After builders cleaning

Hey, do you know for removal, of efflorescence on masonry surfaces generally should not use chemical cleaners or hydrochloric acid. Chemical cleaners are less responsive to the mostly sulphate efflorescence, but may cause additional contamination and irreversible discoloration on the masonry surface.After builders cleaning London. Additional cleaning is only required if the act natural washing effect of rain can not. For cleaning such efflorescence it will do just fine if the land in question or be brushed dry in combination with a little water. For stubborn efflorescence of low water, the use of warm water has proven effective 80C as special. Soluble components of the mortar, such as calcium hydroxide (Ca (OH) 2), and washed on the facade, then whitish running tracks formed on the walls, which are designated as leachings. The emergence of the leaching is mostly due to the fact that the grout was not processed properly. The most common errors are, I will tell you: Dosing errors in the mixing of the mortar on the construction site wrong consistency of the grout Introduction of the mortar in adverse weather conditions lack of treatment of the mortar with a warm and dry atmosphere during processing inadequate water conservation measures during application and immediately after completion high water permeability of the mortar joints and voids in the joint network Calcification on masonry surfaces are more pronounced, the lower the temperature and the longer and more intense the exposure to water. The cool season is a particularly favorable conditions for the formation of calcium deposits represent the fact slowed Hydratationsablauf the mortar is a large solubility of lime, which inevitably leads to frequent and prolonged exposure to moisture Kalkauslaugungen. Since calcification with increasing duration of the carbonation (chemical reaction with atmospheric carbon dioxide) are not soluble in water, they can only be removed using awful chemical detergents. Calcium deposits on the walls can be removed usually by hydrochloric acid-based cleaners.
