Hot applied and best suited to tarmac surfaces, it can be used on concrete but should have a tack coat base applied first to offer greater adhesion. The wear rate is good but can be prone to chipping in colder weather and the depth of the line can become too thick due to too much remarking. This can be avoided by removing the existing line and beginning again with fresh application to keep the depth to a minimum. The winter can affect thermo lines on concrete. In winter months, when frost sets in, it can blow the line from beneath as the damp expands due to freezing.
This is the most cost efficient product with the best all round performance. It should not be used on block sets however as with any line it will fail in the joints and may fail in other areas when this happens. If a surface has joints or pot holes there is no product which will stay in place, The curing time is 1.5 minutes for thermo, but any tack coat pre applied takes up to 15 minutes to cure prior to line application.
