Remediating Efflorescence: You could use common household items like a dry, coarse brush or diluted vinegar to remove it. Some people prefer to use a power washer. Typically, this is only recommended for outdoor surfaces, as the sun can dry it more quickly.
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.
How do you keep moisture out of concrete walls?
Plastic drainage mats, or dimple mats, allow air to circulate under the flooring and provide a moisture barrier. They also provide an insulating layer of air that separates the floor from cold concrete, reducing the potential for moisture damage from condensation or water vapor migrating through the concrete.
Will Drylock prevent efflorescence?
A. United Gilsonite Laboratories manufactures a product called DRYLOK® Etch. While DRYLOK® Etch will remove efflorescence and help prevent it from reoccurring, understand that efflorescence comes from salt deposits found in the block itself and can reoccur at any time.
How do you stop condensation on basement walls?
Insulate Your Basement: Insulating the places where condensation builds up can also help to eliminate moisture. Covering those places, such as walls, pipes, and ducts, with insulation, will help keep warm air from coming in contact with the cool surfaces, thus preventing condensation.
Will a dehumidifier get rid of 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.
Is efflorescence a serious problem?
Ultimately, efflorescence itself isn’t dangerous. However, it can lead to potential moisture problems that can cause structural damage to building materials. That means if you find efflorescence in the basement or on concrete and other structures, it’s important to take action.
Should you put a vapor barrier on basement walls?
Building codes usually require a vapor barrier (4 mil plastic sheeting) on exterior basement walls if the framing is attached to masonry or concrete surfaces, or if the wood framing butts up against the outer basement walls.
