HPMC forms a protective film around the water molecules, preventing them from evaporating too quickly. This prolonged water retention allows for better hydration of cement particles, ensuring proper curing and setting of the mortar. It also reduces the risk of shrinkage cracks, which can occur when the mortar dries too quickly.

Lastly, HPMC enhances the overall performance of dry-mixed mortar. It improves the workability, consistency, adhesion, and water retention capacity, resulting in a high-quality mortar mixture. The use of HPMC ensures that the mortar is easy to use, provides a smooth and even finish, and forms a strong bond with the substrate. This ultimately leads to improved construction efficiency and durability of the finished structure.

In conclusion, HPMC offers several advantages in dry-mixed mortar. It improves the workability and consistency of the mortar, enhances its adhesion properties, and increases its water retention capacity. The use of HPMC results in a high-quality mortar mixture that is easy to use, provides a smooth finish, and forms a strong bond with the substrate. With these advantages, HPMC is a valuable additive in the construction industry, contributing to improved construction efficiency and durability.
