Over time, your old brick or stone patio pavers can become dirty, grimy, or dull in appearance. Paver cleaning and sealing should be performed on a regular basis to keep them clean and looking like new again. Cleaning pavers is really rather easy when you follow these steps.
#1. Sweep your pavers clean to remove leaves or other debris, then remove any weeds from in between them by hand. If your pavers are covered with moss, scrape it gently away with a putty knife.
#2. Spray the surface of your pavers down using a garden hose with spray attachment. Ideally, your pavers should be thoroughly wet but not so soaked that there is standing water on top of them.
#3. Place a few drops of mild dish detergent in a bucket of warm water and slosh thoroughly to mix. Alternately, you may also use a special cleaning product designed for your particular type of paver, something that can be purchased at your local hardware or home improvement store.
#4. Pour a bit of your cleaning solution onto your pavers. Using an outdoor push broom, gently work the solution back and forth a bit to loosen any caked-on dirt and grime. If it has been a little while since you last cleaned your pavers, you may even want to let the solution sit for a bit.
#5. Use the spray nozzle on your garden hose to rinse the cleaning solution from your pavers. Depending upon the results, you may need to repeat this process more than one time. Keep in mind that rinsing with a pressure washer might eliminate more grime, but that you also run the risk of damaging your pavers if the water pressure is too high.
#6. Cleaning your pavers will remove some of the sand between them, meaning you must refill this space after cleaning. Gently pour a little bit of sand over top of your pavers, then use a broom to sweep it into the joints. Once the sand is in place, mist your pavers lightly to allow the sand to settle.
#7. Reseal your pavers using a sealant designed especially for your type of paver. Use a roller brush with a long handle, making long, smooth strokes to ensure even coating.
#8. Allow the first coat of sealer to dry for at least 8 hours before adding a second coat. Avoid walking on or using your surface for at least 24 hours after applying the second coat.
