Rehabilitación Vivienda Margenat

SpainSpainCompany Name: CLARA CADAFALCH

Project description

With the rehabilitation of the staircase in this impressive housing located Barcelona center, the accessibility has been sought improving the connexion between the different floors and giving a key ornamental design to the building.
Plaster craftmanship was the inner secret to conclude this remarkable piece of art.
The plaster handrail and the railing have been executed “in situ” due to the geometric complexity of the stair, resolved with Iberyola®, a highly fine plaster that allows a finish of high whiteness and perfection.

For this, they were carried out for each section of the handrail rubber moldings, gutta molds were placed and it was filled with plaster and esparto grass to make the negative. This was the process to follow in the whole development of the handrail.

Every section was recalculated in situ, in order to achieve the best curve radius for the design and use of the handrail.

In this renovation, Placostic® renewal 1h has been used for the plastered curved ceilings, in combination with Mecafino® Plus and Proyal® XXI providing an excellent finish and aesthetic, with an extra comfort.

For rest of continuous ceilings in other areas such as corridors and living room and dinning rooms, 4PRO® was selected to assure a correct planimetry and smooth finish, a key point due to the amount of natural lightning of the house.
