Being familiar with Concrete Efflorescence How It Contributes To Unsightly Foundation Walls
At Permaseal, we all answer client questions regarding concrete issues on a daily basis. One of the most common, and most puzzling for home owners, is exactly what they ought to do after they find layers of white-colored, flaky deposits on their cellar walls. This powder is very popular on concrete types of surface -- especially in cellars and crawl spaces -- and is referred to as efflorescence.
What Causes Efflorescence?
Cement is a permeable material -- and it has been since the day it dried up. As a result, it's going to accept moisture from the soil outside, slowly releasing some of this moisture into your home. This is most significant reasons that basements are infamously damp, humid areas.
As this moisture passes through your concrete, it brings a small portion of minerals from the soil outside the house along with it, along with the lime in the cement itself. When it evaporates into your cellar, it simply leaves these types of minerals behind. With time, they create the white-colored, flaky powder that you find on your walls today.
Cleaning Efflorescence from Basement Walls
There are many products on the market today which are exclusively geared towards removing unsightly stains from concrete walls and flooring surfaces. One good way to get rid of efflorescence is to rent a power washer from a nearby home improvement store and to combine it with these chemicals to successfully blast efflorescence off the concrete.
For a less expensive solution, however, you may substitute these custom made chemicals with a solution of bleach. Combined with a power washer, pressure washer, or just by applying with a scrub broom and some work, you ought to be able to clean off most efflorescence problems.
Phosphoric acid may also be used to not only get rid of efflorescence powder but also rust, grime, stains, and hard water build up. However, phosphoric acid, as well as other chemicals, should be used carefully and with great attention.
Protecting Your Basement from Efflorescence
At Permaseal, we suggest protecting your concrete areas from efflorescence before a problem develops. However, if you thoroughly clean already damaged concrete, protection can be applied after.
Our suggested way to avoid efflorescence is by sealing your concrete walls with a concrete sealer. This product works deep into the pores of your concrete walls and floor surfaces to create a glass-like silicate bond in the cement.
This barrier puts a stop to the movement of moisture through the basement walls and flooring surfaces, protecting your basement from both efflorescence and also the water vapor transmission connected with basement humidity.
Concrete treatments can be applied as a spray, roller, paint brush, and also other ways, and it dries in 2-4 hours. It is harmless for indoor use as well as outdoor use, and may protect your basement in numerous ways.
