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.

Can a dehumidifier cause efflorescence?

In fact, if a dehumidifier is used in a basement with moisture problems, it may cause greater damage. By drying out the basement air, moisture is drawn into the basement more rapidly causing efflorescence and spalling of concrete and further damage to interior finishes.

How do I reduce efflorescence in my basement?

The best way to prevent efflorescence in basement concrete is to have the surface professionally sealed. There are a variety of coatings with different price points and roles to fill. Acrylic sealers are a lightweight option.

Can efflorescence be caused by humidity?

Efflorescence is often a seasonal problem, and humidity will impact whether soluble salts appear. It usually escalates in winter, since rain, snow, sleet and other inclement weather conditions may arise. However, efflorescence can still occur in spring, fall and summer.

Will a dehumidifier pull moisture from wall?

Dehumidifiers can help remove moisture from the air, which indirectly removes it from the walls, too. To speed up evaporation, remove molding and baseboards to prevent moisture from entering behind them.

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.

What can be done to prevent efflorescence?

To help prevent efflorescence, V-SEAL should be sprayed anywhere brick, mortar or cement will be exposed to water. For example, applying V-SEAL before any exterior below grade coating or elastomeric membrane, will aid and greatly retard any chance of efflorescence in the future.

Can efflorescence be avoided?

Clear water repellents, silicone and acrylic coatings are among the solutions often suggested for preventing efflorescence. A coating may prevent efflorescence from recurring by reducing the amount of water absorbed by an exposed masonry surface.

Is efflorescence in basement common?

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.
