I'm wanting to get a good seal around the wheel arch.** A: This product is waterproof, UV resistant and a flexible adhesive - so, yes, this could be used as you describe. You WILL have to ensure the part of the wheel arches are clean and grease free prior to use. I would advise Isopropyl Alchohol wiped on the cleaned surface, let air dry and then use the Sika Flex either run a bead directly on the wheel arch or along the mudflap edge that will connect to the wheel arch. **Q: Can i use this to attach a cable entry gland to my caravan roof? Is this a waterproof sealant as well?** A: In principle Sikaflex®-552 AT can be used for this type of caravan application provided common sense design rules are applied. However, cable entry glands are normally a rubber type material and achieving a bond to this can be difficult. It’s important some tests are performed with the chosen sealant on the substrates to ensure a good bond can be achieved and no other effects to the substrates are observed. Positioning the cable gland so it’s not in standing water (horizontal) would also improve the situation. Please consult pre treatment guide and relevant TDS prior to full works. **Q: This can be used to do round camper van out door window frames and is this waterproof** A: Hi, no this is not suitable for your application unfortunately. Please contact Sika Industry Technical Support for further information. **Q: Is this a sealant as well as an adhesive? e.g suitable to seal the roof of a motorhome?** A: Product is a pure adhesive ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant *by A***T on 9 May 2026* Excellent. Goes on well and sticks really well ### ⭐⭐⭐⭐⭐ Great quality *by F***D on 14 May 2026* Really great product that works ### ⭐⭐⭐⭐⭐ Rock solid adhesive for fibreglass to metal bonding *by M***R on 25 February 2025* Used it to bond fiberglass to metal, and it holds rock solid with no movement. It’s flexible, strong, and durable, perfect for automotive applications. Pros: Excellent adhesion, great for metal and fiberglass, long-lasting bond. Cons: Messy to work with—wear gloves, as it’s hard to clean off hands. Keep thinners nearby for cleanup. ## Frequently Bought Together - Sika – Sikaflex -552 – Professional Use Primerless Hybrid High-Performance Assembly Adhesive – Gap Filling – For Internal And External Use – Black – 300ml Cartridge - Solar Double Cable Entry Gland, Waterproof Solar Photovoltaic Plastic Bracket Curved Cable Connector ABS Dual Cable Entry Housing for Solar Panels of RV Caravan Boat - Sikaflex-522 weather-resistant, UV-stable, adhesive sealant (new version of Sikaflex-521 UV and Sikaflex-221i) 300ml black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/65989887-sika-sikaflex-552-primerless-hybrid-assembly-adhesive-black-300ml-professional](https://www.desertcart.us/products/65989887-sika-sikaflex-552-primerless-hybrid-assembly-adhesive-black-300ml-professional) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-25*
