This project in Darwen Nr Blackburn Lancashire involved Lime Rendering the rear elevation of this end terrace property. Our Team of Restoration Builders took 4 weeks to complete this project. The property had a cement based render on with a pebble dash finish. This was removed using small air tools. Due to the limited working space we took materials to the site daily.
The house was under renovation as we started the lime rendering work. The internal wall had damp patches & Black Mould Growth on the walls. Some of the plaster on the internal walls had blown, in other areas the salts in the gypsum plaster had been deposited on the surface.
Our Building team started the project by erecting an access to the external elevations. The existing cement based render & pointing was removed from the walls. Removing the existing cement render & mortar from the stone walls was done using small air tools, these avoid damaging the base stone masonry.
The cement render, unlike Lime render is not breathable. The moisture in the wall is trapped within the internal masonry. A Lime Based Render is fully breathable allowing any moisture Damp in the walls to escape.
Our Builders then packed & filled any voids in the rear elevation, using lime mortar, before applying 3 layers of lime render.
