Mortar water retention is an important indicator of the stability of the internal components of fresh cement mortar. In order to make the hydration reaction of the gel material fully carried out, the right amount of cellulose ether can keep the water in the mortar for a longer time. In general, the water retention of the slurry increases with the increase of cellulose ether content. The water retention of cellulose ether can prevent the substrate from absorbing too much water too quickly and hinder the water evaporation, thus ensuring that the slurry environment provides sufficient water for cement hydration. In addition, the viscosity of cellulose ether also has a significant effect on the water retention of mortar. The higher the viscosity, the better the water retention.

Another important application of HPMC in construction is as a thickening agent in mortar and tile adhesives. HPMC increases the viscosity of these materials, preventing sagging and ensuring proper coverage on vertical surfaces. This property is essential for achieving a uniform bond between tiles and substrates, as well as for preventing slippage during the setting process
