Customer Questions & Answers
-
Question:
What is Sikaflex -1C SL sealant used for?
Answer: Sikaflex -1C SL is a high-performance self-leveling polyurethane sealant designed for horizontal surfaces. It’s used primarily for sealing joints in concrete, masonry, and other building materials. This product excels in environments where water drainage is critical, such as parking decks, walkways, and other outdoor settings. Its self-leveling properties make it ideal in scenarios where a smooth finish is essential, ensuring durability and aesthetic appeal. -
Question:
How do you apply Sikaflex -1C SL sealant?
Answer: To apply Sikaflex -1C SL sealant, start by ensuring all surfaces are clean and free of contaminants. Use a caulking gun to apply the sealant directly into the joint or crack, allowing it to flow and level itself. It's important to apply the sealant in temperatures above 40°F for optimal performance. This makes it effective for both construction and repair projects, providing a reliable seal in various applications such as filling gaps in sidewalks or protecting foundations from moisture. -
Question:
What are the drying and curing times for Sikaflex -1C SL?
Answer: Sikaflex -1C SL typically skins over within a few hours, but full curing depends on environmental conditions such as temperature and humidity. Generally, it cures within 24 to 48 hours, making it important to avoid heavy traffic or water exposure during this time. Understanding these timelines is crucial for planning construction or repair schedules, especially in projects involving high-finish areas where time-sensitive installations are necessary. -
Question:
Is Sikaflex -1C SL suitable for exterior use?
Answer: Yes, Sikaflex -1C SL is highly suitable for exterior applications due to its exceptional weather resistance and durability. Once cured, it can withstand extreme temperatures, UV exposure, and moisture, making it ideal for outdoor installations like patios, driveways, and building expansions. This quality is especially beneficial for protective applications in harsh climates where other sealants might fail. -
Question:
Can Sikaflex -1C SL be painted over?
Answer: Sikaflex -1C SL can be painted after it has fully cured, which is critical for aesthetic projects. It’s important to use a compatible paint and primer to ensure proper adhesion. This feature allows you to match the sealant with the surrounding surfaces, ideal for enhancing the visual appeal of architectural projects or for maintaining the consistency of exterior designs. -
Question:
What colors is Sikaflex -1C SL available in?
Answer: Sikaflex -1C SL is available in various colors, including Limestone, which mimics the appearance of natural stone materials. The choice of color allows for versatility in design, making it suitable for both visible seams in creative projects and discreet joint fillings that blend seamlessly with surrounding materials. This is particularly advantageous for designers looking to maintain a cohesive aesthetic in walkways or patios. -
Question:
What makes Sikaflex -1C SL different from other sealants?
Answer: Sikaflex -1C SL stands out due to its self-leveling capabilities, which enable it to create a smooth, even surface without manual smoothing after application. Its polyurethane composition offers superior adhesion and flexibility compared to standard silicone sealants, making it suitable for dynamic joint movement. These qualities make it a preferred choice for professionals undertaking large-scale builds or renovations requiring high-performance materials. -
Question:
Can Sikaflex -1C SL be used on all types of surfaces?
Answer: Sikaflex -1C SL is compatible with a wide range of surfaces including concrete, brick, stone, and wood. However, it’s not recommended for use on surfaces where paints or coatings may peel off. This capability makes it a versatile option for many applications, such as filling control joints in concrete slabs or sealing around outdoor fixtures like planters and pools, enhancing the longevity of these installations. -
Question:
What is the shelf life of Sikaflex -1C SL sealant?
Answer: Sikaflex -1C SL has a shelf life of approximately 12 months when stored properly in a cool, dry place. This durability allows you to stock up for multiple projects without worrying about the product expiring too quickly, thereby saving costs in long-term planning. Proper storage can ensure the sealant maintains its performance and ease of application for future building or renovation needs. -

Sikaflex Urethane Adhesives Editorial Review
Sikaflex -1C SL High Performance is a self-leveling polyurethane sealant designed for various applications. Customers have used this product for years in multiple applications without issues - it is UV resistant and stain-resistant. One customer found it challenging to apply in wider cracks and recommended cleaning out gaps by wire brush, adding tight-fitting closed-cell backer rods, and adding the self-leveling sealant to the top of the concrete. The product is paintable after cure, but customers recommend testing a small, inConspicuous area for compatibility. The epoxy can be applied over this product once cured, but if the joints move, the epoxy will crack. Customers have complained about the cartridges being damaged during use, leaving caulk all over the place. One customer found it too runny, making it challenging to seal and level cracks, and recommended using a cheap silicone in the crack first to fill every void before using this product over the top to finish the job. Overall, customers recommend the Sikaflex -1C SL High Performance product, but with some caution.
