Understanding Concrete Efflorescence How It Results In Ugly Foundation Walls
At Permaseal, we respond to customer queries about concrete problems on a daily basis. Just about the most common, and most perplexing for home owners, is exactly what they ought to do when they find layers of white-colored, flaky deposits on their basement walls. This powder is very popular on concrete types of surface -- particularly in basements and crawl spaces -- and it is called efflorescence.
What May Cause Efflorescence?
Cement is a porous material -- and it has been since the day it dried. Because of this, it will accept moisture from the soil outdoors, steadily releasing some of this moisture into your dwelling. This is most significant reasons that basements are infamously damp, humid spaces.
As this moisture passes through your concrete, it brings a small percentage of minerals from the soil outside along with it, combined 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, flaky powder that you notice on your walls right now.
Cleaning up Efflorescence from Basement Walls
There are many products currently available which are especially intended for getting rid of unsightly stains from cement wall surfaces and floors. One great way to get rid of efflorescence should be to rent a power washer from a nearby home improvement store and to blend it with these kinds of chemicals to effectively blast efflorescence off the cement.
For a more economical solution, however, you could substitute these custom chemicals with a solution of chlorine bleach. Coupled with a power washer, pressure washer, or just by applying with a scrub broom and some hard work, you should be able to clean off the majority of efflorescence challenges.
Phosphoric acid can also be used not only to eliminate efflorescence powder but also corrosion, grime, unsightly stains, and hard water build up. However, phosphoric acid, along with other acids, must be used cautiously and with great care.
Shielding Your Basement from Efflorescence
At Permaseal, we recommend protecting your cement floors from efflorescence before an issue develops. Having said that, if you thoroughly clean already damaged concrete, protection can be applied after.
Our suggested way to stop efflorescence is by sealing your concrete walls with a cement sealer. The product works deep into the pores of your concrete walls and flooring to create a glass-like silicate bond in the cement.
This barrier halts the movement of moisture through the basement walls and floors, protecting your basement 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 any other ways, and it cures in 2-4 hrs. It's harmless for inside use in addition to outdoor usage, and can protect your basement in numerous ways.
