Outdoor stone tiles around a pool, areas that are shaded by trees and away from sunlight, and tiles under wet pots are all susceptible to the growth of algae and mould.
If covered up and left for a long period of time, the mould and algae can soak into the stone and be difficult to remove. In some cases the stone will need high pressure cleaning with chlorine or honing to restore the look.
in addition to removing the source of the stain and sweeping regularly, here are some tips for preventing mould and algae growth:
Tip 1: Hose monthly
Hosing your outdoor stone tiles monthly, in conjunction with an anti-bacterial stone cleaner, will give them a deep clean that sweeping alone can’t achieve. It will also remove dirt trapped in grout joints and corners.
We recommend Stone Deep Clean
Tip 2: Heavy duty clean yearly
Moving pot plants and furniture and cleaning your stone tiles with a high pressure cleaner and Stone Deep Clean should remove algae, mould and some stains.
Caution: High pressure cleaning can damage aged stone and loosen grout. Professional cleaning of extremely dirty outdoor stone areas is recommended. Contact The Marble Man to safely restore your outdoor stone tiles.
In addition to keeping your tiles clean, it is important that they remain bacteria free to help prevent mould growth. In addition to regularly removing debris, sweeping and hosing, these tips will help keep your tiles hygienically clean:
Tip 1: Place mats or feet under pots plants
This will allow water from the pot to dry or drain away, rather than being trapped under the pot and soaking into the stone, which can cause algae, mould growth and staining.
Tip 2: Clean with a specialised anti-bacterial stone cleaner
It is important to use a cleaner that contains an anti-bacterial agent and won’t discolour or etch the stone.
We recommend Stone Deep Clean in addition to the Scrub A Dub white scourer for stubborn dirt and stains.
If you are unable to treat your outdoor stone tiles, The Marble man can do this for you. Our Technician will assess whether your tiles require just cleaning or if honing is also needed to remove deep stains.
After cleaning or honing a combination or detergents and chlorine will be used to sanitise the area. The purpose of this anti-bacterial treatment is to ensure that any bacteria left on the stone, in grout joints or natural holes in the stone, is eliminated.
Many outdoor areas have slip resistant, textured surfaces, which can be difficult to clean if left too long without maintenance. That is why it is important to clean your outdoor area regularly with an effective and safe stone cleaner.
We recommend Stone Deep Clean.
This is a biodegradable, non-acidic detergent, that removes in-ground dirt on outdoor stone tiles. It is effective for cleaning granite, limestone, marble, sandstone, slate and travertine, engineered stone tiles, porcelain, ceramic and terracotta tiles, cement pavers, masonry, grout and linoleum.
