McKinnon Concrete & Paver Sealer 5 Gallon
This professional-grade, penetrating sealer is designed for concrete, pavers, brick, and natural stone. It provides a semi-gloss wet look that enhances color without creating a heavy topical film. Suitable for both outdoor surfaces and interior hardscapes that endure foot traffic.
- Best for: Driveways, patios, pool decks, walkways, and garage floors where a natural-saturated finish is desired.
- Why selected: Combines UV resistance with deep color enhancement, offering durable protection while preserving the natural character of the substrate.
Caution: As a penetrating sealer, surface preparation and clean, dry substrates are important for consistent results. Test a small area before full application.
Cryli-Tek 5505 Gallons
This solvent-based acrylic sealer delivers a high-gloss, wet look for concrete and pavers. It also provides water repellency, helping protect against moisture intrusion. Best for projects needing a dramatic, glossy finish with added moisture resistance.
- Best for: Surfaces where a strong, reflective gloss is desired, such as decorative driveways and patios.
- Why selected: Combines high-gloss aesthetics with water repellence to maintain the appearance longer under sun exposure.
Caution: Solvent-based coatings may require good ventilation and follow-up maintenance to sustain gloss over time. Test on a small area first.
Lithi-Tek 9500 Ultra Concentrate
This water-based penetrating sealer densifies, strengthens, and waterproofs concrete. It reduces moisture and vapor transmission and helps prevent efflorescence, improving long-term durability and abrasion resistance.
- Best for: New or aged concrete surfaces where deep penetration and densification are desired to improve wear resistance.
- Why selected: A penetrating formula that enhances the substrate rather than just coating the surface, supporting structural longevity.
Caution: Requires proper ventilation during use and multiple coats may be needed for optimal penetration on very dense mixes.
QuestMark 2105 Epoxy Patch
This epoxy-based patch and resurfacer is designed to fill cracks, holes, pits, and spalling on 5-gallon units. It prepares a strong, smooth surface ready for coatings and refinishing. Best for repairs before finishing with paint or sealer.
- Best for: Repairing damaged concrete prior to applying a sealer or paint coating.
- Why selected: Provides a solid substrate, reducing later coating failure due to substrate irregularities.
Caution: Not a substitute for structural repair; follow product instructions for curing times and surface prep.
KILZ 1-Part Epoxy Concrete & Garage Floor Paint
This epoxy paint provides durable protection for concrete floors with a satin finish. It resists hot tire pickup, scuffing, cracking, peeling, and fading, making it suitable for indoor and outdoor horizontal surfaces.
- Best for: Basements, garages, porches, driveways, and pool decks needing a strong, uniform color.
- Why selected: Combines practical durability with a versatile interior/exterior footprint and easy application.
Caution: Not recommended for vertical surfaces or areas with hydrostatic pressure or forklift traffic.
Buying Guide
What should I consider when choosing concrete floor paint or sealer?
Material type matters. Penetrating sealers protect by strengthening the substrate, while film-forming coatings create a protective layer with a visible gloss. Choose based on whether you want to preserve texture and color depth (penetrating) or a strong, glossy finish (film-forming).
Indoor vs. outdoor suitability
Outdoor surfaces require UV resistance and weatherproofing against rain and freeze-thaw cycles. Indoor surfaces benefit from low odor and easy cleanability. Consider air quality, ventilation, and foot or vehicle traffic in the area.
Gloss level and aesthetics
Semi-gloss and high-gloss finishes offer rich color and a reflective look, while matte finishes hide surface imperfections. Balanced choices deliver both aesthetics and durability for concrete floors in living spaces, garages, and patios.
Durability and maintenance
Film-forming coatings may require periodic reapplication to maintain gloss, while penetrating sealers emphasize longevity with minimal surface build-up. For high-traffic areas, look for abrasion resistance and moisture protection.
Surface preparation
Clean, dry, and properly cured concrete yields the best adhesion. Repair any cracks or holes before sealing or painting. For epoxy-based paints, ensure the substrate is sound and properly primed if needed.
Application considerations
Follow the manufacturer’s guidelines for mixing, curing times, ventilation, and cleanup. Test a small area to confirm color, penetration, and film formation before full-scale application.

Frequently Asked Questions
- What is the difference between penetrating sealers and epoxy paints? Penetrating sealers soak into concrete to strengthen and repel moisture, preserving texture. Epoxy paints form a durable film on the surface for a colored, protective coating.
- Can I apply sealer over an existing painted floor? It depends on the existing coating. In many cases, a clean, dry surface is required and a compatible topcoat may be necessary. Always test a small area first.
- How long should I wait before walking on a sealed floor? Curing times vary by product; follow the manufacturer’s guidance. Plan for at least 24-48 hours for light foot traffic, longer for heavy use.
- Is UV exposure a concern for sealers? Yes. Outdoor surfaces should use UV-resistant formulas to prevent color fading and material degradation over time.
- Are these products safe for indoor air quality? Opt for water-based formulas when possible to minimize VOCs and odors, especially in garages and basements with limited ventilation.
