Installation and Maintenance
Лучшие практики
Putting up Class 2 reflective sheeting the right way makes it last longer and keeps roads safe. Workers need to clean and dry the spot before sticking on the sheeting. If there is dirt or water, the sticky part will not hold well and the sign will not last as long. Marking where to put the sign helps drivers see it better and keeps roads safer.
Manufacturers give step-by-step instructions for using the adhesive. Installers must follow these steps and let the glue set all the way. If they skip this, the sheeting might peel off or not shine as much. The weather and temperature are important too. Installers should pick the best glue for the road surface. Epoxy resins are good for asphalt, and butyl pads are better for concrete. It is best to install signs when the weather is dry and not too hot or cold.
Reports show that doing all these things makes Class 2 sheeting last longer and stay bright. Councils that use these tips have fewer broken signs and signs last longer.
Checking signs often keeps them working well. The IRC Code 67 says to check and clean signs two times a year. Inspectors look for signs that are faded, peeling, or hard to read. If a sign has any of these problems, it should be changed right away. The posts and mounts also need looking after. Cleaning and painting them every two years helps signs stay strong and easy to see.
