Paver sealant is a great tool to keep paver driveways, patios, walkways, and pool decks, in mint condition, but it's not always necessary. While it's not a must-have, pavers that aren't sealed typically grow weeds in the cracks, lose color over time, and can even have shifting caused by a lack of joint sand.
If the sealer is not cured correctly, water can cause white marks or stains on your pavers and can even be trapped beneath the layer of sealer. It is very important not to walk or drive on sealed pavers at least 24-48 hours after application. A protective sealer enhances the natural color and beauty of your pavers.
Enhanced aesthetic: The paver sealer enhances the curb appeal of your properties and provides perfect finish to the paved areas and at the same time stabilizes the joint sand by locking it in place. It protects the pavement against harmful UV rays and prevents fading.
For film-forming sealants, you will be able to notice when the physical barrier is showing signs of wear. For non-film-forming sealants, you will begin to see a significant color change of pavers during a rain when the sealant is wearing thin.
Most contractors and manufacturers recommend sealing pavers for the many benefits. Both concrete and brick pavers are porous materials that can change quality and appearance when they absorb liquids.
Fall or spring is a great time of the year to seal pavers. Cooler weather allows the sealer to penetrate into the pavers unhindered. Pavers will have an adequate amount of protection for when it's time to seal again. Make sure to keep leaves and other debris off the pavers while they are drying to avoid blemishes.
The culprits of blotchy concrete after sealing
When you find yourself staring at discolored concrete that has already been sealed, there are usually three potential sources of blame: The sealer was applied poorly. Not enough sealer was applied. The concrete itself had varying absorption rates.
Using a nap roller for sealer application will take several times longer than using a paver sealer sprayer and joint stabilization is difficult to achieve. Spraying is the preferred method of applying water based paver sealers as it allows enough sealer to get into the joints.
You're wondering what happens if you don't seal pavers. Your pavers won't disintegrate if you don't seal them, but they'll likely fade much sooner than if you applied sealant. You'll also need to clean them more often, and the stains won't be as easy to remove.
There are three ways to darken your pavers: sealing, staining, and painting, with the first being the less invasive option. The first thing you need to do before starting any process of darkening pavers is to clean them.

Advantages of Sealed Paver Joints
Although paver sealing does not guarantee complete weed prevention, it remains the most effective way to achieve longer-lasting results in weed control. Simple maintenance tasks and occasional treatment of persistent weeds may be necessary.
Then, about 24 hours prior to sealant application, thoroughly cleanse pavers of any remaining residue with Techniseal's Paver Prep, a powerful efflorescence cleaner that will give you a nice clean surface on which to work. Our paver preparator also maximizes sealant penetration and adherence.
Should Pavers Be Dry Before The Sealing Proccess? Yes, it is important to ensure that your pavers and your pool deck are dry before applying sealer. If they are wet, the sealer will not be able to adhere properly and could eventually peel off and cause damage to the pavers.
Brick pavers absolutely, 100% need to be re-sanded prior to sealing. The sand in the brick paver joints serves MANY integral purposes. Keeps joints stable, pavers level,and fills the void between pavers to keep them from becoming loose and wobbly.
A wet cast brick paver has a more dense and smooth finished surface. Sealing these with certain types of brick sealers will make them very slippery when wet.
If your pavers have been sealed, which is a service that we offer, it's a lot easier to maintain and it does slow down mold growth for the simple fact that when your pavers are unsealed, that moisture will sit in the joints and make mold grow. Mold likes damp, dark areas.
If it still happens to rain unexpectedly, don't apply more sealant over the ruined coat because this will make it even harder to fix it. Instead, use a solvent specifically for the type of sealant that you are using. Solvents can liquify the ruined coat of the sealant and will give you a fresh start.
If a white haze appears on sealed pavers, it is less likely that the white spots are efflorescence but rather, water condensation collecting underneath the sealer. Removal is still possible, but a chemical solution is required. If your sealer is oil-based, the fix is to re-emulsify the sealer with Xylene.
The pressure washer in combination with a dirt cutter is an excellent option. This removes not only weeds and moss from the surface, but also from indentations. Keeping up with this type of cleaning means that there is less time for weeds to grow. It also helps to maintain the beauty of the paving stones' surface.
