Let's compare the usage of three common tile adhesives.
For most tile installations, it is recommended to use a 3/16-inch thick layer of thinset beneath the tile. This creates a strong and stable foundation that helps prevent cracking and tiles from popping up. However, it's important to note that this thickness may not be suitable for all types of floor tiles.
When it comes to heavy tiles, a thicker layer of thinset is needed. If the thinset layer is too thin, it increases the risk of tiles eventually popping up or cracking. In such cases, it is advisable to use a 1/8-inch thick layer of thinset.
By using the appropriate thickness of thinset, you can ensure a secure and durable tile installation. So, make sure to choose the right thickness based on the type and weight of the tiles you are working with.
- A square-notched trowel with even tooth spacing creates a thinset layer that is one-half the tooth depth.
- A 3/8″ x 3/8” square notch trowel creates a 3/16” thick layer of thinset. The standard size.
- A 1/4″ x 1/4” square notch trowel creates a thinset layer 1/8″ thick. Better for heavy tiles.
THINSET
Thinset is a versatile mixture of cement, finely graded sand, and a water-retention compound. It is widely used for wall and floor tile installations. One of the key advantages of thinset is its ability to be used in wet areas, including those that will be completely submerged in water. When using thinset on surfaces other than concrete, it is recommended to use a layer of cement board or a similar backing for better bonding, especially when compared to wood or drywall. The application of the mortar adhesive is typically 3/8" thick or less.
MASTIC
Mastic comes in various forms such as thin-liquid, thick glue, or paste. It is suitable for use in dry or damp areas, but it should not be used in areas that will be submerged in water. Mastic is known for its strong hold, ease of application, and quick setting time. It is commonly used for tile installations on walls, wainscots, and dry backsplashes. Mastic should be applied thin, no more than 3/16 inch thick.
MUDSET
Mudset, also known as a thick-set mortar bed application, is composed of sand, cement, and water. It provides a solid, flat, and level floor, a water-resistant base, and structural stability for both new and old floors. It can help correct uneven sub-floors and create an optimal surface for tile adhesion. The thickness of the mortar bed also allows for floor sloping, such as in showers, to ensure proper drainage. A thick-set or mud-set tile installation involves placing finish tiles over a 1-1/4" to 2" thick portland cement mortar bed.
Proper installation of framing and substrate is crucial for achieving a high-quality tile installation. It is essential to always read and follow the manufacturer's instructions, as well as adhere to the specified specifications and guidelines.
