Note: All products listed are penetrating, water-based or solvent-based sealers that aim to preserve appearance while enhancing durability. For fountain installations, consider color retention, breathability, and resistance to salt or chlorides from deicers used nearby.
Siloxa-Tek 8500 Ready to Use
Siloxa-Tek 8500 is a water-based silane/siloxane penetrating sealer designed to minimize water and moisture intrusion in concrete, brick, masonry, and pavers. It leaves a natural look with no film formation, preventing peel, flake, or delamination. The DOT-approved formula provides resistance to surface damage from chlorides and deicing salts, making it suitable for fountain components exposed to runoff or winter treatment chemicals. Its six times higher actives concentration compared to many water-based sealers offers long-lasting protection against wind-driven rain and freeze-thaw cycles. The breathable formula helps maintain substrate integrity while preserving aesthetics.
Key features: water-based, penetrating, breathable; creates a protective barrier without changing color; DOT approved; high actives for extended protection; resists chlorides and deicing salts; suitable for concrete, brick, masonry, and pavers. For fountains, this sealer helps guard against moisture-related damage while maintaining the fountain’s natural appearance.
McKinnon Concrete Sealer (5 Gallon)
McKinnon Concrete Sealer is an industrial-grade, water-based acrylic sealer formulated for both outdoor and indoor applications. It works on unsealed or previously sealed concrete, pavers, stone, brick, and related surfaces. The formula is designed to resist peeling or cracking, offering durability for fountain bases and surrounding features. It provides versatility across substrates commonly found around water features, helping to maintain appearance while delivering protective performance.
Key features: industrial-grade, water-based; suitable for unsealed and previously sealed surfaces; resists peeling and cracking; versatile on concrete, pavers, stone, brick, and stucco; ideal for both outdoor and indoor use in fountain surroundings.
Armor SX5000 WB Natural-Look
Armor SX5000 WB Natural-Look is a professional-grade silane/siloxane sealer designed for concrete, brick, pavers, and natural stone. This water-based formula reacts chemically to form a water-repellent barrier beneath the surface, significantly reducing water absorption by up to 95%. It is formulated to protect without altering color or appearance, preserving the fountain’s natural look. Suitable for unsealed or previously sealed substrates, it helps guard against freeze-thaw damage, salts, and spills common near water features.
Key features: professional-grade silane/siloxane; reduces water absorption up to 95%; color-neutral and non-yellowing; suitable for multiple substrates; maintains natural look while protecting against moisture and salts.
MasonryDefender Concrete Sealer
MasonryDefender Concrete Sealer provides clear, penetrating protection that does not alter the color or appearance of concrete, making it well-suited for fountains where aesthetics matter. It bonds with concrete and masonry to form a durable water-repellent layer, helping to bead and roll off moisture while allowing the surface to breathe. This makes it effective against pitting, cracking, and damage from ice melt salts, chlorides, and freeze-thaw cycles. It supports longevity for driveways, patios, and water-feature components exposed to the elements.
Key features: clear, penetrating sealer; water-repellent with surface breathability; protects against salts and freeze-thaw; suitable for concrete, masonry, and patios; preserves natural appearance.
Lithi-Tek 9500 Ultra Concentrate
Lithi-Tek 9500 Ultra Concentrate is an industrial-grade sealer that densifies, strengthens, and waterproofs concrete. When used as a concentrate, it extends up to five gallons of finished sealer, providing a cost-efficient solution for fountain projects. The formula reduces moisture and vapor intrusion, helps prevent efflorescence, and lowers hydrostatic pressure. It also serves as a durable waterproofer that minimizes moisture-related damage and ASR (alkali-silica reaction). For fountains with thick or porous concrete, this product delivers deep penetration and long-term protection.
Key features: densifier and sealer; extends coverage when diluted as a concentrate; reduces moisture intrusion; prevents efflorescence and ASR; deep penetration for durable protection.
Buying Guide: Key Considerations For Choosing A Fountain Sealer
- Breathability: Choose a penetrating, breathable sealer to prevent moisture buildup inside concrete while maintaining aesthetic integrity of the fountain finish.
- Water Repellency: Look for high water absorption reduction (often measured as a percentage) to resist rain, irrigation splashes, and deicing salts around the fountain area.
- Color Impact: For fountains, color neutrality is important. Opt for sealed products that clearly state “colorless,” “natural look,” or “won’t change the color.”
- Film Formation: Avoid film-forming sealers that can peel or delaminate due to temperature changes or water exposure; prefer penetrating formulas.
- Substrate Compatibility: Confirm compatibility with concrete, pavers, brick, natural stone, and stucco if your fountain uses multiple materials.
- Durability vs. Maintenance: Balance long-lasting protection with maintenance cycles. Some products offer stronger resistance to salts and freeze-thaw, reducing maintenance needs.
- VOC Content and Safety: For outdoor fountain installations, consider low-VOC or zero-VOC options for better air quality and easier compliance with local regulations.
- Application Conditions: Check surface preparation needs, cure times, and number of coats. Some sealers require dry weather and specific temperatures for best results.
- Cost and Coverage: Compare coverage rates per gallon and whether the product is sold in convenient sizes for fountain dimensions. Concentrates can be economical for large volumes.
Selecting the right sealer involves assessing the fountain’s materials, exposure to weather and deicers, and the desired appearance. Penetrating, breathable sealers with strong water-repellency and minimal color change are generally best for maintaining the look of concrete fountains while extending their lifespan.
