We do facade cleaning, common houses as well as historical or listed buildings, from dust, dirt, paints and graffiti. According underlay material and type of contamination we pick up one of following technologies :
Mechanical cleaning :
Rotary jetting - we use grinding sand different granulity with water fog. Wide range of grinding sand, from fine plastic granules to fine quartz sand, ensures frugal way of facade cleaning. According the test in site we choose certain sand and right pressure so the original facade will not be affected. In this method when using water fog underlay is not humidified, so water dissolvable salt is not activated or moved.
High pressure facade cleaning - removing old paints and dirt with machine that uses rotary jetting located in rectangle exhaust part operated with water. This equipment works nearly without any pollution and saves enviroment. We use this system mainly for facade cleaning, cleaning floors made from natural materials (except wood) and for graffiti removing.
Chemical cleaning :
We lay on chemicals with certain cocentration on attacked surface that is afterwards peeled with colour so-called "stippling". It is used for graffiti on smaller areas. We can use cleaning gel on denticulated surface. The surface is washed with hot water (under 60 C) or water with high pressure.
Local chemical cleaning - with cleaning paste. It is very gentle for mineral basis (total removing of sulphate eschar etc.). Cleaning paste is specially developed for listed structures and is accepted by care of historical monuments.
Local brick piecing
- bricks completion of restoring mortar in requisite colour and hue
- mortar completion at areas where missing
Full-area water-repellent protection fair-face wall with easily spread cream silane - based.
Properties of water-repellent preparation-deep impregnation and long lasting effect.
Important properties :
- excellent ability of penetration
- optimal immunity against alkalis
- sinking absorbability
- high protection against freeze and thawing salt
- good tenacity
- creme consistence so no waste when application
- rainfall immunity
- high diffusive permeability
We recommend the facade cleaning before reconstruction.
