Thin Set Mortar Uses

Thin set adheres tile to surfaces

Thin set is an adhesive used to set tiles in a thin layer of mortar. Manufacturers typically sell it in a dry form. To use thin set, add water according to the manufacturer's specifications and spread it out with a trowel.

Function

Thin set mortar is a blend of cement, aggregate and special additives. This type of cement is designed to adhere well in thin layers that are usually no more than 3/16 of an inch thick. It is an adhesive that is used to set interior and exterior tiles.

Benefits

Thin set tends to be less expensive and faster to apply than other methods used to tile surfaces.

Preparation

Clean all surfaces thoroughly before applying thin set. Remove all grease, dirt, paint, mildew, oil and any other foreign contaminants.

Considerations

Thin set will follow the surface's contours

Thin set will not level surfaces. Thin set follows the contours of the surface. Thin set will not be able to compensate for high and low spots on the surface that can lead to uneven pressure on the surface and eventually to cracked tiles.

Types

Thin set is available in a wide range of strengths according to the substrate where you will use the thin set. Different companies produce several different types of thin set that vary along the lines of drying times, bonding properties, water resistance and shrinkage factors when applying the thin set in a thicker application.
