Cement-based Renders

Joinway cellulose ethers are essential components of successful cement-based plaster formulations. Plaster must retain enough water for proper setting of the cement and to achieve high mechanical strength. Joinway cellulose ethers improve water retention of cement-based plasters and offer these additional advantages:
1) Easy Mixing
Joinway cellulose ethers, in plaster grades, dissolve very quickly, allowing the complete dispersion of all dry particles. Joinway additives enhance the lubricity of dispersed particles resulting in a smooth, homogeneous plaster. The surface activity of Joinway products helps entrain additional air for improved workability.
2) Application
Joinway cellulose ethers improve the rheology of the plaster for excellent workability and consistency. Improved consistency allows smoothing and evening without sagging. Joinway products give the plaster an ideal amount of stickiness so it adheres to the substrate wall, not to the working trowel. The high water retention properties of Joinway cellulose ethers also prolong working time.
Machine plaster requires a cellulose ether which dissolves very quickly, builds up consistency before the plaster is on the substrate, and shows no post-thickening on the wall. Joinway cellulose ethers help produce a plaster with good pumpability, excellent workability characteristics, easy finishing, and a homogenous surface.
3) Final Plaster Properties
Joinway cellulose ethers in the mix retain water for a longer period of time-longer water availability means the cement can fully hydrate and develop high mechanical strength. This produces a plaster with a homogenous surface, smooth, lump-free finish, and greater resistance to cracks.
