Differences between Sand Topping Mix and Cement Mortar

The Recipe Differences for Thinset Mortar and Sand Topping Mix

By Mark J. Donovan




The words cement, concrete and mortar are commonly used interchangeably. However, the truth is that cement, or more specifically Portland cement, is the key binding agent in both concrete and mortar. Concrete is formulated using a combination of Portland cement, sand, and gravel, depending upon the desired strength of concrete. Similarly, mortar, or thinset mortar, is formulated using a combination of Portland cement and sand. With thinset mortar finer sand is used.

Sand Topping Mix is made from a combination of Portland cement and a mixture of sand. Normally the recipe for sand topping mix is three parts sand to one part Portland cement.

It is typically mixed with water to produce a stiff mud consistency. It is commonly used in the construction of floors for ceramic tiles, as well as used for filling material in masonry block cores and chimney construction.



It is easier to spread and creates a stronger strength shower floor base for laying ceramic tile.

Thinset mortar is used for actually applying ceramic tiles to a shower bed or walls. Thinset mortar is again a combination of Portland cement and a fine sand mixture, however, the ratio of sand to cement is different. With thinset mortar the ratio of cement and sand is one to one. Thus it is a stickier mixture that produces better adhesion. It is either mixed with water or a special latex liquid additive to produce a thick slurry.
