What You'll Need
Pressure washer
Weed killer

Bristle broom
Paint roller

Brick paver sealer can save your pavers from absorbing unsightly dirt and stains. It can also make your job of cleaning them easier and can prevent the growth of weeds that might otherwise grow in them. It can even make the removal algae easier when your pavers are exposed to prolonged moisture. Just follow the steps below to effectively seal your brick pavers.

Step 1 - Plan Your Project

This project cannot be done during rain, snow, or hail. So, plan ahead. Watch weather reports that will give you three days of warm, sunny weather. This will include allowing time for washing pavers, drying, and time to apply multiple sealer coats and drying time in between.

Step 2 – Remove Weeds and Grass

Unless your pavers have recently been laid, you will likely find weeds and grass growing between their joints. You'll need to pull these weeds, kill the grass with weed killer, then wait 12 to 24 hours before continuing with the project.

Step 3 – Pressure Wash the Pavers

Accumulated dirt, stains, moss, algae, and even oil or grease stains must be thoroughly cleaned off the pavers. The best way to do this is with a pressure washer. When you've finished washing, clear away any remaining puddles in and around the pavers. They will need to be dry before you continue with the project, so get rid of the puddles with a broom, then give the surface a warm night or an entire day for it to dry.

Step 4 – Rope Off the Area

Prevent all foot traffic from using this surface you've cleaned. Rope it off, attach warming signs, do what you have to do to keep people (and pets) from using this surface.

Step 5 – Apply the First Sealer Coat

When you're sure the paver surface is clean and dry, you can begin applying the first coat of sealer. If the surface is small, such as a small patio or walkway, use a roller to apply the sealer. If applying to a larger surface such as a driveway or large patio, you may want to consider using a spray applicator. If you use the sprayer, be sure to wear old clothes, gloves, and a face mask or goggles. The sealer will quickly soak into the pavers, so try not to mistake surfaces that seem dry because the sealer has penetrated the surface and has made it look dry. Be sure you have covered the entire surface with sealer. Allow 24 hours for this first coat to dry—longer if temperatures are cool.

Step 6 – Apply Additional Sealer Coats

When the first coat is dry, apply a second coat, using the same procedure as with the first coat. If additional coats are necessary, allow adequate drying time between coats, and re-apply more sealer. Continue to keep people and pets off the surface until you have applied the final coat and it has dried.

Step 7 – Cleanup

Follow directions on the sealer for cleaning your roller or sprayer.
