Sika® ViscoCrete® powder additive for dry mortar

Dry Mortar

Dry mix mortars are factory pre-batched multi-component systems. They are used for many different applications in both new construction and renovation projects. Typical uses include screeds, plasters and masonry mortars, floor levelling compounds, tile adhesives and grouts. Many other specialist products such as repair mortars, waterproofing and sealing slurries and injection mortars are also based on dry mortar technology.

Gypsum building elements on a construction site


Gypsum, chemically known as calcium sulphate dihydrate, is one of the most important minerals used in the production of construction materials. Today, the majority of gypsum binder, so-called calcined gypsum, is used for the manufacture of gypsum boards. Also known as plasterboards or drywall, they are lightweight building elements primarily used as an interior surfacing for building walls and ceilings. Gypsum board walls and ceilings have a number of outstanding advantages: they are fire-resistant, sound-attenuating, durable, economical and versatile.
