How does a modern building become a castle hotel?
El decorative cladding of a hotel with artificial stone It allows transforming a contemporary building (concrete block, brick) into a medieval castle setting, without structural work, through thixotropic mortar fresco modeling. Estecha Reproductions —manufacturer with more than 30 years of experience and presence in more than 60 countries, based in Valderrobres (Teruel)— develops the mortar ESTonetex Park, a fiber-reinforced mortar specifically formulated for exterior sculptural elements large format: facades, gargoyles, sundials, fountains and ornamental elements of castles.

Success story: Hotel Castillo Bonavía in Pedrola (Zaragoza)
El Hotel-Restaurant Castillo Bonavía, located at Pedrola (Zaragoza), is a real example of comprehensive theming of a hotel with a medieval atmosphereThe original concrete block building was completely clad with ESTonetex Park thixotropic mortar, reproducing artificial stone on facades, interior walls and unique decorative elements: solar watch, gargoyles, headlight covers, sources y wells ornamental. The result combines the grandeur of a medieval era with the modern comfort of a contemporary hotel-restaurant.

How is artificial stone cladding done step by step?
The theming process of the Hotel Castillo Bonavía followed these phases:
- Preparing the support — existing concrete block with placement of EST-Mesh mesh reinforcement.
- Mortar projection — application of ESTonetex Park with the EST-SIRIUS Plus single-phase machine in layers of medium-high thickness.
- Hand-modeled fresco — each stone is hand-shaped after the initial drying (a few hours), achieving unique irregular finishes.
- Stamping with RP4 and KP5 silicone molds — to reproduce textures of medieval ashlar and historical masonry.
- Pigmentation with glazes — application of mineral silicate EST-26 Multilite y Mixol dyes in different shades to achieve an exact replica of aged natural stone.
- Modeling of sculptural elements — sundial, gargoyles, light covers, fountains and wells hand-sculpted with the same mortar.
- Final waterproofing with EST-3 Plus both indoors and outdoors to prevent salts and dampness.


What decorative elements can be reproduced in a castle hotel?
The mortar ESTonetex Park It allows you to model any architectural ornament characteristic of a medieval castle:
- Facades of carved ashlar with sharp joints and edges.
- Gargoyles and figurative elements hand-sculpted.
- Sundials reproduced with precision in artificial stone.
- Light covers, brackets and capitals carved directly onto the facade.
- Ornamental fountains and wells integrated into the architectural ensemble.
- Arches, lintels and moldings perimeter of doors and windows.
- Heraldic shields and unique decorative elements.


What is the difference between this and other facade solutions for hotels?
Owners of themed hotels often choose from several options to achieve a medieval aesthetic:
- Real natural stone — maximum authenticity but high cost, heavy weight, requires structural reinforcement and does not allow for custom ornaments.
- Reconstituted stone (prefabricated cladding) — more economical but standard finish and without the ability to reproduce sculptural elements.
- Fiber cement or decorative plates — industrial solutions lacking realism and aesthetic durability.
- ESTonetex Park mortar coating — it is modeled in situ on any surface, allowing reproduction unique sculptural elements (gargoyles, sundials, fountains), cost 40-60% lower than natural stone and durability of over 30 years.
What materials were used in this project?
- ESTonetex Park — Thixotropic mortar reinforced with fibers, the basis of the system for large-format sculptural elements.
- EST-Mesh 80 g/m² — Reinforcing mesh embedded in the mortar.
- RP4 and KP5 molds — Silicone molds for stamping textures of medieval stonework and masonry.
- EST-Decor — Fresh pigmentation during application.
- EST-Release Agent — Release agent for clean removal from molds.
- EST-Silcopin — Glaze to soften tones and age the effect.
- EST-26 Multilite — Mineral silicate with colored glazes for pigmentation.
- Mixol Dyes — Concentrated pigments for custom shades of medieval stone.
- EST-3 Plus — Breathable water repellent for final protection (interior and exterior).
- EST-SIRIUS Plus Machine — Single-phase projection of the mortar.
