Joint Compound

Joint Compound Imerys minerals improve the rheology in joint compounds

Imerys offers a wide variety of products for the joint compound industry. When drywall is hung, it’s attached to studs with metal fasteners and a gap is left between individual sheets of drywall.  This gap is then covered with tape and topped with a joint compound to form a smooth surface finish that conceals any gaps or fasteners.
