Although they have their similarities, mortar and grout are different materials that are used for different projects; while one is more of a filler between tiles, the other is used for adhesion. The two also vary from each other in terms of composition, application, and characteristics. Here is a look at a few of the differences between mortar and grout.
When considering the differences between mortar and grout, it helps to first look at the consistency of the material. Grout contains just enough water to keep its components together while still allowing it to be poured. Mortar, on the other hand, is typically smooth and able to be spread. While mortar is composed of hydrated lime and water, the composition of grout may vary by its coarseness; the more coarse the grout, the larger the aggregates involved.
There are further differences between mortar and grout than their consistencies, which is why they are suitable for use in different situations and for different projects. They also differ in terms of density and hardness. Grout is a tough, dense material, and these characteristics contribute to its water resistant properties. Mortar is stiff, but it is porous and not as hard as grout; it also features some level of breathability.
Mortar and grout can be used interchangeably, but only in very specific situations and under the recommendation of an architect or mason. Mortar tends to be best suited for laying bricks or other stone blocks, while grout is more appropriate for bathroom or kitchen tile; grout is particularly effective in bathrooms and kitchens due to its ability to remain unchanged in the presence of water.
