Gypsum Mortar (DOVA-801)
Gypsum Mortar DOVA-801 is a versatile interior building material made from calcined gypsum, sand and water — used interchangeably with gypsum plaster for paint-ready walls, decorative work, historic restoration and fireproofing.
Composition & Chemistry
The core of gypsum mortar is the mineral gypsum (CaSO₄·2H₂O). Calcination heats raw gypsum to about 150 °C, removing most of its water to create Plaster of Paris (CaSO₄·½H₂O). On rehydration with water and sand, needle-like crystals interlock to form a solid, hard mass.
Applications
Interior Walls & Ceilings
Provides a paint-ready surface without the extra putty layers required by cement.
Decorative Work
Captures fine detail and does not shrink — the standard for cornices, mouldings and ceiling roses.
Historic Restoration
Essential for older masonry, where rigid cement mortar would damage the original soft bricks.
Fireproofing
Coats structural elements — it releases steam when exposed to fire, cooling the structure.
