Repainting a facade

With time and bad weather, the painted facades do not deteriorate: traces of water flow dirty it, the paint is peeling in places and the coating can crack, crack or even peel off. This is particularly the case with the right of an external staircase, as here. It is necessary to wash, to decase, to brush the old paint and to repair the cracks or fragments of masonry. Painting will only take place after complete drying of the support.

  • Metal brush and soft brush
  • Triangular scraper
  • Exterior plaster and painter's knife
