Why do I need a render cleaning service?

Modern exterior colour through render finishes such as K-rend, monocouche and many others are today favoured by architects, developers and construction companies. These renders offer a sleek low maintenance and quick to apply finish that gives the building clean lines and surfaces. The use of colour through renders eliminates the need for painting and therefore should reduce the ongoing maintenance costs for building managers.

Due to modern building standards which require higher insulation values to be installed in all new builds combined with the increased use of render, we have inadvertently provided the perfect environment for algae, fungus and lichens to flourish. Instead of increasing the maintenance period of a building, we have in fact made it more necessary to clean and maintain the building more often. With the more efficient insulation installed, there is less heat transfer from the buildings interior through the walling to the exterior surface. This combined with the porosity of render, means that the building exterior surface can take longer to dry out, thus providing the perfect environment for molds, fungus and algae to grow.

Our render cleaning team uses specialist soft washing equipment, chemicals and softwash techniques to ensure that your home or building is restored in a safe, effective and professional manner.
Red staining on walls can leave a building looking unsightly and ill cared for. Our biocide and blackwash treatments work in tandem to ensure a long lasting deep clean. Once the biocide is applied to the surface being treated, it immediately starts to kill any biological contamination present. This will remove all green algae within a day and any red staining will begone with two weeks on average. Should you require a more instant clean, we use our blackwash solution followed by a light coating of biocide.

What equipment do you use to softwash?

As the name implies, Soft Washing is a gentle way to clean contaminated exterior surfaces. It is not a replacement for pressure washing, more a complimentary technique that is used as per the requirements of the surface and often in tandem with light pressure washing.

All of our equipment and chemicals are professional grade and designed for our softwash render cleaning service.

Our equipment consists of Low Pressure, chemical resistant pumps that are driven by small and economical petrol engines. The pumps apply the chemical solution up to a maximum of 15 Bar (217 psi) of pressure, with the average mains water pressure in Ireland ranging between 1 – 5 bar you can see that our equipment is pretty gentle.

The softwash solution is applied to the render through a water fed poles system with either a brush attachment or a spray nozzle on the end, depending on the best application method for the surroundings, weather conditions and the building being cleaned. We tend to favour the brush method as it reduces wind drift of the solution.

A pressure washer is used at low pressure to give us an effective high flow rinse of 15 litres per minute. This gives a really good flush clean of all surfaces and clears all the chemical and loose detritus in the process.

Would my render benefit from regular maintenance?

Render cleaning on a regular schedule would certainly be of benefit to your home or property and help keep it in prime condition for many years. Even new builds should have planned maintenance.

Rendered walls  like any other outdoor surface are exposed to all that our damp, cool climate has to throw at them. Days of constant rain with no real drying effect can certainly take its toll

Surfaces that are contaminated with algae and lichens take longer to dry out, this allows the biological organisms to flourish and spread over the surface. This holding of water can leave many substrates susceptible to frost damage. We would recommend that most rendered surfaces are treated on an 18 – 24 months cycle as spores will have taken root since the initial clean. Even new builds would benefit from a maintenance treatment within the first 2 – 3 years, this helps prevent any colonisation and avoids the need for a more costly deep clean or the eventual need to paint.

A render deep clean or a maintenance treatment for your new build home will restore or maintain your homes Kerb Appeal.
