By adding HPMC, the viscosity of the mix is increased, reducing the likelihood of sagging and allowing for vertical applications without compromising the quality of the finish.

Moreover, low viscosity HPMC is compatible with a wide range of additives commonly used in mortars and plasters. It can be combined with other admixtures such as air entrainers, plasticizers, and accelerators without negatively affecting its performance. This versatility makes it a valuable tool for contractors and manufacturers looking to optimize their mix designs.

In terms of application, low viscosity HPMC can be easily incorporated into mortar and plaster formulations. It is typically added during the mixing process, either as a dry powder or a pre-mixed solution. The dosage depends on the desired workability and specific requirements of the project.

In conclusion, low viscosity HPMC offers numerous benefits in enhancing the workability of mortars and plasters. Its ability to improve flow, adhesion, water retention, sag resistance, and compatibility with other additives makes it an invaluable tool for construction professionals. By incorporating low viscosity HPMC into their mix designs, contractors and manufacturers can achieve better results, saving time and resources in the process.
