Hello, on top of my landscape business I am a maintenance coordinator for a church/school and I just had a few questions regarding sealing parking lots and sidewalks as we want to buy our own equipment. We don't want overkill, but don't want junk equipment either as it will get used every year. so a few questions... 1. we have 3 fairly good sized parking lots, I am looking for something that is big enough (but not some giagantic set up) to crack coat and seal coat these lots, is there a good and dependable machine that will do both? I was told a "sealpup II" (from Sealmaster) would be a good machine because it can spray the seal coat and still hit cracks with the change of the tip. I like the sounds of this due to versatility. is this a great machine though? 2. I was also trying to find something to fill sidewalk cracks as well as the parking lot cracks, again was told by sealmaster that an MA10 is a good machine, but I have seen from some comments its not that great, and don't think it would do clear patch for sidewalks. Is there something to fill concrete cracks for sidewalks? we have quite a few sidewalks so it would be nice. anyway, don't want to come on here and overload people with questions, I am researching like crazy but thought I would ask the experts. thanks for the help!
