If you do not want to use the purchased materials immediately, you should always store them in a frost-free and dry place. Incidentally, this rule applies to almost all building materials. However, this applies in particular to materials that you can buy in the calcium silicate board store and are primarily intended for indoor use.
The materials that are mixed with water should therefore always be protected so that they do not react before the desired processing.
Information on the storage of the respective products can always be found under "Technical properties" on the individual product pages of our store.
