Our patio and home are 43 years old. Over the years the patio has developed some uneven sections that have been corrected with mud-jacking. Now we are considering rejuvenating the look of the patio by having it professionally stenciled. We’ve been told that they clean the patio, then spray the color of our choice then use a stencil (in our case we are thinking of a brick pattern) so we have a brick “looking” patio. Our question is; what are your thoughts on the process and do you have any idea on how this look holds up over time?
