Hi, my brick pavers are not in great shape. I am looking to either paint or seal. However most sealers are recommended on 100% dry surfaces. Because the pavers are under pergola, they dont get any sun and I can see some moist area. I have tried using some outdoor cleaning chemicals and pressure wash. It has probably been only 6 months and now I can see a lot of white spots, algae etc.
What is the best way to rejuvenate and protect these ? I think these are clay bricks ?
