I've spent a lot of time trying to weigh the pros and cons of the two methods of driveway sealcoating (as a consumer). From what I've read it sounds like the advantages of each of the methods can be summed up as follows: Coal Tar Lasts longer Protects better (against oil and gasoline leaks) Fills small cracks better (protects better against freeze/thaw cycle) Asphalt Emulsion Looks better (even, less-streaky application) Easier and faster to apply (meaning labor is less expensive) Fewer fumes Possibly better for the environment What changes would you make to these lists? Can Coal Tar sealer be applied via spray? All of the local contractors I've spoken to want to apply asphalt emulsion sealer. I would prefer coal tar and am wondering if contractors can apply coal tar via spray. I'd appreciate any comments from people who know sealcoating. Thanks!
