The time it takes for a surface to cure is dependant on a number of factors including screed depth, type of resin (UV or non-UV), air temperature, ground temperature and relative humidity. This means that calculating an exact curing time is incredibly difficult. The resin starts to “skin” and cure as soon as both parts are mixed together and a method should be used to ensure that mixes are barrowed to the site when they are needed and that the “wet edge” does not start to dry before the next mix is ready to screed.
Generally, the surface is tack-dry within four hours of laying and may be ready for foot traffic. If the surface is to be driven on, it is recommended that 24 hours should elapse before driving a vehicle on the surface. If possible, all installations should be afforded the full 24 hour curing time before use.
