemplative place in the fabric of the city”. It also praised the public building for its skillful, creative use of monolithic exterior wall constructions made of highly insulating bricks.

An extension

The main prize for multi-shell construction went to the remarkable extension to the Philosophy Department of the University of Münster by Peter Böhm Architekten from Cologne. “The building, modestly described as a ‘shelf wall’, cleverly incorporates the existing listed building and forms an attractive façade opposite the historic Fürstenberghaus,” said the jury. “In this case, the haptic brick becomes synonymous with sensual appeal and a cleverly reduced, ornamental appearance.”

A special prize for energy efficiency

Several special prizes were also awarded, including one for “Cost-effective, energy-efficient multi-storey residential construction”. This was won by the Ulm-based firm Braunger Wörtz Architekten with their project at Vorwerkstrasse 23/1 in Neu-Ulm. The new building for the Neu-Ulm housing association (NUWOG) comprises 31 publicly subsidized, barrier-free rental apartments in a six-storey building and is designed as a KfW Efficiency House 70. The jury: “The uncomplicated design with monolithic brick exterior walls, which are finished with a white cement scratch coat that does not require painting, guarantees this residential building a low-maintenance, long life.”
