Why Not Paint Concrete?
Applying parging to foundation walls helps to provide a first layer of defense against the exterior elements. Yes, parging will break down over time because concrete does not have an unlimited lifespan, but a properly applied parge coat will last for a very long time.
What is Concrete Spalling?
Spalling is a condition that refers to concrete that has become pitted or flaked. The cause is nearly always environmental factors like a non-porous material, or a poor mix at the time of installation. While the result can be just a cosmetic issue, if left unchecked, spalling can also lead to structural damage.
