Installation
The unit weight is 10.9 pounds per gallon (1.31 kg/L). One gallon will seal 150 feet (45.7m) of 1/2 inch (1.2cm) wide by 1/4
inch (0.6cm) deep joint. Exact yield will vary depending on thickness of sealant, waste, application techniques, etc. Prior to use, the user must read and
follow Installation Instructions for RoadSaver Silicone to verify proper product selections, applicator pumps, pavement preparation procedures,
