Cellulose ethers are a critical building block for gypsum based plasters especially with machine application. This increases the lubrication of dispersed particles, resulting in a smooth, easily mixed, homogeneous plaster. The capability to retain water enables the plaster to hydrate over a longer period of time and develop a high mechanical strength. Controlled and stable setting is the most important quality criteria for gypsum plaster This application contributes to saving time and costs as they allow extending the time the plaster can be applied and worked. Furthermore, it brings consistency and plasticity to the mix for excellent workability. Plasters made with these additives spread and even out easily with a ‘feel’ that users appreciate. They enhance the bonding of the plaster to a variety of substrates and allow for a greater resistance and adhere firmly as soon as applied.
Gypsum has proved to be a miraculous material aiding interior construction. Gypsum surface plaster is one form that has caught the attention on the sector and is growing in popularity. The oldest example of usage of gypsum as an internal plaster is found in the Pyramids of Giza in Egypt which were lined with gypsum stucco plaster centuries ago and are still intact, which is proof of the durability & performance of this product.
