Lime renders were traditionally applied to give protection to walls built of poor quality rubble stone or porous brick or to walls in exposed locations facing driving winds. Rendering is the process of applying exterior renders such as a lime render or lime wash to exterior walls of a building.
Lime renders help by acting like a sponge, absorbing rainfall then allowing it to evaporate rather than soak into the wall. Most cottages and houses built of
rubble stone would have been rendered originally and they tend to suffer from penetrating damp if the lime render is removed or replaced with a cement rich render.
Traditionally
limewash was the principal finish applied to historic buildings, quite often applied directly to the masonry or brickwork and more commonly to lime render. As with all lime coatings,
limewash is a breathable coating allowing evaporation of moisture and water vapour.
Inter-Clean has completed numerous lime render projects including the Bishops Palace in Kilkenny, the new headquarters for the Heritage Council of Ireland (see display photos).
The application of lime render is a highly skilled craft something which is understood within Inter-Clean and hence only highly skilled craftsmen are employed to ensure a high quality finish.
