The product
SprayCork — a next-generation sprayed cork coating.
SprayCork is a natural cork-based sprayed coating for new build and renovation projects. It delivers a sustainable, high-performance finish for homes, residential, commercial and industrial buildings — internally and externally.
The concentrated cork content delivers a premium finish that transforms internal and external walls — with strong eco-credentials, enhanced thermal efficiency and a wide range of colour options. Recommended by Kevin McCloud of Grand Designs, SprayCork is an eco-friendly, high-performance alternative to traditional render and paint systems.
Cork is harvested from the bark of the cork oak — no trees are felled, and the bark regrows naturally. As it regrows, the tree absorbs more CO₂ from the atmosphere, making cork one of the few genuinely carbon-negative raw materials in construction.
The raw material
The cork oak — a tree that gives without being taken.
The cork oak (Quercus suber) is an evergreen native to the western Mediterranean — Portugal, Spain, France, Italy and North Africa. Unlike most oaks it doesn't shed its leaves, and it grows a thick, knobbly outer bark that is the cork itself.
During harvest the tree stays standing. Skilled workers strip sections of the outer bark by hand, and the tree regenerates it naturally. A cork oak first yields cork at around 25 years old, can be stripped once every 9–12 years, and lives for up to 200 years — a single tree can be harvested more than 16 times in its lifetime.
A genuinely renewable harvest
No tree is felled to make SprayCork. Bark is peeled by hand and regrows on the living tree. Because regenerating bark requires extra carbon, a harvested cork oak stores up to five times more CO₂ than one that is never stripped — actively rewarding the harvest.
Forests rich in life
Cork oak landscapes are among the most biodiverse forests in Europe — up to 135 plant species per square kilometre — and provide habitat for endangered wildlife including the Iberian lynx, Barbary deer and Iberian imperial eagle. Buying cork keeps these forests economically viable and standing.
A barrier against desertification
Cork oak forests prevent soil erosion, increase rainfall absorption and act as a living barrier against the desertification spreading north from North Africa. Every cork project — including yours — helps maintain the case for keeping these forests intact.

The benefits
Why SprayCork
Weatherproof, B-rated fire resistance, acoustic absorption, adhesion to almost every surface, and natural resistance to cracks, damp, condensation, algae and moss — plus:
Natural & Sustainable
Made from cork bark harvested without felling trees — a fully renewable raw material that absorbs CO₂ as it regrows.
Improved Thermal Performance
High cork content makes SprayCork an outstanding thermal regulator, reducing heat loss and fuel usage.
Improved Finish Quality
Concentrated cork gives a fuller, richer, more textured finish than conventional render or paint.
Wide Colour Range
Available in 28 standard colours to suit British tastes, with bespoke tinting and colour matching for any order.
Fast Application
Enhanced drying times keep projects on schedule — most homes are completed in days, not weeks.
25-Year Product Warranty
Backed by a manufacturer-issued 25-year product warranty for long-term peace of mind.

Where it's used
Applications
SprayCork bonds to almost any sound substrate — brick, block, render, concrete, timber, metal and asbestos cement — making it suitable for a wide range of residential, commercial and industrial projects.
- External walls — render replacement, over-cladding and weatherproofing
- Internal walls — feature finishes, damp-prone rooms and cold spots
- Conservatory and flat roofs — thermal & acoustic upgrade
- Cracked, blown or failed render — flexible bridging coat
- Asbestos cement panels and garages — encapsulation
- Industrial roofs, hangars and commercial façades
How it's applied
Application process
- Step 01
Surface preparation
We clean, repair and stabilise the substrate — removing loose render, moss and contamination, and treating any defects.
- Step 02
Primer coat
A bonding primer is applied to ensure full adhesion across brick, render, concrete, timber, metal and asbestos cement.
- Step 03
Spray application
Two to three layers of SprayCork are sprayed on at a controlled thickness, building up the protective and decorative finish.
- Step 04
Cure & inspection
The coating cures within hours. We inspect every elevation, tidy the site and walk you through the finished work.
