Being familiar with Concrete Efflorescence How It Results In Unsightly Foundation Walls
At Permaseal, we all answer customer questions regarding concrete issues daily. Probably the most frequent, and most puzzling for home owners, is what they ought to do when they find layers of white, flaky residue on their basement wall surfaces. This powder is very common on cement types of surface -- specifically in basements and crawl spaces -- and it is known as efflorescence.
What Can Cause Efflorescence?
Cement is a porous material -- and it has been since the day it dried up. For this reason, it will accept moisture from the ground outdoors, steadily releasing some of this moisture into your dwelling. This is one of the primary reasons that basements are infamously moist, humid areas.
As this moisture moves through your cement, it brings a small percentage of minerals from the earth outside the house in conjunction with it, along with the lime in the cement itself. When it evaporates in your basement, it simply leaves these kinds of minerals behind. Over time, they create the white, flaky dust that you notice on your wall surfaces today.
Cleaning up Efflorescence from Basement Walls
There are several products currently available that are specifically intended for getting rid of stains from concrete walls and flooring surfaces. One great way to remove efflorescence should be to rent a power washer from a nearby home improvement store and to blend it with these types of chemicals to effectively blast efflorescence off of the concrete.
For a more economical solution, however, you may substitute these custom chemical substances using a solution of chlorine bleach. Combined with a power washer, pressure washer, or just by applying with a scrub brush and some hard work, you should be competent to clean off most efflorescence issues.
Phosphoric acid could also be used to not only eliminate efflorescence powder but also rust, grime, stains, and hard water deposits. However, phosphoric acid, as well as other acids, should be used carefully and with great attention.
Safeguarding Your Basement from Efflorescence
At Permaseal, we suggest protecting your concrete types of surface from efflorescence before an issue develops. However, if you thoroughly clean already affected cement, protection can be applied after.
Our encouraged way to stop efflorescence is by sealing your cement 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 floor surfaces, protecting your cellar from both efflorescence and also the water vapor transmission associated with basement humidity.
Concrete treatments can be applied as a spray, roller, paint brush, and also other ways, and it dries in 2-4 hrs. It is safe for indoor use as well as outdoor usage, and can protect your basement in many ways.
