Being familiar with Concrete Efflorescence How It Results In Ugly Foundation Walls
At Permaseal, we answer client questions about concrete problems every day. One of the most frequent, and most puzzling for property owners, is what they ought to do when they find layers of white, flaky residue on their basement walls. This powder is very common on concrete surfaces -- specifically in cellars and crawl spaces -- and is known as efflorescence.
What Causes Efflorescence?
Concrete is a porous material -- and it has been since the day it dried up. Because of this, it's going to accept moisture from the dirt outside, gradually releasing some of this moisture into your dwelling. This is most significant reasons that basements are notoriously damp, humid areas.
As this moisture moves through your cement, it brings a little percentage of minerals from the soil outside along with it, along with the lime in the cement itself. When it evaporates into your basement, it leaves these kinds of minerals behind. Over time, they create the white, flaky powder that you observe on your walls today.
Cleaning Efflorescence from Basement Walls
There are several products currently available that are especially designed for getting rid of stains from concrete wall surfaces and flooring. One great way to remove efflorescence would be to rent a power washer from a local hardware store and to combine it with these kinds of chemicals to effectively blast efflorescence away from the concrete.
For a more economical solution, however, you may substitute these custom made chemicals using a solution of bleach. Coupled with a power washer, pressure washer, or just by applying with a scrub brush and some hard work, you should be able to clean off the majority of efflorescence issues.
Phosphoric acid can also be used to not only remove efflorescence powder but also rust, grime, unsightly stains, and hard water deposits. Even so, phosphoric acid, along with other acids, must be used cautiously and with great care.
Shielding Your Basement from Efflorescence
At Permaseal, we recommend protecting your concrete types of surface from efflorescence before a problem arises. Having said that, if you thoroughly clean already damaged cement, protection can be applied afterward.
Our encouraged way to avoid efflorescence is by sealing your concrete walls with a cement sealer. The 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 halts the movement of moisture through the basement walls and floors, protecting your basement 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 cures in 2-4 hrs. It is harmless for inside use as well as external use, and may protect your basement in a lot of ways.
