Just a few examples of classif efflorescence patterns in older brick buildings.
A classic efflorescence pattern, at least around here, and seen in older and new brick and brick veneer houses. Water entering through the stone window sill and draining into the brick below. Caused by lack of flashing under the stone sill. A quick and inexpensive fix is to seal the sill with a 50 / 50 mixture of linseed oil and terpentine.
Water entering through the stone trim.
Self-imposed water intrusion with a classic efflorescence pattern (radiating down and outward). Sometimes, the owner puts the gun in their own mouth, wouldn’t you say? Source of the water? :mrgreen:
Hope this helps;
