Cladding spraying in Sunderland
Coastal weather is hard on clad buildings, and Sunderland gets more of it than most. Salt-laden air accelerates corrosion at every cut edge and scratch, and North Sea wind and rain take the life out of factory finishes years earlier than they would inland. Cladding spraying in Sunderland is therefore as much about protection as appearance: the right system, applied to properly prepared panels, puts a fresh barrier between the steel and the salt while bringing the colour back.
Because exposure varies so much from one site to the next, we do not specify anything until the building has been surveyed and the existing coating tested. Two similar units a mile apart can need quite different levels of preparation, and the only way to know is to test.
The stock along the Wear
Tyne and Wear’s commercial belt is dominated by exactly the buildings spraying suits: large manufacturing and logistics units in profiled steel and composite panel, trade parks and retail sheds, workshops and depots, and offices with powder-coated framing, fascias and rainscreen details. On the older stock the original plastisol is often chalked flat, and the tell-tale orange of cut-edge corrosion shows along sheet ends, laps and around openings.
Newer composite-clad stock fares better, but even modern finishes lose gloss and depth quickly this close to the sea, and dented or scratched panels give salt a way in. The pattern is consistent: appearance goes first, edges go second, and the sheet itself goes last. A respray timed between the first and second of those stages is worth far more than one delayed to the third.
Survey first, system second
The survey is where a coastal job is won or lost. We test the adhesion of the existing finish elevation by elevation, map corrosion with particular attention to cut edges and fixing lines, and assess the building’s exposure so the specification matches the conditions rather than a brochure. Preparation, edge treatment, priming of bare metal and the coating build-up are all written down before a price is given, and the work on site follows that document.
On site the sequence is fixed: washing and preparation, then corrosion treatment and repairs, then primer where bare metal calls for it, then the coating system applied under controlled conditions with everything nearby masked and protected. Each stage is checked before the next begins. Teams cover the wider North East on the same basis, so buildings in Newcastle upon Tyne, Durham, Washington and South Shields get the same survey, the same testing and the same written specification.
Where coating stops being honest
Salt air eventually takes some buildings past the point of respraying, and we will tell you when yours is one of them. Perforated sheets, composite faces lifting from their cores, edge corrosion that has destroyed the sheet end and fixings that no longer hold cannot be coated back to health. Nor can a respray substitute for thermal or fire-performance upgrades where those are required. When the survey finds any of this, the report says so in plain terms, with our view on repair, partial replacement or full recladding instead. That honesty occasionally costs us a job. It is still the only way to run a coating service worth recommending.
Why survey-led matters in coastal conditions
Inland, a poorly scoped coating job fails slowly. On the coast it fails fast, because every missed cut edge and every skipped stage of preparation is attacked from day one. A survey-led contractor closes those gaps before they are painted over: the scope is grounded in tested evidence rather than assumption, the system is matched to the exposure rather than to habit, and the finished work can be checked against a written standard. For clad buildings in Sunderland and across Tyne and Wear, that discipline is not a refinement of the job. It is the job.
