It doesn't really dry as it remains pliable like rubber. I would however heed the suppliers advice and try not to apply it below 5c/40f if possible. **Q: Approximately how many square feet will one 5 gallon bucket cover?** A: 100-125sq ft at a 60mil thickness. Bought 5, 5gal buckets to do 580sq ft of foundation and had about 1/2 gallon left over at an average of 60mil thickness. **Q: can i use in wood? i want to do wooden pots** A: Yes, you can use the Liquid Rubber Foundation Sealant in wooden pots or planters. Please see the Liquid Rubber USA site for more specific application info. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5stars *by T***. on 28 April 2024* Great stuff i put this down on my bk yard as the dogs were getn burns off layn on the concrete for so long on there legs, this has worked a treat nice coat over the concrete now an looks great 👍🏽 would definitely buy this again!!! ### ⭐⭐⭐⭐⭐ Great value *by S***H on 9 October 2026* Great value ### ⭐⭐⭐⭐ Easy to apply *by T***Y on 10 February 2024* Basically time will tell! Looks solid when dry. I applied three coats for damp proving a cupboard wall,which was suffering from rising damp. no damp seems to be registering in a damp collector I have put in the cupboard so far. The damp solution dries quite hard. Can’t understand why they call it a rubber coating!Seems to have no or very little flexibility to me. In summary, quite happy with the results thus far. ## Frequently Bought Together - Liquid Rubber Basement and Foundation Repair Sealant - Waterproof Concrete Sealer & Crack Filler - Flexible Coating for Indoor & Outdoor Use - Waterproofing Paint - Black, 1 Gallon - Liquid Rubber Geo-Textile - Fix Leaks - Repair and Restore - Easy to Use, 4 Inch x 160 Foot Roll - Liquid Rubber Caulk - Hybrid Adhesive and Protective Sealant, White, 1 Pack --- ## 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.us/products/226805744-liquid-rubber-concrete-foundation-and-basement-sealant-indoor-and-outdoor](https://www.desertcart.us/products/226805744-liquid-rubber-concrete-foundation-and-basement-sealant-indoor-and-outdoor) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-26*
