What is Efflorescence?

Efflorescence comes from a French word meaning “to flower out.” In chemistry, and in the real world, efflorescence is the loss of water (or a solvent) of crystallization from a hydrated or solvated salt to the atmosphere on exposure to air.

Where does it happen?

While efflorescence can occur in natural settings it is most commonly seen on built structures. It is especially visible on porous materials like brick. If you do not know what efflorescence is, you may think that it is purely cosmetic. It will appear as a chalky residue on the outside of the brick structure.

What causes efflorescence?

Simply put, if you see efflorescence you have water intrusion. Once water penetrates the brick it will “flower out,” (remember the French definition?) Once water has entered your structure it will freeze and expand causes the integrity of the structure to come into question

What can you do to protect against efflorescence?

Although brick is very durable, extreme weather can have an adverse effect on it over time. Waterproofing your brick/veneer structure will help ensure that your brick work lasts as long as possible. Your brick and your home can benefit tremendously from waterproofing.

“Most sealants are made with siloxane, which chemically bonds to the material and prevents water from passing through it. This type of brick waterproofing sealant is clear, so it does not change the appearance of the building. In fact, rather than staying on the surface of the structure, brick sealant penetrates the material. It will need to be reapplied to older brick structures about every four to seven years, and newer buildings approximately every five to ten years.”
