This project arose due to extensive moisture ingress through the external walls. The house is positioned at the top of a hill adjacent to the Cliffs of Moher. Driving wind and rain is a common occurrence throughout the winter months in this location. Damp patches were evident on the walls internally.

There was a sand and cement render applied approximately twelve years ago both internally and externally. This plaster was removed. There was extensive soot leaching from one of the chimneys.

There was extensive rot to parts of the sash windows to the front elevation. The cills in particular had rotted. This was the result of poor detailing in the window and the cill. The windows to the front were removed and refurbished. A stone upstand was grafted onto the existing stone cill with a rebate cut into the wood cill on the window along with a drip. A linseed paint was applied to the windows.

We applied a scud coat, dubbing out coat, a scratch coat and a finish dash coat. The dash coat was machine applied. In the gable with the soot leaching we applied a lime mortar with the addition of cow dung to prevent the further leaching of soot.

A two layer sacrificial coat of a lime/silica sand was applied to the finish coat. This increased the resistance of the plaster against water ingress as well as being a decorative coat.

The plaster appears to have worked as it was intended with the internal walls are showing no sign of moisture following another wet winter.
