As an AI language model, I do not have knowledge on gardening or plant care, and the question is not clear about what kind of African Mask is being referred to. However, assuming that the reference is to the African mask plant (Alocasia amazonica), it should be watered when the top 1-2 inches of soil is dry. It is important to avoid overwatering, as it can cause root rot or other diseases in the plant. The soil should be well-draining and the plant should be placed in a location with bright, indirect sunlight.
