Internal Coating

Make your home healthier. 

Due to the climate in the UK, which is damp and humid, many houses have poor air quality and are at risk of black spot mould.

These conditions pose problems for your health, including respiratory infections, allergies, asthma, immune system issues and Long Covid related illnesses.
These issues are more prevalent in the winter months, when the temperature drops, and ventilation becomes harder – many people close windows to retain what heat there is in the house.
The lack of insulation can be a leading cause of mould growth because external walls are generally cold and attract the water vapour that is in the air, which turns to condensation when it comes into contact with the colder surface. And it is in these conditions that mould thrives.

It is important to ensure there is sufficient ventilation to allow the moist air to escape from the room before it settles on the internal surfaces, but it is equally important to insulate the property to make the walls warmer. That is why CorkSol SprayCork is the ideal solution as a Thin Internal Wall Insulation (TIWI) solution.
Thanks to the thermal properties of cork, SprayCork warms the walls sufficiently to move the dew point and stop the formation of condensation on the walls. In addition to this, the material is breathable which allows vapour to pass through the walls, which they were traditionally designed to do, which means that there is no build-up of moisture on the surface. And as SprayCork contains no chemicals, it is perfectly safe to apply internally – even if you’re in the house.

CorkSol SprayCork is the ideal solution for internal as well as external coatings.

As a natural product, cork is breathable and has great thermal properties so can be used internally to solve issues with damp and mould.

Our approved applicators use a thin layer of spray-applied natural cork, one of the world’s most incredible and sustainable natural resources. This can then be over skimmed and painted giving you the freedom to decorate over it as you please.
  • Sustainable and breathable natural product
  • Final coating is only 6-8mm thick so no need to worry about replacing fixtures and sockets etc.
  • Can be plastered over with a thin layer for a smooth finish
  • You are left with an invisible solution that mould or damp cannot form on
