The problem with mould spots

Mould, mildew, lichen, moss and algae can all grow on outdoor surfaces, causing an unsightly looking mess.

However, on a more serious level they also increase the risk of slips, falls and injury and can even cause long-term damage to the flooring.

Eating into your bottom line

For building contractors, removing these problems can be a time-consuming process. This means more time spent on site and higher labour costs.

Unfortunately, many of the products you find on the market are designed and manufactured for the domestic retail market. These products are based on biotechnology, and can take time to show results.

While these are fine for remove some mildew from an outside patio area, they don’t give busy contractors the results they need fast enough.
