Being familiar with Concrete Efflorescence How It Leads To Unsightly Foundation Walls
At Permaseal, we respond to client queries about concrete issues on a daily basis. Probably the most popular, and most perplexing for home owners, is what they ought to do once they find layers of white-colored, flaky deposits on their cellar walls. This kind of powder is very common on concrete types of surface -- specifically in basements and crawl spaces -- and is known as efflorescence.
What May Cause Efflorescence?
Concrete is a porous material -- and it has been since the day it dried up. For this reason, it will accept moisture from the soil outside, slowly releasing some of this moisture into your house. This really is one of the primary reasons that basements are notoriously moist, humid areas.
As this moisture moves through your cement, it brings a small percentage of minerals from the earth outdoors in conjunction with it, along with the lime in the cement itself. When it evaporates into your basement, it simply leaves these types of minerals behind. Over time, they create the white-colored, flaky dust that you notice on your wall surfaces today.
Cleaning up Efflorescence from Basement Walls
There are many products on the market today which are especially intended for getting rid of unsightly stains from cement walls and flooring surfaces. One good way to remove efflorescence would be to rent a power washer from a nearby hardware store and to combine it with these kinds of chemicals to successfully blast efflorescence away from the concrete.
For a more economical solution, however, you could substitute these custom made chemical substances with a solution of bleach. Combined with a power washer, pressure washer, or just by applying with a scrub brush and some work, you ought to be in the position to clean off the majority of efflorescence problems.
Phosphoric acid can also be used not only to eliminate efflorescence powder but also rust, grime, stains, and hard water build up. However, phosphoric acid, along with other acids, must be used carefully and with great attention.
Protecting Your Basement from Efflorescence
At Permaseal, we suggest protecting your concrete surfaces from efflorescence before an issue comes up. Having said that, if you thoroughly clean already affected concrete, protection can be applied afterward.
