Acoustic insulation goes hand in hand with thermal insulation. A coating can absorb up to 38dB of noise, giving occupants of roadside properties a more peaceful life.


Reduces Maintenance

A cork coating vastly reduces your future maintenance costs and worries. At a fraction of the price of a total re-render, a spray cork coating for your rendered home is a sound investment, giving total peace of mind.


Natural and Sustainable

No trees are felled in the production of Spray Cork. The cork in our material is harvested, leaving the trees to regrow. As they do so the forest’s CO2 absorption increases. This incredible natural process means that cork content in Spray Cork coating of the average UK house is enough to offset over 500Kg of CO2 emissions.

    2.3 million houses in the UK suffer from cracked or defective render

    Render defects cause serious problems for your home and are more expensive to repair the longer you leave them. Even small cracks can let in penetrating damp, encouraging rot and mould, and increasing heat loss through walls.

    As climate change brings more wind-driven rain, and with the destructive effect of winter frosts, problems only increase over time, eventually requiring an expensive total re-render. Many homeowners report that a total re-render is one of the most expensive costs of their life.

    Ensure this doesn’t happen by spotting the early warning signs. Cork render can be applied onto failing renders due to its elasticity, all while keeping the 25 year warranty intact.

    No, it is a textured finish. It’s slightly stippled, and it is the granulation of the cork which gives it its performance.

    Yes, it is possible to go over existing renders and other substrates and still get a 25-year product warranty. However, just to manage expectations, SprayCork will not hold your wall together so any blown or shot render will need to be rectified first. For example, if you have sand and cement render which is painted and has hairline or settlement cracks, as long as the substrate is solid you can go direct onto the render. The best thing to do is get an Approved Applicator to do a site survey and they will be able to advise you.

    Yes, absolutely. Spray Cork will go directly onto pebble dash, roughcast, dry dash, wet dash or stippled paint. Please note the overall thickness of SprayCork is around 6mm so the texture of the dash will still be visible. However, the finish will look more subtle and is very effective. If a smoother finish is required, a base coat will be needed first.

    Yes, Spray Cork will stick to any substrate (apart from silicone), including brickwork. As the overall thickness is around 3-4mm you will still see the mortar lines of the bricks. If you want a smoother finish a base coat will need to be applied before spraying the cork. Either finish looks effective so it is purely personal choice and/or budget. If the bricks are dusty a primer may be needed but the Approved Applicator will advise on this. If any pointing is missing this will need to be repaired prior to spraying.

    This is probably the most asked technical question. We don’t give a U-Value for the product on its own as that is determined by the complete build of the wall. If you wish to calculate the U-Value of your wall, SprayCork’s Lambda value is 0.058W/mk. We have test results which demonstrate the potential reduction in the U-Value, and these may be viewed in the blog section of our website. As SprayCork is one continuous skin with no joins or gaps, it improves air tightness of the walls which isn’t measured in U-Value testing.

    We have a standard colour range with 28 fade resistant colours. We also have a colour pigment machine in house which can make up to 1800 colours so if you have a specific RAL code we can make this colour (min order required 300m2 or development cost on smaller orders) for any commercial property orders.

    Yes, you can jet wash the cork but don’t get too close. If the pressure is too high, it will damage the cork (pressured water is a very effective blade!). Cork has anti-microbial properties and naturally resists against algae but an annual clean is recommended.

    The product warranty is for 25 years. The warranty covers any issues with the product failing. It excludes damage caused to the product after installation or poor workmanship.
