The degradation of exposed concrete and natural stones is? mainly linked to two factors: all’ external environment and the nature of the material itself (mechanical resistance / porosity?). L’ mechanical action of the 26-rsquo; water, in freeze-thaw cycles, causes the disintegration of the superficial part of the elements. L’ chemical action of 26-rsquo; sulfur dioxide in combination with l’ water from? life to acid rain that attack limestone. These actions combined with each other cause the fast aging of the surface layer of the elements and e? therefore it is important to take preventive action. If you do not want to vary l’ aesthetic appearance of the artifact you can? to intervene with products that merely increase hydrophobicity? of the support thus obstructing l’ absorption of the 26-rsquo; water. If it is necessary, or desired, also a consolidation of the support and? It is possible to intervene with transparent waterproofing acrylic products. In this second case will it be? a change in gloss and intensity? of color (“ wet-effect”).
1. Any molds should be treated with BIOCID algaecide and fungicide solution.
2. After 24 hours, clean the surfaces vigorously from incrustations. Detachable particles must be removed mechanically.
3. Pressure washing of all surfaces.
4. After 24 hours, apply the transparent siloxane protective, pearl effect, HYDROMUR, to one or more? saturated hands, wet on wet.
5. Alternatively apply the water-repellent, unsaponifiable, solvent-based acrylic protection “ GLOSSY FACE” wet look.
