Overview
SENVEN Waterproof Sealant is a black liquid rubber coating for indoor and outdoor waterproofing projects. It uses a water-based, industrial-strength bitumen formula that creates a seamless waterproof membrane.
The coating is designed to form a durable barrier against water infiltration. Also, its flexible rubberized finish supports roof repair and preventative maintenance applications.
Key takeaways
- The formula creates a seamless waterproof membrane across suitable building surfaces.
- Its water-based composition contains no VOCs or harmful odors.
- You can apply the liquid coating with a brush, roller, or spray equipment.
- The coating features over 950% elongation for building movement and temperature changes.
- It supports flat roofs, foundations, gutters, concrete, planter boxes, walls, bathrooms, kitchens, and gardens.
- Rubber seam tape or geo-textile can bridge joints, seams, vents, skylights, and protrusions.
What the product is designed to do
This black waterproof sealant creates a seamless membrane on flat roofs, metal roofs, and low-slope roofs. Also, it covers foundations, gutters, concrete surfaces, planter boxes, and other building areas.
The coating forms a durable barrier against water infiltration where other sealants fail. In addition, it supports roof repair and preventative maintenance applications.
Indoor and outdoor uses include walls, bathrooms, kitchens, and gardens. For maximum protection, rubber seam tape or geo-textile can bridge areas where movement may occur.
Materials, dimensions, and technical details
The formula uses liquid rubber and a water-based bitumen composition. Also, the Black-35 Oz format comes in liquid form with a waterproof resistance level.

Installation and placement notes
You can apply this liquid rubber waterproof coating by brush, roller, or spray. Also, placement options cover horizontal, standing-water, low-slope, and vertical surfaces.
For flat or low-slope roofs and standing-water surfaces, one gallon covers 15 square feet. Apply three to four heavy coats to create a 60–80 mil membrane.
For vertical surfaces such as foundations, one gallon covers 30 square feet. Next, apply two to three heavy coats for a 30 mil membrane.
Joints and seams may require rubber seam tape or geo-textile for maximum protection. In addition, these materials can bridge vents, skylights, protrusions, and areas where movement may occur.
Performance characteristics described
The coating features over 950% elongation and maintains adhesion during building movement and temperature changes. Also, its flexible rubberized coating resists cracking, peeling, and UV damage.
The water-based advanced formula contains no VOCs or harmful odors. As a result, it supports indoor and outdoor waterproofing applications.
Premium adhesion technology supports most building materials, including metal, concrete, and wood. The water-based waterproof sealant also works without damaging foam insulation or sensitive materials.
The membrane forms a durable barrier against water infiltration. In addition, the coating supports leak repair and preventative maintenance across the named surfaces.
Review patterns buyers commonly mention
Buyers commonly report easy application with a brush or roller. Also, repeated feedback covers a thick black coating that spreads smoothly.
Drying-time experiences vary between quick drying and longer drying. However, durability feedback includes both resistance to water and weather and concerns about continued durability.
Leak-prevention experiences also vary. Some feedback covers stopped leaks, while other feedback covers continuing leak issues.
Pros
- The liquid format supports brush, roller, or spray application.
- The formula contains no VOCs or harmful odors.
- Over 950% elongation supports movement and temperature changes.
- The coating adheres to metal, concrete, wood, and other building materials.
- Repeated buyer feedback covers straightforward brush or roller application.
Cons
- Buyer experiences with drying time include both quick and longer drying.
- Durability feedback varies across water and weather exposure.
- Leak-prevention feedback includes both stopped leaks and continuing issues.
- Maximum protection around joints and protrusions uses seam tape or geo-textile.
- Coverage guidance calls for multiple heavy coats to reach the specified membrane thickness.
FAQ
Which surfaces support this waterproof coating?
The coating supports flat roofs, metal roofs, low-slope roofs, foundations, gutters, concrete, planter boxes, and other building surfaces. Also, indoor and outdoor uses include walls, bathrooms, kitchens, and gardens.
How do you apply the coating?
You can apply the coating with a brush, roller, or spray. The leak repair coating uses different coverage guidance for horizontal and vertical surfaces.
How much area does one gallon cover?
One gallon covers 15 square feet on flat roofs, low-slope roofs, and standing-water surfaces. For vertical surfaces such as foundations, one gallon covers 30 square feet.
How many coats does the application use?
Flat and low-slope surfaces use three to four heavy coats for a 60–80 mil membrane. Vertical surfaces use two to three heavy coats for a 30 mil membrane.
What flexibility does the coating feature?
The coating features over 950% elongation. Also, it maintains adhesion with building movement and temperature changes.
How should joints and seams be handled?
Rubber seam tape or geo-textile can bridge joints, seams, vents, skylights, and protrusions. This combination supports maximum protection where movement may occur.
