A patio, driveway, or walking path to your home can be a great finishing touch, and using brick pavers for these projects can make it easy. Get some general information on sealing and then follow some simple steps to seal your new pavers.

Why Seal Them?

Sealing your brick pavers not only keeps them looking new and beautiful, but provides a protective layer between the bricks and the elements. There are a number of finishes you can choose from. If you prefer a natural look to your pavers, you will want to steer clear of a high sheen.

When to Do It?

Typically, sealing should be done every couple of years. If you are not sure of the condition of your former seal, see if water beads up on the surface of the brick. If it does not, it's time for a new coat.

Step 1 – Prep the Brick

If you hire professionals, they will apply a chemical wash to your brick pavers to clean them. However, you can do it yourself with a mild cleanser and water. Use a scrub brush to remove any stains or hard dirt that has taken hold on your pavers.

Previous coats of sealer can be removed by sanding, although this is not really necessary. It’s not a bad idea, however, if you're trying to get rid of trapped moisture from a past sealing job.

Now use your high-pressure attachment for your hose to spray away your cleanser and all debris that has collected on the surface of your pavers. Remove any excess water and allow the brick to completely dry. This is important as any moisture that gets under the sealer will cause white spots on your pavers and will be difficult to correct without starting the whole process over.

Step 2 – Brush or Roll on the Sealer

Using a brush or a roller, apply the sealer to the brick pavers. Use light strokes and be careful to keep large amounts of sealer from building up in any one location. By keeping it even, you'll help with the drying time and the finished appearance of your brick paver sealer.

You'll want to start in a back corner and work your way out so that you don't get yourself stuck. Take a moment to figure out where you'd like to end so you can walk away without having to walk across the wet sealer, and then start in the opposite corner.

Leave the sealer to dry for at least a couple hours. However, it is best to let it cure for a full day before resuming regular traffic.

Step 3 – Restore Sand if Needed

If the cleaning process removed some of the sand between the pavers, you may want to replace it at this point. The sand holds the pavers in place and does not need to come all the way to the top of the pavers when refilling.
