Salt reduction in mineral building materials

In order to successfully protect heavily contaminated buildings in the long term, in addition to preventing the ingress of moisture, measures must also be taken to combat or reduce the salts that are harmful to the building. The application of desalination compresses has proven itself as a physical desalination method.  

Desalination’ refers to the significant reduction of the content of building-damaging salts in porous building materials. In addition to the application of sacrificial plasters, compress plasters or restoration plasters, the application of desalination compresses is a method that has been used for many years in the preservation of historical monuments and is tried and proven with appropriate experience.

Gentle cleaning

Dirt is usually no protection

Due to its large inner surface, a dirt layer is an excellent absorber of moisture and gaseous and particulate pollutants. These usually react underneath the crust and accelerate the destruction, even if this initially remains invisible under the crust. There are therefore the following technical and aesthetic reasons for cleaning.

  • Elimination of risk factors such as salt accumulation and delaying the drying speed
  • Preparation of the substrate for further conservation measures by restoring capillary absorbency
  • Removal of visually disturbing soiling

Quantify lead contamination

Restoring the glamour of facades soiled by industrialisation
Typical urban façade soiling that needs to be removed when cleaning natural stone surfaces is usually caused by the deposition of atmospheric suspended particles such as dust, diesel soot, tyre and brake abrasion dust, iron dust from the railway, etc. These often contain heavy metals and can react with the stone substance and destroy the original surface. They often contain heavy metals and can react with the stone substance and destroy the original surface. Another problem with many natural stones is that the dirt particles are embedded in plaster that has formed secondarily on the surface of the stone. In any case, well thought-out cleaning processes are required that reduce or even remove the dirt, release as few pollutants as possible and protect the substrate, i.e. the original substance. A challenging task for which Clean Galena is the solution. Whether and to what extent a façade is contaminated with lead can be easily checked on site with the Remmers Lead-Box.

Cleaning compress Clean Galena

Emission-free without dust and noise

In recent years, awareness of the emissions that can arise during façade cleaning has grown considerably, and rightly so. Particular attention must be paid to the question of whether heavy metals can be released into the environment in any form during cleaning. As a paste-like cleaner, Clean Galena removes urban soiling such as tar, rust, plaster, grease and metals from valuable natural stone substrates in particular, without releasing the soiling as is common practice with conventional cleaning methods such as sandblasting. Clean Galena binds and complexes impurities and pollutants in the compress itself, resulting in a complete absence of emissions and, in addition, controlled disposal of residues.

Peel-off-paste Arte Mundit

For all interior surfaces. Without dust and water.
When cleaning interior areas, the biggest challenge is avoiding dust and the water usually required for rinsing. Preparatory and construction site measures to protect the building fabric and surrounding and neighbouring construction sections often reach the limits of feasibility and cost-effectiveness. With the development of Arte Mundit, these limitations are a thing of the past. Arte Mundit is a solvent-free peel-off paste for the water-free removal of dust, soot and other contaminants from natural stone, marble, concrete, brick, plaster, plasterboard, stucco, polished wood or synthetic building materials.
