Spray Cork Rendering

A next-generation cork coating for new build and renovation projects, a sustainable, innovative solution for residential, commercial and industrial buildings.

The Material

What Is Spray Cork Render?

Spray cork render is a natural, high-performance coating made from granulated cork combined with water-based resins. The concentrated cork content delivers a fuller, higher-quality finish that transforms internal and external walls.

It is harvested from the bark of the cork oak tree without felling a single tree, making it one of the most sustainable coatings available, while offering enhanced thermal efficiency and a wide range of colour options.

How It Works

Our Application Process

A refined, fast-drying process that gets the job done with minimal disruption and a flawless finish.

01

Prepare

We assess and prepare the surface, ensuring it is clean, sound and ready to achieve the strongest possible adhesion.

02

Spray

The cork coating is spray-applied in even layers, bonding seamlessly to brick, concrete, plaster, metal or wood.

03

Finish

Enhanced drying times mean a fast turnaround, leaving a durable, breathable finish in your chosen colour and texture.

Modern Rendering

A New Generation of Exterior Wall Rendering

Spray cork render is a modern alternative to traditional sand-and-cement render, monocouche and pebbledash. Applied as a seamless sprayed coating, it combines the weather protection of a render with the natural insulating performance of cork, something conventional systems simply cannot offer.

Unlike rigid cement-based renders that are prone to cracking, spray cork render stays flexible throughout the seasons. It expands and contracts with your walls, resisting the hairline cracks and blown patches that plague older rendering methods on brick, block and existing render.

As a sprayed cork coating, it bonds directly to almost any substrate without the need for beading, meshing or lengthy curing times. The result is a durable, breathable and low-maintenance finish that keeps homes and commercial buildings looking their best for decades.

The Benefits

Why Choose Spray Cork Render?

From energy savings to a virtually maintenance-free finish, spray cork rendering delivers advantages that traditional coatings can’t match.

Superior Thermal Insulation

Cork’s natural cellular structure traps heat, reducing heat loss through your walls, cutting energy bills and keeping rooms warmer in winter and cooler in summer.

Waterproof, Yet Breathable

Spray cork render forms a waterproof barrier that still lets your walls breathe, allowing trapped moisture to escape and preventing damp, mould and blown plaster.

Crack & Impact Resistant

With up to 38% elongation, the coating flexes with your building’s natural movement, resisting the cracking and chipping common to cement renders.

Eco-Friendly & Sustainable

Made from natural cork harvested from the cork oak without felling a single tree, it’s one of the most sustainable, low-carbon wall coatings available.

Virtually Maintenance-Free

No repainting, no re-rendering. The finish resists algae, mould and UV fading, keeping walls looking fresh for 20 years or more with minimal upkeep.

Wide Range of Colours

Choose from an extensive palette of UV-stable colours and textures to suit any property, from period homes to contemporary new builds and commercial units.

The Comparison

Spray Cork Render vs Traditional Render

See how a modern sprayed cork coating compares to the cement-based renders it’s designed to replace.

Traditional Render

  • Rigid finish prone to cracking and blowing
  • Little to no thermal insulation value
  • Can trap moisture, leading to damp
  • Needs regular repainting and repairs
  • Long curing times and weather-dependent
  • Cement production carries a high carbon cost

Spray Cork Render

  • Flexible coating that resists cracking
  • Natural thermal and acoustic insulation
  • Waterproof yet fully breathable
  • Virtually maintenance-free for decades
  • Fast-drying with rapid application
  • Sustainable, natural and low-carbon

FAQs

Spray Cork Render Questions, Answered

What is spray cork render?

Spray cork render is a natural coating made from granulated cork and water-based resins, spray-applied to walls to create a seamless, insulating and waterproof finish that replaces traditional render.

How long does spray cork render last?

When professionally applied, spray cork render lasts 20 years or more. Its flexibility and UV resistance mean it won’t crack or fade like conventional cement renders.

Is spray cork render waterproof?

Yes. It creates a fully waterproof barrier that keeps rain out while remaining breathable, so any moisture within the wall can escape and damp is prevented.

Can it be applied over existing render or brick?

Absolutely. Spray cork render bonds directly to brick, block, concrete, timber, metal and existing render, making it ideal for both new builds and renovation projects.

Does it help with insulation and energy bills?

Yes. Cork is a natural insulator that reduces heat loss through your walls, helping to lower energy bills and keep your home more comfortable all year round.

What colours are available?

Spray cork render comes in a wide range of UV-stable colours and textures, so you can achieve anything from a natural cork tone to a bold, modern finish.
