Understanding Concrete Efflorescence How It Leads To Ugly Foundation Walls
At Permaseal, we all answer customer questions about concrete issues every single day. One of the most popular, and most puzzling for homeowners, is what they ought to do when they find layers of white, flaky deposits on their cellar wall surfaces. This powder is very common on cement surfaces -- particularly in basements and crawl spaces -- and it is often called efflorescence.
What Can Cause Efflorescence?
Cement is a porous material -- and it has been since the day it dried. As a result, it's going to take moisture from the soil outdoors, slowly releasing some of this moisture into your house. This really is most significant reasons that basements are infamously moist, humid areas.
As this moisture moves through your concrete, 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 into your cellar, it simply leaves these kinds of minerals behind. With time, they create the white, flaky dust that you find on your walls today.
Washing Efflorescence from Basement Walls
There are several products currently available that are exclusively geared towards removing unsightly stains from concrete walls and flooring surfaces. One great way to get rid of efflorescence will be to rent a power washer from a nearby home improvement store and to combine it with these types of chemicals to successfully blast efflorescence away from the cement.
For a less expensive solution, however, you could substitute these custom made chemicals using a solution of bleach. Combined with a power washer, pressure washer, or simply by applying with a scrub brush and some hard work, you should be competent to clean off most efflorescence problems.
Phosphoric acid can also be used not only to eliminate efflorescence powder but also rust, grime, unsightly stains, and hard water deposits. However, phosphoric acid, along with other chemicals, must be used very carefully and with great care.
Safeguarding Your Basement from Efflorescence
At Permaseal, we recommend protecting your concrete areas from efflorescence before an issue comes up. However, if you 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. The product works deep into the pores of your concrete walls and floors to create a glass-like silicate bond in the concrete.
This barrier stops 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 humidity.
Concrete treatments can be applied as a spray, roller, paint brush, or other ways, and it cures in 2-4 hours. It is harmless for inside use in addition to outdoor use, and can protect your basement in many different ways.
