CLEANING AND SEALING
So, you may be wondering how to keep your paver patio or driveway looking as beautiful and strong as the day you got it. One way to further improve and maintain the look and durability of your pavers is by cleaning, sanding, and then sealing.
Over time, depending on the brand of paver, elements like wind, water, and the sun can fade your patio paver colors. Unsealed paver joints will wash out, weeds will grow, and ants will start invading your installation. Sealing pavers is a great way to prevent or reduce these unwanted effects of time on an unprotected patio or paver driveway.
Properly cleaning then sealing your old or new patio installation, will protect it from stains, salt, and water damage. It will also make it possible to easily maintain. Sealed paver surfaces make it easy to wash away dirt and algae build up from the surface of the pavers, without having to use high pressure washing or harsh chemicals to clean. The sealer will also harden the sand in the joints, making the whole patio or driveway structure stronger as well as deter weed and moss growth. Sealing paver joints, also prevents water, ants, and wind from carrying away the sand between the joints, which would require you to constantly replace and refill.
Sealers can be applied every year or every two years. In general, a good seal will last you around 3-5 years, although you can reseal whenever you think the appearance or durability of the surface requires it.
