{"title":"Wall Repair","description":"\u003cp\u003eRepairing old masonry is not done according to the same principles as concrete repair. Brick, stone, adobe, and lime-based structures are made from materials with different chemical compositions, elasticity, and vapor permeability — the repair material used must be compatible with the original material. One of the most common mistakes in renovation work is pressing cement mortar into old lime-based masonry.\u003c\/p\u003e\n\n\u003ch3\u003eWhy is compatibility important?\u003c\/h3\u003e\n\u003cp\u003eIf the repair material is harder than the surrounding masonry, stress concentrates in the weaker material — the original masonry — causing it to crack. This is especially true for old brick and stone masonry, where the original mortar is lime-based and soft, making modern Portland cement-based repair mortar incompatible.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible materials for the original masonry\u003c\/h3\u003e\n\u003cp\u003eNHL lime-based repair mortar is a natural hydraulic lime-based, breathable, vapor-permeable, and compatible material for brick, stone, and adobe masonry. For historic buildings and heritage masonry, this is the only suitable repair material — WTA-compatible. Cement-based masonry repair is suitable for modern brick and block masonry where the original material is also cement-based. Repairing adobe structures should only be done with adobe- or clay-based materials: cement-based repair materials pressed into adobe will detach over time due to moisture movement in the adobe.\u003c\/p\u003e\n\n\u003ch3\u003eWhat types of masonry damage can be repaired?\u003c\/h3\u003e\n\u003cp\u003eFor cracks, the width and depth of the crack determine the repair method. Hairline cracks can be treated with surface material; structural cracks must be stabilized by injection. For stone spalling and material loss, cleaning the damaged area and regularly applying a primer and repair mortar compatible with the original material is necessary. For missing joints, removing old, crumbling joints and repointing with compatible material is critical — especially for outdoor stone and brick masonry, where the joint is the primary barrier against water penetration.\u003c\/p\u003e\n\n\u003cp\u003eBrowse our masonry repair materials or request advice to assemble a compatible repair system suited to the type and age of your masonry.\u003c\/p\u003e","products":[{"product_id":"kerakoll-geocalce-f-antisismico","title":"Kerakoll GeoCalce F Antisismico","description":"\u003cp\u003eFine-grained, breathable structural geo-mortar made of pure natural NHL lime and geo-binder - class M15.
