Q1: What is Sikaflex 11 FC+ used for?
Sikaflex 11 FC+ is a 1-component polyurethane adhesive and sealant designed for bonding and sealing most common construction materials, including concrete, masonry, timber, metals, glass, and ceramics. It works for both interior and exterior applications.
Q2: What colours and sizes are available?
Sikaflex 11 FC+ comes in Black, Concrete Grey, White, and Japan Beige. Sizes include 300ml cartridges, 600ml foil packs, and a bulk box of 20 cartridges for $400.
Q3: Can Sikaflex 11 FC+ be used outdoors?
Yes. It is weather-resistant and maintains elasticity under temperature changes. Always follow proper substrate preparation for best results.
Q4: How long does it take to cure?
Sikaflex 11 FC+ typically skins over in 45–60 minutes and reaches full cure in 3–7 days depending on joint size, temperature, and humidity.
Q5: Can I paint over Sikaflex 11 FC+?
Yes, once fully cured. Always test paint compatibility first, as some coatings may require primer or special preparation.
Q6: Is it safe for structural bonding?
Sikaflex 11 FC+ is not recommended for structural bonding or exposed structural glass. It is designed for general construction adhesive and sealing applications.
Q7: How do I choose between a single cartridge or a box of 20?
For small DIY projects, single cartridges are ideal. For contractors or large projects, the bulk box of 20 offers significant savings ($20 per cartridge) and ensures consistent colour supply across your project.
Q8: Do I need primers for certain surfaces?
Yes, for high-performance or non-porous substrates like aluminium, stainless steel, or glazed tiles, using Sika primers and activators (e.g., Sika Aktivator-205, Sika Primer-3 N) improves adhesion and durability. Porous substrates like concrete may also require Sika Primer-3 N.
Q9: Where can I buy Sikaflex 11 FC+ in Australia?
You can purchase directly from Epoxy Warehouse with Australia-wide shipping. Bulk orders are available for contractors and large projects.

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
