Calcium Chloride - 2kg (Dihydrate Flakes)

I used the calcium chloride flakes for speeding up the curing process of a concrete plinth that I build in my back garden. I used approx 1.5 bags of flakes for roughly 2.5 cubic meters of concrete and dissolved it in warmer water (not boiling water). Despite the winter conditions, freezing during the night and melting snow during the day, the concrete cured really well and I was able to start finishing the surface after 8 hours. Really happy with the result and the calcium chloride flakes clearly helped.

Great product at a reasonable price. I bought this product so that I could reuse a plastic dehumidifier that I had bought. This product has worked excellently as a dehumidifying agent and will help me to reduce my plastic usage.

Bought this pack to divide up and make my own small dehumidifier pouches. Starts to soak up moisture quite quickly so keep very dry until required. Does the trick and works out cheaper than buying individual de humidifiers.

If you need things dehumidified then please try this gem of an item. Fill your device and allow it to pull water from your fetid air. Use the extracted water for healthy nutrition for plants.

Good product.

Placed the caCl in a sock and left it in a glass for a few weeks and could see moisture being trapped. So did its job well.

Its good! use it all the time

I bought this to reduce condensation in my room and it worked well. Tried to reorder the same 2 kilo packet but the price doubled. Bag was 8.99 and now nearly £18. Not worth it. There are other sellers for same old price.
