Being familiar with Concrete Efflorescence How It Contributes To Unsightly Foundation Walls
At Permaseal, we answer customer questions about concrete problems on a daily basis. One of the most popular, and most puzzling for property owners, is what they ought to do when they find layers of white, flaky deposits on their cellar walls. This powder is very popular on concrete surfaces -- specifically in cellars and crawl spaces -- and it is often called efflorescence.
What Can Cause Efflorescence?
Cement is a permeable material -- and it has been since the day it dried up. As a result, it'll take moisture from the dirt outside, slowly releasing some of this moisture into your dwelling. This is one of the primary reasons that cellars are notoriously moist, humid areas.
As this moisture passes through your cement, it brings a small portion of minerals from the soil outdoors along with it, combined with the lime in the cement itself. When it evaporates into your basement, it leaves these kinds of minerals behind. Over time, they create the white-colored, flaky dust that you see on your walls right now.
Washing Efflorescence from Basement Walls
There are several products on the market today that are specifically designed for getting rid of stains from cement wall surfaces and floors. One good way to get rid of efflorescence is to rent a pressure washer from a nearby home improvement store and to blend it with these chemicals to successfully blast efflorescence off of the concrete.
For a more economical solution, however, you could substitute these custom chemical substances using a solution of bleach. Coupled with a power washer, pressure washer, or simply by applying with a scrub brush and some work, you will be in the position to thoroughly clean off most efflorescence challenges.
Phosphoric acid can also be used to not only eliminate efflorescence powder but also corrosion, grime, unsightly stains, and hard water build up. Even so, phosphoric acid, along with other acids, should 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 concrete, protection can be applied after.
Our encouraged way to avoid efflorescence is by sealing your concrete walls with a cement sealer. This product works deep in the pores of your cement walls and floors to create a glass-like silicate bond in the cement.
This barrier halts the movement of moisture through the basement walls and floor surfaces, protecting your cellar 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 any other ways, and it cures in 2-4 hours. It's harmless for inside use in addition to outdoor usage, and may protect your basement in many different ways.
