If your sealant is applied to pavers that are too hot, your pavers will become stained, and may start to peel and age prematurely. Note that solvent-based sealants evaporate faster, so lower temperatures are better for application.
Once sealed, you will have to regularly reseal your pavers, particularly if you use a thinner sealant that starts to break down and develop a film over time. The frequency at which you will have to reseal depends on the material of the paver and the brand of the sealer.
The basic rule of thumb is every 3-5 years. 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.
Unfortunately, Brick Paver and Decorative Concrete Sealers sometimes fail by discoloring and turning milky white or yellow in color. Typically this happens for one of these reasons: Moisture was trapped under sealer. Efflorescence (white salt deposits) was not removed prior to sealer application.
You can try cleaning the pavers with a mixture of water and mild detergent. Another option is to hire a power washing company to do a low-pressure wash. Other more aggressive options include sandblasting and a chemical cleaning. We always recommend you hire a professional to ensure you do not damage your pavers.
You need 48 hours of dry weather after your sealer has been applied to cure it. (Remember to turn off your automatic water sprinklers.) 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.
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.
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.
Choosing to seal your pavers will keep your color consistent and un-faded. Not only does choosing to seal your pavers keep the color untouched, but it can also increase the vibrancy of your colors. One largely agreed upon benefit of sealers is that they limit stains.
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.
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.
You pressure clean the pavers, re-sand the paver joints and then apply two coats of your favorite paver sealer and the job was complete.
Don't get me wrong; your brick pavers need to be sealed! However, you want to wait a minimum of 30 days after installation (in Florida) before you have them sealed.
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.
Acrylics. Acrylic paver sealers, either solvent- or water-based, offer the most comprehensive ultraviolet (UV) resistance. Acrylic sealants can be breathable, depending on their solid content.
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.
The solids content of these sealers is very high which fills the paver pores and creates a solid layer of sealer on the surface which will make things slippery when wet.
Some sealers have high solid content, which can fill up the pores on brick pavers. Brick pavers will then develop a solid layer that can become slippery under wet conditions. Inferior quality sealers have this flaw and they often have a very shiny surface.
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.
Is It OK To Pressure Wash Pavers? As long as it's done carefully, cleaning pavers with a pressure washer is ok. However, it's important to remember that after the process, you need to apply a sealant again; which is a substance that considerably increases pavers' durability.
Sealer Turned A White or Cloudy Color
A white or cloudy color is caused by moisture that is trapped inside the sealer.
Efflorescence occurs when water-soluble salts within concrete migrate to the surface and react with carbon dioxide to form calcium carbonate. This substance remains visible on the surface of the hardscape products like pavers, slabs and walls in the form of a white haze.
