Being familiar with Concrete Efflorescence How It Leads To Unsightly Foundation Walls
At Permaseal, we respond to client questions on concrete problems daily. Probably the most common, and most puzzling for homeowners, is exactly what they ought to do once they find layers of white-colored, flaky deposits on their basement wall surfaces. This particular powder is very common on concrete types of surface -- particularly in cellars and crawl spaces -- and is called efflorescence.
What May Cause Efflorescence?
Cement is a porous material -- and it has been since the day it dried. As a result, it'll take moisture from the dirt outside, steadily releasing some of this moisture into your home. This is most significant reasons that basements are infamously damp, humid spaces.
As this moisture moves through your cement, it brings a little portion of minerals from the earth outdoors in conjunction with it, along with the lime in the cement itself. When it evaporates into your cellar, it leaves these minerals behind. Over time, they create the white, flaky dust that you notice on your walls right now.
Cleaning up Efflorescence from Basement Walls
There are several products on the market today that are exclusively geared towards removing unsightly stains from concrete wall surfaces and flooring surfaces. One good way to get rid of efflorescence should be to rent a power washer from a nearby home improvement store and to combine it with these chemicals to successfully blast efflorescence off the concrete.
For a less expensive solution, however, you may substitute these customized chemical substances with a solution of bleach. Coupled with a power washer, pressure washer, or just by applying with a scrub brush and some work, you should be able to thoroughly clean off the majority of efflorescence issues.
Phosphoric acid could also be used to not only eliminate efflorescence powder but also corrosion, grime, stains, and hard water build up. However, phosphoric acid, along with other chemicals, should be used carefully and with great care.
Protecting Your Basement from Efflorescence
At Permaseal, we suggest protecting your concrete floors from efflorescence before a problem develops. However, if you clean already affected cement, protection can be applied after.
Our encouraged way to stop efflorescence is by sealing your concrete walls with a cement 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 halts the movement of moisture through the basement walls and flooring surfaces, protecting your cellar from both efflorescence and the water vapor transmission connected with basement moisture.
Concrete treatments can be applied as a spray, roller, paint brush, or any other ways, and it dries in 2-4 hrs. It's safe for indoor use in addition to external use, and may protect your basement in many ways.
