The cycle of freezing followed by hot and sunny days is an ideal way to
inflict damage on the protective paints, varnishes and sprays designed
to protect building materials. Frequently we see buildings beginning to
flake as the city starts to warm up. In these situations, frost or ice
has penetrated microscopic flaws in the protective sealant and caused
separation between that surface and the underlying structure.
If left unchecked the paint or varnish will start to flake and then peel
from the building, exposing the core frame to the elements and
gradually weakening the entire building.
