Being familiar with Concrete Efflorescence How It Results In Ugly Foundation Walls
At Permaseal, we answer customer questions on concrete problems every day. Just about the most popular, and most puzzling for property owners, is what they ought to do once they find layers of white, flaky deposits on their cellar walls. This powder is very popular on cement types of surface -- specifically in cellars and crawl spaces -- and it is often known as efflorescence.
What May Cause Efflorescence?
Concrete is a porous material -- and it has been since the day it dried. For this reason, it will take moisture from the earth outside, progressively releasing some of this moisture into your house. This really is one of the primary reasons that basements are notoriously damp, humid spaces.
As this moisture moves through your cement, it brings a little percentage of minerals from the soil outside the house 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. With time, they create the white-colored, flaky dust that you find on your walls today.
Cleaning up Efflorescence from Basement Walls
There are many products on the market today that are specifically intended for removing stains from concrete walls and flooring. One good way to remove efflorescence would 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 of the concrete.
For a less expensive solution, however, you may substitute these custom made chemical substances with a solution of chlorine bleach. Combined with a power washer, pressure washer, or simply by applying with a scrub brush and some work, you should be able to thoroughly clean off most efflorescence challenges.
Phosphoric acid could also be used not only to get rid of efflorescence powder but also rust, grime, stains, and hard water deposits. However, phosphoric acid, along with other acids, must be used very carefully and with great care.
Shielding Your Basement from Efflorescence
At Permaseal, we recommend protecting your cement surfaces from efflorescence before a problem develops. However, if you thoroughly clean already damaged cement, protection can be applied afterward.
Our recommended way to stop efflorescence is by sealing your cement walls with a concrete sealer. The product works deep into the pores of your cement walls and flooring to create a glass-like silicate bond in the concrete.
This barrier prevents the movement of moisture through the basement walls and floors, protecting your basement from both efflorescence and also the water vapor transmission connected with basement moisture.
Concrete treatments can be applied as a spray, roller, paint brush, or other ways, and it dries out in 2-4 hrs. It is safe for inside use as well as outdoor use, and may protect your basement in many ways.
