Small addition.
Better workability.
HPMC is a non-ionic cellulose ether used to manage water and consistency in construction formulations.
From a mortar bed to a smooth wall finish, it helps turn a dry blend into a workable mix.
Find your applicationWater retention
Helps retain mixing water and reduce rapid moisture loss during application.
Smoother workability
Adjusts the feel and spreadability of mortar, putty and plaster mixes.
Controlled consistency
Provides thickening to help achieve the required body and application properties.
Formulation flexibility
Select the grade to match your binder, process and application requirements.

Different ways to build.
Explore where HPMC fits into your formulation, from cement-based mortars to finishing compounds.
Build consistency
into your mortar.
In cement-based dry-mix mortar, HPMC helps retain water and adjust rheology for workable, cohesive application.
- Water retention in cement-based mixes
- Controlled consistency during spreading
- Grade selection for your mortar system
A smoother path
to a finished wall.
In wall putty and skim-coat formulations, HPMC helps control water retention and application consistency.
- Smooth spreading under the trowel
- Consistent body in the mixed putty
- Water management during finishing
Workability for
gypsum systems.
For gypsum-based plaster, HPMC helps manage water and consistency. Match the grade to the binder and application method.
- Water retention during application
- Controlled thickening of the plaster mix
- Compatibility checked in your formulation

The essentials for evaluating HPMC in your next construction formulation.
Choose the grade, not just the viscosity.
Performance depends on the binder, formulation and application conditions. Confirm viscosity, dosage and test methods against the selected grade’s technical data sheet.

Common questions about HPMC for construction applications.
What does HPMC do in a dry-mix formulation?
HPMC acts as a water-retaining and thickening additive. It helps adjust the consistency and workability of mortar, wall putty and gypsum-based materials.
Can one grade be used for every application?
Grade selection depends on the binder, formulation and application method. A grade suitable for wall putty may not give the same result in a mortar or gypsum system. Evaluate it in your own formulation.
What information is needed to select a grade?
Start with the application, binder type, target viscosity, mixing method and working conditions. Use the grade-specific TDS and formulation trials to confirm suitability.
What is the pack size?
The product photographs show 25 kg bags. Packaging artwork and grade details should be confirmed for the supplied order.
