on both brick and mortar.
Closeup of brick and mortar mostly cured in this photo.
This is the same brick shown in the other two pictures.
It has had two applications and then 72 hours after the last
application; it was power washed every day for 2 weeks.
This picture was taken at night with a standard white spotlight.
Notice how clean and free of dirt, efflourescence, and hard water deposits.
Shortly after this photo, I put the final coat on.
I will post it when it is totally cured.
