What is Deck Mud?

Deck mud, also known as floor mud or dry pack mortar, is a simple mixture of sand, cement, and sometimes lime, used primarily in the construction industry. It is typically used to create a flat, level surface, such as a shower pan or a floor, before the installation of tiles or other finishes. The mixture is called "deck mud" because of its low water content, which gives it a dry, crumbly texture that can be easily shaped and smoothed. The ratio of sand to cement can vary, but a common mixture is 5 parts sand to 1 part cement. Lime may be added to increase the mixture's workability and durability. Once the deck mud is spread and packed down, it forms a sturdy, stable base for further construction.
