Why Seal Brick Pavers

Brick pavers have become increasingly popular among homeowners in recent years. Areas around the home such as patios, porches, sidewalks, and driveways can be created with brick pavers and can certainly enhance the beauty of your property.

It is however important to note that like concrete, wood, and other surfaces, brick pavers will last longer if they are maintained regularly. The most beneficial thing you can do for your brick paver areas is to apply a brick paver sealer. When pavers are not sealed they can suffer from effects of erosion, weed growth, mold/mildew buildup, sun fading, ant activity, and discoloring. In extreme cases, brick pavers can shift, become loose, or settle causing low areas where water can puddle.

Brick pavers are normally laid on a bed of special sand (polymeric sand) that keeps them level and somewhat stable. The bricks are spaced evenly apart leaving a small gap in between. Additional sand is then poured onto the laid brick pavers and swept around to fill in the spaces and gaps. The excess sand is blown off and the new brick paver area is installed.

After a new paver installation, or after pressure washing an older paver area and re-sanding, a brick paver sealer should be applied to waterproof the surface. Applying a brick paver sealer will solidify the sand joints and help to lock the bricks in place. A brick paver sealant will also reduce weeds trying to grow up between the bricks. Because water beads up and will not be able to penetrate, mold and mildew are less likely to occur.

Another benefit or reason to apply a brick paver sealer can be to enhance the appearance. Though there are brick paver sealers that will protect the pavers without altering their appearance at all, there are some that can enhance it. Some brick paver sealers can provide a glossy sheen or “wet” look which many homeowners are in favor of. Not only do these brick paver sealing products enhance the natural beauty of the pavers with a shiny gloss look, but they too waterproof and protect against the elements.

Sealing brick pavers can be a do-it-yourself project if you feel comfortable or it can also be hired out. The important matter is that the brick pavers and sand joints are protected from harsh weather conditions, water damage, weed growth, mold/mildew, anthill activity, and sun fading. Sealing brick paver areas and keeping them maintained will ensure prolonged beauty and many years of use.

    Thinking about sealing our brick pavers on the lanai and around the pool area. They are the thin pavers as they were installed on top of an existing cool deck a couple of years ago. It seems very confusing to hire the right company for the job. We got estimates for oil based and water based sealants and were told that oil based sealant should last approx. 5 yrs vs the lifespan of 2 – 3 yrs for water based sealant. Which one is best for Florida?

    • Concrete Sealer Help says:

      William, what type of sealers are these? Wet Look/Gloss paver sealers will last about two years. Nothing will last 3-5 if this type. A non color or enhancing sealer (no change in appearance) that water repels can last 3-5 years.

    another question
    Tucson az
    I had a paver sidewalk laid last fall and they put concreted between the outside pavers to keep everything in place.
    I now want to use Behr stain on the concrete part. I would then like to seal everything. What would be best products. From what I have read a gloss makes the pavers stand out.

    When pavers are sealed around pool, do they become very slippery?

  5. joannes says:

    I used Home Depot sealer 3 years ago to seal my pavers around my pool. I still have "white" showing on my pavers. I do not know what caused this white, if it was from the sealer or the sand. I had "reps" come over to see how much it would cost to have them stripped. They said they would not do it because it will ruin my pool, the cage around the pool, and the pool. What would you recommend.

    • Concrete Sealer Help says:

      It was the sealer that caused this. Your options are to strip or replace. There is no other options. Sorry.

      • Lori says:

        Why do you say it was the sealer? Efflorescence is the chalky white look that develops on many pavers from naturally occurring salts in the raw materials pavers are made from. Even with sealed pavers, this white substance can com out of the pavers, which is why it's not recommended to apply sealer on new pavers, but to wait until the natural substance is fully emitted and washed away with the proper cleaners.
        It's also strange for you to say it was the sealer as it completely contradictss what you stated above as the benefits of sealing.

        • Concrete Sealer Help says:

          Because Home Depots sealer turns white itself. It is a poor acrylic sealer and has numerous issues and complaints from owners that have tried it. This particular scenario has nothing to do with efflorescence.

    I live in Naples Florida and would like to seal my pavers. The pavers have be sealed with a water base sealant Can I use something other then a water base or do I have to stick to water base ?

  7. Marty says:

    generally speaking, how much product does one need per square foot.? Looking at Semi-glss sealer for my brick pavers. Is that what you would recommend since the high gloss isn't pretty to me….live in /florida…..

  8. David says:

    I have been told mixed information about sealing my pavers. I laid down 68 x 4 foot walkway of cement flagstone pavers up the side of my house last summer. I would like to seal my pavers and give them a wet look to really make the walkway stand out and keep sand in joints. My only qualm with this is i have been told this will severely reduce the life of my walkway. Essentially causing the pavers to "rot" from the inside out. Is this true? Will i have to strip and reseal the walkway often? I have hundreds of hours into that project and i just want the most longevity possible out of my walkway thanks. Dave

    • Concrete Sealer Help says:

      No that is not true. Using a breathable paver sealer will prevent this. Try the Super Seal 30 or the Super Seal25. Both can be cleaned and reapplied every 2 or 3 years.

    just pointed brick patio – need to prevent mortar from coming loose again-what is best product-can it be applied by spraying

    • Concrete Sealer Reviews says:

      Sealers will not stop mortar from coming loose. Are you trying to enhance the paver bricks or just seal?

    We had our pavers sealed but there is still loose sand…did they miss some spots?
