Understanding Concrete Efflorescence How It Results In Unsightly Foundation Walls

At Permaseal, we all respond to customer questions about concrete issues daily. Probably the most frequent, and most perplexing for property owners, is what they should do once they find layers of white-colored, flaky deposits on their basement walls. This kind of powder is very common on concrete surfaces -- especially in basements and crawl spaces -- and it is generally known as efflorescence.

What Causes Efflorescence?

Concrete is a permeable material -- and it has been since the day it dried up. For this reason, it is going to accept moisture from the dirt outside, steadily releasing some of this moisture into your house. This really is most significant reasons that cellars are notoriously moist, humid spaces.

As this moisture moves through your concrete, it brings a little portion of minerals from the soil outside the house along with it, along with the lime in the concrete itself. When it evaporates into your basement, it leaves these kinds of minerals behind. With time, they create the white-colored, flaky dust that you find on your walls right now.

Washing Efflorescence from Basement Walls

There are many products currently available which are specifically aimed at removing stains from concrete wall surfaces and floors. One good way to remove efflorescence is usually to rent a pressure washer from a local hardware store and to combine it with these types of chemicals to successfully blast efflorescence off the cement.

For a less expensive solution, however, you could substitute these customized chemical substances with a solution of chlorine bleach. Coupled with a power washer, pressure washer, or just by applying with a scrub broom and some effort, you ought to be able to thoroughly clean off the majority of efflorescence problems.

Phosphoric acid can also be used not only to get rid of efflorescence powder but also corrosion, grime, stains, and hard water deposits. However, phosphoric acid, along with other acids, must be used carefully and with great care.

Shielding Your Basement from Efflorescence

At Permaseal, we suggest protecting your cement areas from efflorescence before an issue develops. However, if you clean already damaged cement, protection can be applied after.

Our suggested way to protect against efflorescence is by sealing your concrete walls with a cement sealer. This product works deep in the pores of your cement walls and floor surfaces to create a glass-like silicate bond in the concrete.

This barrier stops the movement of moisture through the basement walls and flooring surfaces, protecting your cellar from both efflorescence and also the water vapor transmission connected with basement moisture.

Concrete treatments can be applied as a spray, roller, paint brush, or other ways, and it dries out in 2-4 hours. It's safe for indoor use in addition to external use, and can protect your basement in several ways.
