ECO.CALIBRE coatings are “superdurable” and “superphobic” – hard wearing substances that reject oil, water, red wine, fruit juices and most acids in liquid form. Treated surfaces are easily cleaned with water alone. They become highly durable with the potential to last for many years depending on how they are treated. Should the coatings show signs of wear, they are very easy to re-condition. Our Stone impregnations act like an unseen barrier against chemical attack and the effects of our environment. These also act as a protector against fungal attacks, moss and prevent crumbling. Other surface treatments that might appear to give a similar result to ECO.CALIBRE are silicone based which are not nearly so durable or effective.
