K Render Cleaning & Algae Removal at Leisure@Cwmbran
Client: Mint Blue Ltd
The k render facade of the Leisure@Cwmbran complex had become badly stained with airborne pollutants and algae/moss growth which was unappealing to users of the centre. The client set out an enhancement programme to improve the aesthetic of the centre which included exterior cladding cleaning to remove algae from the k render, remove surface staining and treat and kill moss from all pedestrian pathways. It also included cleaning of stone and masonry to remove graffiti and effervescence staining.
The timescale provided by the client was 13 days.
There were difficult obstacles regarding constant public use in many parts of the building and day to day shoppers on the busiest thoroughfare in the town. These problems were overcome by developing a detailed and flexible approach and day to day management on behalf of the client who has now suggested a further two similar jobs in the future and a regular annual maintenance re-visit.
APT carried out a full property survey with the client management team and discussed the various options and approach to the job including the safety of public and traffic management. APT provided all the health and safety paperwork to include the use of high level cleaning works and special access platforms. A detailed project plan and schedule was developed, to reduce disruption to public and traders. We hired special lift access equipment and liaised with roads and highways departments.
APT carried out the k render cleaning after first carrying out a test area sample to agree the finish and standard. We then treated affected surfaces with APT Algae Free, our own brand of algae remover treatment. (Please click here for more information on Algae Free).
APT then cleaned and removed the stubborn algae patches using low pressure; high steam hot box systems in order not to damage the k render coating.
The soda blast cleaning team (Click here for more information) cleaned and restored the stone surfaces, to remove graffiti and effervescence staining. (Click here to view our range of graffiti removal products).
Pedestrian pathways were treated to remove and kill moss and then pressure washed to clean the concrete and tarmac surfaces.
We delivered the project to standard required by the client.
What Our Client Said
Our company act as managing agents to the owners of several large commercial and leisure/retail developments, some of which were affected by unsightly algae on exterior rendered surfaces.
We approached APT for advice and they attended promptly, surveyed the buildings, provided detailed proposals for treatment products and methods including how best to clean at high level. They acted professionally throughout, dealt with all health and safety aspects, liaised with local highway authorities where temporary pavement closures were needed and managed the projects for our clients.
The results were better than we expected and we will have no hesitation in using APT again on future projects.
