Understanding Concrete Efflorescence How It Results In Ugly Foundation Walls
At Permaseal, we respond to customer questions regarding concrete problems on a daily basis. One of the most frequent, and most perplexing for homeowners, is what they should do once they find layers of white, flaky deposits on their basement wall surfaces. This powder is very popular on concrete types of surface -- especially in basements and crawl spaces -- and it is called efflorescence.
What Causes Efflorescence?
Cement is a porous material -- and it has been since the day it dried. Because of this, it'll accept moisture from the earth outdoors, steadily releasing some of this moisture into your house. This really is most significant reasons that cellars are infamously damp, humid spaces.
As this moisture passes through your cement, it brings a small percentage of minerals from the earth outside in conjunction with it, along with the lime in the concrete itself. When it evaporates in your basement, it simply leaves these types of minerals behind. Over time, they create the white-colored, flaky powder that you notice on your wall surfaces today.
Cleaning up Efflorescence from Basement Walls
There are several products currently available which are exclusively aimed at removing unsightly stains from concrete walls and flooring surfaces. One good way to remove efflorescence should be to rent a power washer from a nearby home improvement store and to blend it with these kinds of chemicals to successfully blast efflorescence off the cement.
For a less expensive solution, however, you may substitute these custom made chemicals using a solution of chlorine bleach. Coupled with a power washer, pressure washer, or just by applying with a scrub broom and some work, you should be in the position to clean off the majority of efflorescence issues.
Phosphoric acid may also be used not only to eliminate efflorescence powder but also corrosion, grime, unsightly stains, and hard water build up. Even so, phosphoric acid, as well as other acids, should be used carefully and with great care.
Safeguarding Your Basement from Efflorescence
At Permaseal, we suggest protecting your concrete surfaces from efflorescence before a problem develops. Having said that, if you clean already affected cement, protection can be applied after.
Our recommended way to protect against efflorescence is by sealing your concrete walls with a concrete sealer. The product works deep in the pores of your concrete walls and floors to create a glass-like silicate bond in the concrete.
This barrier halts the movement of moisture through the basement walls and flooring surfaces, protecting your cellar from both efflorescence and also the water vapor transmission associated with basement moisture.
Concrete treatments can be applied as a spray, roller, paint brush, and also other ways, and it dries out in 2-4 hrs. It is harmless for indoor use as well as outdoor use, and can protect your basement in a lot of ways.
