RENOVATION SYSTEMS FOR EXTERNAL WALLS
Damp, salt contaminated masonry presents special challenges for renovation and maintenance.This is because dampness and salts are constantly active. They destroy masonry and coatings.
If a standard render is applied, the wall surface will quickly look mottled and unappealing. The reason for this is the unfavourable evaporation range of normal render. In normal renders, evaporation takes place at the level of the render surface, which leads to unsightly efflorescence and spalling of paint and render.
