How many coats of seal coat do I need?
Generally two coats are sufficient if the pavement is clean. If it is not then you may want three with the first acting as a kind of tack coat helping the next two adhere to the surface.

If you are intalling an ISSA (International Slurry Seal Association) based Slurry Seal you will need one coat.
