The three most important things to do :
1. Clean the surface well. I used a power washer for my paved side walk and patio.
2,Make sure the surface is completely dry and no rain is forecast for the next 24 hours.
3.Apply the 2nd coat ( recommend ) 24 hours later for good application.
The finished job looked very good. The 2nd coat brings out a much better color and a nice satin finish. The vapors are very strong, would not use for inside application. I am sure they have other products for enclosed spaces.
