Interlocking pavers are not actually linked to each other. Instead, the pavers are locked into place by first properly preparing the surface underneath the pavers, and then filling in the joints between them with sand to hold them in place. The last step in locking pavers is to apply multiple coats of sealant. Most pavers are made of either bricks or concrete. You seal both brick and concrete pavers with the same method.
Things You'll Need
- Scrub brush
- Brick (or concrete) stain remover
- Acrylic-based sealant
- Paint roller
- Paint sprayer
Hose down your pavers with a garden hose.
Create a sudsy solution of water and a household detergent in a bucket.
Pour the solution on top of the pavers and allow it to sit for 15 to 20 minutes. Scrub the solution into the pavers with a scrub brush or stiff-bristled broom. Rinse off your pavers with a hose.
Inspect your pavers for any deep stains that are still visible after the cleaning. Clean your pavers with a commercial brick or concrete stain remover. You can find these products at home improvement stores.
Inspect the joints between the pavers to see if they have the adequate about of sand. The sand, which helps hold the pavers in place, should be roughly halfway as high as the pavers. Fill in any joints that need sand. Place sand on the bricks and sweep it into the joints of any pavers that need it. The sand should reach halfway up the side of each paver. Sweep off any leftover debris or sand with a broom.
Use a paint roller to apply a coat of acrylic-based sealant over the pavers in long, smooth strokes. Spray the sealant on the pavers for large areas with a paint sprayer. Spread out any excess sealant over the pavers.
Allow the sealer to dry for the time recommended on the label. Add another layer of sealer after the first one has dried.
Tips & Warnings
- A third, or even fourth, coat of sealer might be a good idea if you have harsh weather in your area. Apply extra coats if you also want to darken the color of your pavers. Pavers should be sealed at least once every two years. The joints should be filled with sand on a yearly basis.
