Cracks allow both liquid water and vapor to penetrate the adobe beneath, and the stucco prevents the wall from drying. As a result, porous mortar remains, and rather than acting as a dense barrier against water penetration, it now acts as a wick, drawing water in during a rain storm but also wicking in humidity year-round. It is a common error to assume that mortar hardness or strength is a measure of its suitability in adobe repair or reconstruction.

After the damage bricks are out, the area needs to be thoroughly cleaned of any remaining moisture, dust or dirt. Consequently, it makes the mortar more sandy over time, exponentially increasing the mortar’s ability to absorb water. 43 Historic Structure Reports Traditional adobe construction techniques in North America have not varied widely for over 3-1/2 centuries.
