Armor AR350 Low Gloss Wet Look 5 Gallon
Type: Solvent-based, low gloss wet look. Purpose: Exterior concrete and pavers; for unsealed surfaces or those previously sealed with a solvent-based acrylic. Benefits include dramatic color enhancement and a long-lasting, non-yellowing finish. Best for projects where a wet-look, darker appearance is desirable. Caution: Solvent-based sealers emit stronger odors and require good ventilation during application. Suitable for larger outdoor areas and commercial applications due to the 5-gallon size.
Armor AR350 Low Gloss Wet Look 1 Gallon
Type: Solvent-based, low gloss wet look. Purpose: Exterior concrete and pavers; good for unsealed or previously sealed surfaces needing color enhancement. Benefits mirror the 5-gallon version with easier handling. Best for smaller projects or touch-ups. Caution: Like other solvent-based products, ensure adequate ventilation and proper protective gear during application.
CC Concrete Coatings SuperSeal 20WB
Type: Water-based; finish: Satin. Purpose: Safer alternative to solvent sealers, suitable for many porous surfaces and indoor/outdoor use. Benefits include low odor, easier cleanup, and good chemical and stain resistance. Best for spaces where low VOCs are a priority and a non-gloss finish is preferred. Limitation: May require more coats for deeper color enhancement or longer protection than solvent-based options.
Rain Guard Concrete Sealer 1 Gallon
Type: Silane/siloxane waterproofer; finish: natural. Purpose: Deep penetration barrier against water and salt damage for all concrete surfaces. Benefits include easy application and quick drying, with visible water-beading indicating protection. Best for DIYers focusing on long-term substrate durability. Limitation: Silent on color change; does not provide a glossy or darkened look.
Wet Look Stone Sealer by YKF
Type: Water-based; finish: satin. Purpose: Outdoor stone surfaces, including pavers, concrete, slate, and driveways. Benefits include a rich wet-look finish that enhances color on rough textures. Best for large outdoor stone projects where a durable satin sheen is desired. Caution: May require more frequent maintenance in extreme weather or heavy traffic areas.
Buying Guide
What to consider when choosing a no VOC concrete sealer:
- Surface type and porosity: Pavers, concrete slabs, and stone have different sealing needs. Penetrating sealers work well for porous surfaces, while surface sealers provide a protective film.
- Finish preference: Wet look, satin, or low-gloss finishes affect appearance and maintenance. Your choice should align with aesthetic goals and traffic expectations.
- VOC level: No or low VOC sealers reduce odor and environmental impact. Solvent-based formulas often offer deeper color enhancement but require ventilation and precautions.
- Indoor vs outdoor use: Some sealers are optimized for indoor spaces with lower exposure to UV and weather, while others are built for exterior durability against chemicals, moisture, and freeze-thaw cycles.
- Application and cure time: Drying and recoating intervals affect project timelines. Water-based products typically cure faster and cleaner for DIY work.
- Maintenance and longevity: Longer intervals between re-sealing reduce total cost of ownership but may trade off with color depth or gloss level.
- Safety and cleanup: Water-based sealers offer easier cleanup and lower odor; solvent-based formulas may require specialized cleanup and safety gear.

FAQ
- What is a no VOC concrete sealer?
A no VOC or low VOC sealer minimizes volatile organic compounds during application, reducing odor and environmental impact while protecting the concrete surface.
- Can I use a water-based sealer on exterior surfaces?
Yes, many water-based sealers are suitable for exterior use, offering safer application with good protection, though they may require additional coats for deeper color or longer protection.
- Will sealer darken or alter the color of my concrete?
Some sealers, especially solvent-based wet-look types, darken surfaces and give a wet appearance. Water-based options typically offer a milder color change or satin finish.
- How long does a no VOC sealer typically last?
Durability varies by product and conditions, but many sealers provide protection for several years, with longer life in low-traffic areas and proper maintenance.
- Is professional application required for solvent-based sealers?
Professional application is not always required, but solvent-based sealers demand proper ventilation, masking, and safety gear during use.
- Should I seal indoor concrete as well?
Yes, indoor sealing reduces staining and water absorption and can improve surface longevity, especially in garages and basements with higher exposure to spills.
