Cladding Restoration

In construction sector terms Cladding is the application of one material over another to provide a skin or layer. This skin provides a degree of thermal insulation, operates as a control element for noise and provides excellent weather resistance. Cladded substrates are comprised of a variety of materials, predominately however in the UK we see their construction being of either metal, brick, vinyl or composites.

Property owners often invest heavily in Cladding , not only for the reasons noted above but because few decorative substrates can provide a recognisable corporate image in the way that a substantial cladded building can. Its an expensive commodity that is by its very nature exposed to the elements and over time it will benefit from regular maintenance.   

Our clients often engage us to restore and renovate cladded surfaces using decorative solutions. Modern coatings are specifically designed and manufactured to offer economical and effective solutions to refurbish and protect cladded surfaces. Our preferred product is described by the manufacturer, as follows: "Crown’s Trade Fast Drying Cladding Finish has been specifically developed to adhere to pre-coated and weathered metal cladding and other external features that have become dull or discoloured over time. The water-based, single pack coating breathes new life into exteriors – transforming metal cladded surfaces with an easy to achieve refurbishment process that offers outstanding protection against the elements."

Case Study - Ikea, Nottingham

Whilst undergoing a major extension & transformation Johns of Nottingham were asked to renovate the existing cladding and restore the Ikea striking blue colour, thus saving the cost and logistical issues in replacing.

The project needed to achieve a BREEAM rating of very good to outstanding. Various products were suggested along with samples being submitted to Ikea’s technical department in Sweden.

PPG were asked to specify a water-based product that would meet the criteria, so a site meeting was arranged with the PPG representative (Ashley Wilson), Client and Johns. After several meetings and further site visits to agree the required sheen levels, the proposed system was AquaCover 80 Primer and AquaCover 45 topcoat.

Once the specification had been agreed a Contracts Manager was appointed to oversee the project and ensure all works were carried out to the required standard. Most of the works were undertaken using mechanical access and whilst the store remained open to the public so ensuring the works were planned, monitored and carried out safely was paramount. Each morning before works started a meeting was held to plan and agreed the working areas and any identify potential risks. All operatives on site held trade specific CSCS cards with the sprayer having over 30 years’ experience.

Prior to the cladding being coated it was degreased and power wash rinsed with fresh water. All three coats were airless spray applied using an ultra-fine tip with care being taken to the preparation of the surface and masking of surrounding areas. Between each coat the substrate was inspected, wet film thickness tested and then signed off as acceptable to proceed with subsequent coats.

The result is a bold uniform finish in the iconic Ikea Blue without the issues associated with re-cladding.

The project was very demanding due to the colour matching, production specification, planning and time of year undertaken but collaborative working from all involved resulted in the successful completion to the expected high standard

Case Study - Poundstretcher @ Alfreton

Poundstretcher have been a regular client for Johns of Nottingham. Primarily we were asked to carry out minor repairs to the failing roof sheeting and overcoat with a 'Fit for Purpose' product to prevent any future rainwater leaking into the store.

This involved grinding back corroded cladding to a firm and bright edge and applying the Giromax System ensuring no future breakdown of the cladding. Once these works were completed it highlighted the need to enhance the overall visual appearance of the store. Following a deep clean of the cladding Approx. 1600m² was redecorated using Johnstones Steel & Cladding Coating system.

These works were applied by brush and roller due to the close proximity of the car park and to allow the store to continue trading with minimum disruption.
