zandcementanhydrietscreed

Zandcementanhydrietscreed is a cementitious floor screed that combines graded sand, Portland cement, and anhydrite (calcium sulfate) binder. It functions as a leveling and wearing layer for interior floors, typically applied over concrete or prepared subfloors. The mixture is designed for smooth substrates ready for tile, vinyl, or timber finishes.

Typical formulations contain approximately 60–70% sand, 20–30% cement, and 5–15% anhydrite binder by weight, with optional plasticizers or shrinkage-reducing additives. Some premixed blends use a higher anhydrite content. The product can be sold as a dry-mix to be wetted on site to achieve the desired consistency.

Performance features include good leveling, relatively high compressive strength, and a flat, dust-minimized surface. It can be used with underfloor heating when installed according to manufacturer guidelines. It is favored for renovations and new construction where a durable, ready-to-tile substrate is desired.

Key installation considerations include moisture control, substrate preparation, and compatibility with subsequent coverings. Anhydrite components react with water; curing and sealing are important. Some projects require a moisture barrier or primer for timber subfloors, and compatible tile adhesives must be used. Temperature and humidity management during curing reduces cracking risk.

In standards practice, zandcementanhydrietscreed is treated as a cementitious screed type and is subject to regional building codes and testing for bond, wear, and moisture transmission. Its environmental impact depends on cement content and transport; some formulations aim to minimize cement use while preserving performance.
