Plasters & Joint Fillers
Plasters are used for both decorative and functional purposes. Textured plasters require mineral particles with a mean diameter of up to 7mm and high brightness to meet the optical needs of customers. The plaster should also act as a water barrier yet allow water vapor permeability at the same time, to protect buildings from damage.
Other products, such as painters‚ fillings, are used to prepare the surface of a wall for the subsequent treatment. Operators require materials to be crack resistant and have good sandability to help them deal with rough surfaces.
These demanding requirements are achieved by selecting the right quantity and balance of fine and coarse mineral particles.
Natural calcium carbonate is an ideal mineral to design products that meet these specific requirements. The nodular particle shape of natural calcium carbonate offers good workability and enhances application properties. It improves the hardness and mechanical properties of the films.
The available products range from powder to granules and offer different particle size distributions. The customer therefore has numerous options for selecting the ideal mineral fillers for every application.
| Application | Calcium Carbonate Content |
| Plasters | up to 80% |
| Cement & gypsum based grouts | up to 50% |
| Polymer based grouts | up to 75% |
