Repair cracked render, protect your walls and refresh your property with a breathable ReveCork spray cork finish. Designed for UK properties, spray cork provides a flexible, weather resistant coating that helps cover existing surface cracks, reduce future cracking and protect external walls from the elements without the disruption of full re-rendering in many cases.
A Flexible Alternative to Traditional Render Repairs
Cracked render can make a property look tired, but it can also allow moisture into the wall if left untreated. Over time, small cracks may worsen due to weather exposure, freeze-thaw damage and natural building movement.
Spray cork is a breathable, flexible coating that can be applied over suitable existing render after the correct preparation and repairs have been carried out. It creates a seamless protective finish that helps improve appearance, resist weathering and reduce the risk of recurring surface cracks.
At Spray Cork UK, we use advanced ReveCork systems because they are specifically designed for demanding environments and long term durability. ReveCork combines natural cork with elastic waterproof resins and breathable technology to create a highly flexible, weather resistant coating suitable for UK housing stock.
We supply and support approved applicators across the UK through Spray Cork UK, helping ensure cracked render repair projects follow the correct preparation methods, coverage rates and technical guidance.
Traditional masonry coatings can become brittle over time, particularly on older or exposed properties. ReveCork systems are formulated with highly elastic resins designed to cope with substrate movement and help reduce the chance of hairline cracks returning.
Breathable and moisture friendly
Spray cork is vapour permeable, allowing moisture to escape rather than becoming trapped within the wall. This makes it a strong option for older and solid wall homes where breathability is important.
Weather resistant protection
ReveCork systems are designed to withstand harsh environmental conditions including driving rain, frost, UV exposure and saline environments. Independent testing shows resistance to marine and salt mist exposure of over 2,000 hours.
How Spray Cork Helps Repair Cracked Render
Spray cork is not simply painted over cracked render. The existing surface must first be inspected to identify loose, hollow or failing areas. Any unstable render should be removed or repaired before the coating is applied.
Once the surface is prepared, spray cork is applied as a seamless layer across the wall. This helps create a clean, uniform finish while adding flexibility and weather protection to the façade.
For properties where the existing render is structurally sound but visually cracked or weathered, spray cork can be a practical alternative to full re-rendering. It can refresh the appearance of the home, help protect the wall and reduce ongoing maintenance.
ReveCork MT-1000 elastic mortar systems are specifically designed for façade renovation, sealing small and medium sized cracks, preventing micro-cracks and protecting walls against moisture and environmental exposure.
The success of any cracked render repair project depends on preparation, product quality and correct application. We help ensure every project follows the right process from inspection through to completion.
Approved applicator network
We work with trained and approved applicators across the UK who understand how spray cork should be used on cracked, weathered and ageing render surfaces.
Genuine system and documentation
We provide access to technical data sheets, testing information and certification so you can be confident you are using a genuine ReveCork system rather than a lower quality imitation product.
Suitable for UK properties
Spray cork is designed for real UK conditions, including rain, frost, wind exposure and coastal environments. Its flexibility and breathability make it well suited to British housing stock.
A cleaner alternative to full re-rendering
Where the existing render is suitable, spray cork can avoid the disruption, waste and cost of removing and replacing the entire rendered finish.
Cracked Render Repair FAQs
These answers cover the most common questions about cracked render repair with spray cork, including suitability, preparation and long term performance.
Can spray cork be used to repair cracked render?
Yes, spray cork can be used on suitable cracked render after the correct preparation has been carried out. Loose, hollow or failing render must be repaired first, but where the surface is stable, spray cork can create a flexible protective finish.
Is ReveCork different from standard masonry paint?
Yes. ReveCork is a technical cork coating system rather than a decorative paint. It combines natural cork with elastic waterproof resins and breathable technology designed to help reduce cracking, weathering and moisture related issues.
Will spray cork stop cracks coming back?
Spray cork can help reduce the risk of recurring hairline cracks because it is flexible and can cope with minor building movement. However, major structural cracks must always be investigated and repaired properly before any coating is applied.
Do I need to remove all the existing render first?
Not always. If the existing render is stable and properly bonded to the wall, it may be possible to prepare the surface and apply spray cork over it. If the render is loose, hollow or badly damaged, those areas will need to be repaired first.
Is spray cork suitable for older homes?
Yes. Spray cork is breathable, which makes it a strong option for many older and solid wall properties. It allows moisture vapour to pass through rather than trapping it behind an impermeable coating.
How much does cracked render repair cost?
The cost depends on the size of the property, the condition of the existing render, access requirements and how much preparation is needed. Pricing is usually assessed on a case by case basis so the correct repair and coating specification can be recommended.
