Strengthening of mortar joints in solid brick masonry.

Structure type

Load-bearing external or spine walls in solid brick.

Detail

Strengthening of the mortar joints, with or without reinforcement.

Application cycle

1. Solid brick wall.
2. Raking out the masonry joints to a depth of 2-3 cm, then replacing the removed bedding mortar with RALLK Muro K class M15 or RALLK Muro K 02 class M10 structural mortar based on NHL 3.5 natural hydraulic lime. Depending on the strengthening design, reinforcing elements may be embedded in the repointing mortar.
3. 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.
4. 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 joints are 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 strengthening mortar or skim coat to the substrate.
2. See the individual product data sheets for application methods and precautions.
