Sprayed cork is genuinely different — it's flexible, vapour-open, has real insulating value, and bonds to surfaces other renders struggle with. For specific Sunderland use cases, it's outstanding.
Why Cork Spray in Sunderland?
Self-coloured — wide palette, no separate paint cycle.
Local context: Sunderland, Tyne and Wear
Large interwar and postwar estates with original cement render and pebbledash; coastal-facing properties take the brunt of North Sea weather. Salt spray and easterly gales degrade non-flexible renders quickly — modern silicone systems extend coastal lifespan dramatically. We cover the full Tyne and Wear area from SR1 outwards, including Roker, Seaburn, Fulwell, Ashbrooke, Tunstall and the wider postcodes (SR1, SR2, SR3, SR4, SR5, SR6). Most Sunderland jobs are surveyed within 48 hours — we know the streets, parking constraints around landmarks like Stadium of Light, and the typical substrates we'll find on the wall.
Benefits
- Sound-dampening characteristics on some substrates.
- Flexible — bridges hairline cracks rather than splitting at them.
- Vapour-open — safe for older solid-wall properties.
- Modest insulating value — a useful thermal bonus.
- Bonds to wood, metal and painted surfaces.
- Self-coloured, no paint cycle.
Local considerations
- Spray application means careful overspray containment in Sunderland's tighter streets.
- Cost per m² is higher than standard render — but the specialist properties justify it on the right job.
- Cork spray is a specialist system — not all renderers can apply it properly.
- It's not a full EWI substitute; if you need significant U-value uplift, go EWI.
- Substrate prep and primer are non-negotiable — skipping them is the most common failure mode.
Our process in Sunderland
- Survey — substrate assessment, suitability check, sample on the wall.
- Scaffold or tower access depending on height.
- Substrate prep — clean, repair, prime with system primer.
- Spray-apply base coats per manufacturer spec.
- Spray finish coats to required thickness in chosen colour.
- Snag, clean, scaffold down.

Frequently asked questions
Can cork spray solve damp?
Cork is vapour-open, which can help with cold-bridging condensation. It doesn't fix rising or penetrating damp on its own.
Is cork spray render worth it in Sunderland?
On the right substrate and use case — yes. Especially on flexible / movement-prone substrates, on wood or metal, or where breathability is critical.
Does cork spray insulate?
It has modest insulating value — useful, but not a substitute for EWI if you need significant heat-loss reduction.
Can you spray cork over existing render?
Over sound existing render, yes — with proper prep and primer. Over failing render, no — strip first.
What colours are available?
A wide palette — sample colours brought to survey and applied on the wall for sign-off.
How long does cork spray last?
20+ years with proper substrate prep and system application.
