However, the picture of the container says 27.5 ounces. Which is it?** A: The WEST Systems products are sold in several sizes. 7 oz round cans, 32 oz rectangular cans as shown here, and large rectangular cans of 126 oz. Try to confirm the size you are buying. **Q: Shelf life of 205 hardener? My cured epoxy (105+205) is soft, gooey, even when measured exactly with a syringe.** A: I believe 105 resin takes a higher proportion of hardener than 205 resin. Check the directions. **Q: How much faster than the "slow" hardener does the "fast" one cure?** A: On the manufacturer's website states cure time is 6 to 8 hours. The pot life at 72 degrees Celsius has 6 to 12 minutes to work with. **Q: Will the pumps work on the smaller 7 fl oz cans ?** A: I believe that if you purchase the set of 3 pumps, the smallest will fit the smallest container which is, I think, a pint. If you don't routinely use something like an eighth cup or more, you might want to consider buying some syringes from a farm supply store (a 60ml syringe for the resin and a 12 ml for the hardener). I recommend these sixes because the epoxy is mixed at a 5:1 ratio of resin to hardener and syringes of these sizes mix one major increment of one to one major increment of the other.

It's worth it! ### ⭐⭐⭐⭐⭐ Works as advertised *by on Reviewed in the United States December 3, 2023* West system products worked very well. Easy to mix and apply with use of measuring hand pump, and syringe. Used to harden soft spots on RV floor. Make sure your holes are NOT drilled completely through the floor, or product will just run through. This product has a thin viscosity in order to inject where needed. Takes time to harden. Starts to harden within about 10-15 minutes. Oder is minimal which was a great surprise. Still used in well ventilated area. ### ⭐⭐⭐⭐⭐ Fast and convenient *by on Reviewed in the United States April 28, 2021* This was my first time using West System epoxy. I bought this along with the kit with the 204A hardener. The 205 hardener worked great with plenty of working time for some butcher block waterfall counter tops I was assembling. Thick enough to address some minor gaping issues yet thin enough to squeeze out properly for a great wood joint. I've use the hardware store epoxies or small bottle epoxies for many years and finally bit the bullet for West System. More expensive upfront but much cheaper overall. It is so much more convenient. The pumps are quick and so much more accurate for ensuring a proper cure. I highly recommend this product. ## Frequently Bought Together - West System 205-A Fast Hardener - West System 105-A Epoxy Resin,Clear Pale Yellow - 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.tn/products/1960251-205-a-fast-epoxy-hardener-7oz-fast-cure-cooler-climates](https://www.desertcart.tn/products/1960251-205-a-fast-epoxy-hardener-7oz-fast-cure-cooler-climates) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-01*
