Tufinein Rubber Sealant 53oz White – Quick-Dry Multi-Surface Waterproof Foundation

Overview

Tufinein’s Rubber Sealant 53oz (1.5 kg) White delivers a fast-drying, flexible foundation coating designed for indoor and outdoor use. The formula creates a rubbery film that moves with substrates, helping to block leaks while remaining easy to rework if needed. A typical film begins to form within a few hours, setting the stage for durable weather protection without lengthy downtime.

Whether you’re sealing a roof, gutter, basement wall, or exterior surface, this multi-surface foundation sealant aims to provide a resilient, water-repellent layer that adapts to changing temperatures and humidity. Remember that while it offers strong adhesion and flexibility, it’s not intended for use as a walking surface once cured.

Key benefits

• Elastic and durable: forms a flexible coating that tolerates minor substrate movement without cracking over time.
• Weather-ready performance: designed to stay stable across a wide temperature range, from -40 °C to 80 °C, helping resist aging on exterior and interior areas.
• Multi-surface adhesion: adheres to metal, concrete, wood, and many common substrates for versatile repairs.
• Quick-dry, self-leveling formula: applies by brush, roller, scraper, or pour and cures into a dense rubber membrane.

Typical applications

• Roofs, gutters, sheds, and concrete basements
• Walls, wooden skylights, planters, small water features like fountains or bird baths
• Indoor and outdoor projects that benefit from a flexible waterproof layer
• Joints and obvious cracks may benefit from polyester fabric reinforcement for enhanced seam protection

Usage and performance

• Vertical concrete foundations: 0.6 mm thick can cover about 2 m² (21.4 ft²).
• Flat or low-slope roofs and standing water areas: 1 mm thick covers about 1 m² (10.7 ft²).
• Self-leveling behavior allows smooth, continuous coverage with a brush, roller, scraper, or direct pour.
• Initial film forms in 2–4 hours; full curing depends on ambient conditions such as temperature and humidity.

Application tips

• Prepare surfaces by cleaning and drying to improve adhesion.
• Apply evenly with your preferred tool; for obvious cracks, layer on polyester fabric at joints.
• Follow with the recommended thickness for best coverage and performance; avoid applying on walking surfaces when cured.
