## Description

Product description Stops leaks fast. Starts out as a thick liquid and dries to a super strong, flexible, watertight, rubberized coating. Seeps into cracks and holes. Blocks out air, water, and moisture for a superior seal, virtually anywhere. Prevents rust and corrosion. Extends the life of patio furniture, pool pumps, RV and shed roofs, and more. Stands up to extreme weather changes. Expands, contracts, flexes and stretches. Resists rain, snow, sun, and hail. Exceptional adhesion. Works on all types of surfaces, even challenging ones, like metal and glass. UV and chemical resistant. Use indoors and outdoors for basement waterproofing, foundation fixes, roof repairs, and more. DIRECTIONS Fully clean and dry the surface for best results. Etch the surface to help with adhesion if needed. For the best application, use a standard disposable paint roller or paint brush. Apply several even, thin coats and wait 24 - 48 hours for each layer to fully dry before adding the next. Always place the lid back on the container after each use. If drying occurs, remove any skin before using product.

Review: Used for my Wide Driveway Cracks - You’ve seen the commercials. I used this to fill the 3/4” to 1.5” cracks in my asphalt driveway. I’ve used the Black Flex Seal Liquid for as long as ten years to fill the cracks. I never had any fail. I live in a harsh winter area. It’s expensive and you have to come up with your own system as to how to apply. I transfer from the big container to a Pyrex 16oz measuring cup.

### ⭐⭐⭐⭐⭐ Works like a charm!!
*by A***. on June 29, 2025*

I've had a leaky balcony issue for a long time that leaked through to my kitchen ceiling. I used a little can of flex seal for the bad spots and it worked so well that I bought the bigger container and did my entire balcony myself. Didn't leak through all of those bad rain storms we've had lately. This stuff is freaking amazing!!!!!
