Exterior Lime Stucco
Many historic stone houses were originally covered in stucco, also known as plaster or parging. This exterior plaster protected the masonry units and also kept the building less drafty. The lime stucco was then covered with a lime wash which further protected the plaster from deterioration. This system allowed for very economical wall finishes because they were both durable and repairable. Today, the fashion is to remove plaster from stone exteriors of historic buildings.
Traditional lime plaster is long lasting, flexible, and vapor permeable, which are characteristics not inherent to cement plaster. Lime plaster is carbon neutral, has high alkalinity, and resists moss, mold and other growths that can be found in cement-based plaster. While we will remove old parging from your stone house and repoint the stone with lime, we can also repair parging. We regularly remove cement and synthetic stucco from historic homes which was applied improperly and which often causes mold development within the home. Lime plaster is the solution in this situation. Finishes:
