I did a couple of coats an still had a bunch left over. It really does help to lock in the foam. It dried very fast. I would 100% buy again but I won't have to because I still have a bunch. Great deal. Great heat retention. Easy to apply. Really toughens the foam, and it comes in a big bottle! ## Frequently Bought Together - Colloidal Silica Rigidizer - Coating for Refractory Ceramic Fiber Products - 1 Quart (40 Oz Approx.) - Mr Volcano Refractory Satanite 4.5 Pounds for Ceramic Blanket Lining 3200 Degree Mortar - Ceramic Fiber Insulation, 1" Thick x 16" x 48", 2400F Fireproof Insulation Blanket, 3026E --- ## 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.tn/products/368727228-colloidal-silica-rigidizer-coating-for-refractory-ceramic-fiber-products-1](https://www.desertcart.tn/products/368727228-colloidal-silica-rigidizer-coating-for-refractory-ceramic-fiber-products-1) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-23*
