Mosaico Hidráulico Artesanal Barragán
The mosaics manufactured at Mosaicos Hidráulicos Barragán are done as they were done in the olden days, in an artisanal way, using materials of the highest quality. This enables the mosaics to be resistant to the passing of time and for them to be able to adapt to the designs required by the client.
The materials they use are basically: cement, sand, water, marble powder and pigments.
For the manufacture of these products they make use of different utensils, tools and machinery, being the main one a mould consisting of a base, a middle piece, and a stopper, where the materials which are used are poured into. This mould must be perfectly clean and be sufficiently resistant to bear the pressure which the hydraulic press exerts on it. They also use trepas (moulds), ladles and brushes.
The process starts by first placing the trepa (mould) with the chosen design. Then, the coloured mixtures are poured over the different compartments of the mould, creating the motive which has previously been selected. After that, the drying mortar is spread out and the mould is filled with the remaining mortar and pressed. Once the piece is removed from its mould, the next step is its setting. For this aim, the piece will spend around 20 days under water.
