I’ve used Sikaflex 221 several times over the past year for various automotive and general fixing jobs, and the performance is far superior to basic alternatives.The adhesive strength is excellent. Once applied, it bonds very firmly and creates a durable, flexible seal. It works well on multiple surfaces including metal and plastic, making it ideal for vehicle modifications and exterior applications.It’s especially useful where a strong, permanent bond is required. After curing, it remains slightly flexible, which helps prevent cracking due to vibration or movement.One important thing to be aware of is how sticky it is. If it gets on your hands, tools, or unintended surfaces, it can be difficult to remove. Careful application and preparation are essential.Pros:• Extremely strong adhesion• Professional-grade quality• Works on multiple surfaces• Flexible once cured• Ideal for automotive and outdoor useCons:• Difficult to remove if applied accidentally• Requires careful handling during applicationOverall:A high-quality adhesive and sealant that provides excellent strength and durability. Ideal for automotive, DIY, and permanent bonding applications where reliability is important. ### ⭐⭐⭐⭐⭐ Professional grade product at reasonable prices *by on Reviewed in the United Kingdom 6 February 2026* Sika products are seriously good products, expensive but worth every penny. I used this to bond 12mm marine ply to line the tops of the doors on my van , use disposable gloves because it will tack and stick to pretty much everything…. Its leak prevention is excellent, easy to use and very effective.Be warned though it sticks to everything so be careful you don’t get it on anything you don’t want it on because it’s almost impossible to remove easily.Sika make a lot of very specific products so do a little research first to find the exact product for your particular task …… you will be surprised at what they actually provide. This is professional grade products, very strong and can be used as a sealer as well as an adhesive. I found that if you wrap up the tube after use and seal it I can actually get a few days use out of the tube before it finally hardens.. ### ⭐⭐⭐⭐⭐ Great product. *by on Reviewed in the United Kingdom 17 August 2026* Great product. ## Frequently Bought Together - Sika Sikaflex 221 Adhesive Sealant, Black, 300 ml - Sika Sikaflex-522 Caravan And Motorhome Adhesive Sealant – Weather And Mould Resistant – White – 300ml - HouYeen Black Porthole 10'' Opening Window Port Hole Portlight Hatch for Boat Yacht RV Industry --- ## 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.gr/products/50806593-sika-sikaflex-221-strong-adhesive-sealant-black-300ml](https://www.desertcart.gr/products/50806593-sika-sikaflex-221-strong-adhesive-sealant-black-300ml) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-28*
