Transparent Waterproof Coating 70oz Clear Sealant - Invisible

In this review of the Transparent Waterproof Coating 70oz, the bottom line is simple: this clear, water-based sealant is best for homeowners and DIYers who need an invisible, long-lasting barrier against leaks on porous surfaces. The reviewer found the product easy to apply and effective at stopping surface water penetration, especially on concrete and masonry. Curing to a crystal-clear, non-yellowing membrane, it preserves the look of materials while providing a flexible, durable film that improves with time and resists both heat and low temperatures.

Key Features

• Invisible Waterproofing: The water-based formula cures to an invisible membrane that protects against air, water, and moisture without changing surface appearance.
• Clear & Non-Yellowing: A crystal-clear finish keeps natural textures and colors intact, allowing multi-layer builds without clouding.
• Flexible Film-Forming: The self-leveling liquid penetrates small gaps and forms a resilient, flexible barrier that adapts to minor substrate movement.
• Strong Adhesion: Polyurethane-based adhesion reduces sagging and ensures deep penetration into porous materials for longer-lasting protection.
• Versatile Use: Suitable for concrete, brick, metal, wood, roofs, walls, gutters, basements, and many indoor and outdoor surfaces for broad utility.
• Coverage & Layering: A 70 oz (2 kg) container covers about 28 sq ft and supports 2-3 layers for complete waterproofing in most small repair jobs.

Who It's For

This clear waterproof sealant is ideal for homeowners repairing roof edges, window sills, small flat roofs, patios, garden planters, and concrete steps where appearance matters. It is also useful for contractors doing small-scale repairs who want a non-visible finish that blends with existing materials.

It is less suitable for very large commercial roofs where bulk coverage logistics or specialized spray equipment are required, or for applications that demand a colored or textured finish. Very cold environments below 10C/50F will slow curing, so users in those climates should plan around warmer conditions.

Pros & Cons

Pros

• Easy to apply and praised by customers for its user-friendly nature and effective waterproofing.
• Crystal-clear, non-yellowing result preserves the look of surfaces while adding protection.
• Good adhesion and flexibility reduce the chance of cracking when substrates shift.
• Covers about 28 sq ft per 70 oz and allows multi-layer builds for thorough sealing.

Cons

• Curing is temperature dependent and slows below 10C/50F, which can delay projects in cool weather.
• For very large areas, multiple containers or professional spray systems may be more economical.
