Product Description
FOX HISTOCRETE HORASAN is a ready-to-use decorative render mortar based on natural hydraulic lime, containing silica aggregate, inorganic mineral fibres (6 mm length) and natural brick dust, formulated without cement. With a grain size of 0–3 mm, the product can be applied by trowel at thicknesses of 3–10 mm. Compressive strength exceeds 15 kg/cm² after 7 days according to TS EN 196. Thanks to the homogeneously distributed inorganic mineral fibres, a continuous repair surface is achieved without shrinkage cracking. Its water-soluble salt-free composition makes it safe for use in the restoration of historic masonry structures. It is asbestos-free and environmentally friendly. Consumption is 1.7 kg/m² per 1 mm thickness, and the product is supplied in 20 kg polyethylene-reinforced kraft bags.
Key Benefits
- Long-lasting repair surfaces are achieved thanks to mineral fibre reinforcement that prevents shrinkage cracking.
- Its cement-free formula allows application without damaging historic masonry and stone structures.
- The absence of water-soluble salts minimises the risk of chemical damage in historic building restoration.
- Controlled production processes ensure consistent and homogeneous mortar quality on every project.
- Wide range of applications; a single product suitable for interior and exterior rendering, joint repair, surface repair and historic building restoration.
- Its asbestos-free, environmentally friendly composition protects the health of users and the environment.
Advantages
- Thanks to specially selected inorganic mineral fibres homogeneously distributed throughout the mix, a shrinkage-free mortar is obtained; a continuous repair surface is achieved on the applied substrate.
- The use of a ready-mixed mortar produced under continuous quality control ensures consistent product quality on every project; achieving mix homogeneity in site-prepared mortars is extremely difficult.
- FOX HISTOCRETE HORASAN render, which contains no water-soluble salts, is one of the best products that can be recommended for the restoration of historic masonry structures.
- Since brick dust has pozzolanic properties, it behaves in accordance with the traditional Horasan mortar mechanism.
- Asbestos-free and environmentally friendly.
Usage Areas
- Historic structures and locations where a historic building effect is desired (cisterns, water wells, aqueducts, bathhouse structures, etc.)
- Interior and exterior rendering
- Repair of existing renders
- Repair of natural stone and brick wall joints
- Surface repairs
Application Steps
- 1
Surface Preparation
Surfaces to be repaired and rendered must be sound, dust-free and clean. The surface must be free from foreign matter that would reduce adhesion, such as dirt, oil, grease, coatings and surface curing compounds. If water is running over the surface, it must be sealed with a suitable plugging mortar. The wall surface must be dampened before applying FOX HISTOCRETE HORASAN; however, there must be no free water (running water) present.

Mixing
Measure the appropriate quantity of clean water into a mixing bucket. Add FOX HISTOCRETE HORASAN gradually and mix with a mixer at 400–600 rpm for 3–4 minutes until a homogeneous, lump-free consistency is obtained. Allow to rest for approximately 4 minutes, then mix again for 30 seconds before use. Water ratio: 0.30–0.32 litres per 1 kg of powder; 6.0–6.4 litres per 20 kg bag.

Application
Apply the prepared mortar by trowel at a thickness of 3–10 mm. Allow the mortar to absorb water; then sprinkle water with a plastering brush and finish the surface with a steel or wooden float to the desired texture. In multi-coat applications, each layer must be 3–10 mm thick; the previous layer must be dampened before applying the next coat, and the new coat must be applied before the previous layer has fully hardened.

Curing and Protection
Large surfaces exposed to the atmosphere must be protected against rapid evaporation with hessian cloth or water for 24–48 hours after application in hot, dry or windy conditions. For exterior surface applications, the surface must be protected from sun, wind, rain and frost.
- 5
Tool Cleaning
Tools and equipment used must be cleaned with water after application. Once FOX HISTOCRETE HORASAN has hardened, it can only be removed from the surface by mechanical means.
Critical
During application, ambient and surface temperature must not fall below +5°C or exceed +35°C.
Critical
For the material to complete its set, ambient and substrate temperature must not drop below the permitted minimum temperature.
Critical
For exterior surface applications, the surface must be protected from sun, wind, rain and frost for the first 24–48 hours after application.
Important
The wall surface to which FOX HISTOCRETE HORASAN is to be applied must be pre-wetted to improve the adhesion and setting time of the mortar.
Important
There must be no free water on the surface that would impair adhesion; if water is running over the surface, it must be sealed with a suitable plugging mortar.
Important
In multi-coat applications, each layer must be 3–10 mm thick; the previous layer must be dampened before applying the next coat and the new coat must be applied before the previous layer has fully hardened.
Important
Once opened, the product must be stored under appropriate conditions and used within one week.
Important
The product must be stored in its original packaging, in a cool and dry environment, away from direct sunlight and protected from frost. For short-term storage, no more than 2 pallets should be stacked on top of each other.
Critical
Appropriate work clothing, protective gloves, goggles and a mask must be worn during application. Contact with skin and eyes must be avoided; in case of contact, wash thoroughly with plenty of water and soap. If swallowed, seek medical attention immediately.
Critical
It is dangerous to approach storage and application areas with open flames; areas must be ventilated.
Important
Food and beverages must not be brought into application areas. The product must be stored out of reach of children.
Information
The technical values above are given for +23°C and 50% relative humidity conditions. Higher temperatures shorten the setting/curing time; lower temperatures extend it.
