Project – Soft Wash K Render & Rend Cleaning

What did the client need?

APT were one of many companies invited to survey and quote for cleaning the K render on the building in Portishead near Bristol just off the Severn Estuary, South West England. The associated approach to the cleaning and the quote needed to be passed and agreed by the tenant’s association. APT won the contract and commenced the soft wash K rend cleaning project.

We discussed the various options of cleaning and the treatment needed to kill the algae and moss growth on the k render. One of the main factors for this cleaning project was the Health and Safety aspects. Careful management of pedestrians, tenants and our workforce needed to be considered as the building was near a main road and a river. Tenants accessed the building regularly therefore, a thorough pedestrian management system needed to be adopted.

The task of cleaning the k render would involve working at high levels with rope access and heavy plant equipment including powered high-level cherry pickers. It was important to ensure that the method used was safe for cleaning and treating of the algae covered render and that it provided a long-term, cost-effective results.

The K Rendered Mirage Building in Bristol

The Mirage project is a nine-story development of 55 apartments at the head of Portishead Marina. Below the apartments are two commercial premises (restaurants) and the car park below. Constructed of reinforced concrete and rendered with a through colour render system. It truly is a beautiful building in a fantastic location in Bristol. 

The Challenges with the Soft Wash K Rend Cleaning at Portishead Bristol

The timber pedestrian walkway facing over the harbour water could not bear any significant weight so needed to be accessed by ropes. The building also had balconies which also needed cleaning via rope access.

Therefore, we provided our specialist rope access teams and lift access to reach and soft wash the higher levels of the building.

The safety of the public and tenants was paramount, care was taken in and around the site with the two very busy restaurants and shops to the ground floor.

It was apparent at the start of the job that there were loose pavers, we needed to board and protect those in to avoid further damage and costs.

What Solutions Did APT Provide To Clean The K Render at Bristol?

  • To spray and apply algaecide solution to the k render every three years, this would help maintain the surface appearance and prevent re-growth of algae and moss.
  • To make minor repairs to some decorative timber cladding to complete the building renovation.
  • Make arrangements to re-set existing loose paving slabs and clear drainage.


APT’s Solution For Soft Wash K Render Cleaning

APT hired in the specialised lift access equipment and provided our high-level specialist rope access team.  We treated all the k rendered surfaces with APT’s Algae Free Render Cleaning Solution and Activator and used a soft wash cleaning method to start the cleaning.

We used our hot box super-heated low-pressure steam cleaners to clean the k render, this ensured the k rend was clean and free of algae spores thus avoiding any damage to the render – damage is often caused if high pressure jet washing methods are used by inexperience commercial cleaners. Soft washing combined with steam cleaning is a safe and effective way to clean k render without causing damage.

The Result Of Cleaning K Rend at Bristol

Long working hours and the dedication of the whole APT team ensured that the building was transformed back to its original condition, thus enhancing its value from both an economical and ascetical aspect. We delivered the project to very high standard as required by the client and tenant alike, who was delighted with the outcome.

Client Testimonial

“We recently instructed APT-ICC to carry out high-level render cleaning works, to treat and clean off severe algae staining from the exterior of the Mirage Building in Bristol.

The building size and restrictive access was very problematic, and we found it difficult to source a contractor with the capabilities to carry out the work and coordinate safe access for the public and the residents. APT provided a very detailed survey and full H&S plan to manage the project.

The works were carried out as prescribed and to our complete satisfaction, all at the Mirage are delighted with the result. Thank you to all at APT for giving us a new look Mirage!”
