Cork spray is an innovative coloured finish, formulated with water-based resins and cork.  Cork spray has excellent features of thermal insulation, sound absorption, breathability, water repellency and elasticity.  It is usable as a coloured finish for facades and thermal plaster. 


It has excellent adhesion capability to any kind of substrate and for this reason, it can be used in many situations such as wood, metal, plasters, synthetic materials, cementitious substrates, both inside and outside.  Cork spray contributes to the thermal and acoustic insulation of the walls to which it is applied, and it protects the structure from the absorption of wind driven rain. 


Its breathability makes breathable walls, thus contributing to the internal living comfort.  The high elasticity of the material allows the structure, finished with Cork Render cork spray, to avoid cracks and lesions.  Cork spray is available in a wide range of colours and it can be tinted using water based colours to obtain customised colours.  Cork spray is easy and simple to apply by trowel or traditional hopper gun.

What is Spray Cork 

Cork Spray: Is cork mixed with water bases acrylic resin that when applied to your home it acts as a thermal break making your home more energy efficient.   

Cork Spray is basically a wrap for the exterior of your home. 80% of cork spray is cork making the product eco-friendly.  It can be applied to the exterior of the home or the interior.   It is breathable, waterproof, thermic, sound deadening layer. The water base acrylic resin in the product repels UV ray, which reduces the fade rate.  It has a fade rate of 1% per year compared to paints and stuccos which is 6-10% per year.  Cork Spray applied to walkways makes it great anti-slip, it does require a clear coat to protect it from the foot traffic and shovels.
