Frequently Asked Questions
Q: What surfaces can I use this concrete crack filler sealant on?
A: This waterproof sealant is designed for use on a wide range of surfaces including concrete walls, roofs, driveways, ground surfaces, basements, and underground facilities. It bonds effectively to concrete, brick, stone, and masonry, making it a versatile solution for both indoor and outdoor waterproofing and crack repair needs.
Q: How do I apply the Concrete Crack Filling Sealant?
A: The sealant is ready to use right out of the package — no mixing required. Clean the surface to be repaired, removing any loose debris or dust. Apply the sealant directly into the crack or onto the surface using a spatula, brush, or applicator tool. Smooth it out evenly and allow it to cure fully before exposing to water or heavy use. For best results, apply in dry conditions.
Q: Is this sealant weatherproof and UV-resistant?
A: Yes. This sealant features strong weather resistance, designed to hold up against UV radiation and temperature changes over time. Once cured, it maintains a durable, flexible waterproof barrier that stands up to rain, sunlight, and seasonal temperature shifts — making it ideal for exterior roofing and outdoor concrete applications.
Q: How much area does the 100g sealant cover?
A: Coverage will vary depending on the depth and width of the cracks or the thickness of the application layer. The 100g size is best suited for targeted spot repairs — such as sealing individual roof cracks, small wall fissures, or isolated damp patches — rather than large-scale waterproofing projects.
