known for its versatile appearance, ready availability, and durability,
portland cement plaster remains a popular finish for many buildings,
from commercial to residential. However, damage can occur, whether
on older installations or poorly installed newer ones.
Moisture management is a top priority in a stucco installation
because water is one of the major culprits in plaster deterioration.
It can lead to rust and rot. It enters the building through cracks,
through the roof, around chimneys, or through window and door openings.
It can get behind building paper that is torn or not properly lapped
at seams. Portland cement plaster is a breathable material that
does allow moisture vapor to pass through, so it is capable of drying
out and does not trap moisture.
any case, repair is a straightforward procedure that can bring the
surface back to good condition.
