Algae and black spot removal at Profile Park

Removing stains caused by algae

Profile Park is an office campus in West Dublin. The campus is surrounded by beautiful trees and greenery. Nice place to work, right? Yes, of course! However, spores being carried in the wind from the shrubbery play havoc with flamed granite and cobblelock around the building. Airborne spores cling to granite, causing unsightly black spots and a build-up of algae and moss. This is not only an eyesore, but a very serious slip hazard.

PMAC were tasked with removing stains caused by algae and had to vigorously clean the granite steps and pathways, using a combination of hot wash water, steam and mild chemicals to remove the back stains. We then applied an algae remover to kill growth. This method helps slow down re-growth, although nothing can prevent it entirely.

The work took a day to complete and the results are stunning. We would recommend protecting the exteriors further with a penetrating seal. This would help to prevent the spores gripping on the granite so easily. Because of the location, the problem will reoccur, but the seal should help with maintenance. Due to the wet, damp climate in Ireland, we would recommend resealing every six months.

Breathe new life into parks and pavements

Pmac breathes new life into building facades and public areas by removing grime, growth, grease, oil and carbon deposits from stone surfaces. Our specialist stone cleaning services cover facade cleaning, walkways, bridges and pavements. We also rejuvenate modern renders such as Monocouche,Techrete and Cladding. These are very thin renders that can’t withstand any pressure cleaning and must be treated with extreme care. If you have grimy and damaged stone or render, we can clean and restore it.

There are a variety of methods used to clean facades depending on the substrate (chemicals, biocides, steam, façade gommage® system – as featured in the video below). Too many buildings are spoiled because the incorrect methods are used.
