Very good. *by R***N on 28 February 2026* Thinker than most silicon sealants. High with and brightness. I used it because the marble worktop fitter used and recommended. It's not cheap but it is good. ### ⭐⭐⭐⭐ A great sealer but expensive *by P***R on 15 March 2025* The sealer works very well indeed, I used it first on a Twusch fitting to my Thetford Toilet, but I will continue to use it elsewhere, but it is expensive compared to the ordinary sealer from a local hardware store. Is it worth it? I'm not sure, but it is very easy to use and, hopefully, will last a long time. ### ⭐ Avoid this mess *by V***D on 30 June 2025* Unless you have 10 years of hands-on experience applying silicone for 10 hours a day, I strongly recommend staying away from this product. It’s incredibly thick, and applying it evenly or neatly is nearly impossible. It will stick to everything it shouldn’t — and almost certainly won’t stick where it’s actually needed. I don’t question the skills of the engineers behind this formula, but they clearly need to sit down with their marketing team. Because before you can appreciate the supposed quality of this product, you have to somehow manage to apply it correctly — and that’s just not going to happen without a five-hour instructional video (which, by the way, doesn’t exist). And here’s the cherry on top: for your £18, they don’t even bother including a nozzle. Apparently, it’s so “premium” you’re expected to go buy one separately. ## Frequently Bought Together - Otto Seal S 100, Sanitary Silicone, White, 300 ml - Joint Smoother Set 5 Pieces – Joint Scraper Set for Silicone and Acrylic - Classic (Plus) Fugenfux® Set of 5 – Joint Smoother | Joint Puller with Revolutionary Magic Tip for Extremely Tight Areas | 5 Optimised Special Joint Heads | Made in Germany | For All Sealants --- ## 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/49909820-otto-seal-s-100-sanitary-silicone-white-300-ml](https://www.desertcart.gr/products/49909820-otto-seal-s-100-sanitary-silicone-white-300-ml) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-05*
