MasonryDefender Patio Paver Sealer
This water-based sealer dries clear with a low gloss, designed to protect pavers and stone while preserving color. It also hardens and stabilizes joint sand to help deter weeds and ants—helpful for outdoor patios and walkways. The product is VOC-compliant and formulated to prevent yellowing, making it a sensible pick for natural-toned patios where color retention matters. Best for homeowners seeking a clear finish with joint sand stabilization.
Who it’s best for: Outdoor homeowners needing a clear, low-gloss finish plus joint-sand stabilization in one coat. Limitations: As a water-based sealant, it may require reapplication over time in high-traffic or harsh environments.
SB-1300 G Natural Look Matte Finish JSS
SB-1300 G is a breathable, water-based acrylic co-polymer sealer that preserves and protects the natural tone of surfaces while binding joint sand to reduce sand loss. It provides a colorless, matte finish, ideal for pavers where a natural look is preferred and subtle protection is required. Best for projects prioritizing natural aesthetics with sand-binding benefits.
Who it’s best for: Those who want a colorless, matte finish that keeps natural tones intact and minimizes sand loss. Limitations: Matte finishes can show wear sooner than high-gloss options in some climates; expect periodic reapplication to maintain look and protection.
DOMINATOR Polymeric Sand with Ceramic Flex
Dominators’s polymeric sand uses Ceramic Flex technology to provide flexible, durable joint stabilization from 1/8” up to 4”. It’s designed to ease installation with a new Easy Pour Handle for portability and precise application. The product helps lock joints and reduce weed growth while delivering a visually clean joint line. Best for professional projects seeking robust joint performance and faster installation.
Who it’s best for: Contractors and serious DIYers needing strong, flexible joints with straightforward handling. Limitations: Not a replacement for grout or edging; use as a joint filler in appropriate beds.
Siloxa-Tek 8500 Ready to Use
Siloxa-Tek 8500 is a penetrating silane/siloxane sealant that reduces water and moisture intrusion without altering aesthetics. It is breathable, low-VOC, and DOT-approved, offering long-lasting protection against chloride damage, freeze-thaw cycles, and salt exposure. This product is ideal for those who want to maintain the natural look of concrete, brick, masonry, and pavers while protecting against water-related damage.
Who it’s best for: Surfaces exposed to weather extremes where breathability and long-term water repellency matter. Limitations: Penetrating sealers may not produce a visible surface sheen; expect a natural look rather than a glossy finish.
Premium Stone Sealer, Max Gloss Wet Look
This product delivers a high-gloss, wet-look finish designed to dramatically enhance color vibrancy. It provides waterproofing and UV resistance, filtering out most UV rays to protect against fading. It works well on natural stone, concrete, and masonry surfaces where a luxurious, eye-catching finish is desired. Note that it is not suitable for polished stone or tile.
Who it’s best for: Projects where a dramatic, glossy finish adds visual impact to stone surfaces. Limitations: Not suitable for polished stone or tile; high gloss may show wear in high-traffic areas over time.
Buying Guide
Key considerations when choosing a joint sealer for pavers:
- Choose between clear low-gloss, colorless matte, or high-gloss wet look. Clear sealers preserve original color; matte sealers minimize sheen; gloss sealers maximize color and impact.
- If preventing weed growth and sand loss is a priority, select products with joint sand hardening or binding properties. Some sealers also act to lock sand in place.
- For climates with freeze-thaw cycles, breathable penetrating sealers reduce moisture intrusion and mitigate cracking. Non-film-forming formulas tend to be more durable over time.
- Look for user-friendly packaging, pour handles, or spray/roller/brush compatibility. Consider whether one-step products meet your project’s needs or if multi-step solutions are required.
- Confirm that the sealer works with your surface type—pavers, brick, natural stone, or concrete—and whether polished finishes are recommended or discouraged.
- Check VOC content and regulatory approvals (e.g., DOT) when selecting products for outdoor installations or spaces with exposure concerns.
Frequently Asked Questions
- Do joint sealers prevent weed growth? Some sealers stabilize joint sand to reduce weed growth and sand loss, though aggressive weed growth may require additional landscaping controls.
- Can I apply a gloss sealer over a matte one? It is better to apply a product designed for the desired finish; applying multiple coats of different finishes can yield uneven aesthetics and performance.
- Will sealers change the color of my pavers? Many clear or colorless sealers preserve the natural look; some products add a tint or glossy finish that enhances color.
- How often should I reapply sealer? Reapplication depends on climate, traffic, sun exposure, and product type. Penetrating sealers may last longer between applications than surface-level coatings.
- Is a solvent-based sealer better than a water-based sealer? Water-based formulas tend to have lower VOCs and easier cleanup; solvent-based sealers can deepen color and sheen but may require more ventilation during application.
- Can I seal over existing sealant? In many cases, you should remove or rejuvenate existing sealers before applying a new coat to achieve proper adhesion and performance.
