The Liquid Rubber Basement and Foundation Repair Sealant is designed primarily for waterproofing and crack filling in concrete structures. One of its standout features is its flexibility, boasting a 900% elongation which helps prevent future cracks and damage. This makes it highly durable for both indoor and outdoor use.

Its tackiness once cured means it's more suited for walls and foundations rather than floors. The product's water-based formula is safe for indoor use and emits zero VOCs, which is beneficial for health and environmental safety. The application is straightforward, requiring no mixing and can be done with a brush, roller, or sprayer.

It also offers versatility by adhering well to various materials such as concrete, masonry, wood, and metal. In terms of coverage, it's efficient though it requires multiple coats for optimal results, which can be seen as a drawback in terms of time and effort required for application. It excels in providing a watertight seal when used with Liquid Rubber Geo-Textile on joints and transitions.

The Armor AR350 Low Gloss Wet Look Concrete Sealer is a professional-grade product designed to protect and enhance exterior concrete and pavers. One of its standout features is the dramatic color enhancement it provides, making surfaces look as they do when wet. This sealer offers long-lasting protection against surface abrasion, UV rays, water absorption, and harsh weather, making it highly durable. It is suitable for various applications including driveways, patios, walkways, and pool decks.

The product's low gloss finish adds a subtle sheen without being overly shiny, which many users might appreciate. The sealer is ready to use and can be applied with a roller or sprayer, making the application process straightforward. It covers up to 175-225 square feet per gallon, which is efficient for large areas. Additionally, it is easy to maintain and only requires a single coat for resealing, simplifying upkeep.

However, being solvent-based, it may not be as breathable as water-based alternatives, potentially trapping moisture if not applied correctly. The drying time is not specified but is generally quick for solvent-based sealers. The product is available in different VOC formulations to comply with regulations in all 50 states, which is a plus for versatility but means users need to choose the appropriate version for their state. While its performance and ease of use are impressive, the 42-pound weight and solvent-based nature might be considerations for some users.

The Armor SX5000 WB Natural-Look Penetrating Water-Based Silane Siloxane Concrete Sealer is a professional-grade product designed for various surfaces such as concrete, brick, pavers, and natural stone. Its primary strength lies in its ability to significantly reduce water absorption, providing up to 95% resistance, which is beneficial for minimizing damage caused by water, ice, salt, and organic growth. This sealer forms a durable, water-repellent barrier that can last between 7 to 10 years, making it a long-lasting solution.

Moreover, it maintains the original look and feel of the substrate, which is ideal if you prefer the natural appearance of your surfaces without any glossy finish. The water-based formula is environmentally friendly with 0 VOC and no odor, simplifying cleanup with soap and water. Applying the sealer is straightforward with a pump sprayer, and maintenance is easy since it works below the surface without forming any film or coating.

However, the sealer's minimal gloss level might not appeal to those seeking a high-shine finish. Additionally, while it provides excellent UV resistance and breathability, ensuring the surface preparation is proper and dry before application is crucial for optimal performance. Weighing 44 pounds and compact in style, this product is ready-to-use but may require effort in handling and storage. Users looking for a durable, non-glossy, and easy-to-apply concrete sealer with long-lasting protection will find the Armor SX5000 WB to be a suitable choice.
