Why Contractors Prefer Factory-Sealed Pavers
Historically, post-installation sealing has been the primary method for enhancing concrete paver protection against stains, weathering, and fading—until factory-sealed pavers offered a more consistent and efficient alternative. While effective, sealing on site can be a time-intensive and unpredictable process. Uneven application, sudden weather changes, surface stains and poly-hazing during sealing can result in rework and increased project costs.
Homeowners are increasingly seeking low-maintenance outdoor living spaces they can enjoy immediately. Factory-sealed pavers offer a solution that meets the needs of contractors and homeowners alike—delivering consistent quality, reduced installation time, and long-lasting surface protection. For homeowners who want a patio that's ready to enjoy from day one and built to last, pre-sealed pavers deliver lasting surface protection without adding extra steps to the installation. For contractors, factory-sealed pavers streamline installation by removing the need for post-sealing, reducing delays and eliminating sealing-related challenges to help ensure projects are completed on schedule.
Challenges of On-Site Paver Sealing
Traditional paver sealing requires multiple steps, with every step adding potential for delay or rework. Contractors offering paver sealing services need to wait at least 28 days for newly installed pavers and polymeric sand to fully cure, leaving surfaces exposed to stains and UV damage. Surface prep before sealing often involves chemical treatments or power washing, which can damage the surface of the pavers. Pressure washers may also remove joint sand, requiring re-sanding and re-compacting, which delays the sealing process.
Applying paver sealer requires precision to avoid overspray and achieve a smooth, even finish. Weather adds uncertainty to the sealing process, as specific temperature and moisture conditions are required for proper application. Even after successful application, the patio must dry and cure in ideal weather conditions for 24-48 hours before it’s ready for use.
Even when all application steps are followed perfectly, the protection from field-applied surface sealers only lasts two to three years.
Advantages of Factory-Sealed Pavers
Factory-sealed pavers offer an alternative that eliminates the challenges of traditional paver sealing and provides longer-lasting protection.
Because sealing is completed in a controlled environment, every unit offers consistent coverage and performance. Patios can be installed and enjoyed on the same day. Surface protection is built in, so stains from food, dirt, oil, and more can be cleaned easily without added treatments.
However, not all factory-sealed pavers are created equal. Stain resistance, color retention, finish quality, and surface protection can vary significantly depending on the manufacturing techniques.
Factory-Applied Penetrating Primers Offer A Single Layer of Protection
Some paver manufacturers offer factory-sealed pavers that feature a penetrating primer. Compared to an unsealed paver, this primer delivers improved stain resistance, enhanced color, and UV protection. Additionally, there is a reduced risk of efflorescence and added defense against deicing salts, making them a more resilient choice for climates with freeze-thaw cycles or heavy foot traffic.
Sentinel Sealed Technology™ Offers Two Layers of Protection
County Materials is defining a new industry standard with Sentinel Sealed Technology. Unlike field-applied sealers or single-layer primers, County Materials’ Sentinel Sealed Technology is a hybrid paver manufacturing system that bonds two protective layers—a factory-applied penetrating primer and sealer—to the pavers’ surface.
Pavers manufactured with Sentinel Sealed Technology provide maximum stain resistance and protection from mud, dirt, grease, oil, red wine, and more. The result is deeper, richer, long-lasting color and an ultra-smooth finish ideal for pool decks, patios, and barefoot-friendly spaces.
Our factory sealing process helps prevent common issues like efflorescence or polymeric haze, ensuring the paver surface looks clean and visually uniform. Pavers manufactured with Sentinel Sealed Technology offer significantly longer-lasting protection compared to field-applied sealers or single-layer primers. For contractors, this translates into fewer callbacks, lower labor costs, dependable performance across every job site, and lasting satisfaction for homeowners.
