Wanting to use as a mother mold** A: It never sets - it remains soft and pliable. I would use hydrocal for the mother mold or reinforced fiberglass with epoxy. **Q: Does this cure flexible or rigid?** A: This product does not cure at all. It remains pliable indefinitely **Q: Does this putty maintain its shape once molded, like modeling clay, or does gravity cause it to melt back down?** A: Yes and it was very easy to work with. it did not stick to you hands and you could mold it very easy. **Q: Wrap around outdoor speaker wire (binding post connection) for additional waterproofing? Want something removable for winter storage of speakers.** A: This is potentially messy for that application. Try using E/FUSING 112 to wrap wires to protect them from elements. ## Frequently Bought Together - 900 Moldable Silicone Putty - Grey - Rectorseal 81880 1-Pound Duct Seal Compound Gray - Zxfuture Pack of 20 White Seal Putty Waterproof Duct Seal Repair Sealing Clay, Quick Mending Mud for Drain Connection, Wall Hole, Air Conditioning Hole --- ## 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://congo.desertcart.com/products/139748118-900-moldable-silicone-putty-gray-rectangular-shape](https://congo.desertcart.com/products/139748118-900-moldable-silicone-putty-gray-rectangular-shape) --- *Product available on Desertcart Congo* *Store origin: CD* *Last updated: 2026-11-05*
