Hupeyna Liquid Waterproof Sealant – Transparent, Invisible Coating for Indoor & Outdoor Use (35 oz)

Overview

Hupeyna Liquid Waterproof Sealant delivers an invisible, flexible protective coating that blocks air, water and moisture from seeping through cracks. This water-based formula bonds to a variety of surfaces and forms a clear film you can leave as is, preserving surface appearance while adding a layer of protection against the elements.

Why this sealant stands out

• Invisible protection that seals cracks and gaps without altering the surface look
• Self-leveling and easy to apply with brush, roller or pour methods
• Weather-ready performance with compatibility for indoor and outdoor use
• Long-lasting film that helps reduce maintenance over time

How to use

Mix thoroughly before use. Apply with a brush to soak and wipe, a roller for broad areas, or pour and spread for hard-to-reach joints. The formulation self-levels to cover small gaps evenly and forms a continuous sealing layer.

• Apply in 3 to 4 thick coats for best results
• One kilogram covers about 14 square feet when coats are applied thick
• Let each coat dry in a dry, sunny environment between applications

Where to use

Suitable for flat and sloped roofs, external walls, foundations, sheds, basements, metal and wood surfaces, concrete, gutters, skylights, chimneys, PVC pipe joints, windows, RVs and DIY projects. It also seals external pipe joints and surface gaps around substrates.

Weather and curing tips

Prolonged rain or very cold conditions can slow curing. For best results, ensure a sunny, relatively dry environment and maintain temperatures of at least 10 C (50 F) during application and drying.

Limitations

Not intended for long term water storage or areas with continuous water pressure such as swimming pools.

What you get

The transparent repairing sealant forms a long-term protective film that helps shield surfaces from moisture and air intrusion while preserving the surface appearance.
