Using Breathable Brick and Stone Repair
Using Breathable Brick and Stone Repair
Breathable stone repair is a vital technique in preserving the integrity and aesthetic of masonry structures. This approach is particularly important for historical and older buildings, where cement based repair methods may inadvertently trap moisture, leading to further deterioration.
Older buildings were often built without a damp proof course, no cavity or a rubble filled cavity. This type of structure means moisture can pass both up and through the walls. However the use of lime mortar, lime plaster and breathable paints allowed the free movement of this water vapour, allowing water in the walls to evaporate out.
Cement mortar, gypsum plaster and synthetic paints do not allow the same free movement of moisture so trapping water in the walls. Over time through freeze-thaw cycles, the stone and brick will start to effloresce, laminate and spall.
Using a breathable stone repair promotes the durability of the structure, maintains the health of masonry and respects the historical significance of the materials involved. This method stands out as a responsible and effective solution for heritage conservation, ensuring that these architectural treasures remain resilient and visually appealing for future generations.
Womersley's brick and stone repair mortar is a blend of natural minerals and aggregates in a natural hydraulic lime binder. These materials allow the natural evaporation of moisture but have a good structural strength and bond to the substrate. It contains absolutely no cement.
Womersley’s brick and stone repair mortar can be carved, sanded, dressed and shaped like stone or brick to give a uniquely convincing look and feel. Manufactured on site from Lime Green Contour mortar and Colour Blaze natural mineral pigments.
