Customer Questions & Answers
-
Question:
What is Sikaflex Self Leveling Sealant used for?
Answer: Sikaflex Self Leveling Sealant is primarily used for sealing horizontal expansion joints in concrete surfaces. This polyurethane-based sealant is designed to fill gaps and cracks, providing a smooth, level finish that can withstand movement. It is particularly beneficial for outdoor applications where exposure to varying temperatures and moisture occurs, such as driveways, sidewalks, and parking lots. -
Question:
How does the accelerated curing capacity of Sikaflex work?
Answer: The accelerated curing capacity of Sikaflex allows it to set and harden quicker than traditional sealants. This faster curing time is essential for projects that require a quick turnaround, making it ideal for professional contractors and DIY enthusiasts. This feature not only increases project efficiency but also minimizes downtime, allowing surfaces to be used shortly after application. -
Question:
Can Sikaflex Self Leveling Sealant be used in wet conditions?
Answer: Yes, Sikaflex Self Leveling Sealant can be applied in damp conditions but is not recommended for underwater applications. It adheres strongly to various substrates, including concrete, even when there's moisture present. However, for the best results, applying on a clean, dry surface is ideal. This flexibility makes it suitable for areas prone to rain or moisture. -
Question:
What colors does Sikaflex Self Leveling Sealant come in?
Answer: Sikaflex Self Leveling Sealant is available in gray, which complements most concrete surfaces and provides a discreet finish. This neutral color blends well with outdoor environments, enhancing the overall appearance of sidewalks, driveways, and patios while effectively sealing joints. For those seeking specific aesthetics, painting over the cured sealant may be an option. -
Question:
How do you apply Sikaflex Self Leveling Sealant?
Answer: To apply Sikaflex Self Leveling Sealant, start by preparing the joint or crack by cleaning it of any debris, dust, or old sealant. Using a caulking gun, fill the joint directly, allowing the sealant to level itself for a smooth finish. Ensure you’re within the specified application temperature range for optimal performance. Following these steps will result in a robust, durable seal. -
Question:
Is Sikaflex Self Leveling Sealant suitable for vertical surfaces?
Answer: Sikaflex Self Leveling Sealant is primarily designed for horizontal surfaces. While it can adhere to vertical applications, it is not recommended due to its self-leveling properties, which are optimized for flat surfaces. For vertical joints or cracks, consider using a polyurethane sealant that is specifically formulated for those applications. -
Question:
How long does Sikaflex Self Leveling Sealant take to cure completely?
Answer: Sikaflex Self Leveling Sealant typically cures within a few hours for touch, but full curing may take longer depending on environmental factors like temperature and humidity. For optimal performance, it's advisable to allow a full 24 hours before exposing the sealed area to heavy traffic. This ensures that the sealant achieves maximum adhesion and flexibility. -
Question:
Can Sikaflex Self Leveling Sealant be painted over?
Answer: Yes, once Sikaflex Self Leveling Sealant has fully cured, it can be painted over with compatible paints. This feature allows for better aesthetic integration into your landscape or structure. It's advisable to use latex-based paints for the best adhesion, ensuring not to compromise the sealant's flexibility and durability. -
Question:
What temperature range is suitable for applying Sikaflex Self Leveling Sealant?
Answer: Sikaflex Self Leveling Sealant should be applied when temperatures are within 40°F to 100°F. Ensuring the environment is within this range helps the sealant cure properly and achieve its maximum strength and adhesion. If working in colder conditions, it's crucial to monitor the weather and possibly wait for more favorable temperatures to ensure the best bonding results. -

SIKA Joint Sealants Editorial Review
Sikaflex Self Leveling Sealant is a polyurethane-based sealant that is heat-resistant, paintable, and has an accelerated curing capacity—making it ideal for sealing horizontal expansion joints in concrete. Although it is primarily used for wide joints in concrete around pools and in expansion joints, it is versatile enough to be used in sloped driveways, crack filling, and even roadway projects. The product should be used in a thin application, either with foam joint material or sand below it, and typically is only 1/4 to 1/2" thick. Customers have also advised waiting for it to start to set, then cover the surface with fine washed sand (no dust) to give it a better appearance and to extend its life beyond what it would be without some UV protection. Don't be fooled by the packaging, though. It takes a special gun applicator to apply this to the concrete, so make sure you have the right equipment before purchasing. The 29 oz canisters are better suited for bigger jobs, so buy accordingly. Overall, customers love this product because it easily fills in gaps and crevices to seal water from going into cracks. The value is great, and it's the same price as the big box store but delivered right to your door.
