|Before Power washing and sealing
Our front walk, side driveway and backyard are comprised of paver stones. They are nicer than asphalt or concrete but do require some maintenance upkeep. I did my Google and YouTube research and found that paver stones require you periodically sweep in paver sand between the joints at least three times a year. This keeps them from moving and if they were installed properly (level) then you don't have too many puddles after a big rain.
|After: sealed and power washed
My research yielded a chemical enhancer/sealer that you can apply to paver stones to keep them looking good. Unfortunately, again the enhancer doesn't do much to my type of paver and at $50 a half gallon, it is cost probative for me to do my entire backyard and driveway, so only the front walk got treatment.
It might be hard to notice the difference in the pictures. I meant to take better before and after pictures but it was a very busy week when I did this project and I had a short window between good warm weather to dry the sealer and the upcoming storm. I got a deal on a power washing on Angie's List so I outsourced that part.
