Most pool pros recommend sealing concrete deck pavers to protect against moisture intrusion, discoloration, and pests. But you might wonder if it’s really a necessary part of pool maintenance. Join us as we discuss the benefits of paver sealer, the best styles, and whether professional sealing services are worth it.
Why Paver Sealing Matters
Sealing your concrete paver deck is important for the surface's longevity. Here’s why:
Water Resistance and Structural Protection
Your concrete pavers should be water-repellent to prevent extensive moisture from seeping inside and beneath the deck. Although it won’t prevent cracking and shifting on its own, a properly sealed system can provide an added layer of protection against structural damage.
For optimal results, use it in addition to a solid foundation, proper drainage, and high-quality, professional deck installation.
Color and Finish Preservation
Here’s where a concrete sealer really pulls its weight. Concrete is prone to fading and staining, especially when exposed to UV rays, pool chemicals, sunscreen, and other contaminants. A suitable sealer can reduce the risk of discoloration and even enhance the surface, resulting in a more refined finish.
Is It Necessary to Seal Pavers?
Technically, you don’t have to seal concrete deck pavers. Some high-quality products may maintain their visual appearance without it, but this maintenance task offers benefits beyond aesthetics.
A compatible concrete sealer helps hold polymeric or joint sand in place, reducing the risk of erosion and movement. By stabilizing the substrate, you can also reduce weed growth and insect activity, both of which can compromise the underlying foundation. Finally, a protected surface may withstand mosses and mildews better, requiring less aggressive cleaning and maintenance.
Types of Paver Sealers
So, which paver sealer is right for your concrete pool deck? Let’s take a look at the most popular types of concrete sealers to help you decide.
Wet Look and Natural Look Finishes
Acrylic gloss sealers create a film over the material’s surface, forming a protective layer that keeps out water and other contaminants. These typically result in a shiny, wet look that enhances the existing colors and textures of the pavers.
Natural look finishes work the same way but leave behind a lower sheen. In turn, they retain the appearance of unsealed concrete.
Penetrating (Water-Repellent) Sealers
Penetrating concrete sealer absorbs into the tiny pores of concrete, providing water resistance from within.
Water-based formulas leave a matte or satin finish that typically doesn’t alter the appearance of the concrete. Many people opt for these solutions because they’re easier to work with, can be removed with soap and water, and emit less odor and fewer emissions than those made with solvents. However, they may require more frequent maintenance.
Solvent-based sealers offer strong penetration and water resistance, making them more durable in high-traffic areas and harsh weather. Some darken the concrete, leaving a shiny finish. The downside is that they are highly flammable and produce harsh odors and elevated levels of volatile organic compounds (VOCs).
How Often Should You Reseal Pavers?
Depending on foot traffic, chemical exposure, and sun exposure, you can expect to reseal you pool deck pavers every two to five years. But while a calendar can be helpful for timing maintenance, it’s best to reseal when pavers show signs of wear, such as:
-
Water absorbs faster or no longer beads on the surface
-
Diminished color enhancement or sheen
-
Increased susceptibility to staining
-
Joint sand becomes unstable
-
Surface appears weathered, chalky, or flaky
DIY vs Professional Paver Sealing
It’s possible to apply paver sealer on your own, but there are certain risks associated with DIY sealant jobs. Here are a few considerations to keep in mind before taking on the task:
Application Method Considerations
Applying paver sealer isn’t always a straightforward process. Certain mistakes, like ignoring concrete preparation or sealing over trapped moisture, can cause haziness and interfere with the curing process. Meanwhile, temperature, humidity, and weather conditions must be right to prevent costly — and expensive — mistakes.
Once you’ve accounted for these factors, you must decide if you’re using spray-on or roll-on paver sealer. When spraying sealants, be mindful of spray rate, overlap, and product volume to avoid heavy applications. Be sure to wear a respirator or mask and protect nearby furniture, landscaping, walls, and pool equipment from overspray.
Roll-on sealants offer more control, but require consistent pressure and overlapping passes to coat the surface evenly. This can be particularly tricky with heavily textured or irregular pavers.
Long-Term Value of Professional Sealing
Professional resealing services help protect your deck investment long term. An expert will know which product best suits your needs and have the skills to help ensure a successful application. They can also identify damaged or shifting pavers that need attention before treatment.
You might feel tempted to seal your own pavers, especially if your deck is small and you have experience with DIY projects. But folks who are new to paver sealer will benefit from an expert opinion.
