Tufinein Rubber Liquid Waterproof Coating — 53oz/1.5kg Black, Quick-Dry Multi-Surface Sealant

Overview

Tufinein Rubber Liquid Waterproof Coating is a modern, single-component, moisture-curing elastic coating. When exposed to atmospheric moisture, it forms a durable flexible rubber membrane that protects roofs, gutters, basements, walls, and other substrates. This coating is designed for long-term performance across a range of climates and surfaces, helping you build a reliable water barrier without complicated steps.

Key advantages include strong adhesion, good self-leveling behavior, and a balance of toughness with elongated stretch. The film resists cracking as the substrate moves, and it stands up to wind and rain, offering a practical solution for multi-surface waterproofing tasks both indoors and outdoors.

Why it matters

The coating delivers a water-repellent layer that remains effective even when submerged in low-pressure water environments over time. Its operating window after curing spans extreme temperatures, supporting reliability in cold winters and hot summers. It can be applied in winter when conditions are above freezing, expanding your project windows.

How it goes on and how it performs

• ELASTICITY & EXTENSIBILITY: Easily bridges small gaps, self-levels, and dries to a flexible rubber finish that shields surfaces from moisture.
• LONG-LASTING WEATHER RESISTANCE: Maintains stability across a wide temperature range and adheres well to multiple substrates, resisting aging and cracking.
• ROOF SEALANT USE: Suitable for metal roofs, basements, walls, gutters, skylights, and even planters or small water features; note it is not intended for walking surfaces once cured due to tackiness.
• MAXIMUM COVERAGE & JOINTS: Vertical concrete surfaces at 0.6 mm deliver about 2 m² coverage; flat or low-slope roofs at 1 mm cover about 1 m²; reinforce obvious joints with fabric for enhanced waterproofing.
• FLEXIBLE SEALANT: Self-leveling and usable with brush, roller, scraper, or pour method, forming a dense, water- and moisture-blocking membrane.

Practical uses

• Foundations, basements, and concrete walls that require a moisture barrier.
• Gutters, roof edges, skylights, and exterior woodwork needing reliable sealing.
• Outdoor planters, small water features, and other low-pressure water exposure areas.
• Indoor-outdoor installations where a flexible, durable membrane can reduce leaks without heavy coating schedules.

Notes for best results

Prepare surfaces as advised for the substrate, and follow temperature guidelines. Although winter application is possible above -10°C, plan around ambient conditions to achieve even film formation and optimal adhesion.
