Hello,
Thank you for your enquiry.
There is no specific time frame for how long the item lasts before it needs re coating as this depends entirely on location, weathering, porosity of substrate, amount of traffic/wear etc.
It will likely be that surfaces need to be re coated every 18 months ( 1 and a half years). HOWEVER, the manufacturer states that this should be applied as and when needed. Implementing a specific time frame may result in customers waiting too long to apply new coats, meaning that the repellent properties of the product could be compromised,
Thank you for using Q&A.
