Improving Mortar Tiling with HPMC Additives

Jan. 23, 2026

HPMC (Hydroxypropyl Methyl Cellulose) is widely used in cement-based mortar formulations as a thickener, 

suspending agent and water retention agent. In tile mortar, these functions help formulators control fresh-mortar

consistency, water retention and application behavior.


The key is to select an HPMC grade that matches the formulation requirements rather than simply choosing the highest viscosity.


What Does HPMC Do in Tile Mortar?

HPMC can provide several important functions in mortar tiling applications:

1) Thickening: Helps control mortar viscosity and consistency.

2) Water retention: Helps the fresh mortar retain water during application.

3) Suspension: Helps maintain a more uniform mortar system.


These properties are relevant to the workability and stability of tile mortar. However, the final performance 

depends on the complete formulation, including cement, aggregates, polymers, water and other additives.


How to Choose HPMC for Mortar Tiling

A practical selection process is:

Application requirement → target mortar properties → viscosity grade → formulation testing


For example, if a tile mortar formulation requires a higher viscosity level, a high-viscosity HPMC grade can

be evaluated. If a lower viscosity is required for the target formulation, another grade should be compared.


Higher viscosity should not automatically be considered better. The objective is to find the grade that

provides the required balance of viscosity, water retention, suspension and workability.


HPMC Grades for Tile Mortar

JINTEDIFU offers HPMC grades with different viscosity levels for construction applications.


HPMC JINT™ 200000

HPMC JINT™ 200000 is a high-viscosity HPMC used as a thickener, suspending agent and water retention

agent. Its specified viscosity is above 160,000 mPa·s, and tile adhesive is one of its recommended applications.


It can be considered when a tile mortar formulation requires evaluation of a high-viscosity HPMC grade.

HPMC JINT™ 150000

HPMC JINT™ 150000 is another high-viscosity HPMC grade, with a specified viscosity range of 120,000–180,000

mPa·s. Tile adhesive is also listed as a recommended application.


It provides another viscosity range for formulators comparing HPMC grades for tile mortar.

How to Test HPMC in Tile Mortar

Before selecting a grade for production, a simple comparative test can help.


Keep the main formulation unchanged and compare different HPMC grades under the same mixing conditions.


Evaluate:

1) Fresh mortar consistency and workability.

2) Water retention.

3) Suspension and mortar stability.

4) Application behavior.

5) Relevant tile mortar performance according to the required standard or internal test method.


This approach allows formulators to compare grades based on actual formulation performance rather than viscosity alone.


Choosing the Right HPMC Additive

For mortar tiling applications, HPMC selection should start with the required mortar properties and then move to viscosity grade selection.


JINTEDIFU provides different HPMC viscosity grades for construction applicationsHPMC JINT™ 200000

and HPMC JINT™ 150000 are both listed for tile adhesive applications and can be evaluated according to the requirements of the formulation.


The final grade should be confirmed through laboratory testing and, where applicable, production-scale trials.
