Terrae Khorasan plaster is inspired by the traditional Khorasan plaster also known as Roman Plaster (itself derived from the ancient Greek binary cement). These are hydraulic plasters based on lime and added pozzolanic compounds (powdered lava rock or ceramics).
Terrae Khorasan plaster is a colored finishing plaster of medium granulometry (maximum particle size 1.4mm) negating the need for painting or other finishes.
The composition of Terrae Khorasan finishing plaster is based on natural raw materials like lime, metal oxides and various colored marble, quartz, ceramics and lava particles.
Suitable for green building and bioclimatic design.
The end result of the finishing is not of a solid uniform color like plastic paints or synthetic colored plasters. Instead it has a natural distinctive finish with a wide color gradient giving depth and character.
It is highly responsive to various application technique giving a wide range of finishes. The distinctive character of Terrae Khorasan Plaster is equally suitable in traditional applications as well as modern designs.
Terrae Khorasan finishing plaster is highly breathable material, regulating indoor moisture levels, improving indoor air quality. Naturally bacteriostatic and fungistatic.
Cost efficient solution due to eliminating the need for painting and the high maintenance costs associated with painting.
Highly durable even in adverse conditions such as in coastal areas. Suitable for pointing rock masonry.
In outdoors applications Khorasan develops a patina over time which is considered part of the charm of the material. In case that is not desired a sealer must be applied.
0% volatile organic compounds.
Terrae is about green buidling.

The substrate must be clean, fully cured, solid and sound, uniform and homogeneous.
Prior to application we thoroughly wet the substrate.
Comes in sets of 4 bags (3 bags of inert material and one binder).
Mix only whole sets.
Add 16 liters of water in a container and gradually add the bags mixing with a mortar mixer.
Add water if required and mix until a uniform paste is achieved.
Use a trowel or other appropriate tool for initial layering ,leveling with a float and finishing with a soft sponge float if a very smooth finish is required. It can also be burnished and polished, chiseled (after one day of curing) and numerous other ways.
Discreet surfaces must be applied uninterrupted to avoid visible joints, always finishing on the edges of intersecting surfaces.
For the first 24 ours after initial application keep surfaces damp with light uniform sprinkling. Quick drying must be avoided as with all plasters when curing.
Wash tools with water.
