Hupeyna 2.2lbs Waterproof Patch & Seal Paste - Clear, Invisible Indoor/Outdoor Repair

Hupeyna’s 2.2lbs Waterproof Patch & Seal Paste delivers a clear, rubberized seal that remains flexible as it cures. It adheres to a wide range of surfaces—from wood and tile to stone, roofs, and walls—creating a dense, impermeable layer that helps block air, water, and moisture without altering the surface texture.

What makes this paste stand out

• Sticky, pliable, water-based formula that cures into a dense rubberized coating
• Invisible finish that can be painted over to match décor
• Low-temperature and heat resistance for year-round use

Designed for practical, invisible waterproofing, the paste works on both dry and damp surfaces at the plug-and-seal stage. It dries to a smooth, paint-ready finish that preserves surface appearance while providing protective waterproofing.

How coverage and layering work

• Large capacity repairs larger areas: roughly 32-54 sq ft (3-5 sq m) per 1 kg
• Apply in thin layers, typically 1–2 coats for a durable seal

For best results, apply to clean surfaces. The paste is versatile for indoor and outdoor use on curved and vertical surfaces, including concrete, stone, tile, brick, wood, and glass. Once cured, it remains flexible and forms a protective barrier against leaks and moisture, while still allowing surface refinishing or painting.

Usage tips and conditions

• Temperature guideline: use at 10°C/50°F or higher; drier, sunnier days help cure faster
• Suitable for roofs, skylights, pipes, windows, basements, sheds, and other DIY repairs

Note that extended rain or very cold conditions can slow curing. Over time, the coating stabilizes and adheres more strongly. After it dries, you can paint or finish the surface to blend with surrounding areas, maintaining aesthetics while protecting against future leaks.
