Coatings & Adhesives Plaster & Joint Fillers Plaster & Joint Compounds

When an interior wall is constructed using gypsum or wall board, a high-quality tape joint compound makes certain that the end result not only looks great but is smooth as well. Joint compounds (also called taping muds) need to efficiently fill the spaces that occur when sheets of wall board meet, hide the edges of the joint tape, and sand well to ensure an even finish.

Plaster & Joint Fillers

Ground calcium carbonate, or ground limestone, is the most popular mineral in joint compound manufacture. GCC increases the worth of the products it is added to as it adds high brightness and acts as a cost-effective filler. It also makes for a good reinforcer in the final product.

Joint compounds are usually comprised of 70% GCC, and no more than 80%. Nowadays, though, it’s not uncommon to find levels of 30 or 40%. Carbonates that are utilised in joint compounds are typically 200 to 325 mesh products with top sizes (largest particles of 44 to 75 microns).

.Calcium Carbonates in Stucco

A durable and serviceable finish for building exteriors is stucco. It is quite popular, and is used as a decorative accent on a vinyl or wood-sided or brick house. It can also be used as an overall covering for every wall.  It offers protection and can be used on buildings of any size.

Traditionally, built-up stucco exteriors made use of a ground limestone or dolomite as the aggregate in the topcoat. Artificial stucco uses a four-part application wherein limestone is utilised in a few layers as a functional filler but as a texture aggregate in the top coat. The size of calcium carbonate filler chosen can range from 10 mesh to 200 mesh, with the size choice depending on the application.
