Should I worry about efflorescence?

Efflorescence itself isn't dangerous or harmful. It can lead to potential moisture problems that can cause structural damage to building materials. So it is important to take action when you notice efflorescence in your basement, on your paving stones, or on other structures.

Is efflorescence a problem?

Efflorescence alone does not pose a major problem, but it can be an indication of moisture intrusion, which may compromise the structural material. Building materials, such as concrete, wood, brick and stone, are porous materials. Porous materials can absorb or wick water by a process called capillary action.

Is efflorescence a big deal?

When you observe efflorescence, it's an indication of moisture migrating through the concrete, brick or stone. In general efflorescence is not considered to be a major concern when observed around a home; however, there are a few instances when efflorescence can be serious and a warning sign of a problem.

Does efflorescence go away by itself?

Yes. Although efflorescence will eventually go away naturally, there are commercial cleaners available that are specifically formulated to remove efflorescence from the surface of the concrete pavers.

Does efflorescence mean water damage?

When efflorescence happens, it can indicate a moisture issue that could potentially damage the structure. When water reaches a building material's surface, evaporation will occur. After the water evaporates, salt is left behind, but water absorption and wicking continue.

All about efflorescence and how to avoid

Is efflorescence a building defect?

Efflorescence is the formation of insoluble salts that appear as white coloured staining on tiles, concrete, brickwork and stone and is generally considered as a building defect.

Will a dehumidifier prevent efflorescence?

The truth is that a dehumidifier does nothing to counter or reverse the effects of efflorescence on your crawl space walls. This device will only help you dry out the crawl space air so moisture won't build up and cause condensation, mold growth, rust, and other problems.

Does efflorescence worsen?

One, continued efflorescence can eventually lead to degradation of the materials, so you need to keep an eye out for signs of foundation problems. And secondly, the increase in moisture from water traveling through the walls can cause - wait for it - mold!

How much does it cost to remove efflorescence?

A handyman or house cleaning service will charge $143 to remove efflorescence from a 150-square-foot area, which includes the labor and material. You can remove the substance for $20, the cost of a clear water sealer, and save 86 percent.

How do I permanently remove efflorescence?

Spray a solution of vinegar and water on the brick and scrub it with a brush. Mix equal parts of water and white vinegar in a spray bottle. Spray the solution onto the surface and let it sit for 5 minutes. Then, spray the bricks with the mixture again and use a stiff brush to scrub away the efflorescence.

Does efflorescence mean the basement leaks?

Does Efflorescence Mean the Basement Has a Leak? Efflorescence requires the appearance of water from somewhere in the basement. Most commonly, this water does come from a leak, typically through cracks in the walls or floor. However, you might also have an internal leak through your plumbing system.

Can I paint over efflorescence?

Any efflorescence on the surface must be removed prior to painting as it is regarded as a poor and friable base that prevents paints and coating systems from adhering effectively.

Is efflorescence common in basements?

Efflorescence is a common problem in concrete and masonry block foundations. The white fuzzy stuff you see along the inside and outside of your basement wall is efflorescence.

Why does efflorescence keep coming back?

If your wall started out with only a small amount of water-soluble salts within it, the efflorescence might stay away on its own after one cleaning, or only lightly return. But if you wall has a high salt content, the efflorescence could develop again and again.

How long does it take for efflorescence to appear?

These efflorescent salt deposits tend to appear at the worst times, usually about a month after the building is constructed, and sometimes as long as a year after completion. Required Conditions: Efflorescence is not a simple subject. Three conditions must exist before efflorescence will occur.

Is efflorescence harmful to breathe?

Unlike mold, efflorescence isn't normally harmful to human health, but it can cause mild irritation if inhaled or if it comes in contact with the eyes. Even so, efflorescence doesn't usually float freely in the air as dust. Pressurized water can dissolve efflorescence and clean away the mineral deposits.

Will a pressure washer remove efflorescence?

Pressure washing can work to remove white efflorescence once the surface has thoroughly dried. The surface must be thoroughly rinsed to ensure that no residue remains. We also use a safe detergent to ensure a thorough clean.

Why does my new concrete have white spots?

White stains or a white powdery coating on new concrete is not uncommon. Such discoloration, known as efflorescence, is caused by salts that are brought to the surface of new concrete by the natural curing process.

Why are my bricks turning white?

The white residue is triggered by efflorescence or salt petering. Efflorescence or salt petering is a crystalline, salty deposit with a white or off-white colour that can form on the surfaces of bricks, masonry or concrete.

How long does it take for efflorescence to fade on concrete?

Over time, efflorescence will eventually wear away or disappear, usually within 3-6 months, although it can take much longer depending on the circumstances.

Who is responsible for efflorescence?

Recommendations for mortar are contained in Technical Notes 8 and 8B. Cement. The principal contributor to efflorescence in mortar and grout is the alkali content of portland cement. The tendency of cement to effloresce may be predicted with reasonable accuracy from a chemical analysis of the cement.

Can efflorescence cause mold?

Therefore, if efflorescence is present, there is a significant chance of mold growth or other moisture issues may be present. For example, while efflorescence on a garage floor will not cause a problem, the accompanying moisture can cause mold growth on items stored on the floor.

What percent of basements leak?

Over 60 percent of homes have a leaking basement. Wet basements tend to be one of the most frequent complaints of homeowners.

How do I prevent efflorescence in my basement?

Preventing Efflorescence

Applying a hydrophobic sealant to a wall, floor, or ceiling will prevent the water from soaking into the building material. The water will remain on the surface of the sealant and will dry on top of it instead of against the actual wall itself.

What is the white fuzzy stuff growing on my basement walls?

It can be just a white powder on your concrete, salt-like crystals, white fuzzy stuff, or what looks like white stalactites growing on your concrete wall. These white deposits happen when water is drawn out of a cementious material: it is called efflorescence. It is a scientific reaction.
