Cladding Spraying in Shrewsbury
National Coating Specialists provide professional cladding spraying services across Shrewsbury and Shropshire, restoring and protecting commercial, industrial and agricultural buildings. Our survey-led approach ensures every project is assessed individually, with no two roofs or walls receiving the same treatment. Shrewsbury’s mix of historic market town architecture and modern industrial estates creates unique challenges – from the Victorian brickwork of the town centre to the steel-clad units on Shrewsbury Business Park. We specialise in spray-applied coatings that bond permanently to existing surfaces, eliminating the need for costly cladding replacement while delivering 10-15 years of weatherproof protection.
Shrewsbury Buildings That Need Cladding Protection
Across Shrewsbury, we regularly treat: the corrugated asbestos roofs on Battlefield Enterprise Park; rendered walls on Meole Brace retail units; steel-clad agricultural buildings around Bayston Hill; and the flat roofs of Shrewsbury College’s campus buildings. The town’s position in the Severn Valley means its commercial properties face particular weathering challenges – from driving rain off the Welsh hills to winter freeze-thaw cycles that crack older coatings. We work with distribution warehouses along the A5 corridor, food processing plants near Harlescott, and heritage buildings in the town centre where traditional materials need modern protection without altering appearances.
Why Shrewsbury Cladding Fails Over Time
Shrewsbury’s climate and pollution levels create four main failure modes we encounter: UV degradation on south-facing elevations (especially on plastics and rubbers); thermal movement cracks in older acrylic renders around window reveals; corrosion ‘tracking’ beneath poorly sealed fixings on industrial units; and biological growth (algae, lichens) in shaded areas near the River Severn. The town’s clay subsoil also causes subtle building movement that stresses rigid cladding systems. Unlike replacement, our spray coatings flex with these movements while sealing against moisture ingress – a critical advantage for Shrewsbury’s weather patterns.
What Our Cladding Spraying Work Involves
Every project begins with abrasive blasting to remove loose material and create a mechanical key, followed by detailed crack stitching with fibreglass mesh where needed. We then spray-apply a high-build elastomeric coating (typically 800-1200 microns dry film thickness) using airless equipment that reaches into panel seams and fixings. For asbestos roofs, we first stabilise with a penetrating primer before the topcoat. The final stage involves sealing all penetrations with polyurethane mastics and applying anti-carbonation coatings to exposed steel edges. Crucially, our systems maintain vapour permeability – allowing buildings like the old maltings on Frankwell to ‘breathe’ while being protected.
Our Survey-Led Process
We insist on an initial site survey because Shrewsbury’s building stock varies so dramatically. Our surveyor will: measure roof pitches and access challenges; identify underlying substrates (many ‘concrete’ roofs turn out to be asbestos once probed); test moisture content with a tramex meter; check for previous failed treatments; and assess wind loading factors – particularly important for exposed sites like the livestock market. Only then do we specify a system, always allowing for substrate variations we often uncover during the works. This prevents the ‘one product fits all’ approach that fails so many local buildings.
When We Will Tell You It’s Not The Right Answer
We regularly decline work where: the underlying structure has advanced corrosion (common in 1970s steel decking); asbestos cement sheets are delaminating internally; or existing coatings contain incompatible silicones. In these cases – often found on older industrial units around Sutton Farm – overcoating would be unethical. We’ll explain why replacement is needed, and can recommend demolition contractors if appropriate. Likewise, we won’t spray historic brickwork where breathable lime washes would be more suitable, such as parts of Shrewsbury’s old gaol buildings.
