Crack repair using the “cuci-scuci” technique (stitching by local brick replacement) on solid brick masonry.

Structure type

Load-bearing or infill external walls, or partitions, in solid brick.

Detail

Local removal and relaying of bricks along a crack.

Application cycle

1. Standard interior or exterior plaster.
2. Solid brick wall.
3. Local dismantling and rebuilding of the bricks along a structural crack in the wall, to restore continuity, strength and even load distribution, carried out with RALLK Muro K structural mortar based on NHL 3.5 natural hydraulic lime.
4. Thin patching and/or leveling skim coat over the existing plaster with RALLK Rasante K nhl, based on NHL 3.5 natural hydraulic lime, to restore a flat surface, or alternatively a thicker plaster coat of RALLK Muro K.
5. Troweled interior or exterior finish with RALLK Marmo K, applied with a steel float and polished with a flexible steel spatula until the surface is even, smooth and silky, or has another desired look (or finish with a finishing coat, powder mineral finish, acrylic, siloxane, lime or silicate paste finish, or lime, siloxane, acrylic or silicate paint, as set out in the specifications).

Additional information

1. Check that the masonry is sound and clean, and free of dust, loose parts, demolition debris, soot, mold, salt efflorescence, other organic material, grease or anything else that could impair the bond of the skim coat to the substrate.
2. See the individual product data sheets for application methods and precautions.
