Hydra Waterproof Sealant – Black | Instant Leak Repair & Long-Lasting Protection

Liquid Waterproof Sealant – Multi-Surface Leak Repair (300g, Black)

Premium Waterproofing Solution for Indoor & Outdoor Use

Stop leaks before they cause damage! Our Liquid Rubber Waterproof Sealant is a high-performance, industrial-grade coating designed to create a seamless, flexible, and long-lasting waterproof barrier on a variety of surfaces. Whether you're fixing a leaky roof, sealing a foundation, or protecting gutters, this bitumen-based formula provides superior adhesion and durability — even in extreme weather conditions.

Key Features & Benefits

✔ Industrial-Strength Bitumen Formula – Forms a thick, rubberized membrane that blocks water infiltration on flat roofs, metal roofs, concrete, wood, and more. A superior alternative to traditional roof tar or patch kits.

✔ Unmatched Flexibility (950% Elongation!) – Expands and contracts with temperature changes and building movement, preventing cracks and peeling. UV-resistant for long-term outdoor protection.

✔ Water-Based & Eco-Friendly – Unlike harsh solvent-based sealants, our low-VOC, odor-free formula is safe for indoor and outdoor use and won’t damage foam insulation or sensitive materials.

✔ Easy Application – Apply with a brush, roller, or sprayer for fast, mess-free waterproofing. Dries to a tough, rubber-like finish that withstands standing water.

✔ Professional-Grade Coverage

• Flat roofs / standing water surfaces: 1 gallon covers 15 sq ft (3-4 coats for 60-80 mil thickness).
• Vertical surfaces (foundations, walls): 1 gallon covers 30 sq ft (2-3 coats for 30 mil thickness).

✔ Multi-Surface Adhesion – Bonds strongly to metal, concrete, wood, PVC, and more. Not recommended for high foot traffic areas (patios, walkways, decks).

✔ Complete Waterproofing System – For maximum protection, pair with Liquid Rubber Seam Tape or Geo-Textile Fabric to reinforce joints, seams, and protrusions.

Ideal Applications

• Roof Repairs (flat roofs, low-slope roofs, metal roofs)
• Foundation & Basement Waterproofing
• Gutters, Downspouts & Flashings
• Planter Boxes & Concrete Surfaces
