Is Flex Paste Good for Concrete?
Concrete surfaces are tough—but they’re not indestructible. Over time, cracks, holes, and surface damage can allow water and moisture to seep in, leading to bigger problems down the line. That’s where Flex Paste® comes in.
This thick, rubberized paste is designed to cling to even the roughest surfaces, making it a solid choice for a wide range of concrete repairs.
Why Flex Paste Works on Concrete
Flex Paste is specially formulated to fill and seal cracks, gaps, and holes, creating a durable, waterproof barrier that stays strong and flexible over time. This super thick rubberized paste can help protect concrete from weather damage, erosion, and structural wear.
It's a great match for concrete because it:
· Bonds to rough, porous surfaces
· Fills deep cracks and damaged areas
· Seals out water, air, and moisture
· Remains flexible to help prevent future cracking
Ideal for use on concrete areas like:
· Foundation cracks
· Sidewalks and steps
· Basement walls
· Driveways and patios
· Around drains or posts embedded in concrete
Once applied, Flex Paste begins forming a skin within minutes, and once cured, it creates a tough, long-lasting seal that stands up to the elements.
Tips for Best Results
· Always clean the surface before applying
· Use a putty knife, gloved finger, or trowel to press Flex Paste into the crack or hole
· Shape and smooth within 10 minutes of application before it forms a skin
· Allow 24 to 48 hours for it to fully cure, depending on temperature and humidity
Flex Paste is a smart, effective choice for sealing and repairing concrete. Whether you're patching a small crack or filling a larger damaged area, it delivers a strong, waterproof seal that holds up over time. Looking for step-by-step instructions?
