After: The sealant goes on wet but dries without any evidence that the agent has been applied so there will be no visible difference to the brick's appearance (i.e. no shiny film or cloudy residue).
Before: Split face block is very porous and susceptible to water penetration.	After: Split face block treated with a decorative waterproof coating penetrates deep into the substrate allowing it to become resistant to water infiltration.  These waterproof coatings come in hundreds of colors to choose from.
