Tile mortar is a special mortar used to fix tiles during tile installation, and is an indispensable material in tile-laying projects. Mortar not only has the function of bonding tiles, but also has important functions such as filling gaps, adjusting the flatness of tiles, and improving the service life of tiles. This article will introduce the types, properties, and precautions for use of tile mortar.

Types of tile mortar

Cement mortar

Cement mortar is the most widely used mortar, which is made by mixing raw materials such as cement and quartz sand. Cement mortar has the characteristics of high hardness, strong compressive strength, and not easy to shrink. It is a kind of mortar with high-cost performance.

Epoxy mortar

Epoxy mortar is a mortar made by mixing raw materials such as epoxy resin, hardener, and filler. Epoxy mortar has the characteristics of strong adhesion, and chemical corrosion resistance, and is not easy to be affected by moisture. It is a high-quality mortar.

Tile glue

Tile glue is a kind of water-based emulsion mortar, which is made by mixing raw materials such as polymer emulsion and filler. Tile adhesive has the characteristics of strong adhesion, no air bubbles, etc., and is convenient for construction. It is a mortar suitable for special environments.

The performance of tile mortar

Bond strength

The bond strength of tile mortar is an important index to evaluate the quality of mortar. During the tile installation process, the bond strength between the tile and the base layer directly affects the quality of paving and the service life of the tile. Therefore, it is very important to choose a mortar with high bond strength.

Water resistance

Tile mortar is prone to problems such as peeling or cracking in the case of long-term moisture, so water resistance is another important performance index of mortar. Good water resistance can ensure that the tiles will not be damp for a long time after laying, and will not fall off.

Mildew resistance

In a humid environment, the tile mortar is easy to breed mold, which affects the appearance and service life. Therefore, the mildew resistance of mortar is also one of the important considerations.

Construction performance

The construction performance of tile mortar directly affects the construction quality and progress. Good mortar should be easy to construct, not easy to produce air bubbles, and not easy to crack and other problems.

Matters needing attention in the use of tile mortar

Grassroots treatment

Before the tile mortar is laid, the base layer must be treated, the base layer must be cleaned, and problems such as empty drums and cracks must be dealt with to ensure that the mortar can effectively bond the tiles.

Mortar ratio

The proportion of mortar is a key factor in the tile-laying process, and different types of mortar need to be prepared according to different proportions. If the ratio is not appropriate, it is easy to cause the mortar to be too dry or too thin, which will affect the bonding strength and construction effect.

Construction temperature

The construction temperature of tile mortar should be between 5°C and 35°C, avoid construction at too low or too high a temperature. At the same time, it is also necessary to maintain the humidity of the base and mortar during the construction process to avoid problems such as cracking.

Construction tools

In the process of tile laying, it is necessary to use special mortar laying tools to ensure that the mortar is evenly applied and avoid uneven thickness.

In short, choosing the tile mortar that suits you is an important factor to ensure the quality of tile laying. When using tile mortar, it is necessary to pay attention to the type, and performance and use precautions of the mortar to ensure the quality and service life of the tile laying.
