Major manufacturers and suppliers all agree that annual building washing is essential if you want to protect the exterior surface of your building from the elements. In fact building washing needs to be an integral part of your regular maintenance program.
Building washing Auckland… methods for a great result
Generally we prefer not to use high pressure cleaning as it can damage sensitive surfaces. A recent study from Auckland University showed that a single use of a water blaster on a house does the equivalent of 14 years of normal weathering.
Sometimes high pressure water can force its way into your building causing electrical faults.
Because of this, for house or building washing we generally prefer use a soft brush and eco friendly chemicals or just deionized water. Stubborn stains will be taken out with a detergent or special acid wash. We are always careful not to damage paint. Our products are high quality and biodegradable. Once the exterior dirt and pollution is broken down, the residual chemical is removed with a soft water wash.
Using mould retardants
Some very good products are available that will keep algae off surfaces for a extended time. The problem with them is it usually takes several months for any noticeable change to occur. Our product offers the best of both worlds. It will not only keep algae off for months, but it acts almost instantly. The cleaning of the walls in the photo above for example took less than five minutes.
In addition, our product is eco friendly. When exposed to light and heat it turns into harmless salt water!
