HPMC, on the other hand, may require additional effort to achieve the desired workability due to its lower water retention.
Furthermore, HEMC offers improved resistance to sagging or slumping. When applied vertically, such as when installing wall tiles, the adhesive or putty needs to have sufficient body and stability to prevent it from sliding down. HEMC, with its higher water retention and gel-like consistency, provides the necessary support to hold the tiles or putty in place during the drying process. HPMC, with its lower water retention, may not offer the same level of resistance to sagging, potentially leading to uneven or misaligned tiles.
In conclusion, HEMC is more suitable than HPMC for making cement tile adhesive and wall putty due to its higher water retention properties. The ability of HEMC to retain more water enhances the workability, adhesion, and resistance to sagging of the product. These qualities ensure a smoother application process, improved durability, and a longer lifespan for the tiles or putty. When choosing an additive for cement tile adhesive and wall putty, considering the higher water retention of HEMC can lead to better results and customer satisfaction in construction and renovation projects.
