A Guide to Paver Maintenance (Part 2)
In part one of this guide we covered how to clean weeds, algae, and stains from your concrete patio pavers and pool coping. Here in part two, we give individuals the final tips required for the maintenance and beautification of their patio and driveway pavers. Below you’ll find ways to restore your pavers from the effects of oil stains, paver efflorescence and uneven patio pavers.
Cars parked over concrete driveway pavers can cause oil leaks. In the event of an oil or petroleum leak on your pavers, act fast! The longer you wait the deeper the oil will penetrate into the paver. Stains should be treated quickly by absorbing up as much of the oil as possible, either with a paper towel or rag. Apply liquid detergent (a highly concentrated dishwashing detergent should do) and allow it to soak into the stained area for several minutes. Then, wash the pavers with hot water, adding more detergent as needed. In extreme cases, you may have to replace the stained paver with a new one.
Paver efflorescence is a naturally occurring process that begins to happen to some pavers shortly after installation. You may begin to see a white film covering the surface of the paver and may start to get worried. Rest assured, paver efflorescence is a completely natural process that all concrete structures go through. The white haze will stop when there isn’t any more calcium hydroxide available to move to the surface of the tile, a process that usually lasts about a year after installation.
If you wish to remove this efflorescence, and give more color to your paver tiles use efflorescence cleaners. Use the cleaner in a small inconspicuous location to see how the paver reacts before undertaking the whole project.
Uneven Patio Pavers
When patio pavers start to become uneven (i.e. when the corner of a paver is jutting out) there is usually a problem with the structure underneath. Depending on erosion and weather exposure you may need to replenish the sand underneath the paver joints periodically. Additional sand can add traction and fix misalignment between concrete pavers.
