Avoid wet and humid conditions. Store in a more storage-appropriate dry environment.
Tile mortar is a 100% local product that can be easily used for laying tiles on a concrete surface without having to cut the mortar on the floor surface.
The required consistency can be achieved by mixing a 20 kg bag with 4 liters of water. No further addition of cement is needed. It can be used for a longer period of time from the time of mixing. Prevents the hollowness of tiles.
