It's not exactly powder or dust -- it's hard to describe; maybe kinda like fake snow. Do handle with care, but it not too bad. Good value; one bag will go pretty far. Be aware that it will noticeably lighten the color of your epoxy if you add a substantial amount. ### ⭐⭐⭐⭐⭐ Works perfect *by on Reviewed in the United States December 16, 2023* It worked better than expected. The only issue I had is it tinted the epoxy a dull white color but that was easy to work around. The project i was working on was a bathtub and i needed something to seal my edges du to stupid sheetrock work. So this worked for me with some minor tweeks. ### ⭐⭐⭐⭐ Does not dissolve clear *by on Reviewed in the United States July 31, 2024* Do not get this expecting it to turn up clear after mixing. It's kinda a pita to mix too. It does work well with pigments ## Frequently Bought Together - Stone Coat Countertops Epoxy Thickener (0.5 lb) Thickening Agent for Vertical, Sloped, and 3D Epoxy Projects, Boosts Bond Strength for MDF, Plywood, and Seaming, Non-Hazardous and Made in the USA - Stone Coat Countertops Quick Coat 1 Gallon – Fast Curing Liquid Epoxy for DIY Woodworking Projects Like River Tables, Geodes, Steel Inlays, Crack Filling, Seam Sealing and Coating 3D Objects - Stone Coat Countertops Epoxy Undercoat 1 Quart (32 Fl Oz White) High-Bond Epoxy Primer for MDF, Plywood, and Porous Surfaces – Essential for DIY Epoxy Countertop Kits --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/237172970-epoxy-thickener-0-5-lb-for-vertical-application-thickening-agent](https://www.desertcart.pt/products/237172970-epoxy-thickener-0-5-lb-for-vertical-application-thickening-agent) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-31*
