Being familiar with Concrete Efflorescence How It Leads To Unsightly Foundation Walls
At Permaseal, we all respond to customer questions about concrete problems each day. One of the most frequent, and most perplexing for homeowners, is what they ought to do when they find layers of white, flaky deposits on their basement walls. This kind of powder is very popular on concrete surfaces -- especially in cellars and crawl spaces -- and is often known as efflorescence.
What Causes Efflorescence?
Cement is a permeable material -- and it has been since the day it dried. Because of this, it'll take moisture from the ground outdoors, gradually releasing some of this moisture into your house. This is one of the primary reasons that basements are notoriously damp, humid areas.
As this moisture moves through your concrete, it brings a little percentage of minerals from the soil outside in conjunction with it, along with the lime in the cement itself. When it evaporates into your basement, it simply leaves these minerals behind. Over time, they create the white-colored, flaky powder that you find on your wall surfaces today.
Cleaning Efflorescence from Basement Walls
There are many products on the market today which are exclusively intended for getting rid of stains from cement walls and flooring. One good way to remove efflorescence will be to rent a pressure washer from a nearby home improvement store and to combine it with these types of chemicals to successfully blast efflorescence off the concrete.
For a more economical solution, however, you could substitute these customized chemical substances with a solution of chlorine bleach. Coupled with a power washer, pressure washer, or simply by applying with a scrub brush and some hard work, you will be in the position to thoroughly clean off the majority of efflorescence problems.
Phosphoric acid may also be used not only to remove efflorescence powder but also rust, grime, stains, and hard water deposits. However, phosphoric acid, as well as other acids, must be used cautiously and with great attention.
Shielding Your Basement from Efflorescence
At Permaseal, we suggest protecting your cement surfaces from efflorescence before a problem develops. Having said that, if you thoroughly clean already damaged concrete, protection can be applied afterward.
Our encouraged way to prevent efflorescence is by sealing your concrete walls with a cement sealer. This product works deep in the pores of your concrete walls and flooring to create a glass-like silicate bond in the cement.
This barrier prevents the movement of moisture through the basement walls and flooring surfaces, protecting your cellar from both efflorescence and also the water vapor transmission linked to basement moisture.
Concrete treatments can be applied as a spray, roller, paint brush, or other ways, and it cures in 2-4 hours. It's safe for inside use as well as outdoor use, and may protect your basement in a lot of ways.
