i`ve just been doing residential driveways here. i pressure wash the driveway then roll it on with a roller,let dry for an hour and put on a second coat stick up my caution tape and a sign and that`s it. i spend around 25$ in material and charge a min. of 150$ canadian and it takes me around 2 1/2 hours. this is one sweet web site and is very helpful.sealing it a good income when the grass dries up and stops growing.
