Being familiar with Concrete Efflorescence How It Results In Ugly Foundation Walls
At Permaseal, we all answer client questions on concrete problems daily. Probably the most popular, and most puzzling for homeowners, is what they should do after they find layers of white-colored, flaky deposits on their basement walls. This particular powder is very popular on cement surfaces -- particularly in cellars and crawl spaces -- and is referred to as efflorescence.
What Causes Efflorescence?
Concrete is a permeable material -- and it has been since the day it dried up. Because of this, it'll accept moisture from the dirt outdoors, gradually releasing some of this moisture into your home. This really is most significant reasons that basements are notoriously moist, humid spaces.
As this moisture passes through your cement, it brings a small portion of minerals from the soil outdoors in conjunction with it, combined with the lime in the concrete itself. When it evaporates in your basement, it leaves these minerals behind. Over time, they create the white, flaky dust that you observe on your wall surfaces right now.
Cleaning up Efflorescence from Basement Walls
There are several products currently available which are specifically geared towards removing stains from concrete walls and flooring surfaces. One good way to get rid of efflorescence is usually to rent a pressure washer from a local hardware store and to blend it with these types of chemicals to successfully blast efflorescence away from the concrete.
For a more economical solution, however, you may substitute these customized chemical substances with a solution of bleach. Combined with a power washer, pressure washer, or simply by applying with a scrub brush and some hard work, you should be in the position to clean off the majority of efflorescence challenges.
Phosphoric acid could also be used not only to get rid of efflorescence powder but also rust, grime, stains, and hard water deposits. Even so, phosphoric acid, as well as other acids, should be used cautiously and with great attention.
Safeguarding Your Basement from Efflorescence
At Permaseal, we recommend protecting your cement types of surface from efflorescence before a problem comes up. However, if you thoroughly clean already affected cement, protection can be applied after.
Our recommended way to avoid efflorescence is by sealing your cement walls with a concrete sealer. The product works deep into the pores of your cement walls and floor surfaces to create a glass-like silicate bond in the cement.
This barrier puts a stop to the movement of moisture through the basement walls and flooring surfaces, protecting your basement from both efflorescence and 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 hrs. It's harmless for indoor use in addition to external use, and can protect your basement in many different ways.
