Why should I seal my pavers?
Paver sealing performed by a “professional applicator” will reduce sun, wind, and rain erosion on the surface. Legit paver sealer companies will always clean, re-sand, and seal with with professional products which will also prevent fading, staining, chipping, cracking, and discoloration.
Paver sealing is the best way to protect your driveway, patio, pool deck or walkway. Most pavers have a thin face mix that covers the top of the stone. This face mix wears down from exposure to the elements such as sun, rain erosion and tire friction. As a result Paver sealing increases the longevity of your pavers while enhancing their natural beauty. Sealing pavers provides a hard transparent coating over the surface of the paver stone. Therefore the sealing process helps to minimize staining, weed growth, and ant mines that tend to take over the joints. If you have pavers get them sealed.
Paver Sealing Myths
Myth 1: All sealers are the same. Contrary to the belief not all sealers are the same. There are water based and oil based sealers. We live in Florida with a lot of moisture not including a high water table. Water based paver sealer will allow any trapped gases and efflorescence to pass thru the sealers surface.
Myth 2: All paver joint sand is the same. Incorrect we prefer using silica sand which has no nutrients, it course, it’s a base sand. We have found that play sand can turn GREEN in color which can become a nightmare.
Myth 3: All pavers are the same. No not all pavers are the same. Pavers have different porosity rates. There are even different qualities of pavers.
Myth 4: Paver sealing is a permanent solution. Sealing Pavers requires maintenance. Just like waxing your car paver sealing requires maintenance coats to be applied every two to three years.
Myth 5: Sealing Prevents mold and weeds. NO. Sealing does not prevent mold and weeds. At best with the right sand it will slow down and inhibit the growth of mold and weeds, but it will never prevent it, nothing ever will and no amount of sealer will be able to prevent mold and weed growth.
Maintaining your Sealed Pavers
Your pavers will look better and lasts longer with proper care and maintenance. Here is what you need to know.
After performing lawn maintenance simply blow off any dirt, dust, leaves, and grass clippings. You will not believe how much EASIER this task will be!
Occasionally you might accidentally run over a frog, lizard, candy bar, etc… However it may happen. In these rare instances you will probably find them baking in the sun. When these unfortunate conditions occur simply rinse them off with your garden hose. We recommend starting out with a “fan” or “shower” spray pattern, and avoid using higher pressure “jet” patterns as this may loosen the joint sand between your pavers. Decaying debris left to accumulate will create an environment for organic (mold) growth.
Mold, Mildew, Algae
Now that your surfaces are sealed, you’re going to get great protection against mold, mildew, and algae penetrating into the pores of your surface. However, with our climate there is always a potential risk that organic growth will take place. Conditions where you have poor water drainage (Ponding), and/or where dirt and mulch tends to wash out from flower beds onto your pavers are going to get dirty. The simplest and most effective way to remove organic growth is to treat it with bleach. Mix 1 part bleach to 2 parts water and apply using a spray bottle, pump sprayer, or watering can. Make sure to wear
protective clothing, gloves, and eye protection. Let it sit on the surface for 5-10 minutes, and then rinse off thoroughly with a low pressure rinse from your garden hose. NEVER USE MURIATIC or SULFURIC ACID as this could damage the sealer and surface. Multiple applications may be required. DO NOT pressure wash your pavers for at least two years after being sealed.
Typically, our clients experience a 90% to 95% reduction in weed growth on properly draining paver hardscapes with properly installed concrete paver edge restraints . Everyone’s situation is different. Driving automobile tires over the edge of the paver driveway will eventually crack or break the concrete thrust blocks that keeps your pavers tight. Therefore, broken concrete edge restraints will allow your pavers to spread apart and allowing organic debris to fill the joints. Weed growth is beyond our control if your pavers are spreading apart.
Sand Wash Out
Our paver sealer stabilizes the joint sand, however, some sand wash-out can occur if your paver concrete edge restraints are broken. Downspouts that discharge rain water onto your pavers, or if you have a section of roof that really should have a gutter installed are also areas where your joint sand could start to wash out over time.
