Cement Render

Exterior walls made of block, concrete, or ALC blocks can be coated with cement-based renders using either hand plaster or a sprayer. The addition of YibangCell® cellulose ethers to the mix can help manage the water demand and improve the workability and sag resistance of the render. KimaCell® cellulose ether is also effective in reducing shrinkage or expansion of the cementitious renders during the curing process by providing high water retention. When cement renders undergo excessive shrinkage or expansion, cracks may appear, but the use of cellulose ether can prevent these issues. In summary, YibangCell® cellulose ethers are a valuable addition to cement-based renders for exterior walls, as they can improve the processability and durability of the render, while reducing the risk of cracks and other defects.

● Cellulose ethers enhance cement-based plaster's water retention and offer other benefits.

Cellulose ethers have several benefits for cement-based plastering. Firstly, they dissolve quickly and disperse dry particles evenly, resulting in a smooth and uniform rendering. Secondly, they improve the rheology of the plaster, providing excellent workability, consistency, and preventing sagging. Additionally, cellulose ether's high water retention allows for an extended working time and can retain water for longer, leading to full hydration of the cement and the development of high mechanical strength. These advantages make cellulose ether a valuable additive for plastering, ensuring high-quality and durable results.
