Pavers are a popular hardscaping option that allow you to customize your paved surface to a greater degree than traditional asphalt paving does. However, because pavers are small pieces of natural stone or concrete that are fitted together, weeds can sometimes begin to grow up between them, causing the flat surface of your pavers to become disrupted. Re-leveling your pavers is a complex and expensive task, and so there are a few things that you can do to remove the weeds before they cause damage to your pavers.
What You'll Need
Before you begin, you should gather all the tools and materials that you may need during the process. You'll need a pressure washer, a handheld weed remover (small enough to fit between the joints of your pavers), vinegar, a broom, a bucket, and a bag of sand. You can find all of these items at most hardware and grocery stores if you don't already have them within your home.
Removing Weeds from Your Pavers
First, you'll need to remove any larger weeds that have pushed their way up above the surface of your pavers. To do this, you'll have to use your handheld weed remover to uproot these weeds.
Then, take the pressure washer and wash between any affected pavers to remove smaller weeds and remove any remaining plant and root matter that may remain. This will also clear out the sand used to stabilize and hold the pavers in place.
You can now make a mixture of half vinegar and half warm water together in a bucket, and apply it between the seams of your pavers. This is an optional step, but is highly recommended, as vinegar will kill any remaining weeds or plant matter that you failed to remove by hand or with the pressure washer.
Let the surface of your pavers air dry, which should only take a few hours during a sunny day. Then, you need to refill the seams between your pavers with sand. Though many hardware stores sell specialized paver sand, regular sand will work just fine. Simply pour the sand liberally over the pavers, and use the broom to push the sand into place, until the sand reaches almost to the top of the surface of your pavers. This not only holds the pavers in place, but also makes it harder for new weeds to develop, as their roots will struggle to find purchase within sand.
