Being familiar with Concrete Efflorescence How It Leads To Unsightly Foundation Walls
At Permaseal, we respond to customer questions on concrete problems each day. Just about the most frequent, and most puzzling for home owners, is exactly what they should do after they find layers of white-colored, flaky residue on their basement walls. This particular powder is very common on cement surfaces -- specifically in cellars and crawl spaces -- and it is referred to as efflorescence.
What Can Cause Efflorescence?
Cement is a porous material -- and it has been since the day it dried. As a result, it's going to accept moisture from the earth outdoors, gradually releasing some of this moisture into your house. This is most significant reasons that cellars are infamously damp, humid areas.
As this moisture passes through your cement, it brings a small portion of minerals from the earth outdoors in conjunction with it, along with the lime in the cement itself. When it evaporates in your basement, it leaves these kinds of minerals behind. With time, they create the white-colored, flaky dust that you notice on your wall surfaces today.
Washing Efflorescence from Basement Walls
There are many products on the market today which are exclusively aimed at removing unsightly stains from concrete wall surfaces and flooring surfaces. One great way to remove efflorescence should be to rent a pressure washer from a nearby home improvement store and to blend it with these types of chemicals to effectively blast efflorescence off the concrete.
For a less expensive solution, however, you may substitute these customized chemicals using a solution of chlorine bleach. Combined with a power washer, pressure washer, or just by applying with a scrub broom and some work, you ought to be competent to clean off most efflorescence challenges.
Phosphoric acid may also be used to not only get rid of efflorescence powder but also corrosion, grime, unsightly stains, and hard water build up. Even so, phosphoric acid, along with other chemicals, should be used very carefully and with great care.
Protecting Your Basement from Efflorescence
At Permaseal, we suggest protecting your cement areas from efflorescence before an issue comes up. Having said that, if you thoroughly clean already damaged cement, protection can be applied afterward.
Our recommended way to prevent efflorescence is by sealing your cement 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 humidity.
Concrete treatments can be applied as a spray, roller, paint brush, or any other ways, and it dries in 2-4 hrs. It is harmless for inside use in addition to outdoor use, and can protect your basement in many ways.
