As buildings get older, dirt and grime due to air pollution, car exhausts, water run-off, and dust from building equipment or nearby construction sites can build up on the exterior facade.
But when cleaning and repairing old buildings, especially when considering heritage or other historically significant buildings, special care needs to be taken to preserve the building material and its original look.

The right approach
“Since many of these heritage buildings were constructed with sandstone exteriors, a delicate process is required for cleaning – using normal high-pressure cleaning will almost surely damage the building facade,” stresses Nico van der Merwe from Ceilspray.

“It is therefore imperative to appoint professionals with the required knowledge, equipment and experience to get the job done.”

How is it done?
Ceilspray uses a high-pressure system with a whisper-wash nozzle that is easy on sandstone, but very effective in cleaning these surfaces. This system was specifically developed for the purpose of cleaning heritage building exteriors with care.

“This specialised treatment is ideal for porous surfaces, and includes the treatment of natural and synthetic stone as well as concrete and vinyl substrates,” Van der Merwe explains. “With this system, old building facades can easily and safely be cleaned and restored to their former glory.”
