Today we are going to discuss the definition of efflorescence. Efflorescence occurs when salt migrates to the surface of a porous material like concrete, brick, stone or stucco and forms a coating. Salt that is dissolved in water or another liquid solution will move to the porous surface and then evaporate which leaves a coating of salt. It sometimes travels through the masonry or other construction material and occasionally it is already in the material and the water penetrates and moves it to the surface. This crystalline deposit of salts may appear white or have a grayish tint and often sparkles a bit.

The word efflorescence means “to flower out” in French and in these cases it is salt flowering out of the surfaces. These are samples of primary efflorescence which causes staining. Sub-efflorescence, also known as spalling, is much more expensive to fix and we cover that issue in another episode. Cleaning of the surface is often temporary and not necessarily a cure for future recurrence.

Using a facade like Ceramitex is a way of avoiding the issue altogether. The sintered ceramic is not porous like many masonry materials and repels water from the surface.

Today we are going to talk about the definition and comparison of spalling. Spalling is the pitting, flaking, delaminating or cracks that appear in concrete or bricks when the temperature goes below freezing and the moisture trapped inside expands. It can even be caused by the embedded steel reinforcement bars corroding and causing stress on the surrounding concrete. Over the course of years this will worsen and could even lead to structural issues.

Spalling is not attractive and makes a building look unmaintained. It could potentially be hazardous as falling debris or trip hazards and the appearance lowers the value of the property.

Ceramitex – sintered ceramic facade system is a perfect choice for a durable exterior that won’t crack or delaminate as the sintering process of high heat and pressure doesn’t allow moisture to penetrate the surface. It is also graffiti, scratch and impact resistant.
