However, many of the good qualities of the additive are offset if a contractor adds more water than recommended. The strength of the coating will always come from the coal tar or asphalt. Adding more water than recommended results in a thinner coating and less coal tar on the asphalt. Also testing shows that post adding latex is not as advantageous as the manufacturer incorporating the latex additive in the manufacturing process. You may consider buying premium sealer which takes full advantage of the additives.
Marking is and always be a factor in the pavement coatings industry.
Any marking will go away after 2-3 weeks when all the moisture escapes leaving a fully cured coating. The contractor can reduce the marking by allowing the first coat more time to dry. Finally adding a little more sand can help because the car tires ride on top of the sand. In coal tar emulsions are compounds like naphthalene, creosote, and others with acidic character are skin irritants. These chemicals when mixed with the moisture on skin can cause a chemical burn.
