Understanding Concrete Efflorescence How It Leads To Unsightly Foundation Walls
At Permaseal, we all respond to client questions on concrete issues every single day. Probably the most popular, and most puzzling for home owners, is exactly what they ought to do when they find layers of white-colored, flaky deposits on their basement wall surfaces. This particular powder is very common on concrete surfaces -- especially in cellars 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. As a result, it is going to take moisture from the ground outdoors, steadily releasing some of this moisture into your home. This really is one of the primary reasons that cellars are infamously moist, humid areas.
As this moisture passes through your cement, it brings a little portion of minerals from the soil outside in conjunction with it, combined with the lime in the concrete itself. When it evaporates in your cellar, it simply leaves these types of minerals behind. Over time, they create the white-colored, flaky powder that you observe on your walls today.
Cleaning Efflorescence from Basement Walls
There are many products currently available which are exclusively designed for getting rid of unsightly stains from cement walls and flooring. One good way to remove efflorescence is to rent a pressure washer from a nearby home improvement store and to combine it with these chemicals to successfully blast efflorescence away from the concrete.
For a less expensive solution, however, you could substitute these customized 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 ought to be in the position to clean off most efflorescence challenges.
Phosphoric acid may also be used to not only eliminate efflorescence powder but also corrosion, grime, unsightly stains, and hard water deposits. However, phosphoric acid, along with other acids, should be used very carefully and with great care.
Protecting Your Basement from Efflorescence
At Permaseal, we recommend protecting your concrete surfaces from efflorescence before an issue comes up. Having said that, if you thoroughly clean already affected concrete, protection can be applied afterward.
Our encouraged way to prevent efflorescence is by sealing your cement walls with a concrete sealer. The product works deep in the pores of your concrete walls and floor surfaces to create a glass-like silicate bond in the concrete.
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 associated with basement humidity.
Concrete treatments can be applied as a spray, roller, paint brush, or any other ways, and it cures in 2-4 hours. It is harmless for indoor use as well as outdoor use, and can protect your basement in many different ways.
