Wet Look Stone Sealer By Black Diamond
Black Diamond Stoneworks Wet Look Sealer delivers a high-gloss finish that enhances the depth and richness of decorative stone and concrete. It is suitable for exposed aggregate, stamped, colored, or other decorative surfaces, indoors or outdoors. The sealer magnifies color while preserving the stone’s natural feel after it dries, making it a popular choice for driveways, patios, and exterior pavers. Application is flexible, with spray, brush, or roller options to accommodate large slabs or tight corners. It resists chemicals and delivers robust protection against stains and weathering without overly darkening most surfaces.
Two key advantages are its versatility and its natural-appearing finish. The product enhances textures such as slate, brick, and concrete while maintaining a relatively natural look once cured. It forms a protective barrier that helps repel moisture and chemical intrusion, making it suitable for regions with freeze-thaw cycles or chemical exposure from cleaners or automotive fluids. For best results, clean the surface first and apply evenly in thin coats, allowing adequate drying between passes.
- Glossy wet-look finish that enhances texture
- Versatile: spray, brush, or roller application
- Preserves natural appearance after drying
Nanoprotect Cement & Stone Sealer
Nanoprotect Cement & Stone Sealer provides invisible impregnation on absorbent mineral substrates, creating a beading effect against water and dirt while offering frost protection. The sealer is marketed as a long-lasting solution, incorporating a two-phase action: deep bonding with mineral components for substantial moisture resistance, followed by a surface-beading layer that guards against staining. It is versatile across driveways, patios, balconies, walkways, and facades, and works on marble, concrete, cement, tile, limestone, natural stone, quartzite, travertine, and sandstone. The result is a protected surface that remains breathable and aesthetically balanced.
The product emphasizes durability and beading performance, making it a practical choice for outdoor installations where long-term maintenance is desired. Because the impregnant penetrates the substrate, it minimizes surface alteration while delivering effective weatherproofing. For best results, apply to clean, dry surfaces and follow cure times and re-application guidelines included by the manufacturer.
- Invisible impregnation with beading action
- Two-phase action for deep bonding and surface protection
- Suitable for a wide range of porous surfaces
MasonryDefender Brick Stone & Concrete Sealer
MasonryDefender All Purpose Brick Stone & Concrete Sealer offers a penetrating silane/siloxane shield that forms a clear barrier to outdoor masonry surfaces without altering their natural look.

It is designed for wide-ranging exterior applications, including patios, sidewalks, and driveways, with a practical coverage profile that makes it suitable for medium to large projects. The focus is on preserving the original appearance while providing durable moisture protection against weathering and freeze-thaw cycles.
The key advantage is a clear, penetrating protection that does not change color or sheen, making it ideal for those who want a low-profile finish. It also helps reduce efflorescence and can extend the life of outdoor masonry by limiting water ingress. For best results, ensure surfaces are clean, dry, and free of existing sealers before application. Reapply according to the product’s maintenance schedule to maintain protection levels.

Color Enhancer Sealer For Natural Stone
Black Diamond Stoneworks Color Enhancer Sealer is designed to revive and deepen color on natural stone and Pavers including marble, travertine, limestone, granite, slate, and concrete. It restores faded surfaces and delivers water-based protection that allows stone to breathe while improving tone and vibrancy. This sealer is well-suited for outdoor paths, patios, and entryways where color enhancement is desired without heavy gloss. It provides surface protection from water intrusion while maintaining a natural, breathable finish that is appropriate for porous stone and grout.
This product is especially useful for reviving weathered stone and restoring a fresh look to pavers and garden features. Because it is water-based, it tends to dry with less odor and faster cure times than solvent-based alternatives. Surface preparation—cleaning, drying, and mild scrubbing—ensures uniform color enhancement. Apply evenly and avoid pooling to prevent streaking on highly textured surfaces.
- Enhances natural color and depth
- Breathable, water-based protection
- Restores faded surfaces indoors or outdoors

Buying Guide
Choosing the right exterior stone sealer involves balancing surface type, appearance goals, and maintenance requirements. Here are key purchase considerations to guide your decision:
- Surface type and porosity: Porous stone and concrete absorb sealers differently. Quietly porous surfaces benefit from penetrating sealers, while decorative concrete or slate may suit film-forming or gloss-enhancing products for a visible finish.
- Penetrating vs film-forming: Penetrating sealers protect from within without changing color or sheen. Film-forming sealers create a surface gloss, enhancing color and texture but may require maintenance to prevent peeling.
- Gloss level and color enhancement: Decide whether you want a high-gloss wet look, a natural matte finish, or a color-enhancing effect that deepens tones without artificial sheen.
- Indoor vs outdoor exposure: Outdoor surfaces demand UV resistance, water beading, and freeze-thaw protection. Indoor applications may prioritize odor, VOC content, and breathability.
- Breathability and moisture management: Breathable sealers prevent moisture entrapment, reducing risk of cracking, efflorescence, and mold growth.
- Coverage and re-application: Check approximate coverage per gallon and recommended re-application intervals. Larger areas may benefit from bulk containers; smaller projects may prefer quarts for color-enhancing products.
- Safety and environmental considerations: Look for low-VOC formulas and non-toxic ingredients if the application area is near living spaces or gardens.
- Maintenance needs: Some sealers require surface cleaning and periodic reapplication to maintain protection; others offer long-lasting performance with minimal upkeep.
In selecting a sealer, consider your climate, foot traffic, and whether you value a glossy finish, enhanced color, or a low-profile protective layer. For historic or visually sensitive stones, a breathable, clear, penetrating sealant often offers the best balance of protection and authenticity. For high-traffic driveways or pool decks, a robust barrier against water and salts with minimal color change is typically preferred. Always follow manufacturer instructions for surface preparation, curing times, and re-application to maximize the sealer’s effectiveness over time.
