I think you will get a idea of coverage there. **Q: Can i use this to paste wood to Concrete ?** A: I have not used it for that. There are a bunch of products on the market that are made to glue wood to concrete. Check with your local building supply store. My understanding is that this West product is for fiberglass to fiberglass ,wood to wood ect. **Q: i bought the 105 and 206 with pumps as set. reading further i dont know if i got the correct products. using on reclaimed pine flooring. any opinions?** A: it works fine for filling voids in wood slabs but it is not a finishing product **Q: How much VOC is there in this product?** A: Hello Adu. There are 9.59 g/L (0.08 lb/gal) of VOC's in the combined resin/hardener system of 105/206.

As always, product does what it says it will and work s perfectly. Just you wish it was a little cheaper as the price seems a bit inflated but about the same that you would spend at a store. ### ⭐⭐⭐⭐⭐ Good Product, *by A***R on December 22, 2025* Good Product, A++ ### ⭐⭐⭐⭐⭐ Best option for typical applications *by E***N on April 18, 2026* I use West Systems epoxy constantly. The slow hardener is the best overall option. It takes overnight to set up but you are rewarded with a super glue job. I use this with 105 rather than any aliphatic wood glues. Wood glues are only when I need something simple and fast like fixing a stripped screw hole. ## Frequently Bought Together - West System 206-B Slow Hardener - West System 105-B Epoxy Resin - WEST SYSTEM 300 Mini Pump Set --- ## 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.at/products/2195958-west-system-206-b-slow-hardener](https://www.desertcart.at/products/2195958-west-system-206-b-slow-hardener) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-27*
